fennecs 0.5.0-beta

fennecs is a lightweight, performant, and expressive ECS library for game & simulations written in modern C#.

It's designed to be easy to use, with minimal boilerplate and no code generation or reflection required.

🚀 Quickstart

📦> dotnet add package fennecs

Here's a simple example to get you started:

// Create a world
var world = new fennecs.World();

// Spawn an entity with a Position component
var entity = world.Spawn().Add<Vector3>();

// Create a query to update positions
var query = world.Query<Vector3>().Stream();

// Run the query
stream.For(
    uniform: Time.deltaTime,
    action: static (float dt, ref Vector3 position) => 
    {
        pos.Y -= 9.81f * dt;
    }
);
