急求..为什么我写的不能循环.只能点一次.......

复制内容到剪贴板

代码:

var rember:Number = new Number();
//记忆变量
var target:Number = -30;
//目标角度
var max:Number = 2;
//最大旋转圈数
var speed:Number = 30;
//旋转速度
btn.onRelease = function() {
    mc.onEnterFrame = function() {
        if (rember<max) {
            mc._rotation += speed;
        } else {
            mc._rotation -= (target+this._rotation)/20;
        }
        if (mc._rotation == 0) {
            rember++;
        }
        if (mc._rotation>Math.abs(target)-0.1 & rember>=max) {
            delete mc.onEnterFrame;
        }
    };
};
