Things about Doom you just found out

[terminator]

"In any game that uses the Doom engine, linedefs can be activated regardless of the player's Z position. This has the side effect of allowing the player to flip a switch despite being at too high or low of a height to reach it, or even if it is hidden in the floor. In certain maps, this can provide a shortcut of some degree depending on what the switch does." (source).

 

just knew about it today :P

[QuotePilgrim]

Only the other day I realized Marine's Best Friend is called that because of the expression "man's best friend", referring to dogs, because the source port adds dogs to the game. The only reason I ever made that connection is because of Fabian's WinMBF fork, Woof.

 

For something that's more related to the vanilla game rather than source ports, in the same day I learned about the MBF thing, I saw someone mention "slime trails" for the first time, and shortly after I realized the glitch I was seeing in the map I was working on was probably one of those and it was likely caused by my using of ZenNode, so I decided to start using either ZokumBSP or ZDBSP.

x units of blue armor is better than the same x units of green armor

Not so much a thing I found out now as one I did years ago, but the Dragon Claw is worn on the knuckles and is meant to be some sort of bracer. I used to think it was a ring. The anatomy on the actual sprite looks kinda odd though to my eye, it kinda looks like Corvus' thumb is jutting out. Maybe it's just me though.

 

There's also a graphic within the Heretic IWAD literally named "LAME" and is a bit of text saying exactly that. Used for deathmatch on vanilla versions of the game i presume?

[Gez]

It's not actually used by the game; I didn't find any reference to it in the code. Grepping for "lame" only yielded results that talked about "flame".

The DOOM manuals call the partial invisibility, "Blur Artifacts".

It also uses the term "Visor" for the Light Goggles, although no one really uses that term. Also, the Green Armor and Blue Armor in the manual are respectively called the Security Armor and Combat Armor, which just about every Doom player these days simply say "Green Armor/Blue Armor" or "Armor/MegaArmor".

I didn't figure it out just now but I found it and I want to share it, there's the BOOMEDIT.wad that shows some useful stuff you can do in Boom here's the link https://www.doomworld.com/idgames/themes/TeamTNT/boom/boomedit

[Diabolución]

Two additional suggestions in the same vein, and their original source:

 

MBFEdit - mbfedit!.wad (Doom II) - WadArchive

hockey.wad (Doom II) - WadArchive

https://www.quaddicted.com/files/idgames/source/mbfsrc.zip

 

As for the difference between blue armour and green armour, this ZIP archive, by Len Pitre, includes a PWAD and two demos, which will show off the difference between them in regards of damage absorption.

The heat of Sevilla is already affecting me negatively, it seems.

you can use this to open the armor secret on map1 of doom 2 after you have lowered the zombies and lots of other useful things

 

theres a scythe 2 map that you can completely skip by using this sadly i dont remenber the name of it now and i am too lazy to look it up

[Sena]

Not exactly it, but I used to think that if there is a partial invisibility power up, then somewhere in the game there must be a complete invisibility

There is in Strife. :V

What decino said in one of his recent videos about clustered enemies causing splash damage to multiply against monsters because of some quirky behavior with the damage tables or whatever they're called. I thought that was pretty cool!

No idea about Scythe, but the first bugged release of TNT required this trick to finish MAP31.

[Scypek2]

Somehow I didn't realize that the sideways projectiles of the mancubus' third attack aren't angled as much as the angled projectiles of the first and second attack. Instead, the angle difference between the two shots remains constant, so the first two attacks have one straight projectile and one very angled projectile each, and the third attack has both projectiles angled, but only half as much.

 

I've read about the mancubus projectiles on the ZDoom wiki a few times, and it's mentioned there, but somehow my eyes glossed right over it. I only really realized after reading about it in the Dehacked hardcoding list.

This is more about Ultimate DOOM Builder than DOOM..

 

..in fact it is entirely about Ultimate DOOM Builder and not at all about DOOM..

 

..but I thought I'd share this because I don't want to keep it to myself.

 

I'm also not sure how much of a well known feature this is.. but..

 

Okay okay I'll get to it. Sheesh.

 

Random Things!

 

Spoiler

Say, you have some number of enemies:

 

If you highlight them and pick a category rather than a particular type..

 

 ..you get them randomized!

 

Okay. Maybe not that helpful.

 

Maybe if I tell you that it works with any "thing" category?

 

Still nothing?

 

But what if I told you that you can pick individual things (CTRL+Click on Windows, CMD+Click on Mac) in a list..

 

..and it'll randomize among just those types?

 

Slightly better, I thought, when I found out by playing around with it ^^

 

And of course it works with any type of thing, too..

 

..which is where it actually starts to become useful enough for me to actually use it some time, maybe xD

 

 

It's very likely documented somewhere but I found it by accident and thought maybe it's useful to someone.

 

I'll go back to URE2021 now ^^;

There are two transparent pixels in Doom II's city sky:


You'll notice that the pic seems fine if you fill these holes with color #255. Another proof (along with the alpha image formats) that the Id guys used this color as the transparent color in their image converter. When digitizing the source picture, this was probably the nearest palette color to what the source picture had there.

How did you find this out??

I just learned that the sky never changes in Doom 2 if you play continuously o.O

I think it was after trying various high-contrast background options for SLADE's image viewer. Not sure, though -- that was ten years ago!

[KubaloBlackMT]

I technically knew this one for some time, but Dis is a star shaped (Bastion) fort, at least in map design.

EDIT: I swear I had remembered seeing an image of a Star Shaped Fort that even had a bridge like  sorta thing, like the starting point to Dis. But I don't know for sure and it may just be false imagery, I didn't research it that much to be honest.

Oh.. I.. don't know ^^; I just like to give the shortcuts to functions "inclusively" if I know them.. and the alternative to the windows "multiselect" via CTRL on Mac would be CMD. 

 

Apologies for the misunderstanding.. or for spreading false hope. As far as I know there's no native port of UDB for Mac.

It's not a thing that I just found out but rather reminded of, that the Doom II manual refers to the super shotgun as the combat shotgun.

You don't want to walk into a firefight with your leisure shotgun.

[KubaloBlackMT]

I'm sure someone here mentioned it already but the manuals also called the Super Shotgun the "Combat Shotgun".

 

Who wrote the manuals?

 

is the Super Shotgun even its original name?

 

 my life is a lie

 

why is a Double Barreled Weapon a Combat Shotgun anyways?

 

What does the UAC fight against other than demons?

A couple of things during my Episode 1 rerun:

1. Zombiemen are slower than Shotgun Dudes. (Yes, this one took me 16 years.)

2. The switch which raises the bridge to the exit in E1M9 is "doubled" on the top via vertical tiling.

3. E1M6 has three backpacks in close proximity (though only one of them is non-secret) and the Computer Area Map isn't a secret in it.

Labor unions.

 

How do you think the UAC keep its workers in line despite the utter lack of OSHA safety measures, the frequent ritual sacrifices, and the constant demon invasion?

 

Why do you think they have the Space Marines on a speed dial?
