AS3-Event.ENTER_FRAME-错误1119 [英] AS3 - Event.ENTER_FRAME - error 1119

问题描述

我正在尝试使用Adobe Animate和AS3开发一个简单的游戏.

I'm trying to develop a simple game in Adobe Animate and AS3.

我有一个类GameCore，我想在其中添加ENTER_FRAME事件侦听器.

I have a class GameCore where I want to add an ENTER_FRAME event listener.

package as3 {

import flash.display.Stage;
import flash.display.MovieClip;
import flash.events.*;
import as3.movieclips.RocketShip;


public class GameCore {

    var rocket:RocketShip;
    var stage:Stage;
    var timeline:MovieClip;
    var i:int;

    public function GameCore( stage:Stage ) {
        // constructor code
        this.rocket = new RocketShip();
        this.stage = stage;
        this.timeline = this.stage as MovieClip;
        this.i = 0;
        this.stage.addEventListener(Event.ENTER_FRAME, gameLoop);
    }

    public function goToMainScreen():void {
        this.timeline.goToAndStop("MainScreen");
    }

    public function goToGameScreen():void {
        this.timeline.goToAndStop("GameScreen");
    }

    public function startGameLoop():void {

    }

    public function gameLoop(event:Event){
        trace(this.i);
        this.i += 1;
    }

}

}

当我尝试在时间轴框架上执行代码时，如下所示:

When I try to execute the code on a timeline frame like so:

  import as3.GameCore;
  var game:GameCore = new GameCore(stage);

它抛出一个错误，说:

 Can´t access probably undefined property ENTER_FRAME referenced with static type Class

我以前是这样做的，但是我几年都没碰过as3了，你能告诉我这里出了什么问题吗?

i did this before, but i don't touch as3 for a couple of years, can you tell me whats going wrong here?

感谢您提前编程！

推荐答案

好的，所以这可能是一个长镜头，但我认为您不必在其中包含(stage).您可以设置game.x和game.y以及其他一些变量，然后设置stage.addchild(game).如果您想要多个这种类型的对象，有时创建一个数组会有所帮助，但是您还需要做其他语义上的工作.

Ok so this might be a long shot but I don't think you have to have the (stage) in there. You can set game.x and game.y, and a few other variables, and then stage.addchild(game). if you want multiple objects of that type it is sometimes helpful to make an array, but there are other semantic stuff you have to do to make that work.
