Performance of frame animations

[Upsinn]

Hi,

any idea how I can improve performance of frame animations? I have a scene with about 100 small animations in loop (each having 20frames). I thought replace group of animations by one bigger, so for example instead of the original 100  50px*50px animations I had 4 250px*250px. Is it good idea?

Animation itself doesnt cost you anything. Are you using one file per all animations, one file per every animation or one file per frame?

Please explain it.

In my experience, 100 animations of 50x50 works good even on canvas renderer.

I have one file per one animation (20frames). In my scene are a lot of others things but in profile it looks like animations cost unnecessary amount of CPU, but maybe I do not understand CPU profile very well.

Ok, first - change frame of sprite is very cheap operation, so animation itself doesnt cost you anything. However, webgl optimization will work only if sequences of sprites you draw have the same base texture. I suggest to use shoebox (free) or texturepacker (paid) to compile all your frames into one atlas.
