Expand description

A collection of systems associated directly to a Game as opposed to a Session.

Fields§

Game systems that are run before sessions are run.

§after: Vec<Box<dyn FnMut(&mut Game) + Send + Sync>>

Game systems that are run after sessions are run.

§after_session: HashMap<Ustr, Vec<Box<dyn FnMut(&mut Game) + Send + Sync>>, BuildHasherDefault<FxHasher>>
