Getting Started with MonoGame vs FNA

MonoGame is an excellent choice for developers looking for higher control and a broad platform support for game development using C#. Whereas, FNA, while derived from MonoGame, is targeted more towards preserving the XNA game library with a focus on open platforms and free open-source development.

Key Differences Between MonoGame and FNA

• MonoGame supports numerous platforms including iOS, Android, macOS, tvOS, Linux, PlayStation 4, PlayStation Vita, Xbox One, Nintendo Switch, while FNA primarily targets desktop platforms.
• FNA strictly utilizes Free Open Source Software, while MonoGame allows the use of both open and closed source tools.
• MonoGame had initial support for 2D development, later advancing to 3D, while FNA focuses on replicating XNA 4 libraries.
• MonoGame supports lower-level programming, providing more control over the development process compared to FNA, which primarily focuses on providing an XNA4 implementation.

What Is MonoGame and Who’s It For?

MonoGame is a free, open source, C# framework widely adopted by game developers for creating games across multiple platforms including iOS, Android, macOS, tvOS, Linux, PlayStation 4, PlayStation Vita, Xbox One, and Nintendo Switch. Initially released in September 2009 by the MonoGame Team, it’s known for reimplementing Microsoft’s XNA 4 API and being at the core of hit games such as Bastion, Celeste and Fez.

This framework is ideal for game developers who require a high level of control over the game development process. It necessitates basic knowledge of the C# programming language and is optimal for multi-platform projects, particularly 2D development.

Pros of MonoGame

• Excellent for creating games for multiple platforms
• Open source and community-maintained
• Support for both 2D and 3D games
• Possibility of extending to various platforms supported by .NET

Cons of MonoGame

• Requires understanding of C# programming language
• Not suitable for developers seeking a WYSIWYG environment
• Lack of frequent feature updates

What Is FNA and Who’s It For?

FNA is a reimplementation of the Microsoft XNA Game Studio 4.0 Refresh libraries, developed by Ethan Lee. It’s designed to preserve the XNA game library by implementing XNA features accurately. FNA targets open platforms like Windows, macOS, GNU/Linux, iOS, tvOS, Xbox, Nintendo Switch, and Google Stadia.

This technology is best for developers striving for an open-source, yet precise, reimplementation of XNA4 with the added advantage of porting to multiple platforms.

Pros of FNA

• Accurate reimplementation of XNA4 behavior
• Supports multiple open platforms
• Strict use of Free Open Source Software

Cons of FNA

• Does not support non-desktop platforms
• Non-support for closed and proprietary technologies

MonoGame vs FNA: Pricing

Both MonoGame and FNA reign as free, open-source frameworks targeted towards developers.

MonoGame

MonoGame, a powerful, open-source, C# framework, is a totally free resource. Despite its myriad capabilities and consistent updates, this platform straddles the realm of tech without charging users a single dime. From seasoned game developers to novices dipping their toes into the programming waters, MonoGame is ever-accommodating without ever demanding payment. However, the use of certain extensions of high-level programming, particularly for iOS and Android, may incur some cost.

FNA

FNA too positions itself in the same league as a free, open-source reimplementation of the XNA Game Studio 4.0. It has a devout commitment to providing software unrestricted by proprietary limitations. Boasting features that match those of its counterparts, and accommodating a cornucopia of games, this versatile platform provides invaluable tech resources without imposing a price tag.

Code Examples for MonoGame & FNA

MonoGame: Animated Sprite Character

This MonoGame example showcases how to create an animated sprite character. Make sure you properly include the MonoGame framework before proceeding. Adding the sprite sheet you intend to use is also required.

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;

class AnimatedSprite
{
    Texture2D texture;
    int rows, columns;
    int currentFrame = 0;
    int totalFrames;
    
    public AnimatedSprite(Texture2D tex, int row, int col)
    {  
        texture = tex;
        rows = row;
        columns = col;
        totalFrames = rows * columns;
    }
    public void Update()
    {  
        currentFrame++;
        if (currentFrame == totalFrames)
            currentFrame = 0;
    }

    public void Draw(SpriteBatch sb, Vector2 location)
    {  
        int width = texture.Width / columns;
        int height = texture.Height / rows;
        int row = (int)((float)currentFrame / (float)columns);
        int column = currentFrame % columns;
        
        Rectangle sourceRectangle = new Rectangle(width * column, height * row, width, height);
        Rectangle destinationRectangle = new Rectangle((int)location.X, (int)location.Y, width, height);

        sb.Draw(texture, destinationRectangle, sourceRectangle, Color.White);
    }
}

FNA: Basic 2D Transformation

In this FNA code example, you’ll see how to perform a basic 2D transformation on a sprite. Therefore, you need to load your FNA libraries and an image file of a sprite to see this code in action.

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;

public class Game1 : Game
{
    GraphicsDeviceManager graphics;
    SpriteBatch spriteBatch;
    Texture2D myTexture;
    Vector2 spritePosition = Vector2.Zero;
    Vector2 spriteOrigin;
    float spriteRotation = 0f;
    float spriteScale = 1f;

    public Game1()
    {  
        graphics = new GraphicsDeviceManager(this);
        Content.RootDirectory = "Content";
    }
    protected override void LoadContent()
    {  
        spriteBatch = new SpriteBatch(GraphicsDevice);
        myTexture = Content.Load<Texture2D>("mySprite");
        spriteOrigin = new Vector2(myTexture.Width / 2, myTexture.Height / 2);
    }

    protected override void Update(GameTime gameTime)
    {
        spriteRotation += (float)gameTime.ElapsedGameTime.TotalSeconds;
    }

    protected override void Draw(GameTime gameTime)
    {  
        GraphicsDevice.Clear(Color.CornflowerBlue);
        spriteBatch.Begin();
        spriteBatch.Draw(myTexture, spritePosition, null, Color.White, spriteRotation, spriteOrigin, spriteScale, SpriteEffects.None, 1);
        spriteBatch.End();
        base.Draw(gameTime);
    }
}

So, MonoGame or FNA: Which Is Your Code Crusader?

The outcome of MonoGame versus FNA battle is not binary, it’s pivotal. It tailors to your unique needs as a developer. Let’s dissect it.

The Platform Agnostic Game Developers

For you, MonoGame wins. Its multi-platform capabilities, from iOS, Android to gaming consoles like Nintendo Switch, proves its robustness. Its pedigree, seen in games like Bastion and Fez, testifies its power. The community support, including game schooling and tutorials, ensures you’re not alone.
