COCOS2DX Development (4)--windows environment create COCOD2DX 3.2 first project HelloWorld

This article: cocos2dx+vs2013 environment to create projects, some code analysis. Friends of the meeting can skip.

In front of the simple installation of a few environments, the program can run smoothly (other cocos-stadio these need to be re-installed)

1. Create a custom project in the command line form

Open the cocos2d root directory, run the download-deps.py and setup.py once (you can start a new project directly if you have previously run)

Version 3.2 seems to be back in the form of commands, and it is not troublesome, so I have not found another way to create the project.

Here is a look at the two commands, enter each to see what parameters they have

Cocos and Cocos New

Cocos New project name –P package name –l cpp–d path

Official start: In the Cocos root directory shift opens the command window:

Cocos New Firstdemo-p com.huoit.firstdemo-l cpp-d F:\CocosDemo Enter

Some friends may think of the new project with batch processing, not complicated, direct reference to the user wrote, Save As. bat file next time directly run can

@echo off   =============cocos2d-x New Project ==============  set /P name= Enter the name of   the project:%name%    Echo Creating new Project    ... set pack=new %name%-P%pack%%name%-L CPP-  D F:\Cocos2dDemo echo Creation is complete. pause
    

Here I build project Firstdemo

2. Project Catalogue

After the creation is complete, open the solution Firstdemo\proj.win32\firstdemo.sln under the corresponding project directory. The following file structure

Open Win32 See Main.cpp\main.h Program entrance, classes folder defined Appdelegate and Helloworldscene

3, HelloWorld

Before you go on, learn the concepts of directors, scenes, layers, and sprites.

The director is a game flow controller, the next game can be divided into different scenes, a scene can be divided into different layers, a layer can also have any visible game nodes (that is, the game is basically all the classes are sent to node class nodes). You can perform an action to modify the properties of a game node so that it moves, rotates, zooms in, shrinks, and so on.

①:main.cpp Entrance, program walk

appdelegate app; //Inherit from application  return Application::getinstance ()->run (); //Run

②:appdelegate.h See the introduction of namespaces and macros, constructor destructor, here the main look at three functions represent the life cycle of the program, the first is the loading time to initialize the director scene these, the next two is the program background and backstage back to the foreground function (below), the source code in the comments are actually clear, you can view their own

    /* *    Load Initialization    *     /virtualbool  applicationdidfinishlaunching ();     /* *   foreground to Background run     */     virtualvoid  Applicationdidenterbackground ();     /* *    Background to the foreground    run */     virtualvoid Applicationwillenterforeground ();

corresponding to the implementation of the CPP, mainly to do the few things

Load: Initialize Director,glview, set fps. Initialize the scene, run;

Backstage: Director calls StopAnimation

Front Desk: Director calls Startanimation

③:helloworld, see it inherit layer

classHelloWorld: Publiccocos2d::layer{ Public:    //there ' s no ' id ' in CPP, so we recommend returning the class instance pointer    Staticcocos2d::scene*Createscene (); //Here ' s a difference. Method ' init ' in cocos2d-x returns BOOL, instead of returning ' ID ' in Cocos2d-iphone    Virtual BOOLinit (); //a selector callback    voidMenuclosecallback (cocos2d::ref*Psender); //implement the "Static Create ()" Method manuallyCreate_func (HelloWorld);};

HelloWorldScene.h

Before declaring a scene, initialize Init (), and a scheduling method. The main point here is a create_func (HelloWorld);

How to understand that, the definition of this macro is somewhat similar to the generic in C #, create () An instance of the corresponding type.

Cpp:

The Auto keyword is a bit like the C # var, but it should also be the right object type to be explicitly equal to

Director::getinstance ()->getvisiblesize (); Get the visible size

Director::getinstance ()->getvisibleorigin (); Get coordinates starting point

SetPosition Setting Location

AddChild (object, z-axis position): Recall the above tree structure, that is, the lower-level objects into the parent object container (Sprite join Layer,layer join scene)

Implementation notes in CPP very detailed, no more nonsense, here is just a summary of notes, and more look at the official documents and code

Also to say is from the simple HelloWorld see 3.2 inside of small changes, that is, the class cocos2d under the namespace is again encapsulated, see the previous version of the cc_break_if these are not seen, only from the writing concise a little
