Actionscript 3 左右两侧通过mose旋转对象

我必须做一个横幅广告（swf）。所以我在中间有一个圆圈对象，当你把鼠标移到右边时，我需要从左到右旋转，当你在左边移动鼠标时，从右向左开始旋转。有什么想法吗？谢谢

有很多方法可以做到这一点，但请先尝试一下，看看这是否就是您想要的：

private var rotationStep = .25;
private var newX:int;
private var oldX:int;

public Main():void {

   // Initialization of your stuff 

   // When ready add this to track the mouse
   this.stage.addEventListener(MouseEvent.MOUSE_MOVE,followMouse);

}
private function followMouse(e:MouseEvent):void {
    if(this.newX > this.oldX) {
        this.rotate(1);
    } else {
        this.rotate(-1);
    }
    this.oldX = this.newX;
}

private function rotate(dir:int):void {
    // rotate ball based on direction
    this.ball.rotoationZ += this.rotationStep*dir;
}

---

请记住，旋转是以弧度为单位的，而不是以度为单位的。有很多方法可以做到这一点，但请先尝试一下，看看这是否就是您想要的：

private var rotationStep = .25;
private var newX:int;
private var oldX:int;

public Main():void {

   // Initialization of your stuff 

   // When ready add this to track the mouse
   this.stage.addEventListener(MouseEvent.MOUSE_MOVE,followMouse);

}
private function followMouse(e:MouseEvent):void {
    if(this.newX > this.oldX) {
        this.rotate(1);
    } else {
        this.rotate(-1);
    }
    this.oldX = this.newX;
}

private function rotate(dir:int):void {
    // rotate ball based on direction
    this.ball.rotoationZ += this.rotationStep*dir;
}

记住旋转是弧度，不是度
