How do I make a code valid for only 1 object?

I make a wall and add to the wall solid I just want it to be valid for sprite1 not for sprite2 (and other objects).

The sprite1 can't get through the wall, but the sprite 2 does.

Thank you!

one way to do it quick and dirty would be to disable the collision of one of the sprite...

The clean way would be to use the collision filter.

its in the MISC section of your sprite when you add an action inside your project

Thank you!
