Code-first 2D game engine
for .NET 10
Everything you need — scenes, ECS, audio, input, collision, particles, and UI — in one NuGet package. No editor. No visual tools. Just C#.
What's included
GPU Rendering
Hardware-accelerated via SDL3 GPU — Vulkan, Metal, and D3D12. Sprites, sprite sheets, cameras, particles, and render targets.
Hybrid ECS
Components for data, Behaviors for per-entity logic with DI, Systems for batch processing. One World per scene.
Input
Keyboard, mouse, and gamepad. Polling and event-driven. Input layers for UI-eats-input patterns.
Spatial Audio
Distance attenuation, stereo panning, configurable falloff. Audio source and listener ECS components included.
Collision
AABB and circle colliders, spatial queries, collision events. Kinematic character controller built-in.
Animation
Clip-based animation with state machines, blend trees, layers, and direct Aseprite JSON import.
Tilemaps
Native Tiled map loading and rendering. Multiple layers, tile properties, and object groups.
UI System
Buttons, sliders, text inputs, dialogs, scroll views, tooltips, and dropdowns — all integrated with ECS and DI.
Asset Pipeline
Unified loader with ref-counted caching and typed manifests for parallel preloading. Assets release when the scene unloads.
Looks like this
```csharp
var builder = GameApplication.CreateBuilder(args);
builder.Configure(options =>
{
options.Window.Title = "My Game";
options.Window.Width = 1280;
options.Window.Height = 720;
});
builder.AddScene();
await using var game = builder.Build();
await game.RunAsync();
```
```csharp
public class GameScene : Scene
{
protected override void OnRender(GameTime gameTime)
{
Renderer.DrawText("Hello, Brine2D!", 100, 100, Color.White);
}
protected override void OnUpdate(GameTime gameTime)
{
if (Input.IsKeyPressed(Key.Escape))
Game.RequestExit();
}
}
```
