Cocos2d-x turning on multi-touch points

Hard work and perseverance.

Add delegate

Addstandarddelegate ();

Turn on multi-touch

Settouchenabled ();

Touch Screen Event:

1. Register Multi-Touch

virtual void registerwithtouchdispatcher (void);

2. callback function that responds when the user first touches the phone screen

virtual void Cctouchesbegan (Ccset * touchs,ccevent * event);

3. Response callback function when the user's finger is sliding on the phone screen

virtual void cctouchesmoved (Ccset * touchs,ccevent * event);

4. callback function that responds when the user's finger leaves the phone screen

virtual void cctouchesended (Ccset * touchs,ccevent * event);

5. Add the open multi-touch code in the appcontroller.mm Didfinishlaunchingwithoptions method. As follows:

-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (Nsdictionary *) launchOptions {//Ove

    Rride point to 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:keaglcolor FormatRGBA8 depthformat:gl_depth_component16 PRESERVEB
                                 Ackbuffer:no Sharegroup:nil Multisampling:no
    NUMBEROFSAMPLES:0]; [__glview Setmultipletouchenabled:yes]; Add this code//use Rootviewcontroller manage Eaglview viewcontroller = [[Rootviewcontroller alloc] Initwithnibname:ni
    L Bundle:nil];
    Viewcontroller.wantsfullscreenlayout = YES; Viewcontroller.view = __glview; Set Rootviewcontroller to Window if ([[Uidevice currentdevice].systemversion Floatvalue] < 6.0) {/
    /Warning:addsubview doesn ' t work on iOS6 [window AddSubview:viewController.view];
    } else {//Use this method on IOS6 [window Setrootviewcontroller:viewcontroller];

    } [window makekeyandvisible];

    [[UIApplication sharedapplication] setstatusbarhidden:yes];
    Cocos2d::ccapplication::sharedapplication ()->run ();
return YES; }
