如何使用CCTouchMoved在Cocos2d中以速度/速度拖動CCSprite？

Question

我有一個精靈，我想通過使用我的手指移動屏幕〜拖動來移動它。 我希望我的精靈能夠隨着速度移動，這意味着不會像我的手指移動那麼快。

它看起來像這個視頻：http://www.youtube.com/watch?v=Vair3CIxZEw（從0:12到0:53）

這是我ccTouch代碼。我怎樣才能修復，讓它移動看起來更順暢？

謝謝!!! :)

簡單地返回TRUE

-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { 
    return TRUE; 
} 

和

-(void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event { 
    CGPoint touchLocation = [self convertTouchToNodeSpace:touch]; 

    CGPoint oldTouchLocation = [touch previousLocationInView:touch.view]; 
    oldTouchLocation = [[CCDirector sharedDirector] convertToGL:oldTouchLocation]; 
    oldTouchLocation = [self convertToNodeSpace:oldTouchLocation]; 


    CGPoint translation = ccpSub(touchLocation, oldTouchLocation); 
    if (CGRectContainsPoint(_car.boundingBox, touchLocation)) {    
     CGPoint newPos = ccpAdd(_car.position, translation); 
     _car.position = newPos; 
    } 
}

嘗試使用CCMoveTo行動平穩移動

CGPoint translation = ccpSub(touchLocation, oldTouchLocation); 
if (CGRectContainsPoint(_car.boundingBox, touchLocation)) { 
    CGPoint newPos = ccpAdd(_car.position, translation); 
    id moveAction = [CCMoveTo actionWithDuration:0.5f position:newPos]; 
    [_car runAction:moveAction]; 
}
