Ecspanse is not a game engine, but a flexible foundation for managing state and building logic, with features like:
- flexible queries with multiple filters
- dynamic bidirectional relationships
- versatile tagging capabilities
- component templates
- system event subscriptions
- asynchronous system execution

New release v0.2.0
Introduces Component and Event Templates for simplifying the creation of related components and events.
Adds a new query
Ecspanse.Query.fetch_tagged_component/2that returns an entity’s component by a list of tags. Attention, it is the logic implementation duty to ensure that no more than one component is returned, or it will raise an error.Introduces also some small breaking changes: the Timer Component and Event are now Templates.
use Ecspanse.Component.Timeranduse Ecspanse.Event.Timershould be replaced withuse Ecspanse.Template.Component.Timeranduse Ecspanse.Template.Event.Timer.D4no0
I don’t understand from reading the documentation and the article, what do you mean it’s not a game engine?
What kind of problems it actually solves, like realtime synchronization?

You might find information about ECS here…
While it’s new in OOP video game, it’s kind of natural in FP
iacobson
Ecspanse is a state management library. It also runs the “game loop” and offers some built-in functionality like timers.
what I mean by “it’s not a game engine” is that has no functionality for rendering, controls/input, physics, assets, GUI, etc. So you will need to combine it with some other technology if you want to build anything user-facing.

Thank You for your lib, I am going to try it for some games that I have in mind
iacobson
When you will have a working prototype, please paste it here. I’m extremely curious about what kind of games people think to build with Elixir.
kokolegorille
Will do… currently I am thinking of using React and Three, or Three fiber for the front end and controls, Phoenix for socket and clients communication, and ECS for managing game state.
But it might take some time
D4no0
Is it though? are we talking about the concepts used behind unity engine?
kokolegorille
Yes, exactly, that’s how they could achieve a demo called something like 1000 cities… I don’t remember the name, but the demo I do
D4no0
Isn’t that just a basically just a change from inheritance to composition? I mean that’s nice, however I don’t think erlang VM can fit in this theme by design,
