FSit Continued

[!IMPORTANT] This is a community continuation of FSit by rvbsm, who has been unreachable for an extended period. This project exists solely to keep the mod alive and updated for newer Minecraft versions. It will be taken down immediately if the original author returns and contacts us. All credit for the original mod goes to rvbsm. Licensed under MIT.

Customizable server-side mod that allows players to sit, crawl, and ride each other. Client-side is supported too, it allows players to improve their experience by using client configuration and adding some client-side mod behaviour improvements.

[!NOTE] Inspired by GSit Spigot plugin.

Usage

Having this mod installed on the server is enough, players are not forced to have it to be able to use it.

However, installation on the client will bring some QoL improvements for players using this mod. Such as client configuration, better crawling, and key bindings.

Interacting with blocks

Interact with the topside of the block, that can be sat on, to start sitting on them.

Controlled with sitting.enabled.

Interacting with players

Interact with any player to start riding them. Clicking anyone in a riding stack will mount you on the topmost player.

Control angle difference with riding.max-yaw-difference.

Sneaking

Double sneak while looking down to sit right away.

Doing the same, but near the hole, will start crawling otherwise. (sneak-activation.prefer-crawl-in-tight-space)

Minimal pitch and the sneak window can be configured with sneak-activation.min-pitch-down and sneak-activation.window-ticks accordingly.

Commands

Pose commands:

• /sit — sit down where you stand
• /crawl — start crawling
• /lay — lay down (experimental)

Mod commands under /fsit:

• /fsit reload — re-read the configuration file (op only)
• /fsit mount-angle set <0..180> / /fsit mount-angle query — adjust riding.max-yaw-difference at runtime (op only)
• /fsit hands add <item|#tag> / remove / clear / reset / list — your own list of items that don't count as a "full" hand for the sit/mount checks. Defaults to torch and totem of undying, so you can hold them and still sit down. Available to every player, list is saved per-player.
• /fsit teleport <vanilla|disabled|enhanced> / /fsit teleport query — what happens to anyone sitting on you when you teleport (op only, server-wide):
  • vanilla — passengers ride along same-dimension, get left behind on cross-dimension teleport
  • disabled — passengers are dropped before the teleport
  • enhanced — passengers follow you, including across dimensions (recommended)

Key bindings (client)

Use key bindings to start sitting (default: RCtrl) or crawling (default: RAlt).

Key bindings have three modes: Hold, Toggle, and Hybrid. Hold and Toggle works the same as Vanilla. Hybrid is an in-between mechanic, that works as Toggle on single-use and as Hold on holding. The Hybrid window between Hold and Toggle can be configured from the Configuration Screen.

Configuration

As was stated before, players can use their own configurations if they have this mod installed on the client. Otherwise, server configuration will be used.

Configuration can be reloaded from the file with /fsit reload.

For clients, configuration can be modified with Mod Menu and YetAnotherConfigLib installed.

Default configuration file

# FSit configuration. Do not edit `version` by hand.
# On a dedicated server: `/fsit reload` re-reads this file.
# On the client: reloading local config requires a game restart.
version: 2

use-server-config: false

# Sitting on blocks (e.g. slabs, stairs).
sitting:
  enabled: true
  behavior: moveable
  centered: false
  blocks:
    - '#minecraft:slabs'
    - '#minecraft:stairs'
    - '#minecraft:logs'
    - '#minecraft:fences'
    - '#minecraft:walls'

# Riding other players (interact with a player to sit on their head).
# teleport-mode is server-wide (ops only). Possible values:
#   vanilla   -> let teleports happen as-is (passengers ride along same-dim,
#                stay behind on cross-dim — and may crash without 'enhanced')
#   disabled  -> drop passengers before any teleport
#   enhanced  -> carry passengers along, including across dimensions (recommended)
riding:
  enabled: true
  max-yaw-difference: 180
  teleport-mode: vanilla

# Double-sneak shortcuts for entering sit/crawl poses.
sneak-activation:
  enabled: true
  window-ticks: 10
  min-pitch-down: 60
  prefer-crawl-in-tight-space: true

# Commands.
#   true       -> enabled with default name
#   false      -> command is not registered
#   "name"     -> enabled with a custom name (e.g. lay: sleep)
# A server restart is required for command changes to take effect.
commands:
  root: true
  sit: true
  crawl: true
  lay: true

Options details

use-server-config

When set to true, forces all players (server) or player (client) to use server configuration.

Enabling this option will ignore client pose updates, leaving only server-to-client synchronization.

sitting.enabled

Allows sitting by interacting with blocks.

sitting.behavior

Controls sitting behaviour. Possible values: static, attached, moveable.

• static – does nothing, ignores everything;
• attached – seats will be discarded if they do not have any supporting block underneath;
• moveable – seats can be pushed by fluids, pistons, etc. Will start falling without a supporting block.

sitting.centered

Place seats in the centre of the block.

sitting.blocks

List of blocks and block tags that are available to interact with.

riding.enabled

Allows riding by interacting with other players.

riding.max-yaw-difference

When 1..180, controls the difference between players' horizontal facing angle to allow riding by interaction. 0 disables riding interactions, 180 removes the restriction entirely. Can also be changed at runtime with /fsit mount-angle set <0..180>.

riding.teleport-mode

Server-wide behavior for passengers when a player teleports. Possible values: vanilla, disabled, enhanced.

• vanilla – passengers ride along same-dimension, get left behind on cross-dimension teleport;
• disabled – passengers are dropped before the teleport;
• enhanced – passengers follow you, including across dimensions (recommended).

Can also be changed at runtime with /fsit teleport <vanilla|disabled|enhanced> (ops only).

sneak-activation.enabled

Enables double-sneak shortcuts for sitting and crawling.

sneak-activation.prefer-crawl-in-tight-space

Starts crawling instead of sitting if there is a hole nearby.

sneak-activation.min-pitch-down

Minimal required player pitch to start registering sneak actions. Where 90 is straight down, and -90 ignores player pitch.

sneak-activation.window-ticks

The window in ticks between sneaks to be recognized as double sneak action. Setting to 0 disables sneak actions.

commands.*

Per-command toggle. Each command (root, sit, crawl, lay) accepts:

• true – registered with the default name;
• false – not registered;
• "name" – registered with a custom name (e.g. lay: sleep).

A server restart is required for command changes to take effect.
