Question

我试图在每次触摸某个区域时向下移动一个精灵节点。这是我的代码，日志显示触摸注册。我做错了什么，是否有更简单的方法来实现这一目标？

-(void)update:(CFTimeInterval)currentTime {

    CGPoint currentLocation = [currentTouch locationInView:currentTouch.view];

    if (currentLocation.y > 500) {


    CGFloat newY = _bg.position.y - 25;
    _bg.position = CGPointMake(_bg.position.x, newY);
    NSLog(@"touchtouch");
}

试试这个：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

for (UITouch *touch in touches) {

CGPoint currentLocation = [touch locationInNode:self];

if (currentLocation.y > 500) {


    CGFloat newY = _bg.position.y - 25;
    _bg.position = CGPointMake(_bg.position.x, newY);
    NSLog(@"touchtouch");
      }
   }
}

您还可以使用SKAction对动画进行动画处理：

SKAction *moveDown = [SKAction moveToY:newY duration:1];
    [_bg runAction:moveDown];

希望这可以帮到你！

在Sprite Kit中没有从sprite中获得任何移动
