Module schedule

Checks for adding systems to a disallowed schedule.

• fixed_update_schedule: Disallows using the FixedUpdate schedule.
• update_schedule: Disallows using the Update schedule.

Motivation

Often, projects will prefer certain systems be in either the Update or FixedUpdate schedule. These two lints are useful for denying an unwanted schedule throughout entire modules. For example, a project may deny the Update schedule in a module that only contains physics logic, or deny the FixedUpdate schedule in a module that likewise contains only rendering code.

Example

mod physics {
    #![warn(bevy::update_schedule)]

    fn plugin(app: &mut App) {
        // This isn't allowed, use `FixedUpdate` instead!
        app.add_systems(Update, my_system);
    }

    fn my_system() {
        // ...
    }
}

Use instead:

mod physics {
    #![warn(bevy::update_schedule)]

    fn plugin(app: &mut App) {
        app.add_systems(FixedUpdate, my_system);
    }

    fn my_system() {
        // ...
    }
}
