How do I make this skull head moving?

I want the skull to move foward when the path of rotating asteroids is open.

Currently I use pathfinding behavior. But it seems pathfinding only works when since the beginning there are no obstacles. So in this case, if the path is opening and closing, what should I do to make the skull moving?

Hi,

You can regenerate obstacle map and wait 0.1s before making your skull to find a path.

Your asteroids need to have solid behaviour by the way.

Ok, now the skull is moving. The asteroid is solid. But the skull can move through the asteroid.

Hmmm... Maybe I have to make a different calculation for this path.

Calculate path, checks where all the solid objects are (those where it can not move) if your solid objects move around, after calculating path, then its effect is lost, as the solid objects would be out of place.
