Unity3d腾讯手游热更新方案Xlua编程

上次简单写了下XLua自定义Load

本文接着上一篇文章内容全面介绍Unity3d下的XLua编程

加载Lua

using System.Collections;using System.Text;using System.Collections.Generic;using UnityEngine;using XLua;public class LoadLua : MonoBehaviour{    //创建XLUA虚拟机（最好创建一个虚拟机，多的话容易耗费性能）    private LuaEnv luaEnv;void Start ()    {        luaEnv = new LuaEnv();        //读取lua内容        luaEnv.DoString("print('HelloWord!')");        //读取lua文件（文件内容是lua脚本）        //其实require是调用一个个Loader（优先加载自定义Loader）        //有一个Loader加载成功将不再停止加载        //以下require执行的Loader是在Resources文件夹读取并执行Loader.lua        luaEnv.DoString("require 'LoadLua'");        //自定义Loader        luaEnv.AddLoader((ref string str) => {            Debug.Log("自定义Loader参数为:" + str);            return Encoding.UTF8.GetBytes("return 'HelloLoader!'");        });        luaEnv.DoString("print ( require '参数')");    }void Update ()    {        if (luaEnv != null)        {            luaEnv.Tick();        }}    private void OnDestroy()    {        //释放        luaEnv.Dispose();    }}

C#调用Lua

using System.Collections;using System.Collections.Generic;using UnityEngine;using XLua;public class CSharpCallLua : MonoBehaviour{    private LuaEnv luaEnv;    private class Table    {        public int table_intiger { get; set; }    }    [CSharpCallLua]    private interface ITable    {        int table_intiger { get; set; }        int fun(object a);    }void Start ()    {        luaEnv = new LuaEnv();        luaEnv.DoString("require('CSharpCallLua')");        //获取类型值        int intiger = luaEnv.Global.Get<int>("intiger");        string str = luaEnv.Global.Get<string>("str");        bool boolean = luaEnv.Global.Get<bool>("boolean");        Debug.Log("取得类型:" + intiger.ToString() + " " + str + " " + boolean.ToString());        //获取表        //类映射        Table tableClass = luaEnv.Global.Get<Table>("table");        Debug.Log("通过类获取:"+tableClass.table_intiger);        //Dictionary映射        Dictionary<string, object> tableDict = luaEnv.Global.Get<Dictionary<string, object>>("table");        Debug.Log("通过Dictionary容器获取:" + tableDict["table_intiger"]);        //List映射        List<int> tableList = luaEnv.Global.Get<List<int>>("table");        Debug.Log("通过List容器获取:" + tableList.Count);        //LuaTable映射        LuaTable luaTable = luaEnv.Global.Get<LuaTable>("table");        Debug.Log("通过LuaTable获取:" + luaTable.Get<int>("table_intiger"));        //接口映射(注：该方法需要加上CSharpCallLua标签)        ITable iTable = luaEnv.Global.Get<ITable>("table");        Debug.Log("通过接口获取:" + iTable.table_intiger);        Debug.Log("通过接口获取的函数返回值:" + iTable.fun(20));    }    void Update ()    {         if(luaEnv!=null)        {            luaEnv.Tick();        }}    private void OnDestroy()    {        if (luaEnv != null)        {            luaEnv.Dispose();        }    }}
