Question

我的计时器出了问题。计时器结束后，我想让一些实例消失。但是，我收到错误1106.错误表明if语句是空的，应该有代码。但是，有代码（quickTimerBegin函数。）

  import flash.events.MouseEvent;
    import flash.utils.Timer;
    import flash.events.TimerEvent;

var F20quickTimer:Timer = new Timer(5000,1); 
F20quickTimer.addEventListener(TimerEvent.TIMER, quickTimerBegin); 

//checkmarks invisible at start 
F20next_btn.visible=false; 
F20chloroplastCheck_mc.visible=false; 
F20cytoplasmCheck_mc.visible=false; 
F20mitochondriaCheck_mc.visible=false; 
F20golgiCheck_mc.visible=false; 

//allows an instance to be dragged 
//allows an instance to be dropped 
F20chloroplasts_mc.addEventListener(MouseEvent.MOUSE_DOWN, drag); 
F20chloroplasts_mc.addEventListener(MouseEvent.MOUSE_UP, dropChloroplast); 
F20cytoplasm_mc.addEventListener(MouseEvent.MOUSE_DOWN, drag); 
F20cytoplasm_mc.addEventListener(MouseEvent.CLICK, dropCytoplasm); 
F20mitochondria_mc.addEventListener(MouseEvent.MOUSE_DOWN, drag); 
F20mitochondria_mc.addEventListener(MouseEvent.MOUSE_UP, dropMitochondria); 
F20golgi_mc.addEventListener(MouseEvent.MOUSE_DOWN, drag); 
F20golgi_mc.addEventListener(MouseEvent.MOUSE_UP, dropGolgi);

错误就在这里

**if((F20chloroplasts_mc.visible==true)&&(F20cytoplasmCheck_mc.visible==true)&&(F20mitochondriaCheck_mc.visible==true)&&(F20golgiCheck_mc.visible==true))
{
    function quickTimerBegin(event:TimerEvent):void{
        F20next_btn.visible=true; 
    }
}**

{
    event.target.startDrag(); 
    F20output_txt.text = "";

}

        F20golgi_mc.y= 535.15; 
    } 
}

我感谢所有的帮助！

我认为你是以错误的方式实施这项功能。
它应该是这样的

function quickTimerBegin(event:TimerEvent):void{
    if((F20chloroplasts_mc.visible==true)&&(F20cytoplasmCheck_mc.visible==true)&&(F20mitochondriaCheck_mc.visible==true)&&(F20golgiCheck_mc.visible==true))
    {
        F20next_btn.visible=true; 
    }
}

您可以控制计时器何时以F20quickTimer.start()开始。
如果F20quickTimer.reset()未满足条件，您可能需要重新启动计时器然后重新启动..或者增加 repeatCount ..
如果您知道documentation

，这将很容易

AS3 - 错误1106，无法使用Timer
