pub enum TimeUpdateStrategy {
    Automatic,
    ManualInstant(Instant),
    ManualDuration(Duration),
}
Expand description

Configuration resource used to determine how the time system should run.

For most cases, TimeUpdateStrategy::Automatic is fine. When writing tests, dealing with networking or similar, you may prefer to set the next Time value manually.

Variants§

§

Automatic

Time will be automatically updated each frame using an Instant sent from the render world via a TimeSender. If nothing is sent, the system clock will be used instead.

§

ManualInstant(Instant)

Time will be updated to the specified Instant value each frame. In order for time to progress, this value must be manually updated each frame.

Note that the Time resource will not be updated until TimeSystem runs.

§

ManualDuration(Duration)

Time will be incremented by the specified Duration each frame.
