DGC Map Pack Collaboration

[sorceress]

#9475

I was chatting with Tijn earlier about Doom month, and he suggested the idea of us (DGC) creating our own map pack, as a community effort/collaboration.

While I don’t have a lot of experience with doom map creation, I know some other club members do have good experience with the tools and the general knowhow.

The question is, is there enough interest in our community to create something like this?

I recall a similar communal project was attemped on the doomworld forums a couple of years ago, and what should have been a 1 month collaboration ended up taking almost a year… and those people knew what they were doing!

So I think a full pack of ~30 levels would be very ambitious for DGC to pull off in 1-2 months, and a smaller pack would be a more realistic goal for us.

Reply with your thoughts, ideas, volunteer or whatever. I’m interested to see what we can do together 🙂

#9477

On Doomer Boards they frequently create a map pack in a month, but it’s usually ~10 levels, not 30, and those are some very experienced and talented designers.

As much as I would love to be capable of creating maps, I don’t think I am anywhere near even thinking of it. 🙁

[patrick_wd]

#9479

This idea has been discussed on IRC a bit as well, and it sounds great to me. I agree that a full megawad is overambitious by far, but a smaller doom 1 style single mini-episode is more viable.

I used to do some mapping a long, long time ago, and the tools and tech have come a long way since then. I’m definitely down to attempt to make a map for this.

My personal favorite style of map are the episode 1 style techbases, so I’ll probably do one of those. If there are more volunteers with different preferred styles we could probably arrange them into a loose arc.

[Wesbat]

#9482

Sign me up 🙂

I love me a good tech base.

I agree about a smaller map set. What time-frame did everyone have in mind? In time for the episode release?

It can still be a success even if it’s a work in progress when the episode airs, plus the added stress of a deadline is not always fun.

Of course you don’t want to get stuck in a never-ending cycle either. I will post some tips later to help inform us on avoiding this 🙂

#9483

If this goes ahead you could pencil me in. I haven’t done much Doom mapping, but many moons ago I used to make a lot of Duke3D levels, and I’m sure those skills would transfer pretty easily.

[patrick_wd]

#9484

The Build engine used by Duke 3D is way more complex and janky than Doom. If you have experience wrangling that, Doom should be no problem at all.

Some tips to save time mapping, these are editor agnostic and nothing here is absolute. Take what you will.

The basic steps of building a level:

1) Create the foundation: rooms, locations, and the connections between them.
2) Do a few test runs, adjusting rooms as needed.
3) Populate with monsters and items.
4) Do a few more test runs, balancing as needed.
5) Add flourish, detailing the aesthetics.

* It’s easy to change or reshape rooms, but it gets more time-consuming the more details you have to deal with (lines and vertices). Save time by leaving the fine details for last, allowing you to make rapid changes while the structure of your level is coming together. Also if you start detailing before the foundation has settled, it becomes too easy to lose momentum: your level feels unfinished (there is no exit?) despite all the time you spent making it look good.

Approach: Start with “broad strokes” and create rooms and locations first, optionally apply wall and floor textures where they act as visual reminders of a room’s purpose. Structures that have an effect on gameplay (stairs, lifts, keyed doors, nukage pits) all fall under broad strokes.

* Balance to make sure there is enough ammo and health for the player, and that monsters do not overpower the player. Maps are usually designed for “pistol start”: players who die and restart the level, players who record demos or do speed runs. Balancing also involves setting the easy/medium/hard flags on monsters so accommodate the difficulty level the player has chosen.

Approach: Place the initial monsters for what you consider the medium difficulty level. Play it a few times. How many times did you die before reaching the exit? Do you exit with 100% health every time and a fully stocked backpack? Add/remove monsters & items so you exit with barely enough ammo, and you picked up at least half the health bonuses.

Catering for the easy skill: When you are happy with the medium monster difficulty, select every second or third monster and remove the “easy” flag, this will give less monsters on the easy skill.

Catering for the hard skill: add one extra monster for every 3 medium monsters, setting only the “hard” flag for this new monster.

Balancing is by far the trickiest, I would be happy to assist with this, I’ve done a lot of it 🙂

[dr_st]

#9491

Balancing for hard skill, approach #2 – replace a bunch of Hell Knights with a Spiderdemon! 😛

Since those collabs have an habit of turning vaporware I am going to propose a CONCRETE PLAN OF ACTION.

1. We strive to make at least one episode
2. It has to be DOS Doom compatible
3. Each person shall make one level ideally
4. Level pong is still an idea, then a duet can work two levels at once
5. It is no issue if the level is unfinished – another volunteer can finish/retouch the level as happened in real Doom after Tom Hall left
6. I suggest that we “remake” one of the original 3 episodes, not necessarily an actual area by area but to give a rough idea i.e. E1M2 is nuclear plant
7. I suggest that the first and last maps, which are most prominent, are made last, or by the best mapper(s), or by team effort
8. I think the bar can be held quite low, no need to avoid participating just because you aren’t good at it
9. An idea for map shapes is to make a shape like a letter such as a K shape for KDRNIC

Also, unless there is more PARLIAMENT QUICKLY REACHING CONSENSUS, here is the DEAL:
We will make at least Episode I(1(one)).
DRAMATIS PERSONAE (all that have mentioned willingness to participate, each shall make one level):

kdrnic
Wesbat
sorceress
voxel
TigerQuoll
patrick_wd

Also THIS VERY POST has a line as such:
“March 3, 2025 at 9:00 pm #9491”
I will append to this string a space and the nickname as above, and hash, and sort. This will then be an ordering of maps, from M2 on.

I suggest that we discuss at most until March 10, and then necessarily start work with whatever the plan is at such time.

[TigerQuoll]

#9511

Wow, I like your quick, executive decision making, kdrnic!
Can you just explain the hash string a bit more, what it’s for and how it’s used? I’ve never been part of a collaborative software project like this, and these sorts of procedures are pretty alien to me.

[TigerQuoll]

#9512

Patrick_wd: yes and no.
I’ve tinkered with Doom and Hexen mapping, but never very seriously. Only enough to make some simple two or three room maps and see what it’s all about. This was quite a while ago, mind you, with some of the early DOS based tools, so take this with a pinch of salt.

My impression was it’s a lot more hands-on than Duke3D. The Build editor did a lot of things for you, such as automatically creating/assigning sectors, texturing, and fiddling about with which is the outside/inside face of a wall (forgot the proper terminology). It felt a lot more like you could just create what you had in your mind without having to worry about the nuts and bolts.

Mind you, I imagine a lot of the newer tools for DOOM do this too, so it might not be an issue.

But the other thing was Build didn’t require you to fluff about with WADs and nodes and all these other filesystem level things. It just spat out a map file which you could launch straight into the game.

That said I’m sure all those things are not a steep learning curve. It’s just an extra little thing for me to reorient my way of thinking. I’m sure I can clobber together something playable, but I’m glad I’m not assigned one of the more iconic maps!

[patrick_wd]

#9513

Yeah, modern Doom mapping tools are much more streamlined now. They even have 3D live-previews so you can move around in your map as you edit it and see your changes in realtime. It’s actually quite nice now, nothing like the “2d lines on a canvas until you run the game and hope it looks right” workflow of the 90s.

[Wesbat]

#9516

+1 to @kdrnic for the outstanding Plan Of Action, I like it.

I’d briefly like to mention a few of the map editors available. Don’t take my opinions as canon, I am sure there are many others and I’d also like to hear your recommendations 🙂

I mainly use “Eureka”, a cross-platform map editor. As much as I love it, there are some caveats: not being as prolific as some of the more popular editors, searching for tutorials and help online can take some digging. Also the latest v2 release has some instability issues, I suggest sticking to v1.27b

The more popular editor is called “Doom Builder”, and was also used by Romero when he created his Sigil episode in 2019. This editor has more tutorials, videos etc online, and would likely be a better candidate for new mappers. There are a bunch of video tutorials on its website.

I am going to use Doom Builder for this project as I’ve always wanted to try it.

#9517

I seem to have been volunteered. If I participate, what files do I need to provide? I.e what do I export and send to you? If everyone’s using different editors, there presumably needs to be some common format for collating maps. Also as I mentioned on IRC I’d like to at least experiment with including some custom textures – how does that impact the files I need to provide for the finished map?

[patrick_wd]

#9518

All editors support working in Doom’s native WAD format, so files should be interoperable without issue. Some modern source ports have other formats like “doom in hexen” or “UDMF”, but we don’t need to worry about any of that, just pick standard, vanilla Doom format and it should be fine.

As for adding custom textures, that’s a bit harder if we want to keep compatibility with vanilla. Only the textures from the last loaded WAD are available, which means if we try to add custom textures we lose all of the vanilla ones. This can be fixed by importing all of the vanilla textures into our WAD, which will bloat it significantly, but is doable.

[Wesbat]

#9520

@voxel you only need to provide the WAD file containing your level. When all levels are done, we use Slade, a game resource editor, to compile them all into one single WAD file.

[sorceress]

#9523

I did actually start putting together my own ideas for a level pack. Coming more from a Doom II background, my ideas are a bit more inspired by that, but only loosely. Take it or leave it. :p

level 1: base station
– a short introductory level with an iconic design.
– pistol zombies and imps only
– easy navigation with 0 keys
– pistol only, shotgun may be found in a secret area
– no hazardous floors

level 2: storm the castle
– introduce shotgun zombies and demons (pink monster)
– easy navigation with 1 key
– give shotgun early on
– no hazardous floors near to the action

level 3: castle gardens/ruins. mostly outside areas.
– introduce chaingunners
– two areas that can be done in either order, giving 2 keys to enter a final area/bunker
– get chaingun from chaingunners
– rocket launcher in secret area
– no hazardous floors near to the action, but non-damaging water floor is ok.

level 4: tunnels/sewers
– introduce spectres (invisible monsters), lost souls, and a lone hellknight as a practice miniboss mid level. (he’s relatively weak)
– less easy navigation with some backtracking, with 2 keys
– give super shotgun mid-level, which can one-shot demons + spectres at close range.
– have some poison floor areas where the action is, and give radiation suits for them.

level 5: the baron’s lair
– introduce baron of hell as a miniboss at the end of this level
– perhaps make it clear early on where the miniboss will teleport in, to build up a sense of foreboding. like an arena. a vision trigger might lure the baron into a teleporter, and so into the arena. but a switch might first be necessary to make the teleporter accessible to the baron.
– last of the “easy” levels. 2 keys
– give rocket launcher. beware of giving the player too many rockets prior to level 10. they should feel in limited supply.

level 6: the hell maze
– introduce cacodemons, and bring hellknights back as a regular unit.
– medium difficulty. more complex map layouts. 3 keys
– some hazardous floors you have to cross, without radiation suits.
– hard to find secret areas. include a map reveal towards the end, so that you can locate them. reward backpack in one of these secrets, red armor in another, and heath packs in another, to bring you to full health.
– starve the player of ammo towards the end, so that we start fight club with very little.

level 7: fight club
– introduce revenant
– revenants use their fists at close range, and it’s quite fun to engage with them 1v1 in close quarters like this.
– plenty of berzerk packs to encourage the player to reciprocate the fist fight in the early game, combined with ammo starvation from the end of the previous level.
– revenants use homing missiles at distance, so ensure you only meet them close up by keeping them hidden out of sight around corners etc, or starting with their backs to you.
– later on, you need to find cover from groups of revenants because you can’t out-strafe their homing missiles at a distance. and you should be given ammo for that (and cover).
– i think it would be fun to design one level around engaging this special unit.
– medium difficulty. 3 keys

level 8: mecha-spider lair
– introduce arachnotrons
– arachnotrons can create bullet-hell stages with their endless barrage of slow moving projectile. they’re fun to out-strafe though, so design the level around that.
– continue to starve the player of rockets, so they can’t solve it that simply. must rely on shotgun + chaingun.
– a bit of a maze with tunnels, chambers, lairs, and lots of spiders. it wouldn’t be much of a spider lair without some traps either.
– include a couple of invul spheres so you can break through deliberately tricky areas.
– medium difficulty. 3 keys
– reward plasma gun near the end

level 9: bridge over the river styx
– introduce pain elementals
– pain elements (and the lost souls they spawn) are not particularly fun enemies to deal with, so have them but don’t focus too much upon them.
– there is a cap on the number of lost souls active in a level, and you could design the level around this – a knowledgable player might opt to leave an area with lost souls until after they’ve dealt with the pain elementals. or to trigger some pain elementals into spawning their lost souls, so that others in a more tricky area will not.
– include a dark area, and give vision glasses.
– medium difficulty. 3 keys
– give plasma gun

level 10: temple of fire
– introduce mancubus and archvile
– mancubus throw lots of fire, and archviles like to burn the player at range via a channeled spell. they also resurrect the fallen. this is a good recipe for a chaotic and deadly level!
– hard difficulty. 3 keys
– give bfg and plenty of rockets. fight fire with fire.
– include deadly lava floor areas
– include a couple of invisibility spheres so you can better position yourself for engagement, or sneak past the enemies to get essential ammos.

level 11: the library
– bring baron of hell back as a regular unit (earlier miniboss)
– hard difficulty and longer, with more close quarters combat. 3 keys
– give plenty of rockets now, despite them being hard to use in close quarters. the player can use them where they feel confident or if they enjoy the gamble.

level 12: finale
– introduce cyberdemon
– boss arena. 0 keys
– plenty of chaingun ammo + some rockets. defeating the cyberdemon with the bfg is unrewarding, but with shotgun alone would be painful.
– DGC lettering cut into the ground, which you can look down on from a higher platform when you’re done.

[Wesbat]

#9525

@kdrnic I totally agree with you, the first and last maps should be a team effort, that sounds like fun!

You didn’t mention E1M9, the secret level. Perhaps that can be on reserve for anyone else wanting to join the fray? Otherwise it can either be skipped or become a team level.

We can also use the number of weapons, items & monsters of the original levels as a *guideline* when placing them in our levels. This ensures play at a similar difficulty than the original game, and saves time fussing with balancing. Totally optional.

(List of Things for each level is at https://doomwiki.org/wiki/Knee-Deep_in_the_Dead – click through to the level, then scroll to the “Statistics” section)

[patrick_wd]

#9526

I agree that it’s a good idea to keep difficulty roughly in line with the original, at least for normal difficulties. The Doom community has been around so long at this point that many community projects tend to be extremely high difficulty with massive arenas and huge waves of monsters that can be quite fatiguing even with save-scumming. Vanilla style monster density should make it accessible to most any player, while we can always reserve UV as a more challenging option.

[patrick_wd]

#9529

Here’s another idea to add to the pile. It’s possible to make a single player level double as a deathmatch map by adding a region disconnected from the rest of the map. Placing the deathmatch spawnpoints and multiplayer-only items there makes it effectively 2 maps in 1. Romero did this for his Sigil maps and it works quite well.

We could all add simple deathmatch arenas to our maps and use the DGC map pack for a tournament or something. It doesn’t need to be anything more complex than a big square with some walls and pillars in the middle, but feel free to add whatever unique twist you want.

[kdrnic]

#9537

I suggest a timeline where we have a rough level by 21 March at the latest so the remainder of March can be used in glueing the levels together, finishing touches, possibly some style of “level pong” (as in code pong)

I think I can’t stress it enough, that if time or inspiration seems short we can just lower the bar, since the fun is in having made such a thing at all, rather than having made a PRO QUALITY thing, as in a game jam.

( @sorceress I think we agree on making a Doom WAD so avoiding Doom II stuff )

Oh man, you guys’ maps look so good! And you’ve all made heaps of progress!

I’m still wrapping my head around the editor and regrowing my map editing brain, and I’ve only managed a few very ugly sectors so far…

I was looking for inspiration for a layout, and for some reason I thought the cover image of Douglas R Hofstadter’s book “Mathemagical Themas” would be good because it looks kinda maplike.

Google it and I’m sure you’ll wonder how I could be so deluded…
I’m thinking of treating it as a learning exercise and starting again with something that has the occasional right angle and respects euclidean space.

This is only a suggestion, but can we use a shared document to leave testing feedback on each other’s levels?

This is also to collect the level download links in one place, to make it easier for when the time comes to package them into a single WAD.

I am hesitant to make the doc publicly editable. For now use the “Request Access” button. Apologies for this hurdle, I’m open to other means of coordination too (or not) 🙂

Edit: link removed in lieu of @kdrnic’s excellent suggestion

[kdrnic]

#9562

@Wesbat I am not sure it is necessary, since we can aggregate all discussion/feedback within this forum thread. I hate those 2000s forums with dead links to long gone interesting information.

Since posts are editable, I can make a post such as a table, and edit to include further updates.

I have my own level complete/ready for testing… I tried to make an industrial style area to fit the REFINERY theme. It took some more time than I expected, but at the same time the level is a bit longer than I thought it would turn out.

I am not sure whether it is best to release each level to be tested one by one – I thought of having a deadline. I suggest no later than Friday, March 21. So we have the last 10 days of March for “glue up” and finishing touches.

@patrick_wd has mentioned also being almost done, so maybe we can discuss starting a collaboration on E1M1 as planned, and E1M8/E1M9, which went unclaimed.

Some ( @sorceress @voxel @TigerQuoll ) have mentioned getting-used-to-editor troubles, I hope and urge all can at least make something small; being the intention that matters, and someone else, if desired, can volunteer to retouch or lengthen the contributed level.

Lastly, I think we can add some small DGC flavour – either a DGC-styled room, or maybe a custom texture – to every map. For a custom texture, I think it is possible to replace (but not to add?) a “texture patch” (rather than a “texture”) in a vanilla PWAD, without necessarily importing/merging all default “texture patches”. So we could pick a “texture patch” which is unused in any of the contributed levels, and reskin it.

Well put @kdrnic, I cannot argue with link rot 🙂

As for custom patch/textures, one requires the PNAMES and TEXTUREx lumps, this applies to new patches and replacing existing ones equally.

This adds around 20kb of book-keeping overhead to the WAD (not counting your image of course). Without these, the engine will seek the graphic data within the IWAD and overlook our PWAD.

Did you have the DGC logo in mind? Sounds a fun idea. Need any help with this? 🙂

#9565

Here is my E1M5, all skills implemented and equal the original game’s difficulty.

[patrick_wd]

Here’s mine: E1M6

Difficulty is slightly harder than vanilla. Many secrets are available to help, but the map is still reliably beatable with 0 secrets on HMP or below. UV is significantly harder to provide more of a challenge.

I can confirm that i am working on a map, but i haven’t used E1M4 as a guide at all. I was actually hoping we’d make a Doom 2 map pack, but it looks like that idea now has been rejected 🙁

I couldn’t even remember what E1M4 was, tbh, But i have played through it, and I will endevour to produce something similar in size, content, and hopefully quality.

I aim to have it done by the weekend. 🙂

I recorded each first finishing on demo files, and I suggest other playtesters try this.

@Wesbat ‘s map, having played his other WAD, has a distinctive Wesbat style, which is much to my taste. Probably everyone has a distinctive style, when mapmaking.
I did fall once into the cheeky trap – but I can’t say there was a lack of warning.

I am very impressed with the size of @patrick_wd ‘s map – entertainment for 19 minutes!
At one point I was a bit lost in a computer/cubeish area – maybe something can guide the player’s eye.

I actually really enjoyed watching that; very suspenseful finish! It also illuminated a few issues that I’ve since addressed in prep for the final release.

@kdrnic thanks for the demo!

I am sorry about the teleport death-trap. That was very cheeky (and borderline troll). I have removed it from my map 🙂

@patrick_wd, I love your map! I died on my first attempt, I will record a demo on my next play and share it here.

[kdrnic]

#9575

@Wesbat put it back!

[patrick_wd]

#9576

Unfortunately I didn’t even think to record blind demos of my playthroughs, but I kept a notes document as I was going. Here’s what I have so far:

E1M3:
Really sells the industrial/nuclear waste facility vibe quite well. All the barrel clusters and piston elevators are a nice touch.
Item pacing is a bit tight and sparse. Some more stimpacks and bonuses dotted around here and there would help a lot. Bonuses are also a good way to guide the player like coins in Mario.
Once you reach the primary exit, there doesn’t seem to be a way back to the rest of the map. Once I secure the exit I like to go back for secret hunting, but I had to noclip back out to do so. It’s possible there is a way back and I just missed it.
-EDIT-: Forgot the mention that it feels like the chaingun is a secret, but it isn’t marked as such. Perhaps it’s intented to a “soft secret” instead.

E1M5:
That central room with the nukeage pit and 3-point shadow is really striking; great stuff.
The green doors in the green area seem to use the fast open action from one side, but the slow open action from the other. Not a big deal at all really, but it’s something I noticed.
Noticed a bit of oddness in the automap with some parts of certain rooms were invisible while others were not. Perhaps intentional, but worth mentioning.
I actually got a good laugh out of the death teleporter. I knew it would kill me but I couldn’t resist and took it anyway. Nobody to blame but myself. A shame to see it go, but I understand why.

[Wesbat]

#9577

@patrick_wd here is my second attempt demo. I still haven’t found all secrets yet, and I really enjoy playing it. The Hurt Me Plenty difficulty plays more like Ultra Violence. I did not spot anything odd, but will have a few more run throughs, taking my time and paying more attention 🙂

e1m6_wb_playtest.lmp

A general note to everyone: you have to play back demos on the same map revision it was recorded against, otherwise the demo goes out of sync. For this reason its a good idea to keep copies of each revision you push out.

[Wesbat]

#9578

@sorceress looking forward to play your map. And depending how this project goes, who knows … we may be keen for a Doom II edition in the future 🙂

[Wesbat]

#9579

@kdrnic here’s a demo for you, HMP e1m3_wb_playtest.lmp.

I like your use of heights. The exploding barrels provided a good amount of careful damage control. I found myself hunting for health halfway through, perhaps a few more health packs wouldn’t go amiss but that is hardly a flaw and I really enjoyed it!

[sorceress]

#9580

After playing through E1M4 a couple of times now, I’m trying to think of ways to modify my design to more closely reflect the “Command Control” theme. So that’s my task for tonight. I’d like to get the bulk of the mapping done by tomorrow (wednesday), so that I have all of thursday and friday for balancing (monsters + pickups) and general polishing.

I’ve been also been having a lot of trouble with triggers while crafting this map (among various other editing woes). For example, the texture of switches doesn’t seem to update automatically when operated, and I can’t figure out how to swap them. Getting the exact behaviour i want is also taking a lot of guessing and giving up.

Eureka doesn’t explain the triggers at all, and the huge list of them i found on doomwiki is both unreadable and lacks important behavioural detail such as sounds and things. A (visual) scripting system would have been much better than what we have to work with here. I hope someone else can fix these things for me after I upload.

This is my also first time making a doom map, and I’m finding it a lot slower, and a lot less intuitive than I had expected. But I’m determined to cobble together something half-decent this week!

[patrick_wd]

#9581

I got hit with the switch texture problem, too. To fix it, make sure only ONE switch texture is used by the linedef (as in only the lower, middle, or upper texture). If, say, both the upper and lower texture are a switch, then it won’t work.

The linedef actions are indeed a bit of a mess. They were basically iD adding whatever they needed at the time in an ad-hoc manner, which is how we end up with some of the more strange actions like donut. One thing that really helps is to open the vanilla maps in the editor and inspect which actions they use and how they’re set up. I used E1M9 as a reference a few times to figure out how to do certain tricks.

[Wesbat]

#9583

Sorry to hear you are having troubles @sorceress.

We can certainly fix these after you upload, or help guide you, if you want to do it yourself? Feel free to describe what you are trying to create, and I will gladly give an example map with steps; it could highlight what the trouble is.

For switches, in addition to the good tips from @patrick_wd:

– Use textures that start with “SW1…” (switch #1), the engine will swap its texture out automatically by replacing SW1 with SW2. We can’t control the swap behaviour, it’s hard-coded in the engine.

– “S” actions (Switches) only work from the *front* of the line (the little “handle” on the line faces towards the front). In Eureka the W-key flips the line front-to-back.

– Make sure to pick one-time (S1) or repeating (SR) switch actions accordingly, and that the switch and target sector have the same tag number.

Most map editors don’t explain how the Doom engine works, which only creates a barrier of entry, very silly indeed. The wiki is only useful insofar as as quick reference. The main source of truth is the “Unofficial Doom Specs”, a technical document by nature. But we don’t expect newcomers to read through it, it is a dry read. Please ask us question, we will be happy to help 🙂

I have made a slightly updated version addressing a few concerns:
-You can now go back from the exit area, this is an useful convention.
-Added a tiny peppering of health on HMP and lower.
-Marked the chaingun as a secret.
-Added one extra barrel to help with one speedrunning bottleneck.

#9586

Calling it a day on my map. It’s probably far too easy for you DOOM pros but it’s just about right for me, and I figure E1M2 in a mappack doesn’t have to make players sweat. I’ve tried to limit the available weapons to allow for *some* progression through the episode, but I’m not going to cry if you stuff every single weapon into E1M1 and the player arrives at my level having already attained godhood. Much.

It was fun learning my way around the tools (I used SLADE) and working with the DOOM engine restrictions – and I’m interested to see how my limited DOOM experience causes my map to differ from the output of veterans of hell. In particular I was unaware that ‘real’ DOOM has no jumping other than ‘run really fast and hope you make it to the next platform’, so that really limited my initial plans. Also why is there no water texture for use on walls? Ridiculous! In protest I have animated a grill sideways, live with it.

I’m still way behind. It’s been a crazy busy week at work. But I’m getting the feel for the editor now, and hopefully I should make some good progress over the next few days.

I agree we should add some little DGC touch, but not sure what that should be…

[Wesbat]

#9593

That is a really good looking map @TigerQuoll. Nice teaser 🙂

@voxel your WAD has a few minor problems preventing it from playing in Chocolate/Crispy/Vanilla Doom.

– missing bsp node data. usually your map editor of choice creates this during save, but I guess these were removed? I opened + hit “save” in Eureka to generate these.

– sectors #66 and #208 incorrectly uses *textures* PIPE2 and BROWN96 as *flats* (sadly these are not interchangeable).

– sectors #223 and #330 are missing tags (switches and their target sectors must have matching tags).

Not sure which editor you use. Eureka (F9) and Doom Builder (F4) can check for and report map problems, this helps pinpoint mistakes easily.

[kdrnic]

#9594

I fixed the @voxel WAD a bit in DB2 and did a playthrough

I think I may have accidentally skipped some content? Maybe some walls/boxes lowered that weren’t supposed to.

@Wesbat thanks! I’ve managed to find the somewhat hidden mapchecker in SLADE and found the issues you mentioned (and more!). I even installed zdbsp for node building, you spoiled babies. Back in my day we pulled out a pencil and paper and built our nodes by hand each time we wanted to play a map.

I just played through the map in chocolate doom (where the fov is slightly different to gzdoom’s default, making the claustrophobic sections even more so), and all seems OK to me.

(edit: I guess the nodes weren’t in the wad. I’m not sure how this works but *this* wad definitely plays for me directly in chocolate doom)

https://drive.google.com/file/d/19-bLoaOtvpqV0jt72fduUHapni6Zv2dw/view?usp=sharing

(it is vaguely reminiscent of default E1M9)

I figure if everyone is willing,
we can use this central hub model,
I can have the East wing,

@Wesbat the west bat can have the West wing,
and @patrick_wd the South wing.
(or some similar arrangement as long as @Wesbat keeps West, if he is in).
If someone chickens out or joins in we can just re-distribute.

This also potentially allows us to “merge” the map, if two people work on it at the same time.

We can use some wacky system of tags such as:
kdrnic 100-199
Wesbat 300-399
patrick_wd 400-499

There is an open position for the NORTH WING, tags 200-299.

Switched from SLADE to EUREKA and made a pass to fix ‘medusa’ and ‘tutti-frutti’ textures. I’m going to wait until the pack is ready to be compiled before playing through the other maps, I want to be able to play through the episode ‘legitimately’ free of prior knowledge

@voxel your map is great! I love the subterranean mood at the start, and the traps got me good 🙂 I recorded a demo on ultra-violence.

@kdrnic here is a link to version 2 of my e1m5:

– Added a way to get back out of the exit room
– Fixed mapped lines & doors opening the same from either side (thanks @patrick_wd)
– Added a deathmatch arena!

Edit: Count me in for the west wing of E1M9 🦇

[voxel]

#9603

haha thanks @wesbat. originally the lift in the first room was a ‘use once’, and I hadn’t realised until watching you play that you could skip half the map if you simply walk back to it after getting the red key.

I made the change to make deathmatch more feasible, but as far as single player it’s a massive design error on my part, doh!

edit: updated with anti wesbat shortcut measures https://thomaspurnell.com/notes/voxel_e1m2_20250320_4.wad

#9604

Idea for E1M9: 3 of the wings have a keycard to obtain, and the final wing requires all 3 keys to reach the exit. In the original map, the south wing contains the blue key, so I’ll add that to mine.

EDIT: Also, since this is the secret level, I’m going to try something weird and experimental. I encourage everyone to do something crazy you’d never do in a “normal” map.

I’m quite pleased with what I’ve put together this past week, and it feels as fun to play through (for me) as some official doom levels.

It takes me ~9 minutes to do a 100% run on UV, and ~2 minutes to speedrun it.

I’m hoping someone (or two) will put a let’s play up on youtube. I’ve love to see my map get a good playing! 🙂

I tested the @sorceress map

I think it is possibly slightly broken?
Did you test with Chocolate Doom?

The very first door refused to open, until I modified the sector slightly in Doom Builder 2 (see pics).

At the very end, after opening the exit door but before pushing the exit switch, I got a hall of mirrors effect.

At the start, the map was a bit short on shotgun ammo.

Here is a demo, I accidentally played on HMP:

#9614

The shortage of shotgun ammo early on is intentional, as i’ve tried to create a steady build-up of tempo, and have the player be mindful of how they’re spending their precious shells. The early game should leave you feeling a bit timid, but progress rewards and emboldens you. You shouldn’t be short of pistol ammo, unless your aim with the pistol has been lousy. :p

[kdrnic]

#9615

Right, the pistol is traditionally entirely skipped

I managed to almost finish at UV but got stuck on the exit:

Apologies for the broken link @kdrnic, I corrected it in my post.

[Wesbat]

#9619

E1M4 looks great @sorceress! I love all the secrets and traps, and it gave a good feel for a base of operations. I recorded a demo on ultra-violence.

“Hurt me Plenty” plays hard though, I can see it frustrating casual players. Sixty percent of the monsters in your map use hitscan (bullet) attacks, which make play harder as the player cannot dodge these attacks. The average in vanilla Doom is 34%

You can leave the difficulty as is for the Hard skill, but for Easy and Medium skills consider changing a third to half of the shotgunners to Imps (or removing them from those skills altogether).

It’s just a suggestion of course. Casual players will carry weapons from previous levels and also have save games, so I dare say you could get away with this difficulty. It may just feel out of place amongst the other maps.

I also fixed your exit door, it needed a tag as its operated as a switch. I used the WAD linked by @kdrnic so it has all his fixes too.

#9621

Hi Wesbat, thanks for your feedback 🙂

Firstly, I’ve been testing the map with zdoom, and I was unaware that different engines have different rendering & physics limitations.

I’m not sure how to load custom maps in chocolate doom. I’ll have to look that up.

– Difficulty

I was aware that HMP plays a bit hard, but I decided to leave it as is for first submission. I mostly tested the map on UV, and I’m quite happy with how that plays, even if it is numerically a bit different from classic Doom (as per your analysis).

I’ll consider your advice though with the hitscan types. Either reducing their numbers a bit, or replacing them with Imps.

– Ammo

I’ve tried to leave the player with a bit more ammo by the end than what they start out with (the 50 bullets). I’d agree that if a player starts this map short on ammo, they might struggle to survive the first third of it. I’ll also think about that.

I agree that you can’t dodge hitscan attacks, but you can limit your exposure, by taking cover. Not even I would brave running out of the tunnels into the middle of those shotgunners!

It’s important to note that hitscanners are more a source of ammo than a drain, and in my map they adequately make up for the lack of placed ammo pickups.

The interaction with balance and pacing of the game is also complicated, since hitscanners are easier kills than imps – You can often down 2 hitscanners with 1 shotgun shell, whereas an imp may take upto 2 shells if you don’t hit it square on. This affects pacing, and thus the damage the player is taking over time.

I’ll continue some fixes this weekend.

– Map Making

I think I spent about 25 hours on this map over the past week (3-4 hours each evening), which has been quite a challenge.

I had a hard time with Eureka though. Part of that may be inexperience with it (plus inexperience with Doom map making in general). But there were inexcusable bugs like the text entry boxes losing focus when my mouse drifted away from them, causing my keystrokes to be interpreted as hotkeys, creating all manner of unintended changes in the map. I’ve literally lost over an hour to that alone. Switching between modes to select things is also painful, and I’ve never used Ctrl-U so much in my life before :p

There were three rooms that I removed due to quality concerns, which were some of the first areas I made, despite them playing well.

The exit room was one of the final additions, so I’m not surprised it didn’t connect properly.

I just tried to search for this analysis tool you’re using, and I found something which looked like it – dmon on github. Then I noticed the author’s name… would that be your good self? 😀

[kdrnic]

#9622

@watchful it was a “soft” deadline or a suggestion

we still have a bit over a week, but the sooner we pack it up, there is more opportunity for people to play the WAD, before DGC attention turns to the next, less remarkable, game.

Can someone help me debug the exit on my attempt at E1M8?

I can’t find any reliable way to get it to exit, except damage to 20% (action 11). I was hoping to have a linedef walk exit at the edge (52).

Maybe sectors are too large, or too many moving sectors, or my editor being buggy (Ultimate Doom Builder), or CrispyDoom quirks? IDK.

EDIT: Nevermind, I just had a oversized sector.

Ok, I think I’ve finished my M9 wing. I make no apologies: E1M9 South

Also, I’ve revised my other map based on feedback and I think it’s ready for final release barring someone finding a major bug or softlock: E1M6 RC1.

[Wesbat]

#9628

@watchful gosh that certainly is a curious problem you encountered. It had me stumped for a while!

I looked up the static limits for map Coordinates:

> In practical terms, it is safer to keep the map
> boundaries between -16384 and +16383.

Moving the sectors of your final boss area to within these coordinates fixes your problem.

@sorceress yes indeed I created the dmon tool 🙂

[watchful]

#9629

@wesbat much thanks!

I stumbled into that by downsizing my largest sector. That said, I appreciate the precise number of the limit.

EDIT: If folks want to test my map, here is a functional copy. It lacks some decorations and probably sign posting. For the curious, I’d call it “Ashes over Babel”. There are some visual glitches on wide monitors, or if folks travel out over the water but it works well enough for me on CrispyDoom. Please LMK your thoughts!

[kdrnic]

#9630

Alright, I’ve merged the South/East/West wings of E1M9

Also, there was the idea of the DGC touch.
Could be one of those things:

-A patch/texture hidden in every map.
-A “DGC room”, maybe with DGC written in the carpet floor, we add to every map.
-Could hack the sprite of one unused decoration, to be that DGC computer, we add it to every map.

At any rate it needs doing SOON. What are the opinions of all?

We are nearing a first release, as soon as we have E1M1/E1M7 and a more finished E1M8! Hurrah!

#9631

Replace all grunts with a Tijn sprite and all Cacodemons with rnlf?

Or less effort, replace one unused environment texture with the DGC logo as suggested and either include it as a secret or perhaps put it next to the exit of each map?

How about compiling the forum avatars of all the mappack authors (and their names, if it fits) into a single wall texture, and then with some careful setting of x/y offsets we can each stamp our own map with our beautiful visage, as well as including the full texture in the final (or secret?) map as a kind of group credits.

alright, before i fall asleep, here’s an update to my map:

rev06 – https://app.box.com/s/xlk477xzz5sygg5hrdeygxu2xcx4iix2

features:

– fixed the glitch on the start door when played in chocolate doom. it was apparently caused by an unrelated trigger being too close to the start location. who would have guessed this stops a door opening!

– fixed the missing texture above/behind the exit door.

– fixed the tutti-frutti textures. mostly via replacement, some by changes of geometry.

– fixed some annoying bits of geometry, and moved some triggers.

– slightly reduced the number of scanline shooters, to help address wesbat’s concerns.

– reduced the imp count in the early game. this makes the limited shotgun ammo go a bit further, as well as creating a more gradual ramp in difficulty.

– increased the imp count in the mid and late game

– increased the number of deathmatch spawn points to 6, and placement of deathmatch weapons.

– changes to placed items, to rebalance the game after the monster changes. the rockets are also more accessible midgame.

– prevented monsters from discovering secret areas.

– tested all three dificulty modes, including a zero ammo start on UV. all runs were readily doable and felt correct difficulty to me. and with all runs i had a bit more ammo carried at the end than i started with, which is how it should be i think.

#9641

Apparently DOS (vanilla) Doom won’t work without the DCG.wad if those textures are used on a map. So here’s two latest copies of my E1M8 map:

• E1M8.wad — no DCG textures
• E1M8DGC.wad — with DGC textures

May also help if the DCG.wad sample map were placed into a different map slot, perhaps E2M1, so it won’t overlap any real maps.

EDIT: Sadly now that I’ve tried DOS, the large ocean sector is still too big. Here is a DOS-playable copy which also had to drop the DGC text in the secret. Sorry everyone, I just don’t have time to polish/fix this any more 🙁
