FNAEngine

The goal of this project is to make it easier to create new games with FNA-XNA. The FNA framework is really easy to use but with each new games or test projects, i needed to recreate a little framework.

I'm a programmer for over 25 years, i did a little of Unity and i fell in love with FNA-XNA. It's user easy to use, to customize and super quick to develop and try new things.

I used .Net 4.8 because i still have issues with .Net 6.0/7.0. It's the framework that i'm the most confortable with.

WARNING: This project is meant to learn XNA and create little games for yourself.

Working features

Some nice features are already working:

• GameHost / GameObject structure
• TextureRender: GameObject to draw texture on screen
• TextRenderer: GameObject to draw text on screen with different alignments
• SpriteRender: GameObject to draw sprite on screen
• SpriteAnimationRender: GameObject to animate sprites from png/json or from aseprite files
• SpriteAnimator: GameObject that encapsulate SpriteAnimationRender from enums
• Collider: Basic rectangle collision detection system
• RigidBody: Basic rigifbody to simulate physics in 2D (platform/side scrolling)
• TileSet: Full support to TileSet with an editor (Windows)
• Edit Mode: Edit/Save the content of your scene directly in game (F12)
• ContentManager: Custom ContentManager that hot reloads the modified texture at runtime
• IMouseEventHandler: Implement Mouse Down, Up and Click on GameObject
• Aseprite format integration for textures and sprite animations. (checkout Asperite, it's very nice for sprites and Pixel Arts: https://github.com/aseprite/aseprite (it's free if you build it yourself).
• Input: Basic input system (that i took from Michael Hicks: https://www.youtube.com/playlist?list=PL3wErD7ZIp_DtsTKoouVCxu81UQkI9VZL)
• A lot of addons to Vector2, Rectangle and GameMath.

Exemple

Check my test games that i created with this engine:

• Pong: https://github.com/Hilderin/Pong
• Platformer: https://github.com/Hilderin/Platformer

Dependencies

This projet uses:

• FNA-XNA-Wrapper (a nuget that i created to bundle FNA in a nuget package. Weirdly, nobody seems to use created one for that easy to use before or i just did not find it?!?)
• Velentr.Font.FNA: For drawing text

Work in progress

I just begun working with FNA-XNA, there's so must that can be added and upgraded.

My plan is to upgrade my Pong and Platformer games with different goodies and upgrade the engine at the same time.
