Welcome to xecs!#
GitHub: https://github.com/lukasturcani/xecs
xecs is a Python library (written in Rust!) for a performant
entity component system (ECS). You can use it to write simulations, games
or any other high-performance piece of software.
If you are familiar with Bevy and
NumPy – the API of xecs should be
familiar to you. Here is a little taste:
import xecs as xx
class Velocity(xx.Component):
value: xx.Vec2
def update_positions(
query: xx.Query[tuple[xx.Transform2, Velocity]],
) -> None:
(transform, velocity) = query.result()
transform.translation += velocity.value
The goals of xecs are as follows:
Fast: Operations are executed in parallel as much as possible and the library is written in Rust to be cache friendly and performant.
Simple: Data is defined with a dataclass-like syntax and systems are regular Python functions.
Typed: Types form an integral part of the API, making code clean but also easily verified with type checkers.
NumPy-friendly: Our data types can be used seamlessly with NumPy.
Python-friendly: User code is regular Python code, allowing full integration with the Python ecosystem. We avoid things like Numba which cause pain during debugging and limit use of pure Python libraries.
