A Create addon mod that adds cardboard backpacks fitting the Create aesthetic. Because every Create pack uses Sophisticated Storage: Backpacks, why not integrate backpacks into Create's own cardboard and package system?
Create-themed cardboard backpacks with modular upgrade system. Wearable (via Curios) and placeable as blocks, just like Sophisticated Backpacks.
No durability/fuel mechanics - those aren't fun. Once an upgrade is installed, it just works.
The backpack has upgrade slots that accept different contraption upgrades:
- Pulls nearby dropped items into the backpack (8 block radius)
- Checks every 0.5 seconds for performance
- Respects vanilla pickup delay (won't grab items you just threw)
- Disabled while sneaking
- Recipe ideas: Electron Tube + Copper?
- Voids excess items
- Recipe: Brass Tunnel (consumes glue durability) + Lava Bucket (consumes lava, returns bucket)
- Very Create-authentic - teaches players Create mechanics through the recipe
- Full 3x3 crafting grid (like a crafting table)
- Auto-crafting and compression (2x2, nugget/ingot/block conversions)
- Recipe: Mechanical Press involved?
- This is the killer feature
- Recipe: Packager + Frogport + Storage Link + Glue
- Taps into Create's logistics network
- Works with Create Storage (player's in-game name as delivery address)
- When in range of your chain transit network, the backpack's frogport retrieves packages sent via the network
- Essentially: remote base access while exploring
Note: Frogport is in base Create, not New Age (New Age is the electricity addon)
- Automatically eats food from the backpack when the player is hungry
- Configurable with whitelist/blacklist or Create-style filters
- Won't eat golden apples unless you want it to
- Automatically drinks potions from the backpack
- Configurable with whitelist/blacklist or Create-style filters
- Great for keeping fire resistance up while in the Nether
- Locks backpack slots to remember specific item types
- Only allows the memorized item in that slot (like a filter for each slot)
- Matches by item type, ignoring durability/NBT — so a half-broken pickaxe still goes in the pickaxe slot
- Useful for tool loadouts, sorted inventories, or keeping your backpack organized
- Toggle system: Enable/disable upgrades without removing them (e.g., sneak+keybind or GUI button)
- Filter support: Upgrades like feeder, drinker, and void will support Create-style filters or whitelist/blacklist configuration
Base backpack needs at least the same amount of slots as a package
- Cardboard: 1 upgrade slot
- Reinforced Cardboard: (maybe stack max increase), 2 upgrade slots
- Industrial Cardboard: (more stack max increase?) 3-4 upgrade slots
Progression through Create's material chain (basic cardboard → reinforced → brass-bound or something).
- NeoForge for Minecraft 1.21.1
- Create as dependency
- Curios API for wearable slot
- Use Create's existing items and mechanics
- Recipes should teach Create mechanics (like the void upgrade using brass tunnel + glue durability)
- Fit into Create's progression naturally
- Cardboard aesthetic matching Create's existing cardboard armor (the packages are soooooooo cute)
- Worn, taped-together boxes on the player's back
- Distinct from Sophisticated Storage's clean leather look
- Set up basic backpack item
- Implement inventory/container system
- Item persistence (DataComponents.CONTAINER)
- Make it wearable (Curios integration)
- Keybind ("B") to open from Curios slot
- Make it placeable as block
- Implement upgrade slot system (1 slot, BackpackUpgradeItem interface)
- Magnet Upgrade
- Upgrade toggle system
- Void Upgrade
- Crafting Upgrade
- Linked Upgrade
- Auto-Feeder Upgrade
- Auto-Drinker Upgrade
- Slot Memory Upgrade
- Filter/whitelist/blacklist system
- Design and implement recipes
- Textures and models
- Test with Create's logistics network
- Make a flake.nix for dev environment
Every single Create pack, even small ones, includes Sophisticated Storage just for backpacks. There's clearly demand for portable storage in Create-heavy environments. A native Create solution that:
- Fits the aesthetic
- Integrates with Create's systems (especially the linked upgrade)
- Uses Create's existing items/mechanics
- More upgrade types?
- Interaction with other Create systems (fluid storage?)
- Cosmetic upgrades (labels, paint, tape patterns)?
- Advanced logistics features building on the linked upgrade?
Keep it focused initially - get the core four upgrades working well before expanding.
