General

What this skill does


# Unreal C++ Skill

C++ programming for Unreal Engine development.

## Overview

This skill provides capabilities for implementing Unreal Engine gameplay and systems using C++, including the reflection system, macros, and engine integration.

## Capabilities

### UCLASS System
- Implement UCLASS macros
- Handle UPROPERTY specifiers
- Create UFUNCTION methods
- Manage USTRUCT types

### Memory Management
- Use smart pointers
- Handle garbage collection
- Manage object lifecycles
- Implement weak references

### Engine Integration
- Create Actor classes
- Implement Components
- Handle Subsystems
- Create Plugins

### Blueprint Exposure
- Expose C++ to Blueprint
- Handle BlueprintCallable
- Implement BlueprintNativeEvent
- Create Blueprint Function Libraries

## Prerequisites

- Unreal Engine 5.0+
- Visual Studio 2022 / Rider
- C++ programming knowledge

## Usage Patterns

### Actor Class

```cpp
UCLASS()
class MYGAME_API AMyCharacter : public ACharacter
{
    GENERATED_BODY()

public:
    AMyCharacter();

    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Stats")
    float Health = 100.f;

    UFUNCTION(BlueprintCallable, Category = "Combat")
    void TakeDamage(float Damage);

protected:
    virtual void BeginPlay() override;
    virtual void Tick(float DeltaTime) override;
};
```

### Component

```cpp
UCLASS(ClassGroup=(Custom), meta=(BlueprintSpawnableComponent))
class MYGAME_API UHealthComponent : public UActorComponent
{
    GENERATED_BODY()

public:
    UPROPERTY(BlueprintAssignable)
    FOnHealthChanged OnHealthChanged;

    UFUNCTION(BlueprintCallable)
    void ModifyHealth(float Delta);

private:
    UPROPERTY(EditDefaultsOnly)
    float MaxHealth = 100.f;

    float CurrentHealth;
};
```

## Best Practices

1. Use UPROPERTY for GC visibility
2. Forward declare where possible
3. Use interfaces for decoupling
4. Profile with Unreal Insights
5. Follow Unreal coding standards

Included

Access comprehensive LaTeX templates, formatting requirements, and submission guidelines for major scientific publication venues (Nature, Science, PLOS, IEEE, ACM), academic conferences (NeurIPS, ICML, CVPR, CHI), research posters, and grant proposals (NSF, NIH, DOE, DARPA). This skill should be used when preparing manuscripts for journal submission, conference papers, research posters, or grant proposals and need venue-specific formatting requirements and templates.

let-fate-decide

Included

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
