Motion guided tweens

Tweensy has a package called guides which allow for defining a direction, orbit or bezier path to be used on a motion tween.

Direction guided tweens

A direction guide has a direction and a distance. Tweening the position on the Direction2D class defines where on the path the item is placed initially the path is at position 0 and ends at position 1.

import com.flashdynamix.motion.;
 import com.flashdynamix.motion.guides.Direction2D;
 
var tween:TweensyGroup = new TweensyGroup();
 tween.to(new Direction2D(myInstance, 45, 100), {position:1});

This will animate 'myInstance' a distance of 100 pixels at 45 degree from it's current position.

Orbit guided tweens

An orbit guide has a radius x, radius y, center x and a center y. Tweening the angle in degrees on the Orbit2D class defines where on the path the item is placed initially the path is at the angle 0.

import com.flashdynamix.motion.;
 import com.flashdynamix.motion.guides.Orbit2D;
 
var tween:TweensyGroup = new TweensyGroup();
 tween.to(new Orbit2D(myInstance, 100, 100, 250, 250), {degree:360});

This will orbit 'myInstance' 360 degrees on a x/y radius of 100 from the x/y center point of 250.

Bezier guided tweens

A bezier guide has a collection of points defining a bezier path. Tweening the position on the Bezier2D class defines where on the path the item is placed initially the path is at position 0 and ends at position 1.

import com.flashdynamix.motion.;
 import com.flashdynamix.motion.guides.Bezier2D;
 
var tween:TweensyGroup = new TweensyGroup();
 var bezier:Bezier2D = new Bezier2D(myInstance, true, false, false);
 bezier.push(new Point(100, 100));
 bezier.push(new Point(200, 150));
 bezier.push(new Point(300, 100));
 bezier.push(new Point(400, 300));
 tween.to(bezier, {position:1});

This will animate 'myInstance' along the bezier path defined from it's start position.
