Usage
You're better off importing the entire library.
use bevy_state_stack::*;
Add the state enum into the app.
app.add_state_stack(AppState::Menu)
Add different systems to the app.
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.
fn start_game(mut c: Commands) {
c.insert_resource(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::<AppState>::Pop);
}
