Question

我有按钮将影片剪辑添加到舞台上，当点击其他按钮添加另一个按钮时，它不会消失。我已经看过类似的问题，但没有一个答案对我有用。

btnBlue.addEventListener(MouseEvent.CLICK, fl_MouseOverHandler1);
function fl_MouseOverHandler1(evt: MouseEvent): void {
    var ballBlue: BallBlue = new BallBlue;
    addChild(ballBlue);
    addChildAt(ballBlue, 0);
    ballBlue.x = 100; //sets the x position
    ballBlue.y = 100; //sets the y position}

    function onClick(evt:MouseEvent):void {  */to remove clip if one is playing
        removeChildAt(0)
    }
}

btnRed.addEventListener(MouseEvent.CLICK, fl_MouseOverHandler2);
function fl_MouseOverHandler2(evt: MouseEvent): void {
    var ballRed: BallRed = new BallRed;
    addChild(ballRed);
    addChildAt(ballRed, 0);
    ballRed.x = 100; //sets the x position
    ballRed.y = 100; //sets the y position}
    parent.BallBlue.removeMovieClip(); 

    function onClick(evt:MouseEvent):void {  */to remove clip if one is playing
        removeChildAt(0)
    }
}

Answer 1

btnBlue.addEventListener(MouseEvent.CLICK, btnBlue_clickHandler);
btnRed.addEventListener(MouseEvent.CLICK, btnRed_clickHandler);

var ballBlue: BallBlue = new BallBlue();
var ballRed: BallRed = new BallRed();

function btnBlue_clickHandler(evt:MouseEvent):void {
    removeAllBalls();
    addChild(ballBlue);
    ballBlue.x = 100; //sets the x position
    ballBlue.y = 100; //sets the y position
}

function btnRed_clickHandler(evt:MouseEvent):void {
    removeAllBalls();
    addChild(ballRed);
    ballRed.x = 100; //sets the x position
    ballRed.y = 100; //sets the y position
}

function removeAllBalls():void {
    if (contains(ballBlue))
    {
        removeChild(ballBlue);
    }
    if (contains(ballRed))
    {
        removeChild(ballRed);
    }
}

如果播放，As3删除当前剪辑
