Player falling through map (brushwork)

traceline isn't enough.
ideally use tracebox instead, then you know you won't enter inside the player.
if your engine of choice is shit, then you can use droptofloor instead, and revert the teleport on failure.

Also, try adding '0 0 1' to the destination origin. It may help.

I'm wondering about other.owner.origin... I can't tell from this code, but perhaps you want other.origin?

[Spike]

other.origin + trace_endpos
and that. that's a wtf too.
