Thought Will Rise

Here is an example of using Fuse to do a code based Bezier tween.

And here is the code:

=============================================================================
EXPLANATION:
Load in the Fuse classes.
Register Penner’s easing equations.
Draw a box on the stage.
Create some start and stop buttons.
The tween gets constructed (bezierTweenBox)when the start button is pushed.
Create a fuse instance (this.bezier).
Add the control points and the finish x and y.
Add another tween.
This creates an “s” pattern.
