Really Simple yet Complicated Question:

How to make complicated tweenings in ActionScript?

Say if I got a arrow MC with instance name : myTweenObject
How do I make the arrow, (start with pointing upwards) twist 90 degrees CW in 30 frames, then twist 180 degrees AntiCW in 80 frames, then expand itself by 30%???
I know how to animate but how to continuesly animate something by AS?

heres one way:

Code:

---

//we want arrow to rotate 90 degrees in 30 frames which means in one frame we want it to rotate 90/30 = 3 degrees, hence:
var cwSpeed:Number = 3;

//we want arrow to rotate 180 degrees in 80 frames which means in one frame we want it to rotate 180/80 = 2.25 degrees hence:
var acwSpeed:Number = -2.25;


var expansionSpeed:Number = 1;
var speed:Number = cwSpeed;
var expand:Boolean = false;

_root.onEnterFrame = rotate;

function rotate() {
        //clockwise first
        myTweenObject._rotation += speed;
        if (myTweenObject._rotation == 90) {
                speed = acwSpeed;
        }
        if (myTweenObject._rotation == -90) {
                //now we dont want it to rotate so set speed to zero
                speed = 0;
                expand = true;
        }
        if (expand) {
                myTweenObject._xscale = myTweenObject._yscale += expansionSpeed;
                if (myTweenObject._xscale == 130) {
                        delete this.onEnterFrame;
                }
        }
}

Good one thanks!
