cocos2dx3.x lua绑定

参考:http://www.it165.net/pro/html/201410/23367.html

On Windows:

------------


* Make sure that you have installed `android-ndk-r9b`.
* Download python2.7.3 (32bit) from (http://www.python.org/ftp/python/2.7.3/python-2.7.3.msi).
* Add the installed path of python (e.g. C:\Python27) to windows environment variable named 'PATH'.
* Download pyyaml from http://pyyaml.org/download/pyyaml/PyYAML-3.10.win32-py2.7.exe and install it.
* Download pyCheetah from https://raw.github.com/dumganhar/my_old_cocos2d-x_backup/download/downloads/Cheetah.zip, unzip it to "C:\Python27\Lib\site-packages"
* Set environment variables (`NDK_ROOT`)

* Go to "cocos2d-x/tools/tolua" folder, and run "genbindings.py". The generated codes will be under "cocos\scripting\auto-generated\js-bindings".

配置环境先

要有ndk,python(python注意下载32位的 我就是原来用64位的没下载32位 导致绑定不成功)

改写python脚本

#!/usr/bin/python

# This script is used to generate luabinding glue codes.
# Android ndk version must be ndk-r9b.

改一下生成文件的输出路径,改下ini文件目录

接下来要自己编写一个ini文件

随便找一个ini文件复制下来

我是用cocos2dx_spine.ini修改的命名为genbindings_myclass.py

注意修改几处

第一行,

prefix

target_namespace

headers   ---->要绑定的文件 我是放在 E:\cocos2d-x-3.6\cocos\userluaband

classes

skip

abstract_class

好了修改好以后就可以在E:\cocos2d-x-3.6\tools\tolua目录下 命令行执行genbindings_myclass.py文件

会在E:\cocos2d-x-3.6\cocos\userluaband\auto 这个路径下生成相应的文件  lua  hpp  cpp
