Enum bevy_winit::UpdateMode
source · pub enum UpdateMode {
Continuous,
Reactive {
wait: Duration,
},
ReactiveLowPower {
wait: Duration,
},
}
Expand description
Determines how frequently an App
should update.
Note: This setting is independent of VSync. VSync is controlled by a window’s
PresentMode
setting. If an app can update faster than the refresh
rate, but VSync is enabled, the update rate will be indirectly limited by the renderer.
Variants§
Continuous
Reactive
The App
will update in response to the following, until an
AppExit
event appears:
wait
time has elapsed since the previous update- a redraw has been requested by
RequestRedraw
- new window or raw input events have appeared
- a redraw has been requested with the
EventLoopProxy
Fields
wait: Duration
The approximate time from the start of one update to the next.
Note: This has no upper limit.
The App
will wait indefinitely if you set this to Duration::MAX
.
ReactiveLowPower
The App
will update in response to the following, until an
AppExit
event appears:
wait
time has elapsed since the previous update- a redraw has been requested by
RequestRedraw
- new window events have appeared
- a redraw has been requested with the
EventLoopProxy
Note: Unlike Reactive
, this mode will ignore events that
don’t come from interacting with a window, like MouseMotion
.
Use this mode if, for example, you only want your app to update when the mouse cursor is
moving over a window, not just moving in general. This can greatly reduce power consumption.
Fields
wait: Duration
The approximate time from the start of one update to the next.
Note: This has no upper limit.
The App
will wait indefinitely if you set this to Duration::MAX
.
