You can make anything into a ladder. even something slippery like
a plastic fish.
if you want to make one of the ladders you see if hl, often that
damn red one, select the ladder, and make a ladder, but how you
ask, well once you have your ladder ready and waiting.
sure its not really thick as it will look silly, (bit like me)
now select the aaa texture and put it over your ladder, so you
can see the aaa texture in front of your ladder, the same height
and width, a mirror of it, now select the aaa texture (pink with
a's on), make sure its not massively thick please. and make it
into a func_squirrel, no wait a func_ladder, and then you have
it. go test your squirrel, er I mean ladder, and adjust it as
you see fit.
a brush with the ladder texture on it, a few units thick. then
align your ladder texture on it well.(make this brush a func_wall
or func_illusionary and set render mode solid,fx amount 255)
>Produce a block with the aaa texture on it and place it where
you want the player to climb, in most cases on the front of the
ladder, like a sandwich, with the aaa texture on top or in front,
ok like some toast then.

>Test your ladder and wash some windows
