Lua_ uLua_C#中使用Lua_016

前期工作，导入ulua_v1.25.unitypackage，然后在工程中引入LuaInterface命名空间。

---

方法一：

using LuaInterface;// 常见一个Lua解释器LuaState lua = new LuaState();//创建全局变量 "num" and "str"lua["num"] = 2;lua["str"] = "a string";//创建空表lua.NewTable("table_one");LuaTable tb = lua.GetTable("table_one");tb["a"]=1000;print(tb["a"]);// Read global variables "num" and "str"double num = (double)lua["num"];string str = (string)lua["str"];

---

方法二：

DoString 和DoFile方法可以执行Lua脚本，方法返回一个脚本执行后返回的数组

// Execute a Lua script filelua.DoFile("script.lua");// Execute chunks of Lua codelua.DoString("num=2");lua.DoString("str=’a string’");// Lua code returning valuesobject[] retVals = lua.DoString("return num,str");

• DoString

using UnityEngine;using System.Collections;using LuaInterface;public class HelloWorld : MonoBehaviour {    // Use this for initialization    void Start () {        LuaState l = new LuaState();        string str = "print('hello world 世界')";        l.DoString(str);    }}using UnityEngine;using System.Collections;using LuaInterface;public class ScriptsFromFile_01 : MonoBehaviour{    public TextAsset scriptFile;    // Use this for initialization    void Start()    {        LuaState l = new LuaState();        l.DoString(scriptFile.text);    }}

• DoFile

using UnityEngine;using System.Collections;using LuaInterface;public class ScriptsFromFile_02 : MonoBehaviour{    // Use this for initialization    void Start()    {        //只是展示如何加载文件。不是推荐这么做        LuaState l = new LuaState();        string path = Application.dataPath + "/uLua/luaScript.lua";                l.DoFile(path);    }}

参考代码

using System.Collections;using System.Collections.Generic;using UnityEngine;using LuaInterface;public class Test : MonoBehaviour {    // Use this for initialization    void Start()    {        //创建一个Lua的解释器        LuaState lua = new LuaState();        lua["num"] = 34;        Debug.Log(lua["num"]);        //可以直接执行lua的代码        lua.DoString("num=2");        Debug.Log(lua["num"]);        lua.DoString("str='a string'");        Debug.Log(lua["str"]);        object[] values = lua.DoString("return num,str");        foreach (var item in values)        {            Debug.Log(item);        }        //下面这句代码默认的路径是  Application.dataPath +\uLua\Lua + LuaTest.lua        //Util.LuaPath("LuaTest.lua");        //在这里不能直接使用Lua.        string path = Application.dataPath + "/LuaTest.lua";        //执行lua的文件        object[] objs = lua.DoFile(path);    }}

在Lua中调用C#静态方法

编写脚本如下

using System.Collections;using System.Collections.Generic;using UnityEngine;using LuaInterface;public class Test : MonoBehaviour {    // Use this for initialization    void Start()    {        string lua01 = @"Test.MethodTest01()";        LuaScriptMgr luaMgr = new LuaScriptMgr();        luaMgr.Start();        LuaState luastate = luaMgr.lua;        luastate.DoString(lua01);    }    public static void MethodTest01()    {        Debug.Log("Hahahaha");    }}

然后下图中点击Clear LuaBinder file + wrap Files

然后在uLua/Editor目录下面找到WrapFile文件，在binds静态数组中添加_GT(typeof(Test))，最后在上图中选择第二步Gen Lua Wrap Files，运行Unity即可
