ccc 2.2.0 jsb绑定

参考链接：https://www.jianshu.com/p/34260c0c5175

环境版本信息

Mac 10.15.1
Xcode 11.1
Cocos Creator 2.2.0
Python 2.7

一、首先用ccc创建一个hello world工程

快捷键command+shift+b 打开构建面板构建build目录

二、使用xcode打开工程

然后在Classes文件夹中创建c++测试文件

CustomLog.h 代码如下：

#ifndef CustomLog_h
#define CustomLog_h#include <stdio.h>
#include <string.h>class CustomLog{
public:void MLog(const char * msg);static CustomLog* getInstance();CustomLog();~CustomLog();
};
#endif /* CustomLog_h */

CustomLog.cpp 代码如下：

nclude "CustomLog.h"
#include "cocos2d.h"static CustomLog* s_CustomLog = nullptr;
CustomLog::CustomLog(){cocos2d::log("CustomLog");
}
CustomLog::~CustomLog(){cocos2d::log("~CustomLog");
}
CustomLog* CustomLog::getInstance(){if (!s_CustomLog) {s_CustomLog = new CustomLog();}return s_CustomLog;
}
void CustomLog::MLog(const char* msg){cocos2d::log("MLog~~~~~~ = %s",msg);
}

三、生成jsb绑定文件

1、首先将Classes中的Custom文件夹复制到/Applications/CocosCreator.app/Contents/Resources/cocos2d-x中
2、然后进入目录/Applications/CocosCreator.app/Contents/Resources/cocos2d-x/tools/tojs中
复制cocos2dx.ini文件改名为CustomLog.ini
并修改CustomLog.ini中6个key的值为

[CustomLog]
prefix = custom
target_namespace =
headers = %(cocosdir)s/Custom/CustomLog.h
classes = CustomLog
abstract_classes = CustomLog

复制genbindings.py为genbindings_custom.py
并修改genbindings_custom.py中的

cmd_args = {'CustomLog.ini': ('CustomLog', 'jsb_CustomLog_auto')}

3、运行genbindings_custom.py

#进入genbindings_custom.py当前目录cd /Applications/CocosCreator.app/Contents/Resources/cocos2d-x/tools/tojs python genbindings_custom.py

genbindings_custom.py运行可能会缺少库在参考链接中有解决方案

看到

----------------------------------------
Generating javascript bindings succeeds.
----------------------------------------

代表生成绑定成功

四、将生成的绑定文件添加到项目中

在目录/Applications/CocosCreator.app/Contents/Resources/cocos2d-x/cocos/scripting/js-bindings/auto中可以找到
jsb_CustomLog_auto.hpp
jsb_CustomLog_auto.cpp

复制两个文件到Classes/CustomJsb文件夹中

//在AppDelegate.cpp中引入头文件
并在applicationDidFinishLaunching()方法中的jsb_register_all_modules()后调用se->addRegisterCallback(register_all_custom)

//AppDelegate.cpp
#include "CustomJsb/jsb_CustomLog_auto.hpp"
...
bool AppDelegate::applicationDidFinishLaunching(){...jsb_register_all_modules();se->addRegisterCallback(register_all_custom);//添加...
}

最后检查build phases是否存在两个新增cpp文件

android需要配置Android.mk文件
/Users/lewan/Documents/ccc_dir/ccc_test_1/build/jsb-link/frameworks/runtime-src/proj.android-studio/app/jni/Android.mk

LOCAL_SRC_FILES := hellojavascript/main.cpp \../../../Classes/AppDelegate.cpp \../../../Classes/Custom/CustomLog.cpp \../../../Classes/CustomJsb/jsb_CustomLog_auto.cpp \

五、在js中调用

    onLoad: function () {if (cc.sys.isNative) {cc.log('this is native')var m_CustomLog = CustomLog.getInstance();m_CustomLog.MLog("啦啦啦啦啦啦啦啦 js");}}

运行结果：

ios
android
