Usage

You're better off importing the entire library. rust use bevy_state_stack::*;

Add the state enum into the app. rust app.add_state_stack(AppState::Menu)

Add different systems to the app. rust app.add_system_on_enter(AppState::Menu, setup_menu) .add_system_on_exit(AppState::Menu, despawn::<Menu>) .add_system_on_enter(AppState::Map, setup_map) .add_system_on_update(AppState::Map, pause) .add_system_on_update(AppState::Encounter, pause) .add_system_set_on_update( AppState::Menu, SystemSet::new() .with_system(resume) .with_system(start_game), )

You can set, push, or pop the state on top of the stack by inserting the Stack resource. ```rust fn startgame(mut c: Commands) { c.insertresource(Stack::Set(AppState::Map)) }

fn pause(mut c: Commands) { c.insert_resource(Stack::Push(AppState::Menu)) }

fn resume(mut c: Commands) { c.insert_resource(Stack::::Pop); } ```
