我是iOS的新手,目标C和使用
Xcode.我只做了一个简单的新闻类型的应用程序,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,我有一个对象随机出现然后淡出,目的是点击对象使其消失.
但是我似乎无法点击该对象,即使我设置了mySKSpriteNode.userInteractionEnabled = YES;
这是我在touchesBegan方法中所拥有的：
-(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,当我点击屏幕时(不是我有对象的地方),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} prev@R_301_437@s location in window: {147.5,128.5} location in view: {147.5,128.5} prev@R_301_437@s location in view: {147.5,128.5}
当我触摸mySKSpriteNode时,我在日志中什么也得不到,甚至没有“触及的东西”;
知道为什么会这样吗？
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点我应该设置它？
所有帮助表示赞赏！
解决方法
您是否尝试过设置spritenode的name属性？
在mySKSpriteNode的初始化中：
mySKSpriteNode = [[SKSpriteNode alloc] initWithTexture:sometexture]; mySKSpriteNode.name = @"thisIsMySprite"; // set the name for your sprite mySKSpriteNode.userInteractionEnabled = NO; // userInteractionEnabled should be disabled
然后：
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
if ([node.name isEqualToString:@"thisIsMySprite"]) {
NSLog(@"mySKSpriteNode was touched!");
[node runAction:[SKAction fadeOutWithDuration:0]];
}
}
