slua学习记录(一)

1.导入插件后  Slua/LuaObject文件夹下的文件全部为生成文件，生成方式为菜单中Slua -> All -> Make(每次Make之前最好先Clear一次)
2.unity - lua交互过程中的文件有：unity C#脚本（自写），LuaObject文件夹下的Lua_C#文件名的脚本（生成），对应的lua脚本（自写）
3.若想在lua中调用C#类，需在C#类中加入[CustomLuaClass]或[CustomLuaClassAttribute]属性
如：
[CustomLuaClass]
public class Deleg : MonoBehaviour
4.lua与C#互调并简单交互
如：只需建立一个新场景在场景中添加一个Button（UGUI）,随便给一个游戏对象绑定LzdTest脚本即可运行
（C#）

using UnityEngine;
using System.Collections;
using SLua;
using System;
using LuaInterface;

[CustomLuaClass]
public class LzdTest : MonoBehaviour {
	
	//this is a delegate
	public delegate void LzdTestDelegate(string path, GameObject g);
	static public LzdTestDelegate lzd;

	
	LuaSvr l;
	LuaTable self;
	LuaFunction update;
	void Start()
	{
		l = new LuaSvr();
		l.init(null,()=>{
			self = (LuaTable)l.start("lzdtest");
			update = (LuaFunction)self["update"];
			//C# call lua
			string str = (string)l.luaState.getFunction ("lzdFunc").call ("hello world");
			Debug.Log (str);
		});

	}

	void Update () {
		//call lua “update” function in Update
		if(update!=null) update.call(self);
	}


	static public void callD()
	{
		//call delegate function
		if (lzd != null)
			lzd("GameObject", new GameObject("SimpleDelegate"));
		Debug.Log ("callD");
	}

	//lua call C#
	public void luaCallCS(string wtf)
	{
		Debug.Log (wtf);
	}
}
