I’ve just released GTween beta 5. As I previously mentioned, this release is a significant rewrite to the full tweening engine. It stabilizes much of the positioning logic, and makes it more predictable. It also involved some very significant changes to the API, and the introduction of two important new classes: GTweenTimeline, and GTweeny.
GTween specific enhancements include a reduction in size to 4.5kb, a more predictable positioning model, slightly enhanced performance, the ability to specify repeat counts, full read/write access to start and end property values, the ability to lock starting properties, and a clean up of the API and code.
To read more about GTween, check out some demos, or download the library, visit gskinner.com/libraries/gtween/. To get more information on what’s changed, check out the version history or the API documentation.
This was a major rewrite, which pretty much guarantees that it has introduced new bugs. Please feel free to provide bug reports and feedback in the comments below. I’m hoping the next release will be final, once this version has seen some testing, bug fixing, and revisions based on feedback.
Here’s a super simple demo, showing GTween’s ability to deal with interrupted tweens. When you click around, it simply sets new end properties on each tween, and the tween adapts to the new values (and hey, it looks kind of cool). Check out the home page for more complex demos.
