I am making a slenderman game in unity pro 4. Everything works fine except from 2. The follow script and the tree colliders.
1)The player won’t collide with trees. Tree colliders are on. Don’t know how to fix that:(
2)The script to make him follow is a bit buggy. Works good, but instead of stay, he flies in the air a meter from the ground in horizontal position. I don’t know exactly where the problem is. Hope you help me:/
Here is it:
