Ladders
Most Source games feature some mechanism that allows players to climb and descend from ladders.
To do: Figure out which games need to use nav_build_ladder
for bot navigation purposes.
Left 4 Dead series, Day of Defeat: Source, and Counter-Strike: Source[edit | edit source]
Use func_ladder
.
Half-Life 2 series and Portal[edit | edit source]
Use func_useableladder
.
Counter-Strike: Global Offensive[edit | edit source]
Make a regular brush and texture at least one side with tools/toolsinvisibleladder
.
Tip: Cover sides which shouldn't be climbable with tools/toolsplayerclip
.
Tip: This brush will cut visleaves, oddly, so it's good practice to make it a func_detail
. The ladder can also be enabled or disabled by making it a func_brush
.
Portal 2, Alien Swarm and Team Fortress 2[edit | edit source]
Ladders cannot be created for these games. Alien Swarm's code is publicly available, so ladder functionality could be added. One potential workaround is creating a very thin and tall staircase of clip brushes.
