A Roadmap to Entity Relationships #10
Description
I've been using Sander Mertens articles to implement relationships. I've implemented these in the basic sense but they also have an article that describes a roadmap for a more complete implementation.
- Components as entities - Python objects natively support what this is trying to do
- Callbacks on state changes #6
- Support relationship pairs in archetype storage
- Relationship components - Already added
- Wildcard queries - Half of this is implemented
- The component index
- Cleanup
- Cleanup traits
- Multi-source queries
- Relationship traversal
- Query cache revalidation
- Breadth first traversal
- Uncached queries
- Multi component observers
- Event propagation
- Empty table optimization
- Garbage collection
- Rule engine
- Exclusive relationships - Already added as an alternative syntax for relationship access
- Inheritance #12
- Query DSL - Probably not needed for a Python library
I don't know if I'll ever complete this. Some of these might be too slow when implemented in pure-Python and if I were to make a C extension then I may as well just port Flecs itself to Python.
It's clear that these features will be incredibly useful once added. At the very least I should keep all of these in mind as I work on this module.
