It: - -- Injects itself into the game when it launches -- Loads your plugin DLLs automatically from `BepInEx/plugins/` -- Provides logging, configuration, and modding APIs -- Handles IL2CPP games (compiled to native C++ code, harder to mod than Mono) - -#### What is Harmony? - -**Harmony** is a runtime patching library that lets you modify game methods without changing the original game files: - -- **Prefix**: Run your code BEFORE the original method (can block the original) -- **Postfix**: Run your code AFTER the original method -- **Transpiler**: Modify the method's IL code directly (advanced) - -You patch methods by their type and method name - no compile-time references needed! - ---- - -## 📋 Common Patterns - -### Pattern: Periodic Timer - -```csharp -private static float _timer; -private const float INTERVAL = 10f; - -private static void UpdatePostfix() -{ - _timer += UnityEngine.Time.deltaTime; - if (_timer < INTERVAL) return; - _timer = 0f; - - // Do something every 10 seconds -} -``` - -### Pattern: Singleton Access - -```csharp -// Most game managers use the Singleton pattern -var instance = ManagerType.GetProperty("Instance").GetValue(null); -``` - -### Pattern: Safe Reflection - -```csharp -try -{ - var method = type.GetMethod("MethodName"); - if (method == null) - { - Log.LogWarning("Method not found!"); - return; - } - method.Invoke(instance, args); -} -catch (Exception ex) -{ - Log.LogError($"Reflection error: {ex.Message}"); -} -``` - -### Pattern: Patch All Overloads - -```csharp -var methods = targetType.GetMethods(BindingFlags.Public | BindingFlags.Instance); -foreach (var method in methods) -{ - if (method.Name == "TargetMethod") - { - _harmony.Patch(method, prefix: myPrefix); - } -} -``` - ---- - -## ⚠️ Common Pitfalls - -### 1. **IL2CPP Array Indexing** - -IL2CPP arrays need special handling: - -```csharp -// DON'T: arr[0] -// DO: -var getMethod = array.GetType().GetMethod("get_Item"); -var value = getMethod.Invoke(array, new object[] { 0 }); -``` - -### 2. **Timing Issues** - -Game managers may not be loaded immediately: - -```csharp -// Wait before trying to access managers -if (!_initialDelayDone) -{ - _elapsed += deltaTime; - if (_elapsed < 30f) return; // wait 30 seconds - _initialDelayDone = true; -} -``` - -### 3. **Type Name Collisions** - -Multiple assemblies may have classes with the same name: - -```csharp -// Use full namespace -FindType("YoudaGames.MonopolyPoker.Popups.RollingOffersPopup"); -``` - -### 4. **Harmony Patch Failures** - -Methods might not exist or load later: - -```csharp -try -{ - _harmony.Patch(method, prefix); -} -catch (Exception ex) -{ - Log.LogWarning($"Patch failed: {ex.Message}"); - // Method may load later - try again or check name -} -``` - ---- - -## 🎉 Example Mod Ideas - -Now that you understand the basics, try creating: - -1. **Auto Claimer** - Automatically collect daily rewards (you have this!) -2. **Speed Hack** - Patch animation methods to speed up gameplay -3. **UI Remover** - Block annoying popups (you have this!) -4. **Unlimited Resources** - Modify currency values via reflection -5. **Auto Player** - Hook game actions and make decisions automatically -6. **Visual Tweaks** - Modify Unity UI elements at runtime - ---- - -## 🐛 Debugging Tips - -### View Logs - -``` -/BepInEx/LogOutput.log -``` - -### Enable Debug Logging - -In your plugin: - -```csharp -Log.LogDebug("Debug message"); // Will show if debug level enabled -``` - -In `BepInEx/config/BepInEx.cfg`: - -```ini -[Logging.Console] -LogLevels = Fatal, Error, Warning, Message, Info, Debug -``` - - -## UnityExplorer Console Snippets - -### Dumping GameObject Information - -Replace the type with the one you need, e.g., `YoudaGames.MonopolyPoker.Popups.BoardwalkJackpotRollPopup`. - -``` -var instances = UnityEngine.Object.FindObjectsOfType(); - -foreach (var popup in instances) -{ - Console.WriteLine($"--- Begin for instance {popup} ---"); - var type = popup.GetType(); - foreach (var prop in type.GetProperties(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance)) - { - Console.WriteLine($"{prop.Name}: {prop.GetValue(popup)}"); - } - Console.WriteLine("--- End ---"); -} -``` - - -TODO: Perhaps seperate this README into a docs folder and link to it from the main README, to keep the main README concise and focused on project overview and setup. \ No newline at end of file +Note UnityExplorer is archived, need to use a fork. \ No newline at end of file diff --git a/docs/common_issues.md b/docs/common_issues.md new file mode 100644 index 0000000..206badf --- /dev/null +++ b/docs/common_issues.md @@ -0,0 +1,35 @@ + +# Common Issues + +## dnSpy Import Project + +When trying to load a disassembled project that was then reassembled with dnSpy into Visual Studio you'll encounter the error: + +`A numeric comparison was attempted on "$(_TargetFrameworkVersionWithoutV)" that evaluates to "" instead of a number, in condition "('$(TargetFrameworkIdentifier)' != '.NETCoreApp'` + +This is because the project file generated by dnSpy is adding a v to and as well as not including _TargetFrameworkVersionWithoutV.
