Summary

0001801: compat_plasmabump breaks collision physics

Description

compat_plasmabump 1 will result in some weird behavior with zandronum's physics.
Having a high enough speed will make you pass through walls and using the fly command will be extremly odd and sometimes hard to control: your velocity somehow never slow down as if you were in space.
While testing on zdaemon none of this happens.

Steps To Reproduce

In zdaemon:
zdaemon have wallrunning on at all times however "classic wall running" in the gameplay options seems to enable the plasma bump bug. You can try it for yourself. Once you can reproduce the plasma bump bug in zdaemon do:
-Fly in console
-Move around
OR:
-Go in doom2's map01 exit room
-Face a wall
-Summon 20 rockets at the same time

In zandronum:
zandronum doesn't have wall running on by default and turning it on won't change anything. The wall running flag behaves as it should. To enable the plasma bump bug type compat_plasmabump 1 in console and then:
-fly in console and then move around
OR:
-Go in doom2's map01 exit room
-Face a wall
-compat_explosionthrust 1 in console to simulate zdaemon's rockets
-Summon 20 rockets at the same time
-Watch as you pass through a wall

Notes
(0008775) Leonard (developer) 2014-05-11 12:13	Zandronum 2.0 behaves the same.

(0008783) Dusk (developer) 2014-05-11 20:29	With the wallrun flag on you are re-enabling buggy movement physics. Wallrunning is the result of a bug and what you are experiencing is a side effect.
