Struct veloren_common::comp::presence::ViewDistance

pub struct ViewDistance {
    direction: Direction,
    last_direction_change_time: Instant,
    target: Option<u32>,
    current: u32,
}

Distance from the Presence from which the world is loaded and information is synced to clients.

We limit the frequency that changes in the view distance change direction (e.g. shifting from increasing the value to decreasing it). This is useful since we want to avoid rapid cycles of shrinking and expanding of the view distance.

Fields

direction: Direction

last_direction_change_time: Instant

target: Option<u32>

current: u32

Implementations

impl ViewDistance

const TIME_PER_DIR_CHANGE: Duration = _

Minimum time allowed between changes in direction of value adjustments.

pub fn new(start_value: u32, now: Instant) -> Self

pub fn current(&self) -> u32

Returns the current value.

pub fn update(&mut self, now: Instant)

Applies deferred change based on the whether the time to apply it has been reached.

pub fn set_target(&mut self, new_target: u32, now: Instant)

Sets the target value.

If this hasn’t been changed recently or it is in the same direction as the previous change it will be applied immediately. Otherwise, it will be deferred to a later time (limiting the frequency of changes in the change direction).
