Cocoa 滑动CCMenu
我有一个包含Cocoa 滑动CCMenu,cocoa,cocos2d-iphone,Cocoa,Cocos2d Iphone,我有一个包含CCMenuItemImages的菜单(“myMenu”)。我想这个菜单来检测手指滑动和相应的幻灯片 我的问题是,CCMenuItemImages似乎吸收了触摸事件。当用户触摸CCMenuItemImages之外的菜单时,滑动工作正常,但当触摸这些图像时,滑动工作正常 我曾尝试将菜单项放在一个层中以检测触摸(参考答案),但这似乎也不起作用。知道为什么吗 +(id) scene { CCScene *scene = [CCScene node]; ModeMenuSce

我的问题是,CCMenuItemImage

我曾尝试将菜单项放在一个层中以检测触摸(参考答案),但这似乎也不起作用。知道为什么吗

如果(location.y>100&&location.y通过添加:
-(void) registerWithTouchDispatcher
{
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:INT_MIN+1 swallowsTouches:NO];
}
问题是CCMenuItemImage会吞下触摸,并将高优先级设置为-128。因此,需要将优先级设置为INT\u MIN+1
您在哪里添加了此代码?在包含CCMenuItemImage的CCScene类中,我也停留在同一点上
