C#调用lua

直接拿官方的demo里的脚本作为例子

C#中编译Lua脚本的格式

private string script =
        @" lua脚本";

首先new一个lua

LuaState lua = new LuaState();
        lua.Start();

在C#中执行编译的Lua脚本

lua.DoString("事先编译好的string格式的Lua脚本方式");

获取lua变量

//通过LuaState访问
Debugger.Log("Read var from lua: {0}", lua["var2read"]);
Debugger.Log("Read table var from lua: {0}", lua["varTable.default"]);  //LuaState 拆串式table

调用Lua方法

LuaFunction func = lua["TestFunc"] as LuaFunction;
func.Call();
func.Dispose();

访问LuaTable
lua脚本

            var2read = 42
            varTable = {1,2,3,4,5}
            varTable.default = 1
            varTable.map = {}
            varTable.map.name = 'map'
            
            meta = {name = 'meta'}
            setmetatable(varTable, meta)
            
            function TestFunc(strs)
                print('get func by variable')
            end

C#脚本

        //cache成LuaTable进行访问
        LuaTable table = lua.GetTable("varTable");
        Debugger.Log("Read varTable from lua, default: {0} name: {1}", table["default"], table["map.name"]);
        table["map.name"] = "new";  //table 字符串只能是key
        Debugger.Log("Modify varTable name: {0}", table["map.name"]);

        table.AddTable("newmap");
        LuaTable table1 = (LuaTable)table["newmap"];
        table1["name"] = "table1";
        Debugger.Log("varTable.newmap name: {0}", table1["name"]);
        table1.Dispose();

        table1 = table.GetMetaTable();

        if (table1 != null)
        {
            Debugger.Log("varTable metatable name: {0}", table1["name"]);
        }

        object[] list = table.ToArray();//转成List格式

        for (int i = 0; i < list.Length; i++)
        {
            Debugger.Log("varTable[{0}], is {1}", i, list[i]);
        }

        table.Dispose();                        
        lua.CheckTop();
        lua.Dispose();
