加密：
在自定义的PostProcessBundles方法中，对复制到ServerData的bundle进行读取，然后加密后写入覆盖。
//加密 byte[] datas = File.ReadAllBytes(targetPath); File.WriteAllBytes(targetPath, AES.AESEncrypt(datas, KEY));
解密：
在自定义的AssetBundleProvider中的BeginOperation，所有的bundle的加载都先拿到byte数组先，不能直接用AssetBundle.LoadFromFile什么的了。
第三个网络下载的，后面会走第二个缓存bundle的逻辑。
private void BeginOperation()
{
string path = m_ProvideHandle.Location.InternalId;
var url = m_ProvideHandle.ResourceManager.TransformInternalId(m_ProvideHandle.Location);
string bundleName = Path.GetFileName(url);
// if a path starts with jar:file, it is an android embeded resource. The resource is a local file but cannot be accessed by
// FileStream(called in LoadWithDataProc) directly
// Need to use webrequest's async call to get the content.
if (AssetBundleManager.Instance.buildInData != null && AssetBundleManager.Instance.buildInData.BuildInBundleNames.Contains(bundleName))//本地资源
{
string streamPath = UnityEngine.AddressableAssets.Addressables.RuntimePath + "/" + PlatformMappingService.GetPlatformPathSubFolder() + "/" + bundleName;

Debug.Log("LoadTwo:" + cachePath);

}需要准备：
一、将lua-protobuf的pb.h和pb.c替换tolua_runtime根目录的pb.c
二、打开pb.c替换luaop_pb函数
LUALIB_API int luaopen_pb(lua_State *L) {
luaL_Reg libs[] = {
{ "pack", Lbuf_pack },
{ "unpack", Lslice_unpack },
#define ENTRY(name) { #name, Lpb_##name } ENTRY(clear),
ENTRY(load),
ENTRY(loadfile),
ENTRY(encode),
ENTRY(decode),
ENTRY(types),
ENTRY(fields),
ENTRY(type),
ENTRY(field),
ENTRY(typefmt),
ENTRY(enum),
ENTRY(defaults),
ENTRY(hook),
ENTRY(tohex),
ENTRY(result),
ENTRY(option),
ENTRY(state),
#undef ENTRY { NULL, NULL }
};
luaL_Reg meta[] = {
{ "__gc", Lpb_delete },
{ "setdefault", Lpb_state },
{ NULL, NULL }
};
if (luaL_newmetatable(L, PB_STATE)) {
luaL_setfuncs(L, meta, 0);
lua_pushvalue(L, -1);
lua_setfield(L, -2, "__index");
}
#if LUA_VERSION_NUM < 502 luaL_register(L, "pb", libs);
#else luaL_newlib(L, libs);
#endif
return 1;
}三、编译
打开msys2 32编译环境 cd到tolua_runtime位置
./build_win32.sh 编译win的tolua.dll，目录在Plugins/x86下
打开编辑android相关的(build_arm.sh、build_x86.sh、link_arm64.bat)，把NDK路径改为本电脑路径，我用的版本是android-ndk-r10e-windows-x86_64，然后在msys2 的32位下执行 ./build_arm.sh，执行./build_x86.sh。编译后的tolua.so在Plugins/Android下
arm64的参考上面步骤，使用msys2 64编译环境
ios和mac没试，需要MAC系统，没条件的可以搞虚拟机弄弄，用终端直接执行相关脚本。
四、库的使用
1.在Unity中找到LuaDLL.cs，找到lua_open_pb位置，替换代码
/* ** third party library */ [DllImport(LUADLL, CallingConvention = CallingConvention.Cdecl)] public static extern int luaopen_pb(IntPtr L); [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);
2.在你创建虚拟机的地方添加打开Lib
// m_LuaState 为 LuaState 对象 m_LuaState.OpenLibs(LuaDLL.luaopen_pb_io); m_LuaState.OpenLibs(LuaDLL.luaopen_pb_conv); m_LuaState.OpenLibs(LuaDLL.luaopen_pb_buffer); m_LuaState.OpenLibs(LuaDLL.luaopen_pb_slice);
3.复制lua-protobuf的protoc.lua和serpent.lua到你的lua脚本目录
今天遇到一个让人哭笑不得的问题，就是我在lua中调用Physics.OverlapSphereNonAlloc一直都检测不到范围内的Collider物体，缓冲的数组也有10的大小，不可能说获取不到的。后面想了想，那应该就是生成Wrap有问题了，结果一看
[MonoPInvokeCallbackAttribute(typeof(LuaCSFunction))]
static int OverlapSphereNonAlloc(IntPtr L)
{
try
{
int count = LuaDLL.lua_gettop(L);
if (count == 3)
{
UnityEngine.Vector3 arg0 = ToLua.ToVector3(L, 1);
float arg1 = (float)LuaDLL.luaL_checknumber(L, 2);
UnityEngine.Collider[] arg2 = null;
int o = UnityEngine.Physics.OverlapSphereNonAlloc(arg0, arg1, arg2);
LuaDLL.lua_pushinteger(L, o);
return 1;
}
else
{
return LuaDLL.luaL_throw(L, "invalid arguments to method: UnityEngine.Physics.OverlapSphereNonAlloc");
}
}
catch (Exception e)
{
return LuaDLL.toluaL_exception(L, e);
}
}哈哈哈，它把缓冲数组直接传null了，并不是我传过来的数组，改成这样就好了
UnityEngine.Collider[] arg2 = ToLua.CheckObjectArray<UnityEngine.Collider>(L, 3);
function Exist2(v)
return v == 2
end
function IsEven(v)
return v % 2 == 0
end
function NotExist(v)
return false
end
function Compare(a, b)
if a > b then
return 1
elseif a == b then
return 0
else
return -1
end
end
function Test(list, list1) list为List<int>,数据1,2,4
list:Add(123)
print('Add result: list[0] is '..list[0]) --123

local count = list.Count
list:Sort(System.Comparison_int(Compare))
print('--------------sort list over----------------------')
for i = 0, count - 1 do

end
list:Clear()
print('list Clear not count is '..list.Count)
end
function Test()
local str = System.String.New('男儿当自强A')
local index = str:IndexOfAny('儿自')
print('and index is: '..index) --1
local buffer = str:ToCharArray()

local luastr = tolua.tolstring(buffer)
print('lua string is: '..luastr..' type is: '..type(luastr)) --string

end
local utf8 = utf8
function Test()

end
local s1 = '天下风云出我辈风云'
print('风云 count is: '..utf8.count(s1, '风云')) --计算风云在字符串中的个数
s1 = s1:gsub('风云', '風雲') --替换并返回整个串
print(s1)
end
local json = require 'cjson' --用cjson库 function Test(str) local data = json.decode(str) --解析json print(data.glossary.title) s = json.encode(data) --序列化为json print(s) end
local num1 = int64.new('789545665421245')
local num = int64.new(201,1) --第一个参数为低32位，第二个参数为高32位
local l,h = int64.tonum2(num1) --转化为低高位的表达方式
local n = int64.new(123,0) --123
local m = int64.new(123,0) --123
if int64.equals(n,123) then --int64和数值对比
print(tostring(n))
end
if n==m then --int64和int64对比
print(tostring(m))
end
using UnityEngine;
using LuaInterface;
public class TestOutArg : MonoBehaviour
{
string script =
@"
function TestPick(pos)
local camera = UnityEngine.Camera.main
local ray = camera:ScreenPointToRay(pos)
local _layer = 2 ^ LayerMask.NameToLayer('Default')
local flag, hit = UnityEngine.Physics.Raycast(ray, nil, 5000, _layer)
if flag then
print('pick from lua, point: '..tostring(hit.point))
end
end
";
LuaState state = null;
LuaFunction func = null;
void Start ()
{
new LuaResLoader();
state = new LuaState();
LuaBinder.Bind(state);
state.Start();
state.DoString(script, "TestOutArg.cs");
func = state.GetFunction("TestPick");
}
void Update()
{
if (Input.GetMouseButtonDown(0))
{
func.BeginPCall();
func.Push(Input.mousePosition);
func.PCall();
func.EndPCall();
}
state.CheckTop();
state.Collect();
}
void OnDestroy()
{
func.Dispose();
func = null;
state.Dispose();
state = null;
}
}涉及out参数的，直接传nil，它会以返回值的形式返回，注意第一个返回值为状态，第二个开始才是out的返回值
ToLua中有一个LuaFileUtils.cs负责去哪里寻找lua文件，然后读取里面的bytes内容。当出现一些不同的加载方式想自定义，就可以创建一个Loader然后继承LuaFileUtils，重写里面的方法。
using UnityEngine;
using System.Collections;
using System.IO;
using LuaInterface;
public class LuaLoader : LuaFileUtils {
// Use this for initialization
public LuaLoader(bool isZip = false) {
instance = this;//外面只要new就好了，单例模式的实例为当前实例了
beZip = isZip;
}
public void AddBundle(string bundleName) {
string url = "";
#if !UNITY_EDITOR
url = LuaConst.luaResDir + "/" + bundleName.ToLower();
#else
url = LuaConst.luaWinTestResDir + "/" + bundleName.ToLower();
#endif
if (File.Exists(url)) {
AssetBundle bundle = AssetBundle.LoadFromFile(url);
if (bundle != null)
{
bundleName = bundleName.Replace("lua/", "").Replace(".mp", "");
base.AddSearchBundle(bundleName.ToLower(), bundle);
}
}
}
public override byte[] ReadFile(string fileName) {
//怎么读取，可以自己重写
return base.ReadFile(fileName);
}
}使用方法就是在你的LuaManager中，初始化new一个自定义的LuaLoder就可以了。
