Oggvik's Inventory Freeze

Oggvik's Inventory Freeze

A simple Minecraft Forge mod written in Java that lets you "freeze" configurable inventory slots globally for all players. It's main purpose is to be used on a server (e.g. an RP server with roleplaying events where you'd want to limit the number of inventory slots for the sake of added immersion) or as part of modpacks (e.g. ultra hardcore survival ones).

The mod provides a single command to enable globally "freezing" specific inventory slots:

/inventory-lock [true/false]

DESIGN

• 🪷 Very clean & simple code written in Java
• 🔒 Server-side watchdog to prevent item duping exploits & item deletion
• 🚀 Could easily be ported to newer Minecraft/Forge versions
• 😎 Custom item pickup logic to prevent picking up items into "frozen"/"locked" inventory slots
• 🎨 GUI effects (frontend) code isolated from rest of the program's internal logic (backend)
• 🩷 Tiny size (currently a mere ~330 KB)
• 👋 Tested to work in both survival and on multiplayer with many people / on a server

FUNCTIONALITY

• 🧊 "Freeze" parts of the players' inventories while /inventory-lock true is set.
• ❌ When /inventory-lock is true players cannot put in, take out, or delete items from their own "frozen"/locked inventory slots.
• 👗 Only freezes the inventory slots configured. Aka doesn't affect inventory slots such as chests, other mods (e.g. backpacks), armor, capes, and other custom inventory slots related to cosmetics.
• 🖼️ The slots that are frozen will be indicated with a gray transparent square overlay (indicator appearance might be altered in future versions).
• 🪽 Automatically unfreezes the inventories of players when they switch to creative mode, then re-freezes them again if they exit creative mode while the /inventory-lock is true.
• 🔢 The inventory slots to be frozen are to be easily configurable by server admins.
• [WIP] 🧑‍🤝‍🧑 Exclude specific players from the /inventory-lock. For example whoever is hosting an RP event on a server or playing an actor could be excluded from the /inventory-lock for the duration of that time.
