What we don't know about Doom

Due to doubts of east/north linedef skips I'm going to post the testwad I was using for linedef skip testing and a demo where the skip fails northward in a situation in which it would pass in the south or west directions.

Isn't the reason pretty obvious? When the player is traveling north or east at a speed greater than 15 units / tic, the movement gets split into 2 parts and P_TryMove (and therefore PIT_CheckLine) is called for each half-step.

Anyways, this sort of thing is why I am researching it to write up a big post that goes through the movement code and explains how everything happens: straferunning, wallrunning, thingrunning, door trick, item bumps, bar glides, linedef skips, void glides, etc.

As a big fan of advanced movement in FPS games, particularly id's, this is going to be of great interest.

Yep, can't wait!

Well, I've always wondered if the mancubus lost his real arms due to diabetic complications and had them replaced with rockets to compensate for his uselessness as a brawler since he had no arms.

[Li'l devil]

Well, I've been wondering why lost-soul's sprite was change in v1.666 (or v1.5, I don't remember).

What are you talking about?

We don't know why the Doomguy only punches with one hand.

Doom Wiki said:

The sprite graphics for the lost soul were revised between v1.2 and Doom II, with significant changes to the structure of the skull, particularly around the eyes. According to John Romero, these changes were made by Adrian Carmack for purely aesthetic reasons.[1] Ports based on the Atari Jaguar version retained the older sprites, up to and including the Sony PlayStation games. The older graphics also continue to be displayed on modern versions of the Doom II retail packaging's reverse panel.

Also, look through this thread, you'll find the picture regarding the change eventually:

Yes you can. I think your table is correct except the wallrun values should be doubled. 60, not 30. 84, not 42.

Indeed, the only ones I could not test in extreme conditions was wallrunning at an angle and combining SR50 with any kind of wallrun. I remember that a simple S-N wallrunning (e.g. in MAP01) yielded "only" 30, though, while propelling myself with a rocket against a wall produced "only" a 42 mu/tic spike.

Perhaps there isn't a single wallrunning speed, but it's heavily dependent on orientation and kind of input (regular, SR40, SR50 etc.).

So perhaps the most correct statement would be "Maximum player thrust can not exceed 30 mu per tic, per axis, and per input axis"? This would take into account the extra thrust that trickery like SR50 achieves, essentially doubling the calls to P_XYMovement in a tic, and would explain why the doubled values 60 vs 30, 84 vs 42 etc.

However, by using plain "vanilla" controls (no SR50, no "double thrusting" trickery), one would indeed not be able to exceed 30 and 42 (at a pure x/y direction and a perfect 45 degree slope and multiples, accordingly).

Wouldn't that be because he's got only a single knuckleduster?

This is especially confusing to me because he appears to be ambidextrous. Sometimes I wish I was born left handed because the world is designed for righties, so lefties pretty much have to develop at least some coordination with their non-dominant hand. I'm right-handed, and the world is designed for me, so I'm a fucking klutz and cripple with my left hand because I never have to use it for anything.

[Olroda]

Well, my right hand is my dominant hand, but when I was training Kendo (japanese fencing) I was taught to use my left instead, and that went well. I think it's actually more a matter of dedication and training than "being" ambidextrous, right or left handed (not that you implied otherwise, Face23785). Perhaps Our Hero is punching with his left because it's quicker for him to switch to his guns with his right.

Well, now we know what Brutal Doom needs next: a complete Boxing and martial arts assortment of moves, with multiple, varied punches and combos, and also the ability for Doomguy to BLOCK monster attacks with his hands, ducking, footwork etc., turning Doom into a "first person brawler" game, too.

I agree, that's pretty much the same thing I was getting at. I have no incentive to use my left hand, so it's useless. If I made a point to use it more, I'm sure it can be learned. I thought something similar about the guns too, perhaps when you switch to your fist, he's actually still holding his gun in his right hand, that's how you can switch weapons so fast! Of course this falls apart if you switch to a different weapon than you had before you brought up the fist, but who's counting?

Go to the game now, switch to the fist, but don't press the fire button. When the idle hand comes up, note which hand it is.

[VGamingJunkie]

He obviously puts his gun into his convenient wormhole dimension pocket that many protagonists (Link) seem to have.

Maybe not the the fists, but notice how Doomguy holds the pistol left handed, but all other weapons right handed. He's holding on to the shotgun handle most of the time with his right hand while shooting the pistol with his left. And because he trained with handguns in this manner, Doomguy will still use it lefthandedly even when its the only firearm on him.

How is Doomguy able to rip and tear so easily, are the monsters made of marshmallow?

If you mean with his fist, I'd guess because he's a trained marine. Also, I don't know what the hell's in Berserk Packs but I'm pretty sure it would get you disqualified at any sporting event.

It is a concentrated mixture of PCP and Steroids.


Probably a bit of Meth in there, too.

[VGamingJunkie]

Probably a good amount of adrenaline or something, too, since it brings your health up to 100.

[Tracer]

Why does Doomguy's armor look so different from the former humans'?

[VGamingJunkie]

Because lower ranking. They seem to just be grunts with sargents and commandos respectively. Doom Guy is a trained marine, he's going to have slightly different armor than essentially guards. What I'd like to know is why Former Humans are rocking punk green hair.

The marine doesn't always wear green armor, also blue armor. And you can change it's color in some ports.
I think he wears different kind of armor because he belongs to different kind of armed forces. Zombies are probably just former security guards, while the marine is probably a space paratrooper, or something like that.

Zombiemans have green hair, because they were dipped into the slime. (that's how they got zombified)

[VGamingJunkie]

Could have sworn they were just demonically possessed like in Doom 3 and aren't literal zombies, just meat puppets being controlled by evil spirits. If they were zombies as we know them, they wouldn't be intelligent enough to use guns, they'd just shamble and try to melee you. Granted, there are possessed humans in Doom 3 that do that. XD

[Li'l devil]

I also noticed one interesting thing, which I can't explain: when doomguy's health is about 40-60%, his face features what looks like green paint under his eyes.

[VGamingJunkie]

I think that's supposed to be bruising, it's hard to tell because of the limited palette at the time. This HD interpretation sort of looks like he's got some black eye going on.

[Danfun64]

You know, there's something this image has that the original lacks...

uncanny valley...

bleh!

[Avoozl]

I honestly don't like how they look.
