func_ladder is an internal brush entity available in all 
Source games.
Differences
Before 
Left 4 Dead
When VBSP compiles the map, it converts func_ladder brushes into regular world brushes with added ladder contents, and an info_ladder entity is created with KVs indicating the bounding box of the ladder.
Because this type of info_ladder exists only in 
Source 2006 and 
Source 2007, this entity is obsolete.
Since Left 4 Dead
VBSP converts this to func_simpleladder which has its keyvalues set based on %CompileTeam and which side of the brush has a ladder texture. The brush contents are NOT altered and depend on %CompileLadder flag. The func_simpleladder entity only exists in 
Left 4 Dead series, so this entity should not be used in first party titles outside of those games.
Usage
- Left 4 Dead series - Use this. See L4D_Level_Design/Ladders. Can also use func_brush if toggling it is neccessary but will be climbable from any side.
Half-Life 2 series, 
Portal Players or NPCs are unable to use ladder contents for climbing. Use func_useableladder instead.
Team Fortress 2, 
Portal 2, 
Alien Swarm[confirm] - climbing not possible. Needs workarounds Working_ladders#Brush-based_ladder_workaround- anything else - use func_detail (or func_brush if toggling is wanted) with a
tools/toolsinvisbleladdertexture (or other that has %CompileLadder).
Note:Non style climbing 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.FGD Code
As this entity is nonfunctional in post- games, and vanilla Left 4 Dead series FGDs include a func_ladder entry, this entry reflects pre- games.
<syntaxhighlight lang=js>
@SolidClass = func_ladder : "Brush ladder. Players will be able to freely along this brush, as if it was a ladder.\n\nIf you are using toolsinvisibleladder or any other material with %CompileLadder, use func_detail instead, especially if it does not have %CompileDetail as well."
