Doom Oddities: "Difficulty Zero," IWAD Priority, and more!
Today we will look into the way the vanilla Doom engine sorts IWADs when more than one is found. Which one has top priority, and which one - lowest? We will find out through a real-time experiment.
We will also be looking into the Doom engine anomaly known as "Difficulty Zero," which is scarier and more despair-inducing than even Nightmare! itself. There will also be a few more funny glitches for you to see, and maybe even try out on your own, if you have the proper version of Doom.
Once again, the Doom engine will amaze us with its oddities and strange glitches. Enjoy!

Doom 3's Hidden Maps (20th Anniversary Special)

    Don't be so hard on yourself. Yes, the maps are bland with unnecessarily large rooms, and they certainly wouldn't pass for a quality playing experience, but they really aren't as horrible as you're making them out to be. When I first laid my hands on WadAuthor, I made stuff that was barely even functional, let alone enjoyable or just even aesthetically presentable. To give you an idea: I didn't even know what sectors were. I tried constructing rooms using impassable linedefs and middle textures all inside a giant square sector, and kept wondering why monster projectiles were going through everything. To add insult to injury, I had absolutely no crates outside.

    I wonder, does the super shotgun become available in Doom 1 through cheats if it is loaded through the Doom 2 executable? After all, the executable itself holds the game logic, while the IWAD only has the content like graphics, maps etc. My theory is that a silent, invisible super shotgun would be available. Any thoughts?

      AFAIK, there is no way to get the SSG as long as the game is running in "Doom 1 mode." There was a bit more peculiar behavior in the beta versions preceding the release of Doom 2 - in older versions, using IDKFA in Doom 1 and then trying to select the shotgun would immediately crash the game. In a later beta, they "fixed" this by making the shotgun unselectable after using the cheat.

    Why would Ravensoft create fully realized levels and make them inaccessible? These levels are fully put together with enemies, weapon placement, monster closets, keys, and working doors. It's even stranger when you consider the time frame Heretic released in... It was the dark ages for 3D gaming. They didn't have a quarter of the sweet tools they have now. Back in 1994, you couldn't even place an item in a map and check it out in game easily. You had to save your work, close out the WAD editor (map editor), open the game up, choose your new WAD, play/clip with God mode on, and then find your work. If the placement was wrong, repeat until you get it right (insanity).

When I get home from the gym I'm trying it! Addendum- The secret room that is only supposed to be reachable through multi-player only can actually be accessed in single player (without cheating). I don't know how I did it but I was able to gain access to it on several occasions in the Unity port on my Series X. In all my years of playing Doom 2 I have never tried multi-player once. So I know I didn't see it playing with others. Maybe when I get home I will start experimenting to see if I can open it. I want to say it has something to do with the 4 switches on the wall.

      It's like that meme "I was there, Gandalf, 3000 years ago..." Yeah, while my memory is a bit fuzzy, I think I first played Doom at some point in 1994 as well. It was the 1.0 shareware version and it was the most mind-blowing thing I had ever seen displayed on a monitor. I'm sure you know the feeling. ACtivating both the crusher and the rising floor works only in a modern source port, and it looks kinda awkward, like the ceiling is going through the floor. But it doesn't work in vanilla - once the crusher starts, the floor is stuck forever (even if you stop the crusher).

I was 13 years old, and I thought computers were the biggest wastes of time. Here are these big albatrosses that couldn't somehow play Super Mario/Sonic but cost over 10 times the cost of a console. I was heavily invested in Street Fighter II and competitive play. At the time, I had both the Sega Genesis/Sega CD and Snes. I was actually playing SF2SC on the Genesis when my dad walked in the front door with a new computer for work. My dad tried to get me to leave SF2SC for a few minutes to check out his new rig, but I wasn't interested. Until I heard what I thought was gun fire and screams. I paused my game, walked into the computer room, and.. Was struck dumb by what I saw. My dad was running around E1M2 Shareware Vanilla Doom with the pump shotgun blasting everything in sight. I thought... how was this possible? Am I dreaming? The game is in full 3d, and it was insanely fast. I saw a game with the best graphics, sounds, and gameplay I had ever witnessed. I wanted to play it right then and there. It was a tour de force of gaming that made everyone else before it seem pedestrian.

      No, the fact that a floor damages you relies on 2 things: 1. You are standing on the floor of the sector 2. The sector properties specify that it does damage The texture choices (floor/ceiling/walls) themselves do nothing, and if you are "in the ceiling" you are likely not standing either. If the ceiling looks like acid, but you don't take damage from standing in the sector, then the sector wasn't marked to damage you at all. The reason a floor damages you is entirely separate from how it looks, it's just usually a convention that the nukage floor texture is used with a specific sector type to do it's damage effect while you stand there, and others like lava use a similar but different sector type that does more damage each time it procs. Some maps / campaigns don't follow this convention so it's sometimes unclear if blood pools, or dirty water hurts you, and it can even be different for different maps, or even different uses of the same texture in the same map; inconsistencies like this are either a mistake or intentional cruelty on the part of the mapper. There are notable exceptions, such as in E2M1 of Doom there is a doorway shaped like a cross that does damage while you stand within it, but has a normal floor texture, and in E2M5 there is a sector in front of a wall with a Arch-vile carving that also does damage if you stand on the otherwise normal looking floor in front of it. There is also a version of the damaging floor type that causes the sector light level to pulse, which is at least a clue that something is wrong, such as in E2M7. If the mapper wanted to, they can make a map where it's only safe to walk on lava/nukage/acid/boiling blood, and the regular floor hurts you. The only real limitation is that only one sector type can be used at a time in Vanilla Doom, so you can't have most the normal flickering lights, secrets, or the timed sector open/closing logic on a floor that also damages the player. BOOM compatible maps (and later formats) allow arbitrary mixing of the sector type options. A tricky map could use the ceiling texture to indicate damage instead, such as open-sky being a hazard (maybe you are a vampire?). In E2M2 (Containment Area) there is a secret bridge across a damaging blood pool that is revealed by looking at the ceiling.

    7:00 no, I'M Dynamite. Also, kinda surprised you can even PLAY difficulty 0. Normally ALL entities/things/actors use difficulty flags, even DooMGuy himself. I'm genuinely curious, which difficulty does it look up for the DooMGuy? Also, what would happen if you tried to save/load during Difficulty 0?

    I still remember it clearly. Was addicted to PSX doom, watched my mom play it, and played with her when I was 4 years old, at least that's the earliest memory I have. Then when I was 7 years old, we went to a store that sold toys/games, and I saw "Doom Collector's Edition" just standing there, I begged her to buy it, and of course.. She did. Came home, and on the VERY old WinXP PC we had, I installed it and it came with Doom95. Some of the best memories of my life came from playing Doom95, I soon found out you could download WADs that were custom levels/sounds/graphics, AND I discovered source ports and online multiplayer because of it as well. That simple Collector's Edition box changed my life forever.

    I must ask you a question, Alexei; how do you feel about the canonocity of Doom 1 episodes such as "No Rest For The Living", "Sigil" and "Sigil 2"? I personally believe they are canon. First, you cram all of episode 4 in between the point where you kill the Spider Mastermind in Ep 3 and the Ep 3 end cinematic. Doomguy, getting the "message" from the demons, returns to Hell to avenge Daisy. While in Hell (No Rest For The Living), he learns of a sinister plot, leading to the Sigils. *Then* he returns to Earth in time for "Doom 2". What do you think?

    • @AlexeiVoronin
      @AlexeiVoronin 22 дня назад

      Hmmm, well, I don't usually concern myself with "canonicity" - I like to think that the Doom series doesn't have some super-strict established canon. It feels more inclusive this way. I also don't think the loss of his fellow marines before the beginning of Doom 1 is the main reason Doomguy hates the demons so much... even though losing a pet is quite traumatic.

    12:31 - about the inaccessable room (in Doom 2 - Map 07), that room is there for deathmatchers, so they can end the level when they're done fragging each other. I've know about this room for awhile because I watch a lot of Doom and Doom 2 demo lumps. Some of my favorites take place in Map 07.

    I wonder what the code responsible for the "difficulty zero bug" looks like. It looks like a sensible behavior, something planned by the devs, to avoid crashing. At the start of the video, my guess was : no monster mode is the 0-difficulty, but saldly no... It would have been even more sensible than the actual behavior.

      I remember at least one of the Commander Keen games had faulty code that allowed you to enter something like difficulty 0 (or "Super Easy" mode), though it is practically identical to Easy (difficulty 1).

    • @DidyzZ666
      @DidyzZ666 21 день назад

      It's not really anything planned by the devs really, entities in doom maps are called 'things' in editors and they come with a flag value to tell things like in which difficulty do they appear. Is it multiplayer only? if it's a monster, is it in ambush mode (doesn't react to sound, only wake up on seeing the player or being hurt.) Internally, for placing things in a level, there are 3 difficulties, Easy with a value of 1, Medium with a value of 2, and Hard with a value of 4. Furthermore, Ambush has a value of 8, multiplayer only a value of 16. So, for example, for a thing to appear in all difficulties but to not be in ambush or multiplayer only, you give it a flag value of 7, adding the values of each difficulties together. Skill 0 has no defined difficulty value, it's neither easy, medium or hard, therefore nothing is enabled in the map. The only exception to this are the player starts, as they always works and don't take into account their flag value, enabling us to play on skill 0 with crashing.
