做推广网站的去哪能买到有效资料/免费的推广软件下载
1：本文的基础是建立在官方的文档上的，官方文档https://docs.cocos.com/creator/2.4/manual/zh/advanced-topics/jsb-auto-binding.html，由于官方也是引用论坛里别人的连接，所以文档里有些东西是creator旧版本的，但基本思路是一致的，下面主要围绕不同的做说明
2：需要注意点：
（1）下载的python版本必须是32位的2.7版本，下载地址 https://www.python.org/ftp/python/
（2）window环境只需要配置NDK_ROOT的环境变量，PYTHON_BIN是不需要的
3：creator2.4，自己新建的项目是没有tojs文件夹的，但creator的安装目录是有的，这里可以直接把tojs的上一层目录tools拷到项目路径下
4：例子里的有些文件会导入头文件base/CCConsole.h，需要注释掉，新版本已经没这个文件了，注释掉代码不会受影响
// #include "base/CCConsole.h"ABCJSBBridge.cpp文件更改一下：
#include "ABCJSBBridge.h"// include platform specific implement class
// #if (CC_TARGET_PLATFORM == CC_PLATFORM_MAC || CC_TARGET_PLATFORM == CC_PLATFORM_IOS)// #include "ABCJSBBridge-apple.h"
// #define JSBBridgeImpl JSBBridgeApple// #elif (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)// 这里只实现了android的
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) #include "ABCJSBBridge-android.h"
#define JSBBridgeImpl ABCJSBBridge_android#endifnamespace abc
{// singleton stuffstatic JSBBridge *s_SharedJSBBridge = nullptr;JSBBridge::JSBBridge(){DLLOG("Construct JSBBridge %p", this);init();}JSBBridge::~JSBBridge(){DLLOG("Destruct JSBBridge %p", this);s_SharedJSBBridge = nullptr;}JSBBridge* JSBBridge::getInstance(){if (!s_SharedJSBBridge){DLLOG("getInstance JSBBridge ");s_SharedJSBBridge = new (std::nothrow) JSBBridge();CCASSERT(s_SharedJSBBridge, "FATAL: Not enough memory for create JSBBridge");}return s_SharedJSBBridge;}bool JSBBridge::init(void){DLLOG("init JSBBridge ");_impl.reset(new JSBBridgeImpl());return true; // 原来没加上的}void JSBBridge::abcLog(const int level, const std::string& tag, const std::string& msg){_impl->abcLog(level, tag, msg);}
}5：genbindings_test.py文件和以前的已经不一样了，对应的修改如下
try:tojs_root = '%s/tools/tojs' % project_rootoutput_dir = '%s/cocos/scripting/js-bindings/auto' % project_root# cmd_args = {# 'cocos2dx.ini' : ('cocos2d-x', 'jsb_cocos2dx_auto'),# 'cocos2dx_webview.ini': ('webview', 'jsb_webview_auto'),# 'cocos2dx_video.ini': ('video', 'jsb_video_auto'),# 'cocos2dx_audioengine.ini' : ('cocos2dx_audioengine', 'jsb_cocos2dx_audioengine_auto'),# 'cocos2dx_extension.ini' : ('cocos2dx_extension', 'jsb_cocos2dx_extension_auto'),# 'cocos2dx_network.ini' : ('cocos2dx_network', 'jsb_cocos2dx_network_auto'),# 'gfx.ini': ('gfx', 'jsb_gfx_auto'),# 'renderer.ini': ('renderer', 'jsb_renderer_auto'),# 'cocos2dx_spine.ini': ('cocos2dx_spine','jsb_cocos2dx_spine_auto'),# 'cocos2dx_editor_support.ini': ('cocos2dx_editor_support','jsb_cocos2dx_editor_support_auto'),# 'cocos2dx_dragonbones.ini': ('cocos2dx_dragonbones','jsb_cocos2dx_dragonbones_auto'),# 'cocos2dx_particle.ini': ('cocos2dx_particle', 'jsb_cocos2dx_particle_auto')# }target = 'spidermonkey'generator_py = '%s/generator.py' % cxx_generator_root# for key in cmd_args.keys():# args = cmd_args[key]# cfg = '%s/%s' % (tojs_root, key)# print 'Generating bindings for %s...' % (key[:-4])# command = '%s %s %s -s %s -t %s -o %s -n %s' % (python_bin, generator_py, cfg, args[0], target, output_dir, args[1])# print(command)# _run_cmd(command)custom_cmd_args = {'cocos2dx_test.ini': ('cocos2dx_test', 'jsb_cocos2dx_test_auto')}for key in custom_cmd_args.keys():args = custom_cmd_args[key]cfg = '%s/%s' % (tojs_root, key)print 'Generating bindings for %s...' % (key[:-4])command = '%s %s %s -s %s -t %s -o %s -n %s' % (python_bin, generator_py, cfg, args[0], target, output_dir, args[1])print(command)_run_cmd(command)print '----------------------------------------'print 'Generating javascript bindings succeeds.'print '----------------------------------------'7：对应的cocos2dx_test.ini修改，可以对照其他的ini文件修改
[cocos2dx_test]

9： 官方没有给出对应的IABCJSBBridgeImpl的android实现，这里补上
（1）：ABCJSBBridge-android.h文件
#ifndef __CC_ABCJSBBRIDGE_ANDROID_H__
#define __CC_ABCJSBBRIDGE_ANDROID_H__#include "platform/CCPlatformConfig.h"
#if CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID#include "test/CCIABCJSBBridgeIml.h"
#include "base/ccMacros.h"
#include "base/ccTypes.h"
#include <string>
#include <vector>
#include "jni.h"//! @brief Helper class to handle file operations
class CC_DLL ABCJSBBridge_android : public abc::IABCJSBBridgeImpl
{
public:ABCJSBBridge_android();/*** @js NA* @lua NA*/virtual ~ABCJSBBridge_android();void abcLog(const int level, const std::string& tag, const std::string& msg);// void abcLog(const int level, const std::string& tag, ...);
};// end of platform group
/// @}#endif // CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID#endif // __CC_ABCJSBBRIDGE_ANDROID_H__
（2）：ABCJSBBridge-android.cpp文件
#include "platform/CCPlatformConfig.h"
#if CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID// #include "../platform/CCCommon.h" ??
#include "ABCJSBBridge-android.h"
#include <android/log.h>

#include "../platform/CCFileUtils.h"#define LOG_TAG "ABCJSBBridge-android.cpp"
#define LOGD(level,tag, ...) __android_log_print(level,tag,__VA_ARGS__)#include "base/ccMacros.h"
#include "base/ccTypes.h"ABCJSBBridge_android::ABCJSBBridge_android()
{
}ABCJSBBridge_android::~ABCJSBBridge_android()
{
}void ABCJSBBridge_android::abcLog(const int level, const std::string& tag, const std::string& msg) {
// void abcLog(const int level, const std::string& tag, ...) {LOGD(level, tag.c_str(), msg.c_str(), NULL);
}#endif // CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID
10：修改jsb_module_register.cpp文件，需要注意的文件指路径是在build\jsb-default\frameworks\runtime-src\Classes下面
11 ：jsb_boot.js这个文件2.4已经去掉了，abc.JSBBridge = abc.JSBBridge.getInstance();这句代码是非必要的，现在我们可以在js代码里直接调用了
var level = 2;
var msg = "abc"
abc.JSBBridge.getInstance().abcLog(level, 'test', msg);
