I always get stuck infront of tree, rock, pillar etc, tried to use define pathpoint but it doesn't really help.

 

So help anyone who have script that avoid obtacles please post here, thanks  ;D

I dont think there is anyway to avoid them with scripts. It's implemented in walker to avoid them.

I haven't that problem, my L2W 1.79 IG always avoid obtacles, sometime they stuck into try but only 15 s. and it target another mob and go to it.
