Movement & stances

How to play

Move with the movement keybindings (W A S D + arrows by default). Three stances change height, eye level and speed:

Stance	Height	Eye offset	Speed
Standing	HEIGHT_STANDING	EYE_OFFSET_STANDING	SPEED_STANDING
Sneaking	HEIGHT_SNEAKING	EYE_OFFSET_SNEAKING	SPEED_SNEAKING
Crawling	HEIGHT_CRAWLING	EYE_OFFSET_CRAWLING	SPEED_CRAWLING

Exact values: player constants.

• Fly mode and speed boost are toggleable (bindable keys). Fly disables gravity for that player; Y stays server-authoritative otherwise.
• /mount mounts or dismounts the vehicle you are targeting — see Vehicles.

Movement is the only action that is not a slash command: the client sends MoveIntent, the server validates against AABB physics in core, and replies PlayerUpdate. The client predicts XZ locally and soft-corrects.

Camera / view modes

view_toggle (F by default) cycles the camera; /view_mode <MODE> jumps straight to one (ignoring the preference filter below). A notification shows the current mode on every change. The chase camera pulls in when a solid block sits between it and the player — the chunk mesh has no inward faces.

Mode	Camera
FIRST_PERSON	eyes, full body drawn
THIRD_PERSON	level chase camera, rotate_left/right turn it
FIRST_PERSON_NO_ARMS	eyes, arms hidden
THIRD_PERSON_ORBIT	chase camera orbits on the mouse, heading on the turn keys, wheel zooms
THIRD_PERSON_ORBIT_CURSOR	as orbit but pointer is free: the OS cursor aims block interaction, left-click breaks/places, Alt+left-drag orbits, the camera lifts over the player with the pitch

In both orbit modes rotate_up / rotate_down (Alt+Arrow Up/Down) change the pitch. Preferences → Game hides individual modes from the view_toggle cycle (FIRST_PERSON always stays).

Configuration

Stance dimensions and speeds are centralised in PlayerConstants (core). They can be overridden at server startup under the player: block of server.yaml:

player:
  heightStanding: 1.8
  heightSneaking: 1.5
  heightCrawling: 0.6
  width: 0.6

A skin's <name>.yaml may also set a first-person camera anchor (eyes: {x,y,z}) and firstPersonHiddenBones; skins without a yaml fall back to the stance eye offsets above.
