Animations are recreated in real-time using the sprite piece images just like in Spriter.

Manipulate animations via game events.
Reuse your animation data for completely new characters or character customizations.
Saves a lot of memory your game would otherwise take up with spritesheets.

Animations can be exported as spritesheets, animated GIF files, sequential images and more.

Spawn bullets, particle effects, or anything that requires precise locations and angles.
