What Is the Backpack Display Mod?
Inventory management in Minecraft can quickly become a puzzle of shulker boxes, storage drawers, and specialized backpacks. You stash valuable resources inside containers, but remembering exactly what is where often means breaking blocks or opening every single item. The Backpack Display mod solves this frustration by adding a sleek tooltip that reveals the contents of any container item right when you hover over it in your inventory. Whether you are hauling rare ores in a purple shulker box or organizing your farm’s output with Forestry backpacks, the mod gives you an instant peek inside without any extra clicks.
Core Features and Out-of-the-Box Support
This client-side mod works straight away with many popular storage items. You don't need to write any custom rules to enjoy its benefits. Right after installation, you'll see tooltips for:
- All vanilla shulker boxes (including dyed variants)
- Storage Drawers mod drawers (basic and compact)
- Forestry backpacks (miner, digger, forester, and more)
The tooltip appears automatically when you hover over the container item, showing a neat grid of the stored items and their counts. This visual feedback transforms how you browse chests full of shulker boxes or scroll through your backpack collection. No more guessing which box holds your diamonds.
Configurable Options to Suit Your Playstyle
The mod respects that every player has a different workflow. Inside the config file, you can fine-tune exactly how and when the tooltip appears. Here are the main settings you can adjust:
- Item filtering: Choose which items trigger the tooltip. You can limit it to specific mod containers or even add your own custom entries.
- Tooltip position and color: Move the display to any corner of the screen and pick a background tint that matches your UI theme.
- Keybind toggle: By default the tooltip shows on hover, but you can set it to only appear while holding a chosen key, keeping your screen uncluttered during normal play.
These options are especially handy for modpack creators who want a consistent experience across dozens of container types.
Adding Custom Container Items with Display Rules
The true power of Backpack Display lies in its rule-based system. If you use a mod that adds its own storage items not covered by default, you can teach the mod how to read their contents. The configuration uses a simple format: <modID>:<itemID>[:meta]#<rule type>#<rule definition>. The metadata part is optional and supports comma-separated values and ranges like 1,2,5-8.
List Rule
Use this when the stored items are kept inside an NBT list or compound. The rule definition includes a path to the list, an optional path to the item stack within each list entry, and an optional path to a separate count value. For example, the built-in support for a purple shulker box is simply:
minecraft:purple_shulker_box#list#BlockEntityTag.Items
The mod then iterates over every element in the Items list and extracts the item and its count.
Single Rule
Some containers store only one item at a fixed NBT path, with the count possibly stored elsewhere. The single rule handles these cases. You provide the path to the item stack and, if needed, a separate path to the count. For Storage Drawers basic drawers, the config lines look like this:
storagedrawers:basicdrawers:0#single#BlockEntityTag.Drawers.0.Item;BlockEntityTag.Drawers.0.Count
When the count isn’t stored directly but can be calculated, you can chain arithmetic operators (+ - * / ^ %) followed by paths. For compact drawers, the mod divides the drawer’s total count by the item’s conversion rate to show the real number of items. The config uses lines like:
storagedrawers:compdrawers#single#BlockEntityTag.Drawers.Items.0.Item;BlockEntityTag.Drawers.Count;/BlockEntityTag.Drawers.Items.0.Conv
CraftTweaker Integration for Advanced Users
Starting from version 1.3, you can write fully custom display logic using CraftTweaker scripts. This is perfect for modpacks where items need dynamic tooltips based on complex conditions. The function receives the hovered item stack and must return an array of item stacks to show. Remember to wrap your script in #sideonly client because the mod runs exclusively on the client side.
A creative example: you can make every wood log display a crafting table and its plank output in the tooltip. The script imports mods.backpackdisplay.BackpackDisplay and uses addBackDisplay with an IIngredient and a function. Items from CraftTweaker rules always appear before those from normal config rules, giving you full control over the order.
When you're ready to add this quality-of-life improvement to your game, getting it set up is straightforward. For those who prefer a streamlined modding experience, the foxygame.net launcher provides a convenient, flexible, and modern Minecraft launcher where you can download mods like Backpack Display right from the menu, automatically handling installation and version compatibility.
Why Backpack Display Belongs in Every Inventory
The mod eliminates the tedious back-and-forth of opening containers just to check their contents. It respects your screen real estate with configurable positioning and keybinds, and it grows with your modpack thanks to the extensible rule engine. Whether you stick with vanilla shulker boxes or dive into complex storage networks, Backpack Display keeps your inventory transparent and your focus on building, exploring, and crafting.
Overall, the combination of instant tooltips, deep configuration, and scripting support makes this mod an essential utility. It’s lightweight, client-only, and plays nicely with almost any modded environment. Once you’ve experienced the convenience of hovering over a backpack and seeing exactly what’s inside, you’ll wonder how you ever managed without it.
