COCOS2DX Lua Learning Notes < a > Quick 3.5 binding Custom C + + classes to Lua

Please respect the original reprint please famous source: http://blog.csdn.net/wushao126/article/details/46660375
First go to the official website to download the latest quick, configure the environment, create a LUA project, command Cocos New XXX (project name)-P com.xxxx.xxxx (package name)-L lua-d XXX (new Project Save path)

After the project is created, locate the frameworks\runtime-src\classes in the project directory, create a C + + class, and the class I created is

File name: LuaBindingTest.h

#pragma onceclass luabindingtest{public:luabindingtest (); ~luabindingtest (); void Add (long a,long b); void sub (int a, int b);};

File name: LuaBindingTest.cpp

#include "LuaBindingTest.h" #include "cocos2d.h" USING_NS_CC; Luabindingtest::luabindingtest () {}luabindingtest::~luabindingtest () {}void luabindingtest::sub (int a, int b) {CCLOG ( "A-B =%d",-a);} void Luabindingtest::add (Long A, long B) {Cclog ("a + b =%ld", A + b);}

After that, locate the genbindings.py folder in the Frameworks\cocos2d-x\tools\tolua folder in the project directory, back up a copy, change the name Genbindings_binding_ test.py, open this file, you need to modify the content, positioning about 130 lines, find content similar

        Tolua_root = '%s/tools/tolua '% project_root output_dir = '%s/'.                     /runtime-src/classes/auto '% project_root Cmd_args = {' Myclass.ini ': (' MyClass ', ' Lua_myclass_auto '), ' Cocos2dx_extension.ini ': (' cocos2dx_extension ', ' Lua_cocos2dx_extension_auto '), ' cocos2dx_ui . ini ': (' cocos2dx_ui ', ' Lua_cocos2dx_ui_auto '), ' Cocos2dx_studio.ini ': (' Cocos2dx_studio ', ' Lua_coco                     S2dx_studio_auto '), ' Cocos2dx_spine.ini ': (' cocos2dx_spine ', ' Lua_cocos2dx_spine_auto '), ' Cocos2dx_physics.ini ': (' cocos2dx_physics ', ' Lua_cocos2dx_physics_auto '), ' cocos2dx_experime Ntal_video.ini ': (' cocos2dx_experimental_video ', ' Lua_cocos2dx_experimental_video_auto '), ' cocos2dx_e Xperimental.ini ': (' cocos2dx_experimental ', ' Lua_cocos2dx_experimental_auto '), ' cocos2dx_controller.i     Ni ': (' Cocos2dx_controller ', ' Lua_cocos2dx_controller_auto '),                ' Cocos2dx_cocosbuilder.ini ': (' cocos2dx_cocosbuilder ', ' Lua_cocos2dx_cocosbuilder_auto '), ' Cocos2dx_cocosdenshion.ini ': (' cocos2dx_cocosdenshion ', ' Lua_cocos2dx_cocosdenshion_auto '), ' Coco S2dx_3d.ini ': (' cocos2dx_3d ', ' Lua_cocos2dx_3d_auto '), ' Cocos2dx_audioengine.ini ': (' Cocos2dx_audioeng Ine ', ' Lua_cocos2dx_audioengine_auto '), ' Cocos2dx_csloader.ini ': (' cocos2dx_csloader ', ' lua_cocos2dx_ Csloader_auto '),}

Tolua_root is the directory where the INI file is located, we will create our INI file in this directory.

Output_dir is the file directory where we want to build the target file, and I'll change this in the Classes directory auto

This is the content of my modified file

        Tolua_root = '%s/tools/tolua '% project_root        output_dir = '%s/'. /runtime-src/classes/auto '% project_root        Cmd_args = {' Myclass.ini ': (' MyClass ', ' Lua_myclass_auto '),                     }

Myclass.ini is the INI file to be created next

Randomly copy an INI file, rename to Myclass.ini, open the file, modify a few parameters can be

prefix = MyClass

Target_namespace = (empty indicates no)

headers =% (Cocosdir) s/: /runtime-src/classes/luabindingtest.h (requires binding the header file path of the C + + Class)

Classes = Luabindingtest (class name)

Skip = (interface hidden from LUA)

Save the file after you have modified it. Then you configure the environment

Locate the Readme.mdown file under this directory to open

Follow the above installation, do well, about cheetah this, directly copy the folder, do not enter the directory to put all the files scattered into the C:\Python27\Lib\site-packages

The NDK r9b version is better than that.

When the environment is well configured

Execute the Python genbindings_binding_test.py command

You will see the generated files, API folders, a HPP, a CPP on your output_out path. If the BAA generated, it is necessary to check whether the error link.

Registered

Open AppDelegate.cpp, add hpp header file

Appdelegate::applicationdidfinishlaunching method, under Lua_module_register (l), copy the HPP just generated in Register_all_myclass (L);

This is a good sign.

Call

Local p = luabindingtest.new (0)
P:add (4,1)
P:sub (2,1)
