[Behavior] SplinePath

It's a behavior which was getting dusty on my hard drive, so I cleaned it a bit, and I'm posting it here.

The idea is to set Spline Path for Sprite, making them moves along a spline with a smooth path.



The spline code is adapted from here : https://github.com/MmmCurry/jquery.crSpline. Instead of setting the (X,Y) position via CSS and jQuery.fx, I'm directly accessing the (X,Y) position of the Sprite.

The spline used is Catmull-Rom, allowing the trajectory to go through the points, instead of Bezier, where the control points and the trajectory points are different.

The demo : http://dl.dropbox.com/u/1412774/SplinePathBehavior/index.html

The plugin : http://dl.dropbox.com/u/1412774/SplinePathBehavior/pode_splinepath.0.1.zip

Edit : the demo uses R0j0hound's Canvas, for the trail.

@newt : yes, I'm planning to add speed (allowing you to choose how much time between two points), and resetting the behavior.

@tonycrew : for the moment, you need to do that manually, by adding points for the "go-back" path, but thanks for the suggestion, I'm going to add it.

very useful...tnx a lot Pode
