GuestMode

👻 GuestMode — Visible Spectators for Your World

GuestMode is a lightweight plugin for Folia (Minecraft 1.21+) that lets your friends join your world as visible spectators — exploring freely without affecting gameplay.

Players in guest mode are completely isolated from the world around them:

• Cannot break or place blocks
• Cannot use doors, chests, beds, crafting tables, or any interactive blocks
• Cannot attack, take damage, pick up items, or collect XP
• Cannot interact with mobs, ride entities, or throw potions and projectiles
• Are ignored by all mobs (but mobs can still look at them)
• Cannot push or move any entities — including players (but normal players can still nudge guests)
• Can fly freely for complete exploration freedom (future updates may add per-player settings)

Guests remain visible and can explore the world freely, but they cannot influence it in any way.

🆕 New in 1.3

• You can now change guest permissions directly in the config file — the full configuration is included at the bottom of this page.

---

🆕 New in 1.2

• Guests are not counted for sleeping – only real players need to sleep to accelerate the night.
• Phantom targeting fixed – phantoms no longer spawn based on guest players.
• World pause logic – the world is automatically paused when only guests (or no one) are online (future updates may allow disabling this setting in the config)

---

🤝 Compatibility

Fully compatible with RealisticSleep (Folia) — guest players are automatically ignored by sleep checks, so only real players are required to sleep for the night to pass.

🧩 Configuration

# ===============================
#  GuestMode configuration guide
# ===============================
#
# === PLAYER LISTS ===
# Two lists control who is a GUEST and who is NORMAL:
#
#   - guests: players treated as GUESTS.
#   - except: players treated as NORMAL (never guests).
#
# Special token:
#   - "[all]" (must be quoted!) — a global switch.
#
# Modes
# -----
# 1) Individual mode (no "[all]" anywhere)
#    - Only players listed under `guests` are guests.
#    - Players in `except` are always normal.
#
# 2) Global guests mode (put "[all]" in `guests`)
#    - Everyone is a guest EXCEPT the names listed in `except`.
#    - `except` is the allow-list for being normal in this mode.
#
# 3) Global except mode (put "[all]" in `except`)
#    - Everyone is normal EXCEPT the names listed in `guests`, who become guests.
#    - `guests` is the allow-list for being a guest in this mode.
#

# === PLAYER MODE LISTS ===

  - Player1

# Prevents guests from pushing other players/entities
# Guests phase through collisions without affecting normal players
anti_push:
  enabled: true # tested
  
  # AABB padding - safety margin around hitboxes (in blocks)
  # Larger = more separation, but may feel "floaty"
  aabb_padding: 0.10 # Set to 0.65 so that guests are always one block apart from players and other entities (the player can dig without restrictions)

  # Top epsilon - gap when landing on entities (in blocks)
  top_epsilon: 0.05
  
  # Detection radius - how far to check for nearby entities (in blocks)
  detection_radius: 3.0
  
  # Safe gap - minimum space maintained between hitboxes after push (in blocks)
  safe_gap: 0.05
  
  # Max resolution iterations - attempts to resolve complex overlaps
