I’m working on a arcadey space shooter game and I’ve got the basic outline of it done but, on double enemy spawns there will be one enemy that is invincible and transfers its damage to the other.  
How can I fix this? Thanks

Thanks, although, I don’t quite know how to use that extension lol, may I ask how would I apply it for my game?

Wait,  
I see your problem

You see, the Variable block will update to the latest sprite created with that variable, so it will destroy the most recent created enemy instead.  
Here’s how to fix it:

“OtherSprite” is referring to the Enemy the projectile collided with, so it will destroy the correct one instead.
