func_useableladder is a point entity available in all Source games.

Class hierarchy
CFuncLadder ↳CBaseEntity
func_ladder.cpp

It is a Half-Life 2-style ladder. Handles player auto mount/unmount, as well as +use to get onto the ladder.

Note:This entity is non-functional in Counter-Strike: Source and Left 4 Dead series. Use func_ladder instead.

Bug:There seems to be a bug where mounting or dismounting a ladder within a trigger volume will cause the trigger to fire outputs as if the player left and re-entered the volume. Seems to be because of how dismounting works, as it technically gives the player noclip temporarily, which makes the player not touch the trigger.  [todo tested in ?]

Issues

You should be sure, that ladder is not in contact with your brush if using it for ladder representation, otherwise it won't work.

Usable ladder has a gap between itself and brush.
