The teeniest, tiniest ECS system

tinyecs - The teeniesst, tiniest ESC system

After reading part 2 and 3 of these articles:

https://t-machine.org/index.php/2007/09/03/entity-systems-are-the-future-of-mmog-development-part-1/

I decided to implement an ECS myself, well aware that esper is a solid and long existing implementation, but I wanted to see how to implement it myself.

The base premise is: No OO and entities have no data.

So an entity is only a unique identifier. Components can be anything that can hold data, e.g. dataclasses

Workflow:

1. entity = create_entity()
2. add_component(entity, cid, component}
   ...
3. add_system(fkt, *cids)
   ...
4. in game loop run_all_systems(dt)

alternatively run_system(fkt, *cids)

If a system needs to modify components of other entities, these entities e.g. the player, need special eids so they can be queried from the registry.

use comps_of_eid(eid, *comps) for that. This way, a bullet component can substract health from a player entity.

Basic components are in the tinyecs.components package.

As of now, please look into the demos folder and read the documentation in the module. A longer howto will be added soon.
