Summary

0000570: Various 3d Floor glitches

Description

NOTE: All of these effects were only tested online. The "monsters fall through 0 height 3d floors" bug only happens online.

- If you stand under 3d floor of any alpha or size (tested with 0 and 8) you can ghost through it if you hit moveup long enough. It works best near walls, and allegedly better while shooting. It happens with or without

unlagged. To test this, turn the fly cheat on, or summon a waterzone thing. It happens with both scenarios.

You can also go down through a 3d floor in water, or with the fly cheat. You cannot go down or up through 3d floors without the fly cheat or without water.

You can't jump through a 3d floor, the only way through it is to use the move up or move down control

-Monsters who are spawned on 0 height 3d floors, either translucent or opaque, will appear to fall through, their sprite will move between the levels, possibly when a state change happens (monsters will finish their attacks).
This happens in both software and opengl, and it happens whether they were placed there in the map or spawned later on. Monsters spawned on 3d floors with a height of 8 do not have their sprites fall through.

Powerups, and decoration will have the same problem.

It should also be noted that when clients reconnect, the sprites change randomly from under to over these 0 height 3d floors. When they fall through, they either appear on the floor of the (non zero height) 3d floor or
real floor below them, or on top of another enemy/object if they "fall" on something.

How to test:

1. start the game with the testing PWAD
2. put notarget on
3. feel around on the top level for invisible blocking spots in the map. If you open up the map in doombuilder, you will notice that these spots correlate to the position of actors placed on the top level in the map.
4. turn notarget off, and summon a demon on the top level. It will appear to skip between 3d floor levels, but it really always on the top level.

- You can always hit players with the BFG through zero height translucent 3d floors. You can always hit players with the chainsaw through any zero height 3d floor

- Autoaim occasionally tries to aim at players through zero height 3d floors.

- Teleporters are glitchy on 0 height 3d floors.

Note: In the sample wad, the texture with the tiny gray squares behind the blue/red texture will teleport you to the same place but with teleport (no stop).

If you do a teleport, no stop, to a teleport thing on the floor of a 0 height translucent 3d floor, you will be above it. If you do a normal teleport to it, you will fall through the floor (blue teleporter on the left)

If you do any teleport to the middle of a zero height 3d floor, you will appear on the floor below it, instantly, without falling (red teleporter in sample wad)

Teleports to non-zero height 3d floors work as expected (blue teleporter on the right)
