It seems that sprite is not actually sprite in the normal sense in gideros? It is more like a hierarchical group as opposed to a visual animation
Sprite as far as I know, is an animated object that can be programmatically controlled such as, after input from texture packer
you can call something like sprite:play(), sprite:loop(), sprite:stop(), pause etc
and right now to animate things, it is rather manual because it calls enterframe? I am not sure how this would affect performance too, considering enterframe is almost always bad..
