Write Unreal Engine 5 C++ gameplay code: the UCLASS/UPROPERTY/UFUNCTION reflection macros, the Gameplay Framework (GameMode, Pawn, Character, PlayerController, Actor components), and the module Build.cs. Use when writing or debugging UE C++, deriving from AActor/ACharacter/ AGameModeBase, exposing properties to the editor or Blueprints, or when the user mentions Unreal C++, UCLASS, GENERATED_BODY, GameMode, ACharacter, or .Build.cs.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Unreal C++ Gameplay

Write correct UE5 gameplay C++: the reflection macros that connect C++ to the editor and
Blueprints, the Gameplay Framework class roles, and module dependencies. Targets **UE 5.4+**.

## When to use

- Use when creating C++ gameplay classes (`AActor`, `APawn`, `ACharacter`, `AGameModeBase`,
  `UActorComponent`), exposing properties/functions with `UPROPERTY`/`UFUNCTION`, setting up a
  GameMode's default classes, or adding a module dependency in `*.Build.cs`.
- Use when the project has a `Source/` tree with `*.h`/`*.cpp` using `UCLASS`, and `*.Build.cs`.

**When *not* to use:** designer-facing visual logic → `unreal-blueprints`. Player input
binding details → `unreal-enhanced-input`. AI logic → `unreal-behavior-trees`. This skill owns
the C++ class/reflection foundation those build on.

## Core workflow

1. **Name with the right prefix.** `A` = Actor-derived, `U` = `UObject`/component-derived,
   `F` = plain struct, `E` = enum, `I` = interface. The prefix must match the base class.
2. **Declare the class with reflection macros.** `UCLASS()` above the class, `GENERATED_BODY()`

How to install

The exact contents, by fingerprint

mdr add ukanwat/overtime/unreal-cpp-gameplay@sha256:dcce71f6ac30bce9

The line at the top of this page pins the label git:20260812.5b73825, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
