学习项目 void87/InjectFixLearn (github.com)
安装
编译
- Window下打开源码包的Source\VSProj\build_for_unity.bat，UNITY_HOME变量的值修改为指向本机unity安装目录
- 运行build_for_unity.bat
复制
这里对应的是一个Unity工程目录
- IFixToolKit拷贝到Unity项目的Assets同级目录
- Assets/IFix，Assets/Plugins拷贝到Unity项目的Assets下

HelloWorld(编辑器下体验iFix)
1. 模拟有bug的项目
原始Calculator(加和乘都是错的)
namespace IFix.Test { //HelloworldCfg.cs里配置了这个类型 public class Calculator { //修改成正确的逻辑后，打开如下注释，生成的补丁将修正该函数 //[Patch] public int Add(int a, int b) { return a * b; } public int Sub(int a, int b) { return a / b; } } }
配置类HelloworldCfg
using System.Collections.Generic; using IFix; using System; // 1. 配置类必须打[Configure]标签 // 2. 必须放Editor目录 [Configure] public class HelloworldCfg { [IFix] static IEnumerable<Type> hotfix { get { return new List<Type>() { typeof(IFix.Test.Calculator) }; } } }
Helloworld
using UnityEngine; using IFix.Core; using System.IO; using System.Diagnostics; // 跑不同仔细看文档Doc/example.md public class Helloworld : MonoBehaviour { // check and load patchs void Start () { VirtualMachine.Info = (s) => UnityEngine.Debug.Log(s); //try to load patch for Assembly-CSharp.dll var patch = Resources.Load<TextAsset>("Assembly-CSharp.patch"); if (patch != null) { UnityEngine.Debug.Log("loading Assembly-CSharp.patch ..."); var sw = Stopwatch.StartNew(); PatchManager.Load(new MemoryStream(patch.bytes)); UnityEngine.Debug.Log("patch Assembly-CSharp.patch, using " + sw.ElapsedMilliseconds + " ms"); } test(); } //[IFix.Patch] void test() { var calc = new IFix.Test.Calculator(); //test calc.Add UnityEngine.Debug.Log("10 + 9 = " + calc.Add(10, 9)); //test calc.Sub UnityEngine.Debug.Log("10 - 2 = " + calc.Sub(10, 2)); } }
2. 修复Bug
修改后的Calculator(模拟修bug后,生成文件 Assembly-CSharp.patch.bytes)
namespace IFix.Test { //HelloworldCfg.cs里配置了这个类型 public class Calculator { //修改成正确的逻辑后，打开如下注释，生成的补丁将修正该函数 [Patch] public int Add(int a, int b) { return a + b; // return a * b; } public int Sub(int a, int b) { return a / b; } } }
修复bug后,点击
生成 
3. 回滚到有bug的代码,模拟发包(包里有bug)
将代码还原成有bug的代码
namespace IFix.Test { //HelloworldCfg.cs里配置了这个类型 public class Calculator { //修改成正确的逻辑后，打开如下注释，生成的补丁将修正该函数 //[Patch] public int Add(int a, int b) { return a * b; } public int Sub(int a, int b) { return a / b; } }
点击
.一个版本的包只需要点一次
将Assembly-CSharp.patch.bytes拷贝到
启动带有Assembly-CSharp.patch.bytes补丁的代码
各种测试
IFix.Patch 测试
IFix.Patch 支持普通方法
// IFix.Patch支持普通方法 [IFix.Patch] public int Add(int a, int b) { return a * b; }
IFix.Patch 不支持泛型方法
// IFix.Patch 不支持泛型方法 [IFix.Patch] public void GenericMethod<T>(T t) { UnityEngine.Debug.Log("GenericMethod<T>: " + t); }
参考
IFix.Patch 支持普通方法中调用泛型方法
// IFix.Patch 支持普通方法 [IFix.Patch] public int Add(int a, int b) { // IFix.Patch 支持普通方法中调用泛型方法 InnerGenericMethod<string>("arg"); return a * b; } public void InnerGenericMethod<T>(T t) { UnityEngine.Debug.Log("InnerGenericMethod: " + t); }
参考
IFix.Patch 不支持字段
// IFix.Patch 不支持字段 [IFix.Patch] public string TestField = "TestField";
IFix.Patch 支持普通协程
// IFix.Patch 支持普通协程 [IFix.Patch] public IEnumerator PatchEnumerator() { yield return new WaitForSeconds(1); UnityEngine.Debug.Log("Wait 1 Second"); }
IFix.Patch 不支持构造函数
// IFix.Patch 不支持构造函数 [IFix.Patch] public Calculator() { }
参考
IFix.Patch 支持getter,setter函数
private string testField = "testField"; public string TestProperty { [IFix.Patch] get { return testField; } [IFix.Patch] set { testField = value; } }
参考
IFix.Interpret
IFix.Interpret 支持不带泛型方法的新憎类
// IFix.Interpret 支持不带泛型方法的新增类 [IFix.Interpret] public class NewClass { public Action<object> act; public string testField = "TestField"; public NewClass(string cons) { UnityEngine.Debug.Log("NewClass.Constructor"); } }
IFix.Interpret 不支持带泛型方法的新增类
// IFix.Interpret 不支持带泛型方法的新增类 [IFix.Interpret] public class PatchClass { public void PatchGenericMethod<T>(T t) { UnityEngine.Debug.Log(t); } }
IFix.Interpret 支持新增普通方法
// IFix.Interpret 支持新增普通方法 [IFix.Interpret] public void PatchMethod() { UnityEngine.Debug.Log("PatchMethod"); }
参考
IFix.Interpret 不支持新增泛型方法
// IFix.Interpret 不支持新增泛型方法 [IFix.Interpret] public void PatchGenericMethod<T>(T t) { UnityEngine.Debug.Log("PatchGenericMethod"); }
IFix.Interpret 支持新增类继承新增类
[IFix.Interpret] public class PatchBaseClass { public void BaseMethod() { UnityEngine.Debug.Log("BaseMethod"); } } // IFix.Interpret 支持新增类继承新增类 [IFix.Interpret] public class PatchChildClass : PatchBaseClass { public void ChildMethod() { UnityEngine.Debug.Log("ChildMethod"); } }
参考
IFix.Interpret 不支持字段
// IFix.Patch 不支持字段 [IFix.Interpret] public string TestField = "TestField";
参考
IFix.Interpret 不支持构造函数
// IFix.Interpret 不支持构造函数 [IFix.Interpret] public Calculator() { }
IFix.Interpret支持协程,但有限制
// 非热更代码里用过 IEnumerator private IEnumerator IE_Main() { yield return new WaitForEndOfFrame(); Debug.Log("IE_Main"); } [IFix.Interpret] private IEnumerator IE_Patch() { // 非热更代码里用过 IEnumerator, 热更代码里可以使用 yield return new WaitForSeconds(1); yield return new WaitForEndOfFrame(); yield return 0; yield return null; Debug.Log("IE_Patch"); yield break; }
[IFix.Interpret] public IEnumerator IE_Patch() { // 非热更代码里没有用过 IEnumerator, 热更代码里不可以使用 yield return new WaitForSeconds(1); yield return new WaitForEndOfFrame(); yield return 0; yield return null; Debug.Log("IE_Patch"); yield break; }
参考
IFix.Interpret不支持Struct
参考
IFix.CustomBridge
热更代码新增实现非热更代码里的接口时,需要在非热更代码里增加处理, 热更代码目前不支持继承非热更代码里的原生类
using System; using System.Collections; using System.Collections.Generic; using UnityEngine; public class Test : MonoBehaviour { [IFix.Patch] void Start() { PatchClassInheritInterface pcii = new PatchClassInheritInterface(); pcii.TestInterfaceMethod(); //PatchClassInheritClass pcic = new PatchClassInheritClass(); //pcic.TestMethod(); } } // 非热更接口 public interface TestInterface { void TestInterfaceMethod(); } // 热更新增类能继承非热更原生接口 [IFix.Interpret] public class PatchClassInheritInterface : TestInterface { public void TestInterfaceMethod() { UnityEngine.Debug.Log("TestInterfaceMethod"); } } //// 非热更类 //public class TestClass { // public virtual void TestMethod() { // Debug.Log("TestMethod"); // } //} //// 热更新增类不能继承非热更原生类 //[IFix.Interpret] //public class PatchClassInheritClass : TestClass { // public override void TestMethod() { // Debug.Log("TestMethod"); // } //} // 要在非热更代码里提前加上 [IFix.CustomBridge] public static class AdditionalBridge { static List<Type> bridge = new List<Type>() { typeof(TestInterface), // typeof(TestClass) // 目前不支持, 热更新增类继承非热更原生接口 }; }
参考
CustomBridge的新增类只支持interface，不支持class

各种Issue
Close
多个 Assembly Definition 的template file 怎么设置？
添加配置文件，添加python构建脚本用于跨平台构建，添加混淆key支持
Warning: read ./Library/ScriptAssemblies/Assembly-CSharp.dll with symbol fail
执行"InjectFix/Fix"后提示please install the ToolKit
修改源码导出新的dll后，xcode工程导出报错，像是IL2CPP转方法报错了 IFix.Core.EvaluationStackOperation::ToObject
编辑器下除了reimport unity工程，有没有更好的方法回滚Inject了之后的dll
Unhandled Exception:System.Exception: Utils/<ReadBinaryFileAsync>d__0 is CompilerGenerated
The type or namespace name `IFix' could not be found
Exception: instruction magic not match
【优化IFix报错日志】使用debug模式运行ifix.exe，报错日志里包含源码文件和行信息，方便查问题
求增加一个Inject和Fix时的UI效果！提醒用户正在Inject或者Fix中！
【实现建议】不用IDMAP，只使用IDTagAttribute。
Error: the new assembly must not be inject, please reimport the project!
当使用 .net4.x async await来进行异步编程时，inject 阶段报异常
> 我也碰到了类似的问题，最简化代码如下，当注入class A的时候将会报错
Unity2019.2.15f1版本打包出来会出现未注入的情况
Unity2019.3.0f3 没有Editor\Data\Mono\bin\gmcs
UnityEditor热更没问题，打包到Android后Load报错
【BugReport】结构体初始化如果不使用new关键字，会报错
虚函数中如果用关键词in修饰struct类型的参数，inject后执行会报错
Fix 和 inject 时弹出 warnning ，并且在Editor下没有看到效果
当hotfix的代码导致游戏崩溃，几乎无法查找明确的堆栈入口信息或者明确的方法信息
最新版本无法生成IFix.Core.dll和IFix.exe
在编辑器模式下初始化Inject报错因为我使用了linq配置
子类没有override父类的函数，打Interpret标签不会生效
IEnumerator<T>的Current在解释执行下报错
[fixbug] CustomBridge 注入跨dll的delegate，InjectFix 时报错
Unity2019 iOS注入失败，Unity2018 iOS注入成功
CustomBridge属性可以做到自动给程序集的所有Delegate和Interface加上Wrapper吗？
请教 Non-static method requires a target 错误
Open
为什么说：InjectFix在对Unity协程，闭包的支持中其实是包含了对新增class的支持？
无法访问Unity的 Debug.unityLogger.logEnabled 属性
TargetException: Non-static method requires a target
使用了BurstCompile的类和结构体不能进行注入，否则加载patch之后会报burst的错误
2019.3.8再编译build_for_unity.bat时找不到gmcs目录
请教下GetTagMethods与GetTagClasses中assembly.CodeBase.IndexOf("ScriptAssemblies") != -1的用意。
//case Code.Stelem_Any: //0.03166702% 泛型中使用？泛型不支持解析，所以不会碰到这指令（我遇到了这个指令没被实现的异常）
增加方法没参数的情况会抛异常Exception: can not load field[*]
杂项
对程序集里的所有方法Inject
// 1. 配置类必须打[Configure]标签 // 2. 必须放Editor目录 [Configure] public class HelloworldCfg { [IFix] static IEnumerable<Type> hotfix { get { return (from type in Assembly.Load("Assembly-CSharp").GetTypes() select type); } } }
[Patch](补丁修改方法)标签,Inject前后DLL对比
为每个方法生成一个枚举ID
2021.6.3 更新
现在已经支持新增字段
