How do I stop a sprite clipping into another when pathfindin

I have tried making the sprite go round the rocks to reach the tree:

But the sprite just goes through parts of the rocks , even when i set them as solid, which is why i tried to use the physics to push the sprite away, but it didnt work:

Please help!

*bump*

I get that too sometimes and the way I worked around it is by making the path finding object a bit smaller and changing the collision polygon of both objects "pathfinder and obstacle".. Might work, but not something I really worked out completely.
