[Solved] Collision with an instance variable

Hello community,

I’m struggling a little with this concept (apologies)… perhaps it’s just me.

I have x4 sprites called “Wall” - joining to form a square

I have a sprite = “Bat”… which moves left to right.

I have watched GDevelop 7 - instance variables (more moving platforms) and above was my understanding of it - sorry.

I think I’ve got it now.
