[quote="YetAnotherSuperhero":2unxdxme]I'm loading external graphics so my game can be moddable. So that means each image has to go into a animation frame for the sprite. Now instead of have 100 frames when I might only need 10, is there a way to add a frame while the game is running, so memory is saved?[/quote:2unxdxme]
I do believe there's no way to add new animation frames at runtime. So you might need to become very creative in order to include moddable animations. Or just force a frame count restriction on the user.
