错误 #1502：脚本的执行时间超过了默认的 15 秒时间段

Question

这是我第一次使用 AS3，如果这个问题的原因非常明显，我深表歉意。

我正在下棋，棋盘上的每个棋子都有一个 class。当轮到玩家 1 时，所有黑色棋子都应该等待被点击，但是当我实现它时 returns 错误 #1502。

package chess.sprites{

import flash.display.MovieClip;
import flash.events.MouseEvent;

public class BlackBishop extends MovieClip{

    public function BlackBishop(){
        trace("bb created");
    }

    public function waitForClick(){
        this.addEventListener(MouseEvent.MOUSE_DOWN, myTurn);
    }

    protected function myTurn(me:MouseEvent){
        trace("Clicked");
    }

}

}

BlackBishop 中的函数 waitForClick() 正在被另一个 class 这样调用。

public function setBlackTurn(){
        for(var i:int = 0;i < 8;i++){
            blackPawn[i].waitForClick();
        }
        for(var i:int = 0;i < 2;i++){
            blackRook[i].waitForClick();
            blackKnight[i].waitForClick();
            blackBishop[i].waitForClick();
        }
        blackQueen.waitForClick();
        blackKing.waitForClick();
    }

我已经阅读了很多关于错误 #1502 的资料，但它似乎只在我在 BlackBishop 中添加侦听器时才会发生。有什么想法吗？

框架中的代码：

import chess.*;

var turn:int = 1;//1 is black, 2 is white
var gameRunning:Boolean = false;

var game:Game = new Game();
addChild(game);
game.addSprites();
game.resetArray();
gameRunning = true;

while(gameRunning){
    if(turn == 1){
        game.setBlackTurn();
    }else if(turn == 2){
        game.setWhiteTurn();
    }else{

    }
}

您的问题出在这里：

gameRunning = true;

while(gameRunning){
    ....
}

while 循环将锁定线程，直到 gameRunning 等于 false。这可能不会在 15 秒内发生。（根据您共享的代码，我不认为它会发生）

您可能习惯于使用游戏循环的其他语言。在 AS3 中，游戏循环需要在输入帧处理程序或计时器滴答中完成。

从代码的外观来看，发生的事情是，您一遍又一遍地切换转弯，并且您在一个循环中以运行尽可能快的速度这样做锁定 UI.

去掉那个while循环。反正我不明白你怎么需要它。您想在玩家移动棋子后改变回合。

以下是有关如何构建此应用程序的提示：

制作一个基础class，每个部分都可以延伸。这样您就不必编写冗余代码。因此，制作一个名为 ChessPiece 的 class 并使其扩展 MovieClip（或者 Sprite，如果您的片段不使用时间轴）。然后让你所有的作品扩展 ChessPiece class。现在它们都将具有您在基础 class (ChessPiece).

当您改变轮次时，只需将鼠标事件锁定在属于其他颜色的棋子上。如果您制作两个容器，这可能真的很容易：

 var blackContainer:Sprite = new Sprite(); 
 addChild(blackContainer);

 var whiteContainer:Sprite = new Sprite();
 addChild(whiteContainer);

 //then in your for loops where you create your pieces, add them to the appropriate container
 blackContainer.addChild(blackPawn[i]);

 //then you can do this when the turn changes to white:
 blackContainer.mouseChildren = false;  //now none of the pieces can dispatch mouse events / be clicked
