StageXL - Flump runtime

Flump converts Flash keyframe animations into texture atlases and JSON that can easily be used with the StageXL library. The advantage over sprite sheet animations is the much smaller download size and memory consumption. The demo below shows the texture atlas generated by Flump and four different character animations built with Flash Professional.

  resourceManager.load()
    .then((_) => stage.addChild(new FlumpDemo()))
    .catchError((e) => print(e));
}
