A New Super Virtual Chest

A server-side virtual chest mod for Fabric. Create public or private virtual chests that store items persistently without needing any client-side installation.

English: The main reason I created this mod is that there wasn't an up-to-date virtual chest mod for newer Minecraft versions that allows creating multiple persistent chests. I needed a simple, server-side solution for my own server, so I built it.

中文: 我制作这个模组的主要原因是没有新版本的可创建多个且持久化的虚拟箱子模组。我自己的服务器需要一个简单的纯服务端方案，于是就有了它。

Q&A

Q: There are already other virtual chest mods. Why did you make another one?
A: While similar mods exist, none of them supported Minecraft 1.21.11+ when I started this project.

Q: Why did you upload the source code JAR?
A: I don't have a GitHub account and I'm not familiar with how to use it.

📦 Features

• 🗃️ Virtual Chests – Create chests that are not tied to any physical block.
• 🌍 Public & Private – allplayer creates a public chest anyone can open. Use a player name to create a private chest only that player (and admins) can access.
• ⏳ Delayed Public Deletion – When a non-admin deletes a public chest, it enters a 3‑in‑game‑day waiting period before being permanently removed. Anyone can cancel the deletion during this time.
• ✅ Instant Admin Actions – Players with the nsvc_admin tag (or console/command blocks) can create, open, and instantly delete any chest.
• 💾 Persistent Storage – All chest contents are saved to disk inside the world folder and survive server restarts.
• 🌐 Multi-language Support – English and Simplified Chinese are included. (Your client language determines which is shown.)
• 🖥️ Pure Server‑side – No client mod required! Players connect with a vanilla client and still see the normal chest GUI.

⌨️ Commands

All commands use the prefix/NSvc.

📝 Create a Chest

/NSvc <target> create <name> [small|large]

• <target> – allplayer for a public chest, or an online player name for a private chest.
• <name> – A unique name for the chest (e.g., community_farm).
• [size] – small (27 slots) or large (54 slots). Defaults to large.

Examples: /NSvc allplayer create PublicStorage large /NSvc Steve create StevePrivate small

📂 Open a Chest

/NSvc <target> open <name>

Opens the virtual chest GUI.
Non-admin players can only open public chests or their own private chests.

Example: /NSvc allplayer open PublicStorage

🗑️ Delete a Chest

/NSvc <target> delete <name> [close]

• Without close – Starts deletion (public chests go into a 3‑day waiting period; private chests ask for confirmation).
• With close – Cancels a pending deletion.

Examples: /NSvc allplayer delete PublicStorage /NSvc allplayer delete PublicStorage close

📋 List Chests

/NSvc <target> list

Shows all chests belonging to the target (allplayer for public chests, or a player name for private chests).
Admins see all private chests; normal players only see their own.

🛡️ Admin Permissions

This mod does not use a separate permission file.
Instead, admins are identified by the nsvc_admin tag.

🏷️ Granting Admin

Run this command in the server console or as an existing admin: /tag <player> add nsvc_admin

❌ Removing Admin

/tag <player> remove nsvc_admin

👀 Checking a Player's Tags

/tag <player> list

💡 Tip: The console and command blocks always have full admin permissions and do not need the tag.

📁 Data Storage

Virtual chest data is saved in the world folder as nsvc_virtualchests.dat.
This file is created automatically and is compatible with world backups.

🌍 Language Support

The mod automatically uses your Minecraft client language.
Currently supported languages:

• English (en_us)
• Simplified Chinese (zh_cn)
