What is Entei's Inventory Manager?
Running a Minecraft server often means juggling multiple worlds, gamemodes, and player expectations. Entei's Inventory Manager is a powerful Bukkit plugin designed to give you full control over what inventory each player sees when they hop between worlds or switch gamemodes. Instead of forcing every world to share a single inventory, this tool lets you create per-world, per-gamemode, or even shared-world inventory setups with surgical precision. It saves everything from enchanted gear and custom lore to books, potion effects, health, hunger, and experience levels, so nothing gets lost in transition.
Key Features That Set It Apart
The plugin goes far beyond simple inventory separation. Here is what makes it a must-have for server admins who want to craft unique player experiences:
- Human-readable save files that can be edited manually or modified by other plugins.
- Full support for all item data: enchantments (including unsafe ones), custom names, lore, damage values, and written books.
- Per-world inventories or combined world inventories with exclusions — mix and match as you like.
- Gamemode-specific inventories that save and load automatically when a player changes gamemode.
- Extra double-chest sized inventories per player, accessible via command or permission.
- Optional saving of health, hunger, hunger saturation, potion effects, and experience alongside inventories.
- Item ownership tracking to prevent stealing, with configurable auto-claim and theft rules.
- An in-game permission system that lets players grant others view or edit access to their inventories, ender chests, and extra chests.
How the Plugin Handles Inventory Data
When a player logs in or teleports to a different world, Entei's Inventory Manager checks your configuration and loads the appropriate inventory. If you set worldsHaveSeparateInventories to true, each world gets its own save file. Combine that with loadByGameMode and you can have survival, creative, and adventure inventories stored independently for every world. The plugin saves data in a readable YAML format, which means you can open the files and tweak them by hand if needed. It even backs up the player's normal inventory when necessary, so returning to a previous world restores exactly what they left behind.
The system also handles edge cases gracefully. For instance, if a player somehow obtains creative mode on an adventure map, their survival inventory is safely tucked away and the creative inventory is loaded. This makes it perfect for adventure servers, minigame hubs, or any setup where inventory continuity would break immersion.
Commands and Permissions at a Glance
Admins and players get a robust set of commands to interact with the plugin. Here are the core commands:
/eim— master command for info, saving, and reloading the configuration./setmaxhealth— adjust a player's maximum health (requires operator)./view— view your own or another player's inventory, ender chest, or extra chest for a specific gamemode./invperm— grant or revoke permission for others to view or edit your inventories.
Each command has its own permission node, giving you fine-grained control. The /invperm command is especially handy for cooperative play, letting you share resources without dropping items on the ground.
Configuration: Tailoring the Plugin to Your Server
The config.yml file is where the magic happens. You can define lists of worlds that share inventories, decide whether gamemodes are separated, and toggle features like experience management, health saving, and potion effect updates. A particularly neat option is the 30-second potion effect auto-save, which prevents players from glitching effect durations. You can also activate item ownership to stamp every item with the player who obtained it, and then decide if stealing is allowed or if items must be claimed with a command.
For server owners who want a hassle-free setup, the plugin can be installed in minutes. While you can always drop the JAR files into your plugins folder manually, many admins now prefer using a modern launcher to handle installations. If you use the foxygame.net launcher, you can browse and install Entei's Inventory Manager directly from its menu, saving time and ensuring you always have the latest version alongside its required library.
Installation and Compatibility Notes
Entei's Inventory Manager requires Entei's Plugin Library to function, which is bundled with the download. It also optionally supports Vault for the advanced /invperm command. Because the plugin intercepts and manages inventory loading, it may conflict with other inventory-related plugins, so test it in a staging environment first. The developer actively maintains the project and welcomes feedback, so you can expect updates that address compatibility issues.
The plugin is built on a custom InventoryAPI that handles all the heavy lifting, and the source code is available for those who want to audit or contribute. If you run into trouble, enabling debug messages in the config can help you trace what is happening, though it is best to leave that off on busy servers to avoid performance hits.
Conclusion
Entei's Inventory Manager fills a gap that vanilla Minecraft leaves wide open: the ability to give each world and gamemode its own persistent inventory without breaking the game's item system. From adventure maps that need controlled loadouts to multi-world survival servers where players expect their gear to follow them, this plugin delivers flexibility and reliability. Its readable save files, extensive command set, and optional item ownership features make it a standout choice for admins who want to craft a polished player experience. Whether you are running a small private server or a large network, Entei's Inventory Manager is a tool that deserves a spot in your plugins folder.
