Cocos2d-x for iOS multi-touch issues

Still reading study and practice, but the book of mistakes really ...

The first is Cclayer, which has written a class that inherits from Ccsprite, implements a single touch with the finger, overrides the begin,moved and end functions, and then sets and cancels the proxy in OnEnter and Oneixt. The example in the book is directly to the HelloWorld, not only rewrite the three functions, but also rewrite the Registerwithtouchdispatcher function, I write all to give a hint error, roughly ambiguous conversion from class HelloWorld to Cctouchdelegate kind of ~ ~ Actually because inherited the Cclayer function, so do not rewrite this. Replaced by the Ccsprite after this sentence will not error.

Then there is the multi-touch of the iOS simulator. The option key and the mouse, not the Apple keyboard, are alt and mouse. If you want to scale to size, it always fails. In the BEGIN function it was only judged that the contact was more than two, and there was a further judgment.

    if (Ptouches->count () = =1

Then two conditions to print different information, we found that using the ALT key to get is just a contact information ~ Although the simulator on the screen gave two ~

Had to ask Niang, the solution is in the iOS directory files need to change ~appcontroller this file ~ in

BOOL) Application: (uiapplication *) application didfinishlaunchingwithoptions: (nsdictionary *) Launchoptions

This function adds a sentence:[__glview setmultipletouchenabled: true];

Originally thought is in HelloWorld inside onenter Such add, always hold the wrong ... The original is here ~ ~

Then you can.

Another thing to note is the type of distance and scale ~ before the brain pumping set int, so the whole tragedy ~ ~
