Hello again, for my game i need to make a battle system similar to pokemon. Basically i need an array with sprites, and then store information using sprite data. After i do that i create a sprite from the array randomly and use the correct information for it.

I found a way to do this, but the problem is… it’s really inefficient and not scalable.

I’m not entirely sure how to do this system properly so any advice helps a lot!
