是否有可能摧毁派遣的事件

我正在AS3制作游戏。

我有一个名为“UseBox”的类,用于调度事件。

如果thisThing.buyable not event is dispatch且子视图“Building”可见,其中2个建筑物可见且2个不可见。

如果thisThing.destructible那么事件“升级”是发送,并且子建筑物“建筑物”是可见的,其中4个建筑物可见。

问题是发送“可升级”现在一直在进行。

每次儿童“建筑物”变得可见时,是否可以销毁事件?

Thanx为你的答案,

这是我的代码:

UseBox

  public function UseBox(stageRef:Stage, thisThing:Object){
if (thisThing.buyable){
useButton.gotoAndStop("buy");
useButton.addEventListener(MouseEvent.CLICK, buyIt, false, 0, true);
}
    if (thisThing.destructible){
    this.gotoAndStop("upgrade");
    upgradeButton.buttonMode = true;
    upgradeButton.addEventListener(MouseEvent.CLICK, upgradeIt, false, 0, true);
                }

    public function buyIt(e:MouseEvent):void{
                boxClicked();
                showBatiments();
                lookButton.removeEventListener(MouseEvent.CLICK, buyIt);
            }
            public function upgradeIt(e:MouseEvent):void{
                boxClicked();
                showBatiments();
                        stageRef.dispatchEvent(new Event("upgradable"));
                lookButton.removeEventListener(MouseEvent.CLICK, buyIt);
            }
    private function showBatiments():void{
                Engine.batiments.visible = true;
                }

哦,还有我的buidling.as代码:

poulaillerPlusBtn.visible = false;
poulaillerImpossible.visible = true;
poulaillerBtn.addEventListener(MouseEvent.CLICK, poulaillerConstruction, false, 0, true);
stageRef.addEventListener("upgradable", checkConstruction, false, 0, true);


private function checkConstruction(Event):void{
            trace("I've heard upgradable");
            poulaillerPlusBtn.visible = true;
            poulaillerImpossible.visible = false;
            poulaillerPlusBtn.addEventListener(MouseEvent.CLICK, poulaillerAmelioration, false, 0, true);
            trace("on a vérifé, tu peux améliorer le batiment");
        }

因此,如果听到“升级”事件,则调用函数“checkConstruction”,否则不会。

但是,一旦调度了“升级”事件,它似乎始终保持调度,因此当“建筑物”可见时,总是调用“checkConstruction”功能...

我不是100%确定这是你正在寻找的东西,但是如果你只想要处理一次事件,那么一旦你通过调用checkConstruction收到它,你就可以删除它从再次听取事件:

private function checkConstruction(Event):void{
    //Here, you would remove the function from listening to any more "upgradable" events being dispatched. 
    stageRef.removeEventListener("upgradable", checkConstruction);


    trace("I've heard upgradable");
    poulaillerPlusBtn.visible = true;
    poulaillerImpossible.visible = false;
    poulaillerPlusBtn.addEventListener(MouseEvent.CLICK, poulaillerAmelioration, false, 0, true);
    trace("on a vérifé, tu peux améliorer le batiment");
}
