[Using the current latest version] HybridCLR6.9.0+YooAsset2.2.4 to implement a pure C# Unity hot update solution (1)

1. Preface

1. What is a hot update
   Instead of re-downloading the client and installing it when a game or software is updated, resource or code updates are made internally while the application is launched.
2. Unity's current hot update solution
   HybridCLR, Xlua, ILRuntime, etc.
3. Unity's current common resource management solutions
   AssetBundles, Addressable, YooAsset, etc.

Here we use HybridCLR + YooAsset solution for hot update
(Addressable program resource management is not recommended, I personally feel that the pit is more than a billion points)

2.Create development environment

Using VS2022 here, Unity editor version 2022.3.20f1cf1

3. Install HybridCLR

1. First you need to install Windows Build Support (IL2CPP) for the editor in Unity Hub
   
   
2. In the main menu, click Window/Package Manager/+/Add packages from git URLs.
   (of a form etc) fill in/focus-creative-games/hybridclr_unity.git
   
   
3. Create three folders "Scenes", "Scripts" and "YooAssset" in the Assets directory.
   
4. Create a Main screen in the Scenes folder (right click/create/scene) and double click to open it
5. Create an empty object in the scene
   
6. Then create the file in the Scripts folder(Used to output logs)

using ;
using UnityEngine;

public class ConsoleToScreen : MonoBehaviour
{
    const int maxLines = 50;
    const int maxLineLength = 120;
    private string _logStr = "";

    private readonly List<string> _lines = new();

    public int fontSize = 15;

    void OnEnable() {  += Log; }
    void OnDisable() {  -= Log; }

    public void Log(string logString, string stackTrace, LogType type)
    {
        foreach (var line in ('\n'))
        {
            if ( <= maxLineLength)
            {
                _lines.Add(line);
                continue;
            }
            var lineCount =  / maxLineLength + 1;
            for (int i = 0; i < lineCount; i++)
            {
                if ((i + 1) * maxLineLength <= )
                {
                    _lines.Add((i * maxLineLength, maxLineLength));
                }
                else
                {
                    _lines.Add((i * maxLineLength,  - i * maxLineLength));
                }
            }
        }
        if (_lines.Count > maxLines)
        {
            _lines.RemoveRange(0, _lines.Count - maxLines);
        }
        _logStr = ("\n", _lines);
    }

    void OnGUI()
    {
         = (, ,
            new Vector3( / 1200.0f,  / 800.0f, 1.0f));
        (new Rect(10, 10, 800, 370), _logStr, new GUIStyle { fontSize = 10 });
    }
}

7. will be mounted on the newly created empty object
8. In the Scripts folder createHotUpdatefile (paper)
