cocos2d-iphone – 在Coco2d中滑动

概述我试图让刷卡工作为Cocos2d最新版本这里是我的代码： -(void) setupGestureRecognizers { UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeLeft)]; [swip 我试图让刷卡工作为Cocos2d最新版本这里是我的代码：

-(voID) setupGestureRecognizers {    UISwipeGestureRecognizer *swipeleft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeleft)];    [swipeleft setDirection:UISwipeGestureRecognizerDirectionleft];    [swipeleft setNumberOftouchesrequired:1];    [[[CCDirector sharedDirector] openGLVIEw] addGestureRecognizer:swipeleft];}

它完全没有检测到滑动！

更新1：

我将代码更新为以下内容,但仍然没有检测到滑动.

-(voID) setupGestureRecognizers {    UISwipeGestureRecognizer *swipeleft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeleft)];    [swipeleft setDirection:UISwipeGestureRecognizerDirectionleft];    [swipeleft setNumberOftouchesrequired:1];    [[[[CCDirector sharedDirector] openGLVIEw] window] setUserInteractionEnabled:YES];    [[[CCDirector sharedDirector] openGLVIEw] setUserInteractionEnabled:YES];    [[[CCDirector sharedDirector] openGLVIEw] addGestureRecognizer:swipeleft];}

我也尝试过这项工作,但我发现了一种更简单,也更好的控制方法.

所以例如,如果你想要检测左边的滑动我会这样跟随.

在你的类的接口中声明两个变量

CGPoint firsttouch;CGPoint lasttouch;

在init方法中执行你的类启用touches

self.istouchEnabled = YES;

3.将这些方法添加到您的班级

-(voID)cctouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {    NSSet *alltouches = [event alltouches];    UItouch * touch = [[alltouches allObjects] objectAtIndex:0];    CGPoint location = [touch locationInVIEw: [touch vIEw]];    location = [[CCDirector sharedDirector] convertToGL:location];    //Swipe Detection Part 1    firsttouch = location;}-(voID) cctouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {    NSSet *alltouches = [event alltouches];    UItouch * touch = [[alltouches allObjects] objectAtIndex:0];    CGPoint location = [touch locationInVIEw: [touch vIEw]];    location = [[CCDirector sharedDirector] convertToGL:location];    //Swipe Detection Part 2    lasttouch = location;    //Minimum length of the swipe    float swipeLength = ccpdistance(firsttouch,lasttouch);    //Check if the swipe is a left swipe and long enough    if (firsttouch.x > lasttouch.x && swipeLength > 60) {        [self doStuff];    }}

如果发生左滑动,则调用方法“doStuff”.
