我正在尝试稍微重构我的代码（目前所有内容都在主类中）。我将我所有的播放器代码放在一个新的播放器类中。现在我尝试在主类中创建它的一个实例，但没有任何反应。我究竟做错了什么？

    var figur:Player;

    public function Main() {
        init();
    }

    private function init():void{
        figur = new Player();
        addChild(figur);
    }

播放器.as

package  {
import flash.display.Sprite;
import flash.display.MovieClip;
import flash.display.Shape;
import flash.events.Event;
import flash.display.Graphics;
import flash.events.MouseEvent;
import flash.display.LineScaleMode;
import flashx.textLayout.utils.CharacterUtil;

public class Player extends Sprite{

    public var line:Shape = new Shape();
    public var char = new CharSprite();
    public var _xStart:Number;
    public var _yStart:Number;
    public var _xZiel:Number;
    public var _yZiel:Number;var _mx:Number;
    public var _my:Number;
    public var _platformCollision:Boolean;
    const ACCELERATION:Number = 10;

    public function Main() {
        init();
    }

    private function init():void{
        _platformCollision = false;
        _xStart = 40;
        _yStart = 350;
        _xZiel = 40;
        _yZiel = 350;

        line.x = 40;
        line.y = 350;
        line.graphics.lineStyle(2,0x0000FF,1, false, LineScaleMode.NONE);
        line.graphics.lineTo(1,1);
        addChild(line);
        char.x = 40;
        char.y = 350;
        addChild(char);
        addEventListener(Event.ENTER_FRAME, mainLoop);
        stage.addEventListener(MouseEvent.MOUSE_DOWN, onClick);
    }

在播放器类中，调用播放器构造函数中的 init 函数。

我认为你应该在玩家添加到舞台时调用这一行，而不是在 init 函数中

 stage.addEventListener(MouseEvent.MOUSE_DOWN, onClick);

尝试这个

private function init():void {
  //your code

   this.addEventListener(Event.ADDED_TO_STAGE, onAddToStage);
}

private function onAddToStage(e:Event):void {
     stage.addEventListener(MouseEvent.MOUSE_DOWN, onClick);
}

首先，您的构造函数名称错误。其次，您可以收听 addedtostage 并在那里调用 init，而不是在 init 中收听 addedtostage （其他方式）

所以，改变这个

public function Main() {
    init();
}

至

//rename Main to Player
public function Player() {
    //wait untill added to stage
    addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
}

private function onAddedToStage(e:Event):void {
    //remove addedtostage event
    removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
    //call init
    init();
}
