tolua集成lua-protobuf库

在tolua基础上,为了方便使用proto3,这里集成了lua-protobuf库!
十分感谢两位开源库的大大,tolua的蒙大和lua-protobuf的Xavier!在两位的github上有q群的联系方式,欢迎加群交流!
有什么问题也可以在我blog下留言!
本文基于win7x64,unity2017.4,tolua当前最新版本,tolua_runtime当前最新版本,lua-protobuf当前最新版本编写

一丶编译tolua库

资源下载:
tolua_runtime
https://github.com/topameng/tolua_runtime
NDK 版本:android-ndk-r10e 默认安装到 D:/android-ndk-r10e
https://dl.google.com/android/repository/android-ndk-r10e-windows-x86_64.zip
配置好的Msys2下载
https://pan.baidu.com/s/1c2JzvDQ
lua-protobuf
https://github.com/starwing/lua-protobuf

正文:
1.将lua-protobuf工程中的pb.c和pb.h拷贝到tolua_runtime根目录,覆盖pb.c
编译各平台dll
https://www.jianshu.com/p/5a35602adef8?utm_campaign=maleskine&utm_content=note&utm_medium=seo_notes&utm_source=recommendation
2.编译后tolua_runtime下的Plugins文件夹拷贝至tolua文件夹下同名覆盖

问题:
1.NDK路径问题
在tolua_runtime中
build_arm.sh
build_arm64.sh
build_x86.sh
link_arm64.bat
中ndk路径需要和你电脑上ndk的目录一致!
2.群友的总结
(感谢 lua-protobuf交流群 - 潜水的小懒猫 么么哒!)
a.在mac上替换tolua.bundle文件时,需要重启unity,不然无法读取pb
b.在编译mac时,会提示i386架构被弃用,需删掉,将不再支持iPhone5以下机型
(如果执行build_osx.sh时提示不在支持32位,请打开macnojit 在build Setting移除i386的支持即可)
c.在发布ios时,要删除tolua目录下的pb.c文件,不然编译不通过
d.如果执行.sh提示权限不足 可以在终端执行:chmod 777 tolua根目录 然后再次执行.sh脚本即可
3.编译工具的一些说明
Msys2下载后,在其根目录有mingw32_shell.bat和mingw64_shell.bat用来分别开启32位和64位 Msys
32位用于执行tolua_runtime中的build_arm.sh、build_win32.sh、build_x86.sh
64位用于执行tolua_runtime中的build_arm64.sh、build_win64.sh
build_ios.sh、build_osx.sh需要在mac 下执行
build_ubuntu.sh需要在linux下执行(不使用linux开发,不要要编译)
4…sh怎么执行?
在各终端(PC用Msys,mac和linux都是自带)进入.sh脚本所在目录 ./xxx.sh
在这里插入图片描述
5.各种.sh执行中的Error
一定要注意,有错误就要修改,要不打出的dll不保证好用!Error的种类有很多,可以参见出错时的日志,大部分都是配置的问题,要是C库有问题,及时联系对应库的作者,验证是否为bug!

二丶tolua接入(编写测试Demo)
资源下载:
tolua
https://github.com/topameng/tolua

正文:
1.将lua-protobuf中的protoc.lua、luaunit.lua和serpent.lua拷贝至tolua工程Assets\ToLua\Lua(tolua自带lua)文件夹下或者Assets\Lua(自己的业务lua)下
2.unity打开tolua工程,在LuaDLL.cs public static extern int luaopen_pb(IntPtr L);这行下添加

		// lua-protobuf >>>>>>>
        [DllImport(LUADLL, CallingConvention = CallingConvention.Cdecl)]
        public static extern int luaopen_pb_io(IntPtr L);

        [DllImport(LUADLL, CallingConvention = CallingConvention.Cdecl)]
        public static extern int luaopen_pb_conv(IntPtr L);

        [DllImport(LUADLL, CallingConvention = CallingConvention.Cdecl)]
        public static extern int luaopen_pb_buffer(IntPtr L);

        [DllImport(LUADLL, CallingConvention = CallingConvention.Cdecl)]
        public static extern int luaopen_pb_slice(IntPtr L);
        // lua-protobuf <<<<<<

3.在Assets\ToLua\Examples\TestLuaProtobuf新建测试目录,在该目录下新建测试场景TestLuaProtobuf,新建测试脚本TestLuaProtobuf.cs挂于MainCamera下
TestLuaProtobuf.cs脚本如下

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using LuaInterface;
using System;

public class TestLuaProtobuf : MonoBehaviour {
    //lua-protobuf 测试用lua脚本
    string script =
        @"
            local pb = require 'pb'
            local protoc = require 'protoc'

            -- load schema from text
            assert(protoc:load[[
               message Phone {
                    optional string name = 1;
                    optional int64  phonenumber = 2;
                }
                message Person
                {
                    optional string name = 1;
                optional int32  age      = 2;
                  optional string address = 3;
                repeated Phone  contacts = 4;
               } ]])

            -- lua table data
            local data = {
               name = 'ilse',
               age  = 18,
               contacts = {
                  { name = 'alice', phonenumber = 12312341234 },
                  { name = 'bob',   phonenumber = 45645674567 }
               }
            }

            -- encode lua table data into binary format in lua string and return
            local bytes = assert(pb.encode('Person', data))
            print(pb.tohex(bytes))

            -- and decode the binary data back into lua table
            local data2 = assert(pb.decode('Person', bytes))
            print(require 'serpent'.block(data2))
        ";

    int bundleCount = int.MaxValue;
    string tips = null;
    LuaState luaState = null;

    bool testAB = false;//是否打包AB加载

    void Start()
    {
#if UNITY_5 || UNITY_2017 || UNITY_2018
        Application.logMessageReceived += ShowTips;

        if (!testAB) 
        {

}

4.各平台测试
pc上
TestLuaProtobuf.cs 脚本中testAB = false,直接运行测试场景TestLuaProtobuf即可,正常输出
在这里插入图片描述
移动端
TestLuaProtobuf.cs 脚本中testAB = true
unity切换至对应平台,例如切换至Android,执行untiy菜单栏 Lua/Build bundle files no jit,等待打包执行完毕,分别在Assets\StreamingAssets下生成对应平台lua AB包,Android、iOS

在这里插入图片描述
添加测试场景,build 安装包即可!
安卓正常结果
