ios - SKSpriteNode 不稳定的滑动？

我创建了以下 Sprite 套件节点:

SKSpriteNode *megadeth;
megadeth = [SKSpriteNode spriteNodeWithImageNamed"megadeth_rocks.png"];
megadeth.name = @"awesome";

并添加滑动手势如下:

-(void)didMoveToViewSKView *)view{
   UISwipeGestureRecognizer *recognizerUp = [[UISwipeGestureRecognizer alloc] initWithTarget:self actionselector(handleSwipeUp];
recognizerUp.direction = UISwipeGestureRecognizerDirectionUp;
[[self view] addGestureRecognizer:recognizerUp];

UISwipeGestureRecognizer *recognizerDn = [[UISwipeGestureRecognizer alloc] initWithTarget:self actionselector(handleSwipeDn];
recognizerDn.direction = UISwipeGestureRecognizerDirectionDown;
[[self view] addGestureRecognizer:recognizerDn];
}

- (void)handleSwipeUpUISwipeGestureRecognizer *)sender{

     NSLog(@"Node Swiped Up");
     if (sender.state == UIGestureRecognizerStateEnded)
       {
        CGPoint touchLocation = [sender locationInView:sender.view];
        touchLocation = [self convertPointFromView:touchLocation];
        SKSpriteNode *touchedNode = (SKSpriteNode *)[self nodeAtPoint:touchLocation];
        if([touchedNode.name isEqualToString"awesome"]){
        NSLog(@"erform Action on AWESOME node");
        SKAction *moveUp = [SKAction moveByX:0.0 y0-touchedNode.position.y) duration:0.5];
        SKAction *fade = [SKAction fadeOutWithDuration:0.25];
        //SKAction *remove = [SKAction removeFromParent];
        SKAction *sequence = [SKAction sequence[moveUp, fade]];
        [touchedNode runAction:sequence];
      }
    }
}

当我滑动节点时，它会滑动，但它会回到原来的位置，然后淡出以移除。

我想要的是，当我刷卡时，它应该移动到刷卡的位置并移除。我在这里错过了什么吗？

我使用 [SKAction moveToY:duration:] 而不是 [SKAction moveByX:y:] ，这让一切都像魅力一样工作

这是更新后的 handleSwipeUp: 方法:

- (void)handleSwipeUpUISwipeGestureRecognizer *)sender{

 NSLog(@"Node Swiped Up");
 //if (sender.state == UIGestureRecognizerStateEnded)
   //{
    CGPoint touchLocation = [sender locationInView:sender.view];
    touchLocation = [self convertPointFromView:touchLocation];
    SKSpriteNode *touchedNode = (SKSpriteNode *)[self nodeAtPoint:touchLocation];
    if([touchedNode.name isEqualToString"awesome"]){
    NSLog(@"erform Action on AWESOME node");
    **SKAction *moveUp = [SKAction moveToYtouchedNode.position.y+200) duration:0.5];**
    //SKAction *fade = [SKAction fadeOutWithDuration:0.25];
    SKAction *remove = [SKAction removeFromParent];
    SKAction *sequence = [SKAction sequence[moveUp, remove]];
    [touchedNode runAction:sequence];
  }
//}

}

希望对你有帮助!!!
