Well that is what i want, but the only problem is that it won't work...

The player is supposed to climb walls when you press ctrl, and it works
great on block, but in the terrain when you press ctrl he tryed to climb,
it seems he believes it to be a wall, the player just walks over a tent
as if it had no height...

And in the block next to the tent everything works perfect..

Here is a demo and you'll see what i mean:
