Cocos custom classes bound to Lua

1: Follow the instructions of \frameworks\cocos2d-x\tools\tolua under Readme.mdown step by step. Be sure to do as described in the document, I have been the pit of the father's things very miserable. (check if this is a good way to do this: Run the next genbindings.py to see if you can generate Liblua files in the Auto directory.) If you can, then your environment configuration will succeed. ）

2: Write a custom C + + class

Example:

<span style= "FONT-FAMILY:KAITI_GB2312;FONT-SIZE:14PX;" > #pragma once#include "cocos2d.h" Using_ns_cc;class myclass:public ref{public:myclass (void); ~myclass (void); bool Init () {return true;}; Create_func (MyClass); int foo (int i);}; </span>

<span style= "FONT-FAMILY:KAITI_GB2312;FONT-SIZE:14PX;" > #include "MyClass.h" myclass::myclass (void) {}myclass::~myclass (void) {}int myclass::foo (int i) {return i + 100;} </span>

3: In the \frameworks\cocos2d-x\tools\tolua directory you can see a lot of. ini files and a Genbindings.python file.

To copy an. ini file, I rename: Myclass.ini. Copy a python file and rename it as: Mygenbindings.python.

Modify two configuration files:

The python file needs to be modified:

<span style= "FONT-FAMILY:KAITI_GB2312;FONT-SIZE:14PX;" > Cmd_args = {' Cocos2dx.ini ': (' cocos2d-x ', ' Lua_cocos2dx_auto '), ' Cocos2dx_extension.ini ': (' coc Os2dx_extension ', ' Lua_cocos2dx_extension_auto '), ' Cocos2dx_ui.ini ': (' cocos2dx_ui ', ' lua_cocos2dx_ui                     _auto '), ' Cocos2dx_studio.ini ': (' Cocos2dx_studio ', ' Lua_cocos2dx_studio_auto '), ' Cocos2dx_spine.ini ': (' cocos2dx_spine ', ' Lua_cocos2dx_spine_auto '), ' Cocos2dx_physics.ini ': (' Cocos 2dx_physics ', ' Lua_cocos2dx_physics_auto '), ' Cocos2dx_experimental_video.ini ': (' Cocos2dx_experimenta L_video ', ' Lua_cocos2dx_experimental_video_auto '), ' Cocos2dx_experimental.ini ': (' cocos2dx_experiment Al ', ' Lua_cocos2dx_experimental_auto '), ' Cocos2dx_controller.ini ': (' Cocos2dx_controller ', ' Lua_cocos 2dx_controller_auto '),}</span>

Into:

<span style= "FONT-FAMILY:KAITI_GB2312;FONT-SIZE:14PX;" >cmd_args = {' Myclass.ini ': (' MyClass ', ' Lua_myclass_auto '),                     }</span>

To modify the Myclass.ini file:

[MyClass] ( It's important to be the same as the file name.) I've been in this hole for a long time ) This is the first line

prefix = MyClass

Target_namespace = (my no namespace)

headers =% (Cocosdir) s/: /runtime-src/classes/myclass.h (This is my classpath, and appdelegate together, according to your own path configuration bar)

Classes = MyClass

The following skip =, Rename_functions = And so on are all turned empty.

This makes it possible to generate Lua and Cocos intermediate files. Just like Lua_cocos2dx_auto.cpp and HPP. Since we did not change the build path of the intermediate file in the Python file, it should be in the same directory as the Lua_cocosdx_auto.

Register our custom classes and add code to the AppDelegate.cpp file:

<span style= "FONT-FAMILY:KAITI_GB2312;FONT-SIZE:14PX;" >auto engine = Luaengine::getinstance (); Register_all_myclass (Engine->getluastack ()->getluastate ());// Add this line of code here </span>

This allows us to register our custom classes.

Compile the project and find an error:

<pre name= "code" class= "HTML" ><span style= "FONT-FAMILY:KAITI_GB2312;FONT-SIZE:14PX;" > "int __cdecl register_all_myclass (struct lua_state *)" ([email Protected]@[email protected]@@z), the symbol in the function "public: virtual bool __thiscall appdelegate::applicationdidfinishlaunching (void) "([email protected]@ @UAE_NXZ) is referenced </span >

Workaround: Add the two files you just generated to the Liblua project and regenerate the Liblua project. It's done!!

4: Call our class in Lua code.

In Hello2.lua's main (), add:

<span style= "FONT-FAMILY:KAITI_GB2312;FONT-SIZE:14PX;" >local test = Myclass:create () print ("The first Cocos bind Lua result".) Test:foo (2)) </span>

Found out the answer we asked for. This completes the Cocos custom class binding to Lua.
