Godot C# Skill

C# programming for Godot Engine development.

Overview

This skill provides capabilities for implementing game logic using C# in Godot, leveraging .NET integration.

Capabilities

C# Integration

• Node class inheritance
• Attribute-based exports
• Signal definitions
• Callable system

.NET Features

• NuGet packages
• Async/await patterns
• LINQ queries
• .NET libraries

Interoperability

• Call GDScript from C#
• Expose to GDScript
• Handle Variant types
• Manage signals

Performance

• Struct usage
• Memory management
• Object pooling
• Span usage

Prerequisites

• Godot 4.0+ with .NET support
• .NET SDK installed
• C# IDE (VS Code, Rider)

Usage Patterns

Node Script

using Godot;

public partial class Player : CharacterBody2D
{
    [Export]
    public float Speed { get; set; } = 200f;

    [Signal]
    public delegate void HealthChangedEventHandler(int newHealth);

    private int _health = 100;

    public override void _Ready()
    {
        // Initialize
    }

    public override void _PhysicsProcess(double delta)
    {
        var velocity = Vector2.Zero;
        velocity.X = Input.GetAxis("move_left", "move_right");
        velocity.Y = Input.GetAxis("move_up", "move_down");
        Velocity = velocity.Normalized() * Speed;
        MoveAndSlide();
    }
}

Signal Connection

button.Pressed += OnButtonPressed;
// or
button.Connect("pressed", Callable.From(OnButtonPressed));

Best Practices

1. Use partial classes
2. Leverage NuGet packages
3. Handle node lifecycle
4. Profile memory usage
5. Use source generators
