CocosCreator自动化绑定jsb

与之前的[cocos2dx js自定义js-binding][cocos2dx js_js-binding]不同，这次用的是Cocos2dx里的自动绑定技术，更加的简单、高效、规整以及方便得多。

而且之前的手动写文件不能适应更新后的CocosCreator版本的情况。

**环境配置：**

JDK、NDK、SDK、ANT：这些环境变量，当打包成原生平台的时候，已经配置过。

PYTHON：Mac自带有python，一般是python2.7。

等会还会有其他环境配置，主要是在执行genbindings.py的时候，需要配置的环境。等会再说。

当前的CocosCreator环境是1.8.1。版本的不同，会造成一些小的差异，比如1.8.1的jsb\_module\_register.cpp文件是放在runtime-src/Clesses下的，而之前我用的1.5.1版本是放在cocos/scripting/js-bindings/manual下的。

**配置过程：**

先自定义自己的头文件Test.h

//
    //  Test.h
    //  libcocos2d Mac
    //
    //  Created by zhufu on 2018/3/15.
    //
    
    #ifndef Test_h
    #define Test_h
    
    #include <stdio.h>
    
    #endif /* Test_h */
    
    class Test : public Node
    {
    public:
        void test();
    }

再定义Test.cpp文件

//
    //  Test.cpp
    //  libcocos2d Mac
    //
    //  Created by zhufu on 2018/3/15.
    //
    
    #include "Test.h"
    
    
    void Test::test()
    {
        printf("js binding success!!!!\n");
    }

把这两个文件放在以下路径

![20180315175357992][]

之后，进入cocos2d-x/tools/tojs文件夹中，

这里我们也要配置一个.ini文件，配置方式就学着coco2dx\_extension.ini文件来。

![20180315180331035][]

箭头指向的是自己创建的ini文件,里面的内容是：

[cocos2dx_test]
    # the prefix to be added to the generated functions. You might or might not use this in your own
    # templates
    prefix = cocos2dx_test
    
    # create a target namespace (in javascript, this would create some code like the equiv. to `ns = ns || {}`)
    # all classes will be embedded in that namespace
    target_namespace = cc
    
    android_headers = -I%(androidndkdir)s/platforms/android-14/arch-arm/usr/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.8/libs/armeabi-v7a/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.8/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi-v7a/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.9/include
    android_flags = -D_SIZE_T_DEFINED_ 
    
    clang_headers = -I%(clangllvmdir)s/%(clang_include)s 
    clang_flags = -nostdinc -x c++ -std=c++11 -U __SSE__
    
    cocos_headers = -I%(cocosdir)s -I%(cocosdir)s/cocos/editor-support -I%(cocosdir)s/cocos -I%(cocosdir)s/cocos/platform/android -I%(cocosdir)s/external/sources
    
    cocos_flags = -DANDROID
    
    cxxgenerator_headers = 
    
    # extra arguments for clang
    extra_arguments = %(android_headers)s %(clang_headers)s %(cxxgenerator_headers)s %(cocos_headers)s %(android_flags)s %(clang_flags)s %(cocos_flags)s %(extra_flags)s 
    
    # what headers to parse
    headers = %(cocosdir)s/test/Test.h
    
    replace_headers = Test.h::test/Test.h
    
    # what classes to produce code for. You can use regular expressions here. When testing the regular
    # expression, it will be enclosed in "^$", like this: "^Menu*$".
    
    classes = Test
    
    # what should we skip? in the format ClassName::[function function]
    # ClassName is a regular expression, but will be used like this: "^ClassName$" functions are also
    # regular expressions, they will not be surrounded by "^$". If you want to skip a whole class, just
    # add a single "*" as functions. See bellow for several examples. A special class name is "*", which
    # will apply to all class names. This is a convenience wildcard to be able to skip similar named
    # functions from all classes.
    
    skip = 
    
    rename_functions =
    
    rename_classes = 
    
    # for all class names, should we remove something when registering in the target VM?
    remove_prefix = 
    
    # classes for which there will be no "parent" lookup
    classes_have_no_parents = 
    
    # base classes which will be skipped when their sub-classes found them.
    base_classes_to_skip = Ref
    
    # classes that create no constructor
    # Set is special and we will use a hand-written constructor
    abstract_classes = 
    
    classes_need_extend =

文件内容的参数可以参考[http://www.cocoachina.com/bbs/read.php?tid=177904][http_www.cocoachina.com_bbs_read.php_tid_177904]

至于我们配置的.ini文件与原来的cocos2dx\_extension.ini的不同之处，可以两个文件对比查看。

接着，打开genbindings.py文件，增加如下的一行：

![20180315180937095][]

打开终端，cd到genbindings.py文件所在的目录，运行./genbindings.py。

如无意外，并不成功。。。

但是只要一报错，就查看[锦囊][Link 1]，就能逢凶化吉。

记住，只要一报错，就看一下。

直到出现

\----------------------------------------

Generating javascript bindings succeeds.

\----------------------------------------

为止。

这时候在cocos/scripting/js-bindings/auto，出现在jsb\_cocos2dx\_test.cpp。

![20180316093525948][]

最后，我们打开jsb\_module\_register.cpp文件下添加如下代码：

![20180316094303359][]

和

![20180316094458893][]

至此，c++部分完整工作。

之后，写javascript测试：
