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
