My brother is making a Scratch project that is a zombie shooter where you can't just stand still, so instead of zombies spawning on the edge, he made it so they spawn randomly, but can't touch the players Safezone, directly moving the same as the player. For some reason, the zombie sprite that spawns the clone won't obey this code. Is there any way to fix this?

Zombie Shooter

I think it's because hidden sprites can't detect if they're touching anything

when I receive [game start v] :: cat
+set [ghost v] effect to (100)
+show
forever
...
end
