Struct bevy::prelude::Real

pub struct Real { /* private fields */ }

Real time clock representing elapsed wall clock time.

A specialization of the Time structure. For method documentation, see Time<Real>.

It is automatically inserted as a resource by TimePlugin and updated with time instants according to TimeUpdateStrategy.

The delta() and elapsed() values of this clock should be used for anything which deals specifically with real time (wall clock time). It will not be affected by relative game speed adjustments, pausing or other adjustments.

The clock does not count time from startup() to first_update() into elapsed, but instead will start counting time from the first update call. delta() and elapsed() will report zero on the first update as there is no previous update instant. This means that a delta() of zero must be handled without errors in application logic, as it may theoretically also happen at other times.

Instants for startup(), first_update() and last_update() are recorded and accessible.
