Eccles

Eccles is a simple implementation of an Entity Component System in Rust, inspired by rust_ecs and ecs-rs. It uses macros to make the component list fast and easy to access.

The macro

You use the world! macro to construct a world to put entities, components and systems on. Its syntax is:

 world!{
    name: (The name of the world),
    components: {
        (list name for using as a field on the world) => (component type),
        positions => Position
    },
    processors: {
        (processor name for using as a field on the world) => (processor type with Default impl) for [(list names to give to the processors)],
        render => Render for [sprite, pos]
    }
 }
