我试图通过FlashDevelop编写一种策略游戏，并且在尝试使用事件（尤其是MouseEvents）时遇到问题。事件并非如此，以至于事件正在返回错误，只是他们什么都不做，甚至没有追踪。
我试图在点击时使六边形HexObject图像不可见（只是一个简单的测试，看看MouseEvent是否真的有效）。
这是我的代码：
Main.as
package {
import flash.display.Shape;
import flash.display.Sprite;
import flash.events.Event;
import flash.events.MouseEvent;
/**

public class Main extends Sprite {

public var MIN_X:int = 0;
public var MAX_X:int = stage.stageWidth;
public var MIN_Y:int = 0;
public var MAX_Y:int = stage.stageHeight - 100;
public var GameGrid:HexGrid = new HexGrid(MIN_X, MAX_X, MIN_Y, MAX_Y);
public var blackBG:Shape = new Shape();
public function Main():void {
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, init);
addEventListener(Event.ENTER_FRAME, update);
// entry point
}
private function update(event:Event):void {
if (gameInitialised == false) {
GameGrid.initialiseGrid();
initialiseBackground();
gameInitialised = true;
}
updateGraphics();
}
public function drawGrid():void {
for (var x:int = 0; x < GameGrid.TOTAL_X; x++) {
for (var y:int = GameGrid.yArray[x][0]; y < GameGrid.yArray[x][1]; y++) {
if (x != GameGrid.nox || y != GameGrid.noy) {
GameGrid.Grid[x][y].update();
this.stage.addChild(GameGrid.Grid[x][y].image);
}
}
}
}
public function updateGraphics():void {
this.stage.addChild(blackBG);
drawGrid();
}
public function initialiseBackground():void {
blackBG.graphics.beginFill(0x000000, 1);
blackBG.graphics.lineStyle(10, 0xffffff, 1);
blackBG.graphics.drawRect(0, 0, stage.stageWidth-1, stage.stageHeight-1);

我尝试过无数种方法让事件发挥作用，但没有一种方法取得任何成功。任何形式的解决方案都可以成为救星，因为我已经为此工作了好几个小时，谢谢！
答案 0 :(得分：1)
我的问题由VBCPP修复，我使用的是无法调度MouseEvents的类Bitmap。解决方案是从image获取HexObject并将其放在Sprite类型的容器中，逻辑的是它所在的对象。我只需要在里面添加以下代码HexObject.as：
this.addChild(image);
然后在将来引用Object而不是image。
