using UnityEngine;
using XLua;

[Hotfix]//添加这个标签后，就可以对类中任一方法进行更改
public class HotfixTest : MonoBehaviour
{
LuaEnv luaenv = new LuaEnv();// lua虚拟环境

public int tick = 0; //如果是private的，在lua设置xlua.private_accessible(CS.HotfixTest)后即可访问

// Use this for initialization
void Start()
{

}

// Update is called once per frame
[LuaCallCSharp]//添加标签，在Lua中调用C#
void Update()
{
if (++tick % 50 == 0)
{
Debug.Log(">>>>>>>>Update in C#, tick = " + tick);
}
}

void OnGUI()
{
if (GUI.Button(new Rect(10, 10, 300, 80), "Hotfix"))
{
//对类中某个方法打补丁
//xlua.hotfix（CS.HotfixTest,）//（类名，想要修复的方法，替换代码）
luaenv.DoString(@"
xlua.hotfix(CS.HotfixTest, 'Update', function(self)
--找到主相机，并输出名字    在Update中使用lua调用c#，要在Update上添加标签   [LuaCallCSharp]
local a= CS.UnityEngine.GameObject.Find('Main Camera')
CS.UnityEngine.Debug.Log(a.name)
self.tick = self.tick + 1
if (self.tick % 50) == 0 then
print('<<<<<<<<Update in lua, tick = ' .. self.tick)
end
end)
");
}

string chHint = @"在运行该示例之前，请细致阅读xLua文档，并执行以下步骤：

1.宏定义：添加 HOTFIX_ENABLE 到 ‘Edit > Project Settings > Player > Other Settings > Scripting Define Symbols’。
（注意：各平台需要分别设置）
2.生成代码：执行 ‘XLua > Generate Code’ 菜单，等待Unity编译完成。
3.注入：执行 ‘XLua > Hotfix Inject In Editor’ 菜单。注入成功会打印 ‘hotfix inject finish!’ 或者 ‘had injected!’ 。";
string enHint = @"Read documents carefully before you run this example, then follow the steps below:

1. Define: Add ‘HOTFIX_ENABLE’ to ‘Edit > Project Settings > Player > Other Settings > Scripting Define Symbols’.
   (Note: Each platform needs to set this respectively)
   2.Generate Code: Execute menu ‘XLua > Generate Code’, wait for Unity’s compilation.
   3.Inject: Execute menu ‘XLua > Hotfix Inject In Editor’.There should be ‘hotfix inject finish!’ or ‘had injected!’ print in the Console if the Injection is successful.";
   GUIStyle style = GUI.skin.textArea;
   style.normal.textColor = Color.red;
   style.fontSize = 16;
   GUI.TextArea(new Rect(10, 100, 500, 290), chHint, style);
   GUI.TextArea(new Rect(10, 400, 500, 290), enHint, style);
   }
   }
   1、将Xlua Assets中的内容copy到目标项目的Assets内

2、将XLua内的Tools复制到项目Assets外

3、打开项目，在项目的Build Settings——Other Settings——Scripting Define Symbols填入：HOTFIX_ENABLE

4、将本地Unity目录下的\Editor\Data\Managed下的Unity.Cecil.dll、Unity.Cecil.Mdb.dll、Unity.Cecil.Pdb.dll三个文件复制到项目中的\Assets\XLua\Src\Editor文件夹下

注意：不可将XLua放在中文目录下

5、逐步运行Unity中的XLua—Generate Code、Hotfix Inject In Editor（若第一次未出现，再重复运行一次）.

6、打包发布时，需删掉XLua中的Examples，并且重新运行：XLua—Clear Generated Code—Generate Code—Hotfix Inject In Editor
