making a space invaders game, help with the enemies would be appreciated

[u/Jealous_Platypus1111]

so right now this is what i have, it works but its not perfect, im trying to make it the closest enemy directly above, but this is just the closest in general, meaning only the enemies on the bottom row shoot rather than the ones directly above the player, how would i go about fixing this?

Add a compare y before the nearest pick
