Compensates for network latency in fast-paced scenarios like Bedwars by extrapolating entity positions based on ping.

• Positional Extrapolation: Predicts where a player is moving based on their ping to the server, compensating for the visual delay inherent in multiplayer games.
• Hitbox Synchronization: Automatically applies the extrapolation during client-side combat raytracing. This means your crosshair interacts flawlessly with the visual model, even though the server thinks they are further behind.
• Rotation Extrapolation: Also predicts head and body rotations (Pitch & Yaw) so you can tell where high-latency players are aiming.
• Smoothed Velocity: Uses a moving average over a configurable history to calculate velocity, eliminating jitter compared to 1-tick velocity vectors.
• Teleport & Knockback Detection: Pauses extrapolation if an entity is moved an impossible distance instantly, preventing rubber-banding during events like ender pearl teleports.
• Interpolation Tuning: Reduces vanilla interpolation steps for extrapolated entities to provide more immediate visual feedback.
• In-Game Commands: Use /bedwarsantilag to tweak your configuration on the fly without restarting the game.

The mod will generate a config file in your config directory on the first run.

• extrapolationEnabled: (Default: true) Toggles the core logic.
• pingOffsetMs: (Default: 200) The assumed ping fallback if the server doesn't provide it via player info.
• maxExtrapolationDistance: (Default: 4.0) The absolute maximum distance (in blocks) the mod will visually displace a player.
• historyTicks: (Default: 5) Number of ticks to keep in the rolling average for velocity smoothing.
• disableOnTeleport: (Default: true) Prevents extreme snap-backs on sudden, large movements.
• targetInterpolationSteps: (Default: 2) The number of ticks vanilla Minecraft uses to blend entity movement (default is 3).
