The full ECS (Entity-Component-System) library. Support an Open Source Developer! :hearts: [](https://www.patreon.com/jojolepro) Composed of two smaller libraries: * [world_dispatcher](https://github.com/jojolepro/world_dispatcher): the `System` part of the ECS. * [entity_component](https://github.com/jojolepro/entity_component): the `Entity-Component` part of the ECS. Read the [documentation](https://docs.rs/planck_ecs). # Why would you use this ECS library? * Compatible with all platforms, including WASM! * Fast enough on *every* operation, not just iteration. * Minimal amount of dependencies. * Small code size. * Stable, tested, benchmarked, 100% completed. * Ability to handle system errors instead of crashing. * Convert both functions and closures into systems! * Safe: only 3 `unsafe` in total. (compared to hundreds in mainstream ECS libraries!) # Usage Add the following to you Cargo.toml file: ``` planck_ecs = "*" ``` Use it like so: ```rust use planck_ecs::*; fn main() { #[derive(Default)] pub struct A; let mut world = World::default(); let sys = (|comps: &mut Components, entities: &mut Entities| { let entity = entities.create(); comps.insert(entity, A); Ok(()) }).system(); let mut dispatch = DispatcherBuilder::new().add_system(sys).build(&mut world); dispatch.run_seq(&world).unwrap(); dispatch.run_seq(&world).unwrap(); dispatch.run_seq(&world).unwrap(); assert!(world.get::>().is_ok()); } ``` For more examples, see the two following repositories' example folders and documentation: * [world_dispatcher](https://github.com/jojolepro/world_dispatcher): information on systems, world and dispatchers. * [entity_component](https://github.com/jojolepro/entity_component): information on entities, components and joins. ### Maintainer Information * Maintainer: Jojolepro * Contact: jojolepro [at] jojolepro [dot] com * Website: [jojolepro.com](https://jojolepro.com) * Patreon: [patreon](https://patreon.com/jojolepro)
