The proof gameplay is 2D only is that it could be play from start to finish using only a 2D map areal view (while in Doom for example it would be another story). There is no floor/ceiling elevation, no stairs, no pit, nothing moving along the Z axis (eg : missiles in Doom).

After seeing AutoDOOM working, I have to say I'm really impressed ! Good job. I have also tried to wrote a DOOM BOT some years ago (based on Chocolate Doom port) but give up after a while because of the difficulty and lack of motivation. I went to the point the bot could shoot enemies, auto open doors and switches in front of him and avoid shooting barrels (something very important if you don't wanna die quickly). Anyway, I struggled for the pathfinding part. I tried many things like rasterizing all sectors into a 2D grid and building a quadtree out of it. Eventually I came to conclusion what would be the best would be to generate a navmesh from of the map (this is what you did with AutoDOOM/GLBSP if i am not mistaken). What is impressive with AutoDOOM is how it can shoot and move at the same time, dodge enemies, etc... It also seems to never get stuck (although i'm sure it will on some very HARD maps which involve running over platforms and such). Also (just for info) before trying to wrote a DOOM BOT I also wrote one for Wolf3D (which is something LOT of times easier): https://github.com/tigrouind/wolfenstein-3D-bot You can view it in action here: youtube Unlike some bots, it do not try to kill everybody or collect everything, but to finish the level as fast as possible. I didn't know about AutoWolf until now.

What is the heaviest and most complex DOOM map you have ever play ? By "heavy" I mean a map with a complex architecture, with tons of sectors transparency and whatever, that literally put the engine on his knees. This is something different from this thread where by area/size is important. Slowest I have found so far are in Sunder wad, MAP09 and MAP10. On my machine, ZDoom barely plays them at 20fps. (While GZDoom have no problem running them correctly). They are certainly not the biggest maps out there but i'm not a wad specialist.

Thanks both you guys. "3D floors", this is the name. It seems they even implemented slopes. I'm impressed to discover how far it things have been pushed.

Hi there, I was playing City Assault map from Sergeant_Mark_IV lately (which is by the way an excellent map), and one thing amaze me. This is at the end of the level. Here : You have basically two floors at the same place (and no glitches). It does not seems to be sprites. How is it possible ? AFAIK, this is one of the biggest limitation of the DOOM engine. I know that gzdoom/zdoom (that i use) isn't actually the exact DOOM engine (like Chocolate), but rather an improvement. Is it something like room over room feature like in Build engine ?
