XLua implements hot update

In the process of game development, there are often updates, and the small version does not need to be re-downloaded when it is updated, so as to better protect the player's experience. Here we use our hot update technology

Only learning is recorded here, and simple function updates are completed

Here you need to import an XLua plugin

To use hot update, you need to modify the settings here

Add a command here to allow hot update operations as follows:

The case this time is a game about eating snakes. The hot update adds an operation of clicking the left mouse button and then stopping the right button and vice versa.

Two methods are declared here for hot update. Of course, you can update any method. Hot update will update the content in your method to the content in your hot update method.

 

 Then judge the call in update

You also need to write a class to call Lua

using XLua;
using System.IO;

public class TestSnake : MonoBehaviour
{
    LuaEnv lua;
    // Start is called before the first frame update
    void Start()
    {
        lua = new LuaEnv();
        lua.AddLoader(Loads);
        lua.DoString("require('Snake')");
    }
    byte[] Loads(ref string fileName)
    {
        string path = Application.dataPath + "/Lua/" + fileName + ".lua";
        return File.ReadAllBytes(path);
    }
    // Update is called once per frame
    void OnDestory()
    {
        lua.Dispose();
    }
}

 Next is the hot update of Lua

engine=CS.UnityEngine

xlua.hotfix(CS.Player,'Stop',--你需要更新的方法名
function(self)
     engine.Time.timeScale=0
end
)
xlua.hotfix(CS.Player,'ReStart',
function(self)
     engine.Time.timeScale=1
end
)

 Xlua hot update can cover all the content of the original method after updating

After writing, you need to update it in Unity

First click on the second item to clear, click on the first item to rewrite, and finally click on the third item to update

 This completes the hot update
