Struct TimeSyncConfig 

pub struct TimeSyncConfig {
    pub window_size: usize,
}

Configuration for time synchronization behavior.

The time sync system tracks local and remote frame advantages over a sliding window to calculate how fast/slow this peer should run relative to the other peer(s).

Example

use fortress_rollback::TimeSyncConfig;

// For more responsive sync (may cause more fluctuation)
let responsive_config = TimeSyncConfig {
    window_size: 15,
    ..TimeSyncConfig::default()
};

// For smoother sync (slower to adapt to changes)
let smooth_config = TimeSyncConfig {
    window_size: 60,
    ..TimeSyncConfig::default()
};

Fields

window_size: usize

The number of frames to average when calculating frame advantage. A larger window provides a more stable (less jittery) sync but is slower to react to network changes. A smaller window reacts faster but may cause more fluctuation in game speed.

Default: 30 frames (0.5 seconds at 60 FPS)

Implementations

impl TimeSyncConfig

pub fn new() -> Self

Creates a new TimeSyncConfig with default values.

pub fn responsive() -> Self

Configuration preset for responsive synchronization.

Uses a smaller window to react quickly to network changes, at the cost of potentially more fluctuation in game speed.

pub fn smooth() -> Self

Configuration preset for smooth synchronization.

Uses a larger window to provide stable, smooth synchronization, at the cost of slower adaptation to network changes.

pub fn lan() -> Self

Configuration preset for LAN play.

Uses a small window since LAN connections are typically stable.

pub fn mobile() -> Self

Configuration preset for mobile/cellular networks.

Uses a very large window to smooth out the high jitter and variability typical of mobile connections. This prevents constant speed adjustments that would feel jarring to players.

Trade-off: Slower adaptation to actual network condition changes, but much smoother gameplay during normal mobile network variance.

pub fn competitive() -> Self

Configuration preset for competitive/esports scenarios.

Uses a smaller window for faster adaptation to network changes, prioritizing accurate sync over smooth speed transitions. Assumes good, stable network conditions.
