Sorry, I'm not sure if i understand what you mean?
I made a .capx that shows what i wan't to achieve.
But I want to achieve the same thing without using the "EdgeBlocker" sprite.
Because I fear that the EdgeBlocker sprites can have a performance hit when the levels get bigger.
If this isn't possible without using the EdgeBlocker sprite I'll do it with them.
btw it's super fun to play around with this addon
