# Introduction

**pecs** is a library for integrating Entity Component System (ECS) with game

development. It is inspired by [**entt**](https://github.com/skypjack/entt),

another ECS library but for C++.

From [Wikipedia](https://en.wikipedia.org/wiki/Entity_component_system):

> **Entity component system (ECS)** is a software architectural pattern mostly

> used in video game development for the representation of game world objects.

> An ECS comprises _entities_ composed of _components_ of data, with _systems_

> which operate on entities' components.

## Code Example

```python

import pecs

from dataclasses import dataclass

@dataclass

class Position:

    x: float

    y: float

def update(registry: pecs.Registry):

    view: list = registry.view(Position)

    for entity in view:

        pos = registry.get(entity, Position)

        ...

def main():

    registry = pecs.Registry()

    for i in range(10):

        entity = registry.create()

        registry.emplace(entity, Position(i * 2, i))

    update(registry)

if __name__ == "__main__":

    main()

```
