The more you teach us about Doom's inner workings, the more I'm convinced that the game is a concatenation of horrifying programming mistakes that somehow exploded at the same time until all worked mostly perfectly.

Tbf the same thing could be said about most early PC and console games. Bc of all the hardware limitations, most were just a giant tangled mess of hacked code that only breaks if you don't look at it wrong. The main talent of past devs were just trying to make sure that it only exploded in conditions that people wouldn't likely be in, lol

Great video as always! Regarding the blockmap-bug, is it present in all source ports? Is it technically possible to write an improved version of the collision check running on today's computers, or will it break something else in the engine?

[@decino]

GZDoom fixes it.

[@DinnerForkTongue]

The ZDoom+ family (ZDoom and all derived source ports, including Skulltag and Zandronum) fixes the blockmap bug.

[@Shepardus]

If you want to preserve demo compatibility, you have to keep the existing blockmap behavior (along with all other behaviors). If that's not a concern, however, there are plenty of ways to fix the blockmap bug. Coincident explains some ways in his video on the blockmap bug. The ZDoom family of ports fix the bug, as do some other ports such as Doom Retro.

[@EsoiTheGrumpyMawile]

Funnily enough, the fix to collision code improves the mastermind a lot, she does not get sutck all the time and her hitscan attacks hit more reliably, she actually beats the cyberdemon on map20 a lot more often in zdoom

What's great about Doom info is, if you just want to read about it, a lot of these are on the Wiki. Though not usually with code details or examples. That, and, the more esoteric ones that decino's covered aren't even on the Wiki I think (or, at the respective time of video release). Both together? A great combo.

[@Ben_of_Langley]

I think my favourite parts to this video was the two cyber demon bits at 3:31 & 5:29 and my most favourite part was the 6:00 but with the rocker just tapping the nose of the shorgunner and it blowing up like a nuke and those sound effects are just brilliant put a real smile on my face other than that very interesting stuff the demon being placed to close to a wall is understandable really but as for the rest I did wonder what was going on with that so with that as always cheers for upload decino.

[@rgerber]

The way enemies move in Doom is one of the best things about it, they always move in such an non predictable way that makes them seem stupid and messy but also rather dangerous what i love so much about it. In modern games it seems like enemies move in a rather linear way

This explains a lot about the enemy AI, another great analysis video. I would love to know how the Invisibility sphere works or more information on the Cast of Doom screen. Looking forward to your next one. Whatever the topic I'm sure it will be fascinating.🙂💛

[@mwperk02]

The invisibility sphere appears to work by offsetting attacks aimed at you. Including hitscan and projectiles not sure about melee attacks though. This can be both good and bad though as it means enemy attacks while less likely to hit you in places where your mobility is restricted such as a narrow hallway it also means it's much harder to predict where the attacks will be. Which is actually why I consider mancubi one of the hardest demons to fight as they have pre made offset in their attacks.
