Func ladder

When VBSP compiles the map, it converts func_ladder brushes into regular world brushes with ladder contents, and an info_ladder entity is created with KVs indicating the bounding box of the ladder.

Note:This entity has not been available since Source SDK 2006 and later and doesn't function in ep1-2 series, even if to added to base.fgd. Use Func_useableladder instead.
Func_ladder is still used in Left 4 Dead series, Counter-Strike: Source, Day of Defeat: Source, Garry's Mod, Vampire: The Masquerade – Bloodlines, and The Ship: Murder Party.

Important:This entity does not exist in CS:GO engine branch and Strata Source, and if used will delete the applied brush on spawn. Consult Creating Ladders (CSGO) for help.

Entity description

A ladder. Players will be able to freely move along this brush, as if it was a ladder. If you are using a model prop for the visual representation of the ladder in the map, apply the toolsinvisibleladder material to the func_ladder brush.

This entity has no keyvalues, flags, inputs, or outputs.

In code, it is represented by theCInfoLadderclass, defined in thenav_ladder.cppfile.

Note:This entity is prone to exploitation, as a player can travel up the ladder with two keys at once to travel faster up, and at the end of the ladder they will be flung upwards to possibly reach high areas.
