Go ActionScript Animation Platform has just been released by the talented (and former Portland resident) Moses Gunesch. You may know Moses as the developer of FUSE, one of the first (and best) ActionScript 2 animation engines. Moses is back with a community-led animation platform initiative which has been in the works for some time.
"The Go ActionScript Animation Platform ("GOASAP") is a lightweight, portable set of generic base classes for buliding AS3 animation tools. Go provides structure and core functionality, but leaves the specifics to you.
"Go intends to support both linear (tweened) and physics animation, and could theoretically be extended to other base types, perhaps Collada animation for example. However at the time of this writing Go is at an early stage and the physics side is yet to be developed. Parallel and sequenced tweens are already supported by several optional utility classes: PlayableGroup, Sequence, and SequenceCA â€“ a sequence with "custom advance" options."
