Stage layer Various usage:-----Best can analyze the source of the layer ...

1. General statements

var Helloworld = cc. Layer.extend ({

if (This._super ()) {return true;}

return false;

}); ----seldom used

22 Types of object creation

1) var pLayer = new Mylayer ();
Player.init ();----do not perform the ctor construction method and manually trigger the Init method.

2)
var layer = Mylayer (). Create ();

3. Automatic call execution method------> Rewrite the method inside the parent class, and call This._super ();

Ctor:init:onEnter:onExit:

Ctor:init:onEnter: creating a simple UI interface

OnExit: Releasing some resources

Such as:

Init:function () {

This._super ();

}
