ViveMonkeCraft

Minecraft 1.21.4-1.21.6 · Fabric · QuestCraft / Vivecraft 1.2.x Only

What It Does

ViveMonkeCraft brings Gorilla Tag-style locomotion to QuestCraft/Vivecraft 1.2.x. Grab walls, floors, and ceilings with your VR controllers, then physically push and pull yourself through the world. Releasing your grip while moving quickly converts your momentum into a jump.

Intended Experience

ViveMonkeCraft is inspired by Gorilla Tag locomotion but adapted for Minecraft's physics, collision system, and world scale. As a result, movement will feel similar in concept but not identical to Gorilla Tag.

✨ Features

• Gorilla Tag-style hand-grab locomotion
• Physical climbing, swinging, and wall push-off
• Momentum-based throw/jump on release
• Two physics modes: stable Speed-based (default) and GT-Physics (Beta), a faithful anchor-based port of the official GorillaLocomotion algorithm
• Real Monke: shrink your collision box to fit through 1-block tunnels (client + server enforced)
• Monke Model: render players legless with a tunable torso/arms/head, synced so everyone with the mod sees it
• Hand-model clamping: your hands plant on the block surface instead of sinking in
• Step assist: instant step-up onto ledges, or the classic upward boost
• Ice wall & ice floor physics (with an experimental "ice floor acts like ice wall" toggle)
• Adjustable gravity (zero-G capable) and air/ground/floor friction
• VR comfort vignette + grip smoothing (motion-sickness reduction)
• Optional lowered camera so your hand hitboxes line up with your real hands
• Hand-hitbox markers (green/red) for learning the grab range
• Barrier blocks are invisible to the mod, so admins can wall off areas
• Built-in presets: Tutorial, Default, Long Arms, Zero Gravity, Speed Run
• Configure every setting in-game with /vmc set, no Mod Menu/Cloth needed
• Auto-applies the Default preset on first launch

🖥️ Compatibility

• Minecraft 1.21.4
• Fabric Loader 0.19.3
• QuestCraft
• Vivecraft 1.2.x

Not compatible with:

• Non-VR gameplay other than seeing your friends without legs
• Other Vivecraft major versions yet

The mod automatically disables itself when VR is not active.

🎮 Platform notes

• QuestCraft / Vivecraft 1.2.x only: On non-VR clients the mod detects VR is inactive and does nothing except show other player models without legs.
• Cloth Config and Mod Menu are optional soft dependencies. Without them, use /vmc set or edit the .properties file.

Multiplayer

• Singleplayer & "Open to LAN" / Essential works with just this client mod; a LAN host automatically authorizes guests, no extra files for anyone.
• Dedicated servers: the mod stays off until the server installs the companion ViveMonke server mod. This is a deliberate server-side opt-in, so it can't be used on servers that haven't allowed it.
• The server mod is on my GitHub page/in Source.

🧊 Ice Physics

• Ice is grabbable on all faces but too slippery to climb. You slide off rather than stick.
• Ice walls/ceilings can be pushed off for momentum, but not used as reliable climbing surfaces.
• Ice is frictionless with a speed cap of player speed × 0.4.
• Experimental: an option to make ice floors behave like ice walls (pure push-off, no glue).

🛠️ Configuration

Three ways to change settings. All write to the same .minecraft/config/vivemonkecraft.properties file:

1. Mod Menu + Cloth Config: full slider/toggle screen from the Mods list, organized into Presets, Movement, GT-Physics, Reach & Body, Jump & Gravity, and Visual pages. Includes the preset dropdown.

2. /vmc set <setting> <value>: change any setting by name in-game (tab-completes). Works without Mod Menu or Cloth Config.

3. Edit the .properties file directly, then run /vmc reload (or toggle the mod off/on).

Presets: Tutorial (easiest to move), Default, Long Arms, Zero Gravity, Speed Run. Selectable in-game; the Default preset is applied automatically on first launch.

🥽 QuestCraft Installation

• Use the QuestCraft built-in mod loader.
• With files: use SideQuest and drop this mod into the mods folder.
