onEnterFrame 的問題～

wildkyo

我有一個ball_mc，我摸up_mc它就會滾上去，onRollOut就停着我摸down_mc它就會滾下去，onRollOut就停着


ball_mc到y=10 和 y=400 就停了。


這是我的爛coding
up_mc.onRollOver = function() {

if (ball_mc._y<=400) {

ball_mc.onEnterFrame = function() {

ball_mc._y = ball_mc._y-2;

};

}
};
up_mc.onRollOut = function() {

delete ball_mc.onEnterFrame; //做它停
};



但是我第二次摸up_mc的時候就沒反應了哦

//////////
if (ball_mc._y == 10) {

delete ball_mc.onEnterFrame; //這是我要給ball_mc超過越位(y=10)就自動停
}

ball_mc不理我，它照樣走它的路




怎樣好？我個人覺得是onEnterFrame在作怪

因為你只是在 rollover 的时候判断 ball_mc 的 y 座标，而 ball_mc 在不断循环的時候却没限制着，所以只要把判断放在 onEnterFrame 事件中就可以了

up_mc.onRollOver = function() {

ball_mc.onEnterFrame = function() {
    if (ball_mc._y<=400) {
        ball_mc._y = ball_mc._y-2;
    } else {
        delete this.onEnterFrame;
    }
};
