well apparently as i see, in hl2 there is no func_ladder entity.
i also found out that there is a 'ladder' brush but i have a problem.
when i pu the ladder brush near my real ladder just like i did in hl1 with the aaatrigger and everything seems fine, also the properties said that its a 'ladder'
But the problem is that when i get in the game, that apears as an normal invisible brush. i cant climb it and the brush doesnt do anything a ladder should. any help?
