Okay, first off, i know title doesnt explain really well, but I'm having this problem. I tried a sprite with the pathfinding behaviour, so when you click on it, you choose somewhere in the map with the mouse, and the sprite moves there. It was all working good in a blank project sheet, but as soon as i put obstacles in (with solid behaviour), the pathfinding sprite won't move. Whenever I tell it to go like, 10 feet in front of it, it works, but when i tell it to go at the other side of a wall, it stops working.
I know i dont explain very well, but i hope you understand "^^
Trying to fix pathfinding problems from just an explanation is nearly impossible - there are just too many things that could be wrong, e.g. cell size.
It would make it much quicker if you provide a .capx which highlights your problem.
BTW does the built-in pathfinding examples work correctly for you? If so, you may be able to see where you have gone wrong.
