Enum bevy::winit::UpdateMode

pub enum UpdateMode {
    Continuous,
    Reactive {
        wait: Duration,
    },
    ReactiveLowPower {
        wait: Duration,
    },
}

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

The App will update over and over, as fast as it possibly can, until an AppExit event appears.

Reactive

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.

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

ReactiveLowPower

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.

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

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.
