High-performance C# ECS
A transparent discovery signal based on current public GitHub metadata.

Friflo ECS is a high performance C# ECS with focus on simplicity and reliability.
The library is designed for easy integration and a smooth developer experience.
Among various C# ECS projects, it is currently the only one fully implemented in Managed C#.
By this no use of unsafe code preventing crashes due to memory corruption.
It enables writing highly decoupled code. Data is stored in Components which are assigned to objects - aka Entities - at runtime.
Code decoupling is accomplished by dividing implementation in pure data structures (Component types) - and code (Systems) to process them.
It enables high performant system execution by storing components in continuous memory to leverage CPU caches L1, L2 & L3.
It improves CPU branch prediction by minimizing conditional branches when processing components in tight loops.
🚀 New in v3.5.0
Map components to enums
and Map tags to enums.
Introduced new pattern to process events on adding/removing components or tags more performant and concise.
🚀 New in v3.6.0
New feature: Query Generator
Generates high-performance query code and reduces boilerplate code to a minimum.
Get package on nuget or use the dotnet CLI.
dotnet add package Friflo.Engine.ECS
A survivors-like game exploiting the strength of ECS controlling a very high amount of AI units.
A Godot MultiMesh is used to enable reliable 2000 FPS.
It uses a single MultiMeshInstance2D node with a single material and shader.
Tech Demo of a 2D platformer with focus on movement mechanics.
ECS is used for core game logic, component-base abilities, physics / collisions & triggers,
state machines / behavior logic, gameplay events and UI integration. more ...
Project is hosted on GitHub and supports Desktop and WASM.
Rendering of 3D environment and 2D sprites is implemented with Raylib.
Interesting note: It combines behavior trees with ECS. more ...
Quote from developer: "Just wanted to let you know that Friflo ECS 2.0.0 works like a charm in my little game.
I use it for basically everything (landscape segments, vegetation, players, animations, collisions and even the floating dust particles are entities).
After some optimization there is no object allocation during gameplay - the allocation graph just stays flat - no garbage collection."
