Question

我为游戏制作了这段代码，我只是在学习，没有编译错误，但是当我运行代码时，它失败了没有错误。我有一行我想转到指定的帧，所以代码是Button_Object.gotoAndStop（Local_Frame）但看起来好像程序只是跳过它。我试图将_root.gotoAndstop（Local_Frame）和stage.gotoAndStop（Local_Frame）放在一起，但是这些都给出了编译器错误，它给出的错误是

 C:\Users\Nathan\Desktop\Matching Game\ClickSolver.as, 
 Line 34    1120: Access of undefined property _root.

我确实看到了跟踪声明。作为旁注，我试图访问主时间线，而不是对象时间轴。

这是代码

package  {
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.utils.Timer;
import flash.events.TimerEvent;

public class ClickSolver {
    private var Button_Object:MovieClip;
    private var Check_Object:MovieClip;
    private var Score:Number = 0;
    private var Local_Frame:Number = 0;
    private var Local_Timer:Timer = new Timer(1000,3);

    public function ClickSolver(ButtonObject:MovieClip, CheckObject:MovieClip, Frame:Number) {

        Local_Frame = Frame;
        Button_Object = ButtonObject;
        Check_Object = CheckObject;
        Button_Object.buttonMode = true;
        trace(Button_Object.name);
        trace(Check_Object.name);
        Local_Timer.start();
        trace(Local_Timer.currentCount);
        Button_Object.addEventListener(MouseEvent.CLICK, Object_Button_Clicked);
        Button_Object.addEventListener(MouseEvent.MOUSE_OVER,Button_Mouse_Over);
        Button_Object.addEventListener(MouseEvent.MOUSE_OUT, Button_Mouse_Out);
        Local_Timer.addEventListener(TimerEvent.TIMER_COMPLETE, TimerIsDone);

    }
    private function TimerIsDone (event:TimerEvent):void{
        trace("Timer is done");
        Local_Timer.stop();
        Local_Timer.reset();
        Button_Object.gotoAndStop(Local_Frame);
    }
    private function Button_Mouse_Out (event:MouseEvent):void{
        Button_Object.alpha = 1;
    }
    private function Button_Mouse_Over (event:MouseEvent):void{
        Button_Object.alpha = 0.75;
    }
    private function Object_Button_Clicked (event:MouseEvent):void{
        Score++;
        Check_Object.visible =  false;
        Button_Object.gotoAndStop(Local_Frame);
        trace("Score: " + Score);
        trace("Frame: " + Local_Frame);
    }

  }

   }

Answer 1

AS3不支持

_root。

尝试

MovieClip(root).gotoAndStop(local_Frame);

PS。代码的一个常见命名约定是使用较低的camelCase命名变量（即以小写字母开头）和具有较高CamelCase的名称类（即以大写字母开头）。

这将使您的代码更易于阅读，并允许您立即查看哪些项是变量和类。

gotoAndStop（）;不会正常工作
