Tweener: Bezier Curve Animations

Lets say you want to use Tweener to animate a camera in your PV3D Scene from z:0 to z:1400... but you want it to animate along a path with smooth bezier curves. Piece of cake! Here is how you do it.

Example (don't freak, there's a lot more comments than there is code):
//first you will need to import your Tweener classes
//in this case, also import the CurveModifiers class
import caurina.transitions.Tweener;
import caurina.transitions.properties.CurveModifiers;

//instantiate the CurveModifiers
CurveModifiers.init();

//create an Array that will hold the various bezier curve points
//the values indicate the that camera will swing from the left to the right
var curvePath:Array = new Array();
curvePath.push({x:400});
curvePath.push({x:-400});
curvePath.push({x:400});
curvePath.push({x:-400});
//you could also add in additional bezier curve point paramerts
//such as curvePath.push({x:400, y:200, z:200});

//set up a function to set the default position of the camera
//and to instantiate a tweener animation
//note that there is an additional parameter "_bezier" in the Tweener parameters
//in the "_bezier" parameter we passed in our curvePath array
function startTween():void
{
camera.z = -200;
Tweener.addTween(camera, {
x:0,
z:1400,
_bezier:curvePath,
time:12,
transition:"linear",
onComplete:startTween});
}

//lastly, call the startTween function to fire it off
//since the Tweener function has an onComplete parameter
//of startTween the animation will loop continuously
startTween();
