How do I create top down walls and pillars?

I am trying to add pillars and walls to a top down game, when i add the solid behavior to the pillars, my character cannot move through them but other objects still can. "Solid: Make the object impassable, so other object cannot move or fall through it". Not sure what I am missing, appreciate any advice

Your other objects do not contain a behavior that interacts with the solid behavior.

Add something like a 8-direction behavior to them and you will see them not go through solid anymore.

Be sure to uncheck "Default controls" for them.

Thanks!
