Question

I just started with animated sprites and added one but it seems to not work, any help would be appreciated.

It just shows the sprite as a black box.The background shows up though. I have found that if i didn’t used (bi~).load(); it would show as a black box but it has a load();.

Looks like there is not enough space on atlas for your sprite texture. Try to increase your atlas size so it is bigger or equal to your sprite size + padding.
