Crate dces

DCES

DCES is a library that provides a variant of the entity component system.

Features:

• Filter and sort entities for systems
• Define priorities (run order) for systems

The library is still WIP. API changes are possible.

Example

extern crate dces;
use dces::prelude::*;

struct Name { value: String }

struct PrintSystem;

impl System for PrintSystem {
    fn run(&self, entities: &Vec<Entity>, ecm: &mut EntityComponentManager) {
        for entity in entities {
            if let Ok(comp) = ecm.borrow_component::<Name>(*entity) {
                println!("{}", comp.value);
            }
        }
    }
}

fn main() {
    let mut world = World::new();

    world.create_entity().with(Name { value: String::from("DCES") }).build();
    world.create_system(PrintSystem).build();

    world.run();
}
