Unity HybridCLR 热更工具学习日记（二）

创建一个程序集用来进行热更，在Assets下面创建一个Hot文件夹，在创建一个Assembly Definition命名为Hot（命名是个人习惯）

然后将这个程序集加入到热更设置中HybridCLR - Settings

 在创建一个热更脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class HotFix : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.A))
        {
            GetComponent<Image>().color = Color.black;
        }
        if (Input.GetKeyDown(KeyCode.S))
        {
            GetComponent<Image>().color = Color.blue;
        }
        if (Input.GetKeyDown(KeyCode.D))
        {
            GetComponent<Image>().color = Color.red;
        }
    }
}

然后编译成热更需要的dll文件，HybridCLR - CompileDll - Win64(测试使用的PC平台)

 

 然后创建一个UI场景，写一个测试脚本，挂载到场景中

using System;
using System.Collections;
using System.Collections.Generic;
using System.Reflection;
using UnityEngine;
using UnityEngine.Networking;

public class TestHot : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(load());
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    IEnumerator load()
    {
        var url = "http://0.0.0.0/Hot.dll";
        UnityWebRequest request = UnityWebRequest.Get(url);
        yield return request.SendWebRequest();
        byte[] b = request.downloadHandler.data;
        var ass = Assembly.Load(b);
        Type entryType = ass.GetType("HotFix");
        gameObject.AddComponent(entryType);
    }
}

 最后打包运行：
