我对 iOS、Objective C 和使用 Xcode 还是很陌生。我只做了一个简单的新闻类应用程序,但现在我想创建一个我在另一个平台上发布的游戏。
基本上,我有一个对象会随机出现然后淡出,目的是点击对象使其消失。
但是,即使我设置了,我似乎也无法点击该对象 mySKSpriteNode.userInteractionEnabled = YES;
这是我的touchesBegan
方法中的内容:
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
/* Called when a touch begins */
NSLog(@"Something was touched");
UITouch *touch = [touches anyObject];
NSLog(@"%@", touch);
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
if(node == mySKSpriteNode)
[node runAction:[SKAction fadeOutWithDuration:0]];
}
在我的日志中,当我点击屏幕(不是我有对象的地方)时,我得到了这个:
2014-02-17 23:18:30.870 BubbleChallenge[48541:70b] Something was touched
2014-02-17 23:18:30.875 BubbleChallenge[48541:70b] <UITouch: 0x1130ea530> phase: Began tap count: 1 window: <UIWindow: 0x109c2ab60; frame = (0 0; 320 568); autoresize = W+H; gestureRecognizers = <NSArray: 0x109c274d0>; layer = <UIWindowLayer: 0x109c26810>> view: <SKView: 0x109c2e5e0; frame = (0 0; 320 568); autoresize = RM+BM; layer = <CAEAGLLayer: 0x109c0e180>> location in window: {147.5, 128.5} previous location in window: {147.5, 128.5} location in view: {147.5, 128.5} previous location in view: {147.5, 128.5}
当我触摸 mySKSpriteNode 时,我在日志中什么也没有得到,甚至没有“某物被触摸”;
知道为什么会发生这种情况吗?
我发现的其他问题说答案是设置userInteractionEnabled = YES
....也许代码中有一个特定的点我应该设置这个?..
感谢所有帮助!
