的Flash AS3錯誤：1013：私有屬性只能在類的屬性定義

Question

C:\Users\Lab3project\MainDocument.as, Line 103, Column 7 1013: The private attribute may be used only on class property definitions.

      addChild(thePlayer); 
      // adjust its postion on the stage 
      thePlayer.x = stage.stageWidth * 0.5; 
      //assign the name property 
       thePlayer.name = "player"; 

       while(e < maxEnemies){

      //the main loop for the game 
      private function mainGameLoop(event:Event): void{ 

       checkForGameReset(); 

       processCollisions(); 

       scrollStage(); 

      } // end functiom mainGameLoop 
       private function checkForGameReset():void{ 
        //define conditions 
       } //end function checkForGameReset 

       private function processCollisions():void{ 
        //set up the main loop to look through all collidale objects on stage 
        for(var c:int;c < childOnStage;c++){ 
         //trace ("Child on stage c= " + c + 
         //test for a player of enemy child on stage 
      if (getChildAt(c).name == "player" || getChildAt(c).name == "enemy"){ 
       //see if object is touching the game stage 
       if(theGameStage.hitTestPoint(getChildAt(c).x, getChildAt(c).y,true)){ 
        //while it is still touching the game stage 
        while(theGameStage.hitTestPoint(getChildAt(c).x, getChildAt(c).y,true)==true){ 
         //called from CollisionObject class,so force the connection 
         CollisionObject(getChildAt(c)).incrementUpward(); 
        if(theGameStage.hitTestPoint(getChildAt(c).x, getChildAt(c).y,true)==false){ 
        }CollisionObject(getChildAt(c)).keepOnBoundary(); //make it stick 
        } // end if 
        } // end while 
       } //end if touching 
       } //end if player or enemy 
       } //end for loop 
      } //end function processCollisions 

The lines of code concerned: is here where im getting the error 
    private function scrollStage(): void 
    { 
     // figure out logic 
    } 
    // end function scrollStage 


      //add the enemy for testing 
      theEnemy = new Enemy(); 
      addChild(theEnemy); 
      // adjust its postion on the stage 
      theEnemy.x = stage.stageWidth * 0.5; 
      theEnemy.y = 200; 



     } // end public function MainDocument 

    } // end public class 


} // end package 

後，我有改變的代碼，它就會說我有一個額外的最後的角色，但最後我必須擁有的角色。

這樣的問題通常是由於語法上的輕微錯字而發生的。也許你不小心在另一個函數中聲明瞭你的私有函數？

public function doSomething() { 
    //a whole bunch of stuff 
//then we forget to close the function with a brace "}" 

private function scrollStage() { 
    //but we're still defining doSomething! Throw error! 
} 

去尋找這樣的錯誤，並希望你能找到問題。
