XLua学习笔记：fish.lua修改Unity内的Treasour.cs脚本

 unity调用外部的fish.lua文件

using System.Collections;
using System.Collections.Generic;
using System.IO;
using UnityEngine;
using XLua;
public class HotFixScripts : MonoBehaviour
{
    private LuaEnv luaEnv;
	void Start () {
		luaEnv=new LuaEnv();
        luaEnv.AddLoader(MyLoadder);
	    luaEnv.DoString("require'fish'");
	}
	void Update () {
		
	}

    private byte[] MyLoadder(ref string Filepath)
    {
        string absPath = @"F:\MyWork\Project\XluaProjects\PlayerGamePackage\" + Filepath+".lua.txt";
        return System.Text.Encoding.UTF8.GetBytes(File.ReadAllText(absPath));
    }

    void OnDisable()
    {
        luaEnv.DoString("require'fishDispose'");
    }

    void OnDestroy()
    {
        luaEnv.Dispose();
    }
}

 fish.lua 修改Unity内的Treasour.cs内的CreatePrize方法

--1.1
local UnityEngine=CS.UnityEngine
xlua.hotfix(CS.Treasour,'CreatePrize',function(self)
    for i=0,4,1 do
        local go=UnityEngine.GameObject.Instantiate(self.gold, self.transform.position + UnityEngine.Vector3(-10+ i * 30, 0, 0), self.transform.rotation);
		go.transform.SetParent(go.transform,self.cavas)
		local go1=UnityEngine.GameObject.Instantiate(self.diamands, self.transform.position + UnityEngine.Vector3(0, 30, 0)+UnityEngine.Vector3(-10+ i * 40, 0, 0), self.transform.rotation);
		go1.transform.SetParent(go1.transform,self.cavas)
    end
end)

fishDispose.lua 释放Xlua

xlua.hotfix(CS.Treasour,'CreatePrize',nil)

被修改的Treasour.cs(类要添加[HotFix],修改的方法要添加  [LuaCallCSharp])
