cocos creator 2.4.7字段绑定jsb mac版本

自动绑定jsb mac版本

第一步：安装pip

Python 版本是2.7

运行》

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py > get-pip.py

sudo python get-pip.py

sudo easy_install pip

pip --version

sudo pip install PyYAML

sudo pip install Cheetah

报错： ImportError: No module named clang

解决： pip install clang

报错： sudo pip install Cheetah

解决：使用 pip install Cheetah

命令打开 open ~/.bash_profile

在该文件添加

export NDK_ROOT="/Users/cf/Library/Android/sdk/ndk/19.2.5345600"

export PYTHON_BIN="/usr/bin/python"

添加完成后可能需要重启

第二步：frameworks/cocos2d-x/cocos/

在该目录下新建文件夹test/

ABCJSBBridge.h

ABCJSBBridge.cpp

#include "ABCJSBBridge.h"

        return true;
    }



   int JSBBridge::get_total_num(int a,int b){
        return a + b;
   }

}

#pragma once

#include "base/ccConfig.h"


#ifndef PROJ_ANDROID_STUDIO_ABCJSBBRIDGE_H
#define PROJ_ANDROID_STUDIO_ABCJSBBRIDGE_H
// #define DLLOG(format)    printf(format, ##__VA_ARGS__)

namespace abc
{
    class JSBBridge
    {
    public:
        /**
        * Returns a shared instance of the director.
        * @js _getInstance

        static JSBBridge* getInstance();

        /** @private */
        JSBBridge();
        /** @private */
        ~JSBBridge();
        bool init();

        int get_total_num(int a,int b);

        static int test_add_num(int a);

    };
}

第三步:frameworks/cocos2d-x/tools/tojs

新建文件 genbindings_test.py 仿照 genbindings.py 写

第四步：

执行命令 python genbindings_test.py

即可在该目录下看到

frameworks/cocos2d-x/cocos/scripting/js-bindings/auto/api/jsb_cocos2dx_test_auto_api.js

我们需要的文件

python 复制代码

第五步：

frameworks/cocos2d-x/cocos/Android.mk

第六步：frameworks/runtime-src/Classes/jsb_module_register.cpp

第七步：

在 ts文件直接调用即可（需要生成android.apk）

let a = abc.JSBBridge.test_add_num(1);

let s = abc.JSBBridge.getInstance().get_total_num(1,2);

注意：官方文档内 jsb_boot.js 文件可以忽略，不用操作
