多點觸控和ccTouchesMoved，laggy移動

Question

我有一個pong遊戲，我用手指移動槳。有一根手指時，一切順利。但是當我想要控制兩名選手，兩名選手時，一名選手的動作很好，但另一名選手動作非常遲緩。當第二個槳開始移動時，我的第一個槳停止。我該如何讓這兩種動作順暢且反應靈敏？

我在我的導演中啓用了多點觸控功能。

這裏是我的觸動代碼：

- (void) ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *myTouch = [touches anyObject]; 
    CGPoint location = [myTouch locationInView:[myTouch view]]; 
    location = [[CCDirector sharedDirector] convertToGL:location]; 
    CGRect leftTouchZone = CGRectMake(0, 0, 50, 320); 
    CGRect rightTouchZone = CGRectMake(430, 0, 50, 320); 

    if (CGRectContainsPoint(leftTouchZone, location)) 
    { 
     CGPoint tempLoc = location; 
     tempLoc.x = paddle1.position.x; 
     paddle1.position = tempLoc; 
    } 

    if (CGRectContainsPoint(rightTouchZone, location)) 
    { 
     CGPoint tempLoc = location; 
     tempLoc.x = paddle2.position.x; 
     paddle2.position = tempLoc; 
    }

不應該您完成所有的觸摸看對象，而不是僅僅抓住任何對象？如果您同時移動兩次觸摸，則只有一個觸摸移動事件。

- (void) ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    for (UITouch* myTouch in touches) 
    { 
     CGPoint location = [myTouch locationInView:[myTouch view]]; 
     location = [[CCDirector sharedDirector] convertToGL:location]; 
     CGRect leftTouchZone = CGRectMake(0, 0, 50, 320); 
     CGRect rightTouchZone = CGRectMake(430, 0, 50, 320); 

     if (CGRectContainsPoint(leftTouchZone, location)) 
     { 
      CGPoint tempLoc = location; 
      tempLoc.x = paddle1.position.x; 
      paddle1.position = tempLoc; 
     } 

     if (CGRectContainsPoint(rightTouchZone, location)) 
     { 
      CGPoint tempLoc = location; 
      tempLoc.x = paddle2.position.x; 
      paddle2.position = tempLoc; 
     } 
    }
