Unity tolua调用C#中的自定义对象的方法

Unity：

定义一个类

 

using UnityEngine;

public class TestLua_A
{
    public int a = 1;

    public void TestFuncStr(string str)
    {
        Debug.Log("mStr :" + str);
    }

    public TestLua_A TestFuc(int a)
    {
        return new TestLua_A() { a = a,};
    }
}

wrap方法：

 

using System;
using LuaInterface;


public class TestLua_AWrap
{
    public static void Register(LuaState L)
    {
        L.BeginClass(typeof(TestLua_A), typeof(Object));
        L.RegFunction("TestFuncStr", TestFuncStr);
        L.RegFunction("New", _CreateTestLua_A);
        L.RegVar("a",get_a,set_a);
        L.EndClass();
    }

    [MonoPInvokeCallback(typeof(LuaCSFunction))]
    static int get_a(IntPtr L)
    {
        object o = null;
        try
        {
            o = ToLua.ToObject(L, 1);
            TestLua_A obj = (TestLua_A)o;
            int ret = obj.a;
            LuaDLL.lua_pushinteger(L, ret);
            return 1;
        }
        catch (Exception e)
        {
            return LuaDLL.toluaL_exception(L, e, o, "attempt to index text on a nil value");
        }
    }

    [MonoPInvokeCallback(typeof(LuaCSFunction))]
    static int set_a(IntPtr L)
    {
        object o = null;
        try
        {
            o = ToLua.ToObject(L, 1);
            TestLua_A obj = (TestLua_A)o;
            int arg0 = ToLua.CheckValue<int>(L, 2);
            obj.a = arg0;
            return 0;
        }
        catch (Exception e)
        {
            return LuaDLL.toluaL_exception(L, e, o, "attempt to index text on a nil value");
        }
        
    }
    [MonoPInvokeCallback(typeof(LuaCSFunction))]
    static int TestFuncStr(IntPtr L)
    {
        try
        {
            int count = LuaDLL.lua_gettop(L);
            TestLua_A obj = (TestLua_A)ToLua.CheckObject<TestLua_A>(L,1);
            string arg0 = ToLua.ToString(L,2);
            obj.TestFuncStr(arg0);
            return 0;
        }
        catch (Exception e)
        {
            return LuaDLL.toluaL_exception(L, e);
        }
    }

    [MonoPInvokeCallback(typeof(LuaCSFunction))]
    static int _CreateTestLua_A(IntPtr L)
    {
        try
        {
            int count = LuaDLL.lua_gettop(L);
            TestLua_A obj = new TestLua_A();
            ToLua.PushSealed(L,obj);
            return 1;
        }
        catch (Exception e)
        {
            return LuaDLL.toluaL_exception(L, e);
        }
    }
}

 

 

Mono:

 

using UnityEngine;
using System.Collections;
using LuaInterface;

public class Test : MonoBehaviour
{
    LuaState lua;


    LuaFunction luaFun;
    // Use this for initialization
    void Start()
    {
        TestLua_A []testLua_A = new TestLua_A[1];
        testLua_A[0] = new TestLua_A();
        lua = new LuaState();
        lua.Start();
        LuaBinder.Bind(lua);
        Blind(lua);
        lua.DoFile(Application.streamingAssetsPath + "/TestLua/test_lua_button.lua");

        luaFun = lua.GetFunction("test_array");
        luaFun.BeginPCall();
        luaFun.Push(testLua_A);
        luaFun.PCall();
        Debug.Log(((TestLua_A)luaFun.CheckObject(typeof(TestLua_A))).a);
        luaFun.EndPCall();

    }

    private void OnApplicationQuit()
    {
        if (luaFun != null)
        {
            luaFun.Dispose();
            luaFun = null;
        }
        lua.Dispose();
    }

    void Blind(LuaState lua)
    {
        lua.BeginModule(null);
        TestLua_AWrap.Register(lua);
        lua.EndModule();
    }
}

  lua 脚本

local TestLua_A = TestLua_A
function test_array( arr )
    -- body
    print(arr[0].a)
    arr[0]:TestFuncStr("asfadsf")
    tmp = TestLua_A:New()
    tmp.a = 600
    return tmp
end
