Unity ToLua 之 C#调用Lua(三)

• ToLua和XLua不同，XLua相当于映射，而ToLua相当于访问（ToLua中对表的操作都是引用）

一.访问List和Dictionary

• 设置LuaTable都是按引用设置

testList1 = {10,20,30,40}
testList2 = {false,"zzs",1,6.6}

testDic1 = {
    ["zzs"] = 1,
    ["wy"] = 22,
    ["pnb"] = 333
}
testDic2 = {
    [true] = "zzs",
    [1] = 88.92,
    ["wy"] = false
}

public class Lesson06_ListDic : MonoBehaviour
{
    private void Start()
    {
        LuaMgr.GetInstance().Init();
        LuaMgr.GetInstance().Require("Main");

        var luaState = LuaMgr.GetInstance().LuaState;
        
        //List映射
        var luaTable1 = luaState.GetTable("testList1");
        Debug.Log(luaTable1[1]);
        foreach (var item in luaTable1.ToArray())
        {
            Debug.Log(item);
        }

        //引用传递
        luaTable1[1] = 999;
        Debug.Log(luaState.GetTable("testList1")[1]);
        
        Debug.Log("====================");
        var luaTable2 = luaState.GetTable("testList2");
        Debug.Log(luaTable2[1]);
        luaTable2[1] = 888.8;
        foreach (var item in luaTable2.ToArray())
        {
            Debug.Log(item);
        }
        
        Debug.Log("======Dic映射======");
        //Dic映射
        var dic1 = luaState.GetTable("testDic1");
        Debug.Log(dic1["zzs"]);
        Debug.Log(dic1["wy"]);
        Debug.Log(dic1["pnb"]);
        var d = dic1.ToDictTable<string, int>();
        foreach (var item in d)
        {
            Debug.Log(item.Key);
            Debug.Log(item.Value);
        }

        var dic2 = luaState.GetTable("testDic2");
        var dd = dic2.ToDictTable<object, object>();
        //引用传递
        dd["wy"] = 3.14;
        foreach (var item in dd)
        {
            Debug.Log(item.Key);
            Debug.Log(item.Value);
        }
    }
}

二.访问类

testClass = {
    age = 18,
    name = "zzs",
    Eat = function ()
        print("我吃东西")
    end
}

public class Lesson07_Class : MonoBehaviour
{
    void Start()
    {
        LuaMgr.GetInstance().Init();
        LuaMgr.GetInstance().Require("Main");
        var luaState = LuaMgr.GetInstance().LuaState;

        var testClass = luaState.GetTable("testClass");
        Debug.Log(testClass["age"]);
        Debug.Log(testClass["name"]);
        var func = testClass.GetLuaFunction("Eat");
        func.Call();
    }
}

三.使用协程

• 使用协程时需要添加LuaLooper脚本，并初始化才能使用协程
• 注意，下面的Lua代码的协程写法是ToLua为其提供的正常的Lua和XLua不能这么写

local cor = nil

StartDelay = function()
    cor = coroutine.start(Delay)
end

Delay = function()
    local a = 1
    while true do
        print(a)
        coroutine.wait(1)
        a = a + 1
        if a > 5 then
            StopDelay()
            break
        end
    end
end

StopDelay = function()
    coroutine.stop(cor)
end

public class Lesson08_Coroutine : MonoBehaviour
{
    private void Start()
    {
        LuaMgr.GetInstance().Init();
        LuaMgr.GetInstance().Require("Main");
        var luaState = LuaMgr.GetInstance().LuaState;

        var func = luaState.GetFunction("StartDelay");
        func.Call();
    }
}
