How do I make this player not go through this rock?

So I created a movement system for this guy, but he will always pass through my obstacles.

I will show you pictures of what I mean

Is there any way I can make the rock impassible?

Give the rocks a solid behavior.

I have, but it did nothing.

Make sure the behavior is enabled, it should be working. I just tested it to make sure and its still working by default. You may be overriding it somehow. Post a pic of your code or a capx link if you like.

You can use "Is overlapping at offset", inverted, to see if the position you are about to move into will not overlap.

Here are the images

thanks, helps a lot
