预览

将.lua文件编译为.luac所涉及到的加密方法

环境配置

如果是cocos2d-x V3.3 或者更高级的版本,你需要配置cocos consol(请查看https://github.com/cocos2d/cocos2d-x/blob/v3/README.md)

如果版本是cocos2d-x V2.2.6,你应该安装Python,然后设置Python的环境变量.

使用方法

如果是cocos2d-x V3.3 或者更高级的版本,在终端里输入cocos luacompile [arguments]

如果版本是cocos2d-x V2.2.6,在终端里，首先cd进目录tools/cocos2d-console/console,然后输入./cocos2d.py luacompile [arguments].

可用的参数（在终端里）

参数	参数的值	例子	描述	是否必须
-h,--help	-	Show the help message and exit	no
-v,--verbose	verbose output	-s,--src	source directory	./projects/MyLuaGame/src	Specify source directory of lua files needed to be compiled,support mutiple source directory	yes
-d,--dst	destination directory	./projects/MyLuaGame/dst	Specify destination directory which bytecode files to be stored.	-e,--encrypt	bool	True	Whether or not to encrypt lua files.	-k,--encryptkey	any string	MyLuaKey	Specify the encrypt key for encrypting lua scripts. It's only take effect when-e,--encryptis enabled. Default value is2dxLua.	-b,--encryptsign	MyLuaSign	Specify the encrypt sign for encrypting lua scripts. It's only take effect when--encryptis enabled. Default value isXXTEA.	--disable-compile	Whether or not to compile lua scripts	no

例子

使用luacompile时，有以下几种方式

方式

cocos2d-x 版本	描述
cocos luacompile -h	cocos2d-x V3.3 or higher version	Show the help message
cocos luacompile -s src_dir -d dst_dir	Precompile the Lua files in thesrc_dirdirectory to bytecode files whichluajitsupports,then store them in the dst_dir directory by the same directory structure.
cocos luacompile -s src_dir -d dst_dir -e True	xxtea.Thekeyandsignfor encrypting are2dxLuaandXXTEAby default. By adding-k xxx -b xxx' to the command,developers can change thekeyandsign,-k xxxset the key value and-b xxx` set the sign value. The encrypted files are stored in the dst_dir directory by the same directory structure.
cocos luacompile -s src_dir -d dst_dir -e True --disable-compile True	Encrypt the Lua files in thesrc_dirbyxxtea,then store them in the dst_dir directory by the same directory structure. Theset the key value and-b xxx` set the sign value. This command is mainly used to make a set of encrypted files run both 32bit and 64bit iOS devices at the same time. Because Apple demand new app must support 64bit,but the stable luajit doesn't support the arm64bit,so providing this command to encrypt the lua files directly.
./cocos2d.py luacompile -h	cocos2d-x V2.2.6	./cocos2d.py luacompile -s src_dir -d dst_dir	./cocos2d.py luacompile -s src_dir -d dst_dir -e True	xxtea.TThe ./cocos2d.py luacompile -s src_dir -d dst_dir -e True --disable-compile True	XXTEAby default,by addingset the key value and-b xxx` set the sign value. This command is mainly used to make a set of encrypted files run both 32bit and 64bit iOS devices at the same time.

注意: 如果在游戏里使用了xxtea加密，你必须调用在c++代码里，调用LuaStack里的setXXTEAKeyAndSign方法以设置key和sign来解密文件。
