Re: [Quake-C] droptofloor ()

[Cobalt <co...@te...>]

Came across another oddity on this function...if the ent is on a staircase 
and you call droptofloor (), it will place the ent's min_z on the surface of 
the step that I guess the tracelines in the engine pick as being the ground 
plane. So you can wind up with entities partially embedded into higher parts 
of the stairs.

One of my little projects is coming up with some qc that can detect stairs 
kind of reliably. I have done it using the players / clients physics, which 
was easier since its a MOVETYPE_WALK, but for other ents such as gibs and 
corpses, seems to pose a new challenge.
