Overview

Use HarmonyLib effectively by following best practices for the library.

This skill has two parts:

1. KSA Modding Patterns — how Harmony is actually wielded in THIS repository's KSA game mods. Read this first; it reflects the conventions every mod here follows and the real game types/methods that get patched.
2. Harmony Library Reference — a general AI-optimized reference for the library's full feature set.

---

KSA Modding Patterns (this repo)

These are the conventions used across ~40 patch files in this project. Follow them when creating or modifying a KSA mod. The verbatim code below is quoted from real mods.

Mod lifecycle: the Patcher.cs contract

Every top-level mod has a Patcher.cs with a static Patcher class exposing exactly two methods that the StarMap mod loader calls by name (not by attribute or interface):

public static void Patch()    // called on mod load — apply all patches here
public static void Unload()   // called on mod unload — remove all patches here

There is no [Patch]/[Unpatch]/ModInfo attribute on these methods. The loader invokes Patch() and Unload() by convention.

The Harmony instance

• Stored as a single nullable static field: private static Harmony? _harmony;
• The ID is a string literal, either the mod folder name ("zippo", "flexo", "thug-life") or a fully-qualified namespace ("MeowSci.Blinky", "MeowSci.Unscience"). Pick one and reuse the exact same string for UnpatchAll.
• Created either inline (= new Harmony("zippo")) or lazily in Patch() (_harmony = new Harmony("MeowSci.Blinky")). Lazy creation pairs naturally with _harmony = null in Unload().

HotkeyGuard is mandatory (see AGENTS.md)

Every top-level mod MUST apply HotkeyGuard from MeowSci.KsaAbstractions. Patch it in Patch(), unpatch it first in Unload():

HotkeyGuard.Patch(_harmony);    // in Patch()
HotkeyGuard.Unpatch(_harmony);  // in Unload(), before other unpatches

Two patching styles

Style A — attribute discovery via PatchAll (use when patches are declared with [HarmonyPatch] attributes on classes/methods in the assembly). Put [HarmonyPatch] on the Patcher class to make its own annotated methods discoverable:

[HarmonyPatch]
internal static class Patcher
{
    private static Harmony? _harmony = new Harmony("zippo");

    public static void Patch()
    {
        try
        {
            _harmony?.PatchAll(typeof(Patcher).Assembly);
            if (_harmony != null) HotkeyGuard.Patch(_harmony);
        }
        catch (Exception ex)
        {
            Console.WriteLine($"zippo: Error applying patches: {ex.Message}");
        }
    }

    public static void Unload()
    {
        try
        {
            if (_harmony != null) HotkeyGuard.Unpatch(_harmony);
            _harmony?.UnpatchAll("zippo");   // same literal as the Harmony id
            _harmony = null;
        }
        catch (Exception ex)
        {
            Console.WriteLine($"zippo: Error removing patches: {ex.Message}");
        }
    }
}

Style B — manual Apply(harmony) / Remove(harmony) helpers (the dominant style for .lib projects; gives precise control and clean unpatching). Each feature lives in a *Patches.cs static class with paired Apply/Remove:

internal static class Patcher
{
    private static Harmony? _harmony;

    public static void Patch()
    {
        _harmony = new Harmony("MeowSci.Blinky");
        BlinkyPatches.Apply(_harmony);
        HotkeyGuard.Patch(_harmony);
    }

    public static void Unload()
    {
        if (_harmony != null)
        {
            BlinkyPatches.Remove(_harmony);
            HotkeyGuard.Unpatch(_harmony);
        }
        _harmony = null;
    }
}

The two styles compose: flexo calls PatchAll(...) AND FlexoPatches.Apply(...) (the latter needed because one patch requires a custom priority that attributes don't set here). The unscience supermod consolidates many .lib patch sets under one Harmony instance by calling each lib's Apply/Remove in turn.

The *Patches.cs manual-patch helper (Style B canonical form)

This is the most important pattern in the repo. A static helper resolves the target MethodInfos, stores them (plus the prefix/postfix MethodInfos) in static fields, patches them, and unpatches by the same stored references:

public static class IFeelSeenPatches
{
    private static VehicleTracker? _tracker;
    private static MethodInfo? _vehicleGetWorldMatrix;
    private static MethodInfo? _getWorldMatrixPrefix;

    public static void Apply(Harmony harmony, VehicleTracker tracker)
    {
        _tracker = tracker;
        // resolve our own private patch method by name
        _getWorldMatrixPrefix = typeof(IFeelSeenPatches)
            .GetMethod(nameof(GetWorldMatrixPrefix), BindingFlags.NonPublic | BindingFlags.Static)!;
        // resolve the private game method by string name (AccessTools ignores visibility)
        _vehicleGetWorldMatrix = AccessTools.Method(typeof(Vehicle), "GetWorldMatrix");
        harmony.Patch(_vehicleGetWorldMatrix, prefix: new HarmonyMethod(_getWorldMatrixPrefix));
        Console.WriteLine("i-feel-seen.lib: patches applied");
    }

    public static void Remove(Harmony harmony)
    {
        if (_vehicleGetWorldMatrix != null && _getWorldMatrixPrefix != null)
            harmony.Unpatch(_vehicleGetWorldMatrix, _getWorldMatrixPrefix);  // targeted unpatch
        _tracker = null;
        _vehicleGetWorldMatrix = null;
        _getWorldMatrixPrefix = null;
        Console.WriteLine("i-feel-seen.lib: patches removed");
    }

    private static bool GetWorldMatrixPrefix(Vehicle __instance, Camera camera, ref float4x4? __result)
    {
        if (_tracker == null || !_tracker.IsTracked(__instance))
            return true;                 // not ours — run the original
        // ... compute custom matrix ...
        __result = /* ... */;
        return false;                    // skip original, our __result is returned
    }
}

Key points:

• harmony.Patch(original, prefix: new HarmonyMethod(methodInfo)) is the manual patch call. Use the prefix: or postfix: named arg.
• Remove uses harmony.Unpatch(original, prefixMethodInfo) for a targeted unpatch (preferred in .lib helpers so it never touches another lib's patches). Top-level Patcher.cs files instead use harmony.UnpatchAll("<id>").
• Apply can take extra context args (e.g. a VehicleTracker) which the prefix reads from a static field.

HotkeyGuard — the canonical shared prefix (study this)

ksa-abstractions.lib/HotkeyGuard.cs is the reference implementation of a clean, reusable, target-a-game-method patch. It blocks game hotkeys while ImGui has text focus by patching GameSettings.OnKeyAll and forcing its bool return value:

public static void Patch(Harmony harmony)
{
    _original = AccessTools.Method(typeof(GameSettings), nameof(GameSettings.OnKeyAll));
    _prefix = typeof(HotkeyGuard).GetMethod(nameof(Prefix), BindingFlags.NonPublic | BindingFlags.Static)!;
    harmony.Patch(_original, prefix: new HarmonyMethod(_prefix));
    Console.WriteLine("ksa-abstractions: HotkeyGuard patch applied");
}

private static bool Prefix(ref bool __result)
{
    if (!Program.ConsoleWindow.IsOpen && ImGui.GetIO().WantTextInput)
    {
        __result = true;   // tell the game "the key was handled"
        return false;      // skip the real OnKeyAll → hotkeys don't fire
    }
    return true;           // otherwise let hotkeys work normally
}

This is the textbook "conditionally skip original and substitute the return value" prefix: ref bool __result + return false.

Injected arguments seen in this repo

Injected	Real usage here
__instance	Vehicle __instance, PartModel __instance, Camera __instance, PartModelModule __instance, Controller __instance — the game object being patched
ref __result	ref bool __result (HotkeyGuard), ref float4x4? __result (i-feel-seen) — write it then return false to override
named original args	Camera camera, IViewport viewport (Viewport before KSA 2026.9.7.5402), int inFrameIndex, CommandBuffer commandBuffer — match the game method's real parameter names
ref <param>	ref PartModel.PerInstanceData instanceData — mutate a struct argument in place (paint, deform, emissive)
___PrivateField	triple-underscore reads a private game field directly into the patch. No gatOS or unscience patch currently uses it — every field these patches need is public (e.g. the camera transform is the public Controller.Camera). Harmony validates the name at patch time, so a misspelled or non-existent field throws from Patch() and, in a shared-Harmony host, aborts the rest of the chain — cite a real field or don't reach for this
positional	PartModel.PerInstanceData __0, IViewport __1 (IvaForceRender) — by-index when you don't want to name them

Holding patch state: static *PatchState / manager singletons

Patch methods are static, so mutable config lives in a dedicated static class the prefix checks at runtime:

// prefix gates rendering on a static flag toggled by the mod's UI
private static bool PartModelModulePrefix(PartModelModule __instance)
{
    if (BlinkyPatchState.RenderPixelParts) return true;
    return !__instance.Parent.FullPart.Id.StartsWith("pixel_");
}

BlinkyPatchState / ShinyPatchState are plain static classes holding bool toggles. For render hooks that need GPU resources, the pattern is a manager singleton with static Active/Instance that the postfix dispatches into, e.g. ThugLifeRenderManager:

private static void RenderMainPassPostfix(CommandBuffer commandBuffer)
{
    if (!ThugLifeRenderManager.Active) return;          // cheap guard first
    try { ThugLifeRenderManager.Instance?.RecordDraws(commandBuffer); }
    catch (Exception ex) { Console.WriteLine($"thug-life: render postfix error: {ex.Message}"); }
}

Note: Dispose() on the manager sets Active = false before freeing GPU resources, so an in-flight render frame can't use-after-free.

KSA-specific techniques worth knowing

Render-data injection via Unsafe.As struct reinterpretation. Several mods (humble-arteest paint & emissive, mesh-deform) write into the unused padding bytes of the game's per-instance GPU struct. Define an overlay struct with [StructLayout(LayoutKind.Sequential)] matching the real layout, reinterpret the ref param, and assign the named fields:

private static void AddInstancePrefix(PartModel __instance, ref PartModel.PerInstanceData instanceData)
{
    if (!VehiclePaint.TryGetEffectiveColor(__instance, out var color)) return;
    ref var paintable = ref Unsafe.As<PartModel.PerInstanceData, PaintablePerInstanceData>(ref instanceData);
    paintable.PaintR = color.X;   // PaintR/G/B overlay the struct's packing1/2/3 bytes
    paintable.PaintG = color.Y;
    paintable.PaintB = color.Z;
}

Two-patch coordination via ThreadLocal<T>. When the data you need to inject (in a deep patch) isn't available in that method's args, capture it in an earlier patch and stash it thread-locally. mesh-deform captures the current Part in a prefix on PartModelModule.UpdateRenderData, then reads it in a prefix on PartModel.AddInstance. Safe because KSA renders single-threaded:

public static readonly ThreadLocal<Part?> CurrentPart = new();
// patch 1: CurrentPart.Value = __instance.Parent;
// patch 2: var part = CapturePartPatch.CurrentPart.Value;  // who is being rendered right now

Writing a private game field via AccessTools.Field + SetValue. glass overrides the camera FOV by resolving Camera._fovRadians once in Apply and writing it in a prefix on UpdateProjection:

_fovRadiansField = AccessTools.Field(typeof(Camera), "_fovRadians");   // once, in Apply
// in prefix:
_fovRadiansField.SetValue(__instance, targetRadians);

Patching a constructor. IvaForceRender patches PartModel's constructor to mutate newly-created part templates:

_ctorOriginal = AccessTools.Constructor(typeof(PartModel), new[] { typeof(PartModelModule.Template) });
harmony.Patch(_ctorOriginal, postfix: new HarmonyMethod(_ctorPostfix));

Setting patch priority for ordering. When your prefix must run before everything else on a hot game method (flexo's solver on Universe.ExecuteNextVehicleSolvers), set priority on the HarmonyMethod:

var prefix = new HarmonyMethod(typeof(FlexoSolverPatch), nameof(BeforeVehicleSolvers))
{
    priority = Priority.First
};
harmony.Patch(original, prefix: prefix);

Calling a private game method via Traverse. flexo invokes a private recompute after editing parts:

Traverse.Create(vehicle.Parts).Method("RecomputeStaticMass").GetValue();

Transpiler (rare — only jplrepo uses one). Injects a call before a specific ImGui call inside a game method, with a fallback warning if the IL target isn't found:

foreach (var instr in instructions)
{
    if (!injected && instr.Calls(setCursorPosY))
    {
        yield return new CodeInstruction(OpCodes.Call,
            AccessTools.Method(typeof(Patcher), nameof(SaveMenuCursorPos)));
        injected = true;
    }
    yield return instr;
}

Attribute-based menu-bar postfix. UI mods append to the game menu by postfixing Program.DrawProgramMenusHook (or GaugeCanvas.OnDrawMenuBar), often applied with harmony.CreateClassProcessor(typeof(MyMenuPatch)).Patch():

[HarmonyPatch(typeof(Program), nameof(Program.DrawProgramMenusHook))]
[HarmonyPostfix]
private static void Postfix() { /* ImGui.BeginMenu(...) ... */ }

Logging & error-handling conventions

• Log with Console.WriteLine (per AGENTS.md). Standard messages: "<mod>: Harmony patches applied" / "<mod>: patches removed", and on failure "<mod>: Error applying patches: {ex.Message}".
• Wrap Patch()/Unload() bodies in try/catch so a failed patch can't take down mod loading.
• Wrap the body of render/hot-path prefixes & postfixes in try/catch too — an exception thrown from inside a patch on a per-frame game method would otherwise spam or destabilize the game loop.

Real game types & methods patched in this repo (targeting reference)

Game type.method	Patch	What the mod does
GameSettings.OnKeyAll	prefix (skip)	HotkeyGuard — block hotkeys during ImGui text input
Vehicle.GetWorldMatrix / Vehicle.UpdateRenderData	prefix (skip)	i-feel-seen — override render transform/distance for tracked vehicles
Camera.ChangeFieldOfView	prefix (skip)	glass — block stock FOV input when override active
Camera.UpdateProjection	prefix + field write	glass — inject custom FOV via Camera._fovRadians
PartModel.AddInstance	prefix (ref PerInstanceData)	humble-arteest paint, mesh-deform — inject GPU per-instance data
PartModelDynamic.AddInstance	prefix (ref PerInstanceData)	humble-arteest engine emissive temperature/TFI
PartModel ctor / PartModel.AddInstance	postfix	IvaForceRender — force interior meshes visible
PartModelModule.UpdateRenderData (+ Dynamic/Glass variants)	prefix (skip)	blinky/shiny — conditionally skip rendering pixel_/shiny_ parts; mesh-deform Part capture
PartModelRenderer.UpdateRenderData(IViewport, int) (Viewport before 5402)	prefix	flexo — render editor parts in main pass (note arg-type overload match)
Universe.ExecuteNextVehicleSolvers	prefix (Priority.First)	flexo — run hinge solver before vehicle solvers
SuperMeshRenderSystem.RenderMainPass	postfix	thug-life — record extra quad draws into the command buffer
Controller.OnFrame (Orbit/Fly)	prefix (___Transform)	camera-controller-override — keyframe camera playback
Program.DrawProgramMenusHook / GaugeCanvas.OnDrawMenuBar	postfix	menu-bar UI injection

To find the real signatures of any of these, look in decomp/ksa (read strategically — those files are large).

Harmony Library Reference (AI-Optimized)

HarmonyLib runtime patching library for .NET/Mono. Patches methods without modifying DLLs on disk.

Core Concepts

• Patches coexist: Multiple Harmony patches on the same method do not conflict
• Patch methods MUST be static: Instance state stored in static variables
• Unique ID required: Use reverse domain notation (e.g., com.example.mymod)

Setup

using HarmonyLib;

// Create instance
var harmony = new Harmony("com.example.mymod");

// Apply all annotated patches in assembly
harmony.PatchAll();

// Or manual patching
harmony.Patch(originalMethod, 
    prefix: new HarmonyMethod(typeof(MyPatch).GetMethod("Prefix")),
    postfix: new HarmonyMethod(typeof(MyPatch).GetMethod("Postfix")));

Patch Types

1. Prefix

Runs before original. Can skip original and modify arguments.

[HarmonyPatch(typeof(TargetClass), "TargetMethod")]
class MyPatch
{
    // Return false to skip original (and subsequent prefixes with side effects)
    // Return true or void to continue
    static bool Prefix(ref int someArg, ref int __result)
    {
        someArg = 10;        // Modify argument (needs ref)
        __result = 42;       // Set return value (needs ref)
        return false;        // Skip original
    }
}

2. Postfix

Runs after original. Always runs (unless exception thrown). Preferred for compatibility.

static void Postfix(ref int __result, int someArg)
{
    __result *= 2;  // Modify return value (needs ref)
}

// Pass-through postfix (for IEnumerable or special cases)
static IEnumerable<T> Postfix(IEnumerable<T> __result)
{
    foreach (var item in __result)
        yield return ModifyItem(item);
}

3. Finalizer

Wraps original + all patches in try/catch. Handles/suppresses exceptions.

// Suppress all exceptions
static Exception Finalizer() => null;

// Observe exception
static void Finalizer(Exception __exception)
{
    if (__exception != null) Log(__exception);
}

// Replace exception
static Exception Finalizer(Exception __exception)
{
    return __exception != null ? new CustomException(__exception) : null;
}

4. Transpiler

Modifies IL instructions at patch time (not runtime). Advanced use only.

static IEnumerable<CodeInstruction> Transpiler(
    IEnumerable<CodeInstruction> instructions,
    ILGenerator generator,      // Optional: for labels/locals
    MethodBase original)        // Optional: original method info
{
    var codes = new List<CodeInstruction>(instructions);
    // Modify codes list
    return codes;
}

CodeMatcher utility for transpilers:

static IEnumerable<CodeInstruction> Transpiler(IEnumerable<CodeInstruction> instructions)
{
    return new CodeMatcher(instructions)
        .MatchStartForward(new CodeMatch(OpCodes.Call, AccessTools.Method(typeof(Foo), "Bar")))
        .SetOperandAndAdvance(AccessTools.Method(typeof(MyClass), "MyReplacement"))
        .InstructionEnumeration();
}

5. Reverse Patch

Copies original method into your stub. Call private/protected methods directly.

[HarmonyPatch(typeof(TargetClass), "PrivateMethod")]
class MyPatch
{
    // Stub signature must match original (instance methods need instance as first param)
    [HarmonyReversePatch]
    static int CallPrivateMethod(TargetClass instance, int arg)
    {
        // Stub body replaced by original's IL
        throw new NotImplementedException("Stub");
    }
}
// Usage: int result = MyPatch.CallPrivateMethod(targetInstance, 5);

Types: HarmonyReversePatchType.Original (default, unpatched) or Snapshot (with existing transpilers)

Injected Arguments

Name	Type	Description
__instance	class type	this for instance methods
__result	return type	Return value (use ref to modify)
__state	any	Share state between Prefix/Postfix (same class only)

[HarmonyBefore("other.mod.id")]      // Run before specific mod
[HarmonyAfter("other.mod.id")]       // Run after specific mod

Priority values: First=0, VeryHigh=100, High=200, Higher=300, Normal=400, Lower=500, Low=600, VeryLow=700, Last=800

Auxiliary Methods

[HarmonyPatch(typeof(MyClass), "MyMethod")]
class MyPatch
{
    // Called before patching; return false to skip this patch class
    static bool Prepare(MethodBase original, Harmony harmony)
    {
        return original != null; // Example: only patch if method exists
    }
    
    // Dynamic target selection (replaces [HarmonyPatch] target)
    static MethodBase TargetMethod()
    {
        return AccessTools.Method(typeof(SomeClass), "SomeMethod");
    }
    
    // Multiple targets
    static IEnumerable<MethodBase> TargetMethods()
    {
        yield return AccessTools.Method(typeof(A), "Method");
        yield return AccessTools.Method(typeof(B), "Method");
    }
    
    // Called after patching; can handle/suppress exceptions
    static Exception Cleanup(MethodBase original, Exception ex)
    {
        return null; // Suppress exception
    }
}

Utilities

AccessTools

Reflection helper. All methods ignore visibility (public/private/etc).

AccessTools.Method(typeof(MyClass), "MethodName")
AccessTools.Method(typeof(MyClass), "MethodName", new[] { typeof(int) })
AccessTools.Field(typeof(MyClass), "fieldName")
AccessTools.Property(typeof(MyClass), "PropertyName")
AccessTools.Constructor(typeof(MyClass), new[] { typeof(int) })
AccessTools.Inner(typeof(MyClass), "NestedClassName")
AccessTools.TypeByName("Namespace.ClassName")

Traverse

Fluent reflection with null-safety.

// Read private field
var value = Traverse.Create(instance).Field("_privateField").GetValue<int>();

// Set private field
Traverse.Create(instance).Field("_privateField").SetValue(42);

// Call private method
Traverse.Create(instance).Method("PrivateMethod", arg1, arg2).GetValue();

// Chain access
var deep = Traverse.Create(obj).Field("a").Property("B").Field("c").GetValue();

Execution Order

1. Prefixes (highest priority first)
   • Void/no-ref prefixes always run (side-effect free)
   • First return false skips remaining prefixes with side effects AND original
2. Original (possibly transpiled)
3. Postfixes (lowest priority first) - always run unless exception
4. Finalizers (lowest priority first) - always run, handle exceptions

Edge Cases & Limitations

Issue	Cause	Workaround
Patch not called	Method inlined by JIT	Patch caller instead, or use [MethodImpl(MethodImplOptions.NoInlining)] if you control the code
Generics shared	Reference types share implementation	Check __instance.GetType() in patch; value types usually not shared
Can't patch static constructor	Runs before patching	Time patching carefully, or accept it runs at wrong time
Can't patch native/extern	No IL to modify	Transpiler-only patch returning new implementation (loses ability to call original)
MissingMethodException (Unity)	Patching before Unity initialization	Delay patching until after scene load
base.Method() not working	Resolved at compile time	Use Reverse Patch
InvalidProgramException	Method has no RET instruction	Use Transpiler to fix IL

Debugging

// Enable debug logging (writes to Desktop/harmony.log.txt)
Harmony.DEBUG = true;

// Or per-patch
[HarmonyDebug]
[HarmonyPatch(...)]
class MyPatch { }

// Environment variables
// HARMONY_NO_LOG=1        - Disable logging
// HARMONY_LOG_FILE=path   - Custom log path

Common Patterns

Skip Original Conditionally

static bool Prefix(SomeType __instance)
{
    if (__instance.ShouldSkip)
    {
        return false; // Skip original
    }
    return true; // Run original
}

Wrap Original in Try/Catch

static Exception Finalizer(Exception __exception)
{
    if (__exception != null)
        Logger.Error($"Caught: {__exception}");
    return null; // Suppress
}

Replace Method Call in Original

static IEnumerable<CodeInstruction> Transpiler(IEnumerable<CodeInstruction> instructions)
{
    return new CodeMatcher(instructions)
        .MatchStartForward(new CodeMatch(OpCodes.Call, AccessTools.Method(typeof(Original), "OldMethod")))
        .SetOperandAndAdvance(AccessTools.Method(typeof(MyClass), "NewMethod"))
        .InstructionEnumeration();
}

Access Private Nested Type

static MethodBase TargetMethod()
{
    var nestedType = AccessTools.Inner(typeof(OuterClass), "PrivateNestedClass");
    return AccessTools.Method(nestedType, "TargetMethod");
}

Patch All Overloads

static IEnumerable<MethodBase> TargetMethods()
{
    return typeof(MyClass)
        .GetMethods(AccessTools.all)
        .Where(m => m.Name == "OverloadedMethod");
}
