[TF2] Sticking to an angled wall will randomly trigger a collision and nullify movement (a.k.a. wallbug / wall bug)

[ldesgoui]

Hello,

Angled walls (read: that don't follow the lines of the 3d world grid) will sometimes trigger collisions and nullify movement, sometimes for a short moment, sometimes for longer. Supposedly caused by floating point approximation. No fall damage is applied, no matter how high the jump was. Forcing ::GetTickInterval() to return 0.0001 raises the randomness factor to practically one, and might even allow for wallbugs on straight walls (not sure).

Thanks
