use bevy_ecs::prelude::{IntoSystemConfigs};
use bevy_cronjob::schedule_passed;
fn main() {

MinimalPlugins.set(ScheduleRunnerPlugin::run_loop(Duration::from_secs_f64(
1.0 / 60.0,
))),
)
.add_plugins(LogPlugin::default())
.add_systems(Update, print_per_5_sec.run_if(schedule_passed("0/5 * * * * *")))
.add_systems(Update, print_per_min.run_if(schedule_passed("0 * * * * *")))
.add_systems(Update, print_per_hour.run_if(schedule_passed("0 0 * * * *")))
.run()
}
fn print_per_5_sec() {
info!("print every 5 sec")
}
fn print_per_min() {

Expression
the scheduling expression is base on cron
sec | min | hour | day of month | month | day of week | year |
---|---|---|---|---|---|---|
* | * | * | * | * | * | * |
0-59 | 0-59 | 0-23 | 1-23 | 1-12 | 1-7 | 1970-2100 |
Time is specified in UTC. Note that the year may be omitted.
Comma separated values such as 1,2,3
are allowed. For example, a schedule of 0,15,30,45 * * * * *
