Description:
pyecs 0.19
pyecs
A simple implementation of the Entity-Component pattern.
Install
This project is available on PyPI so you can simply install it via
pip install pyecs
Example
from dataclasses import dataclass
from typing import Tuple
from pyecs import Store
# 1. build your components
@dataclass
class Transform:
position: Tuple[float, float] = (0.0, 0.0)
@dataclass
class Rigidbody:
velocity: Tuple[float, float] = (0.0, 0.0)
acceleration: Tuple[float, float] = (0.0, 0.0)
if __name__ == "__main__":
# 2. intialize entity-component store
store = Store()
# 3. add some entities
scene = store.add_entity()
scene.add_child(Transform(), Rigidbody(acceleration=(1.0, 0.0)))
scene.add_child(Transform(), Rigidbody(acceleration=(0.0, 1.0)))
scene.add_child(Transform(), Rigidbody(acceleration=(1.0, 1.0)))
# 4. run everything
while True:
for entity in store.get_entities_with(Transform, Rigidbody):
transform, rigidbody = entity.get_components(Transform, Rigidbody)
rigidbody.velocity = (
rigidbody.velocity[0] + rigidbody.acceleration[0],
rigidbody.velocity[1] + rigidbody.acceleration[1],
)
transform.position = (
transform.position[0] + rigidbody.velocity[0],
transform.position[1] + rigidbody.velocity[1],
)
print(f"{transform=}\t{rigidbody=}")
Dev Setup
