Things about Doom you just found out

[Maximum Matt]

I just realised that in Ultimate Doom, exit buttons are used every level of Episodes 1 and 2, but exit teleporters are used in Episode 3.  Seems obvious but it never clicked until right now.  

(And of course, mongrel-ass Episode 4 uses a combo of both - and the otherwise completely uninteresting Unruly Evil (E4M4) is the first example of a "sky floor" exit)

E2M9 uses an exit teleporter while the secret exit in E3M6 is a switch.

Ehhhhh.... close enough

E1M8 uses the death sector exit.

Doom 2 used sky floor exits before Ultimate Doom.

E2M9 is a very weird level in many ways. It feels like there should be an interesting story behind it, but unless more pre-release stuff resurfaces we probably won't find out.

Well, that one obviously doesn't count.

Yep, and in the beta(s), there were actually a few more, like at the end of the Factory and stuff

Well, it is mysterious :-)  There's only so much lore you can put into a level that consists of just two rooms

[Shepardus]

I just found out that having Tome of Power (in Heretic) or Boots of Speed (in Hexen) active allows you to move immediately after teleporting instead of being frozen in place for half a second (or until taking damage). I've noticed that happening before, but only just connected that to the Tome of Power (and I've never used the Boots of Speed in Hexen).

[Zesiir]

That the BFG 9000 can be shot from behind walls. As long as you get into view of monsters before the effect ends, it does tremendous damage.

 

Cheesy for sure. But some slaughtermaps depend on tricks like that.

[CacoKnight]

Here is a funny one, when I started playing Doom last year it took me like a month to figure out that it wasn't the soul sphere that was making the noise but it was the imps inside E1M3' secret room.

[plums]

In vanilla Doom, crushers were meant to shoot blood in all directions from the object being crushed, but don't because of a coding error. In Boom they fixed this so that the blood does shoot out. See this recent video by decino: https://youtu.be/7EAAtm_9rqs?t=682

 

The thing I just found out: a funny side effect is that the blood flying out can teleport, mainly in demo-compatible ports. (i.e. dsda or Woof but not GZDoom).

@plums Can't wait for someone to use this on a MAP30 to telefrag monsters or the player.

LMAO THAT ACTUALLY WORKS! Requires complevel 9, or comp_telefrag 1 option on for MBF/21

just found out how awesome the texture [shawn2] and flat [flat23] are :P

I learned about how fake contrast brightens and darkens walls that are exactly parallel to N/S and E/W axes on the map grid.. and how @EduardoAndFriends pulled off his monster teleports in Deep Breath. Very interesting technique!

I’ve now improved upon that somewhat scrappy method as it was held together with sticky tape and prayers. A lot more reliable now lol. :)

That a revenant would be almost 3 meters tall in real life :O 

Thank you to @EduardoAndFriends for an excellent analysis video as the source of lots of great info of that nature:

That ZDoom format allows you to put ceiling/floor textures on walls. And vice versa.

 

I don't think I'm going back to Boom.

Icarus Alien Vanguard mappers getting a hard one looking at this.

[Amaruψ]

Well... not about Doom, but Hexen. 

I found out that if two enemies collide together if you push them away with the ring of repulsion, they'll always instigate in an infight. Plus, Cleric's serpent wand leeches off health from the enemies at melee range. That's honestly a pretty neat feature, if you ask me.

I just now discovered that the Doom Marine sprite has some brown stains on the sides of its trousers

 

Sure, you may get a lot of blood, but that drys out. But you know, I’ve found that imp skin tends to stick around and it is annoying as hell. I just bought those trousers!

If you are working with custom textures, cant you simply add separate patches for the respective flats? That Just seems like a very weirdly specific reason to like ZDoom.

I've no idea. Feels like you should be able to, I've only ever worked with vanilla textures in UDB.

I like ZDoom for other qualities, of course. Like the more options for editing.

Lemme just pull this up from a few years ago

Alright, this is a bit of a conspiracy theorist entry, but.

Fortress of Mystery only shows up on E2's progress map once you've discovered it (i.e. pressed the secret exit switch in E2M5.) And it appears to be a replica of the still-mid-building Tower of Babel, despite the fact that at this point of time we're not exactly seeing yet how the latter would eventually turn out.

However, the actually mind-blowing thing about this is that both groups of monsters in the map have the combined health points of a Cyberdemon each.

Is this some early demonstration of "look bud, this is how much ammo you're gonna waste on the boss of this episode unless you make these tough baddies infight and/or take advantage of splash damage to which said boss is impervious anyways"? Like, this in this sense seems highly likely to come together... sort of.

Also I have a very slight and bit shoe-horned clue about the lame and slightly obscure skullkey puzzle sequence to exit the level. This might be a prelude to E3 where skulls are exclusively used for locked doors (not to mention, canonically this is the first level you encounter skulls in because E2M6 comes right after this) you exit the levels via stepping on teleport pads and the overall means of progression is somewhat cryptic or at least abstract compared to what we've seen previously in the game.

Yeah, call me the VSauce of Doom at this point by a far stretch of course.

[Stupid Bunny]

This is also not so much a discovery as an unsubstantiated theory and I’m crossposting it from another thread but

 

Were the markers for Mt. Erebus and Unholy Cathedral switched at some point in development? The clifftop lava lake on the intermission map seems much more like Mt Erebus (which takes place in a lava lake), and that ruin up there on the dusty, lava-less hillside with the tower feels more like a cathedral, unholy or otherwise. This also makes more sense in terms of the order of levels: as it is, Doomguy runs all the way across the blood river to the cathedral that looks like a lava mountain, and then all the way back to the dusty hill and then back again. He would kind of zig and zag if they were reversed, but not as much, instead kind of closing in on Dis more. The idea of a hellish cathedral being a giant lava mountain is kind of cool but it just seems more intuitive if they’re switched around.

That ACS scripting and UDMF are freaking gorgeous, like, I knew it by looking and playing some of the advanced maps / mapsets, but I never touched these things in the editor until now and you know - I'm highly impressed, you basically can do everything you want, purely everything, it's insane!

I was the same way when I first played lol.
