[BezierThrough] different result [solved]

[nokiaddt]

Class with a bezierThrough function

package home.here {
import com.greensock.TweenMax;
import com.greensock.data.TweenMaxVars;

public class MyClass{
	public function MyClass() {}

	public function bezierThrough (target:Object, toXY:String):void {
		var xyArray:Array = toXY.split(",");
		var tmpArray:Array = new Array(xyArray.length / 2);

		var moveItVars:TweenMaxVars = new TweenMaxVars();
		for(var i:int = 0; i < xyArray.length / 2; i ++) {
			tmpArray[i] = new Object();
			tmpArray[i].x = xyArray[i * 2];
			tmpArray[i].y = xyArray[i * 2 + 1];
		}

		TweenMax.to(target, 5, moveItVars);
	}
}

 

main mxml with an image which location is (70,300)

<?xml version="1.0" encoding="utf-8"?>

 

The motion of image should be start from (70,300) -> (130,0) -> (330,300), but the result is (70,300) -> (200,300) -> (400,600).

Can you tell me where the problem is?

Thanks a lot.

That must not be the real code because I don't see where you're populating your moveItVars. According to your code, nothing should happen at all actually. It looks like you omitted the moveItVars.bezierThrough(tmpArray), right?

[nokiaddt]

sorry for wrong code.

actually I have that code like

   public function bezierThrough (target:Object, toXY:String):void {
        var xyArray:Array = toXY.split(",");
        var tmpArray:Array = new Array(xyArray.length / 2);

        var moveItVars:TweenMaxVars = new TweenMaxVars();
        for(var i:int = 0; i < xyArray.length / 2; i ++) {
           tmpArray[i] = new Object();
           tmpArray[i].x = xyArray[i * 2];
           tmpArray[i].y = xyArray[i * 2 + 1];
        }
        moveItVars.bezierThrough(tmpArray)
        TweenMax.to(target, 5, moveItVars);
     }

and hope (or not) you can find the same result like what I said.

I try to execute the code by my home computer using Flash Builder 4.

And I got the same result. The executable code is ...

Main.mxml

<?xml version="1.0" encoding="utf-8"?>
				   xmlns:s="library://ns.adobe.com/flex/spark" 
				   xmlns:mx="library://ns.adobe.com/flex/mx">

home.nokiddt.BezierThrough.as

package home.nokiaddt {
import com.greensock.TweenMax;
import com.greensock.data.TweenMaxVars;

public class BezierThrough {
	public function BezierThrough() {

	}
	public function bezierThrough (target:Object, toXY:String):void {
		var xyArray:Array = toXY.split(",");
		var tmpArray:Array = new Array(xyArray.length / 2);

		var moveItVars:TweenMaxVars = new TweenMaxVars();
		for(var i:int = 0; i < xyArray.length / 2; i ++) {
			tmpArray[i] = new Object();
			tmpArray[i].x = xyArray[i * 2];
			tmpArray[i].y = xyArray[i * 2 + 1];
		}
		moveItVars.bezierThrough(tmpArray)
		TweenMax.to(target, 5, moveItVars);
	}
}
}

It looks like the problem is that you're passing Strings instead of Numbers as the values. Remember, TweenMax interprets Strings as relative values, not absolute. So just cast your values as Numbers and you'll be fine:

 

tmpArray[i].x = Number(xyArray[i * 2]);
tmpArray[i].y = Number(xyArray[i * 2 + 1]);

Oh, you got it. Thanks
