Unity--解析ET6接入ILRuntime实现热更

发布时间:2023年12月19日

前言

1.介绍

ILRuntime项目为基于C#的平台(例如Unity)提供了一个纯C#实现,快速、方便且可靠的IL运行时,使得能够在不支持JIT的硬件环境(如iOS)能够实现代码的热更新。学习交流聚集地

介绍 — ILRuntime (http://ourpalm.github.io)

https://ourpalm.github.io/ILRuntime/public/v1/guide/index.html

ET是一个开源的游戏客户端(基于unity3d)服务端双端框架,服务端是使用C# .net core开发的分布式游戏服务端,其特点是开发效率高,性能强,双端共享逻辑代码,客户端服务端热更机制完善,同时支持可靠udp tcp websocket协议,支持服务端3D recast寻路等等 。

2.接入ILRuntime

1.BuildAssemblieEditor.cs

构建codes.dll和codes.pdb到unity工程中并打上ab标签

2.CodeLoader.cs

初始化ILRuntime并启动热更层开始函数

case Define.CodeMode_ILRuntime:
				{

					Dictionary<string, UnityEngine.Object> dictionary = AssetsBundleHelper.LoadBundle("code.unity3d");
					byte[] assBytes = ((TextAsset)dictionary["Code.dll"]).bytes;
					byte[] pdbBytes = ((TextAsset)dictionary["Code.pdb"]).bytes;
				
					AppDomain appDomain = new AppDomain();
					MemoryStream assStream = new MemoryStream(assBytes);
					MemoryStream pdbStream = new MemoryStream(pdbBytes);
					//ILRuntime加载程序集
					appDomain.LoadAssembly(assStream, pdbStream, new ILRuntime.Mono.Cecil.Pdb.PdbReaderProvider());
					//注册委托适配器等
					ILHelper.InitILRuntime(appDomain);
					//缓存所有热更反射类型
					this.allTypes = appDomain.LoadedTypes.Values.Select(x => x.ReflectionType).ToArray();
					//调用到热更层的entry类的start方法
					IStaticMethod start = new ILStaticMethod(appDomain, "ET.Entry", "Start", 0);
					start.Run();
					break;
				}

3.ILHelper.cs
