【问题描述】：

我有一个带有实例名称为“mc”的影片剪辑的舞台。目前我有一个假设左右移动播放器的代码，当释放左右键时，“mc”会滑动一点。我遇到的问题是使“mc”向左移动有效，但用于右边的确切代码却没有。

所有这些代码都出现在主舞台 - 第一帧

//Variables

var mcSpeed:Number = 0;//MC's Current Speed
var mcJumping:Boolean = false;//if mc is Jumping
var mcFalling:Boolean = false;//if mc is Falling
var mcMoving:Boolean = false;//if mc is Moving
var mcSliding:Boolean = false;//if mc is sliding
var mcSlide:Number = 0;//Stored for use when creating slide
var mcMaxSlide:Number = 1.6;//Max Distance the object will slide.

//Player Move Function
p1Move = new Object();
p1Move = function (dir:String, maxSpeed:Number) 
 if (dir == "left" && _root.mcSpeed<maxSpeed) 
  _root.mcSpeed += .2;
  _root.mc._x -= _root.mcSpeed;
  else if (dir == "right" && _root.mcSpeed<maxSpeed) 
  _root.mcSpeed += .2;
  _root.mc._x += _root.mcSpeed;
  else if (dir == "left" && speed>=maxSpeed) 
  _root.mc._x -= _root.mcSpeed;
  else if (dir == "right" && _root.mcSpeed>=maxSpeed) 
  _root.mc._x += _root.mcSpeed;
 


//onEnterFrame for MC
mc.onEnterFrame = function():Void  
 if (Key.isDown(Key.LEFT)) 
  if (_root.mcMoving == false && _root.mcSliding == false) 
   _root.mcMoving = true;
   else if (_root.mcMoving == true && _root.mcSliding == false) 
   _root.p1Move("left",5);
  
  else if (!Key.isDown(Key.LEFT)) 
  if (_root.mcMoving == true && _root.mcSliding == false) 
   _root.mcSliding = true;
   else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide<_root.mcMaxSlide) 
   _root.mcSlide += .2;
   this._x -= .2;
   else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide>=_root.mcMaxSlide) 
   _root.mcMoving = false;
   _root.mcSliding = false;
   _root.mcSlide = 0;
   _root.mcSpeed = 0;
  
  else if (Key.isDown(Key.RIGHT)) 
  if (_root.mcMoving == false && _root.mcSliding == false) 
   _root.mcMoving = true;
   else if (_root.mcMoving == true && _root.mcSliding == false) 
   _root.p1Move("right",5);
  
  else if (!Key.isDown(Key.RIGHT)) 
  if (_root.mcMoving == true && _root.mcSliding == false) 
   _root.mcSliding = true;
   else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide<_root.mcMaxSpeed) 
   _root.mcSlide += .2;
   this._x += .2;
   else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide>=_root.mcMax) 
   _root.mcMoving = false;
   _root.mcSliding = false;
   _root.mcSlide = 0;
   _root.mcSpeed = 0;
  
 
;

我只是不明白为什么当你按左箭头时它工作得很好，但是当你按右箭头时它没有响应。它实际上是相同的代码。

【参考方案1】：

因为你的循环代码，你从来没有读过它：

if(keyleft)
    //catches all keyleft

else if(!keyleft)
    //katches all non key left

else if(keyright)
    //Never called because all eventualities have been covered by the above.

使用if(keyright) 而不是else if，它应该可以工作。
