如何使用C++在cocos2d-x ios游戏中启用多点触控

Question

我想在cocos2d-x中使用C++启用多点触控模式。有关于如何在cocos2d上启用它的答案，但是我想在cocos2d-x中启用它。任何帮助将不胜感激

Answer 1

我自己得到了答案。为了启用多点触控只需去你的AppController.mm 然后在函数didFinishLaunchingWithOptions创建EAGL视图后只需添加下面的代码。

[__glView setMultipleTouchEnabled:YES]; 

所以，现在的功能应该是这样的

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary  
*)launchOptions { 

// Override point for customization after application launch. 

// Add the view controller's view to the window and display. 
window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]]; 
EAGLView *__glView = [EAGLView viewWithFrame: [window bounds] 
           pixelFormat: kEAGLColorFormatRGBA8 
           depthFormat: GL_DEPTH_COMPONENT16 
          preserveBackbuffer: NO 
            sharegroup: nil 
           multiSampling: NO 
          numberOfSamples:0 ]; 

[__glView setMultipleTouchEnabled:YES]; 
// Use RootViewController manage EAGLView 
viewController = [[RootViewController alloc] initWithNibName:nil bundle:nil]; 
viewController.wantsFullScreenLayout = YES; 
viewController.view = __glView; 
//continued.....

对于其他平台，这应该是在默认情况下，但针对iOS您需要启用它。从Cocos2d-x 3.16开始，修改cocos new命令行工具生成的RootViewController.mm的一行，以启用多点触控。
