Adds extra backpack inventory slots you toggle on demand with a configurable key, shown in a custom animated panel that slides in and out. Carry more loot without permanently cluttering the standard 4-slot hotbar. Standalone, no MimicAPI required.
Features
- Adds 4, 9, or 16 extra inventory slots laid out as a square grid (2x2, 3x3, or 4x4); the count is configurable. The new slots are real, usable inventory, not just a visual overlay.
- Toggle between the standard hotbar and the backpack with a configurable key (default
C); the mod reads the key live each frame. - Extra slots render in a custom backpack UI panel that uses the bundled sprite and slides in and out with a short eased animation. If the image is missing it falls back to a translucent black panel.
- Shows a visual key hint on the panel displaying the currently configured toggle key.
- Context-aware slot scrolling: while the backpack is open, slot cycling affects only the backpack slots; while it is closed, it affects only the standard 4 slots.
- Cursor handoff on toggle: opening the backpack moves your selection to the first backpack slot, and closing it returns the selection to the standard inventory, so the cursor never stays stuck on a hidden slot. Each direction is configurable.
- Optional backpack-first pickup: while the backpack is open, items you pick up fill the backpack slots before the standard inventory (host / single-player only).
- Optional movement-speed reduction to 50% while the backpack is fully open, restored automatically when it closes.
- Automatically hides the panel during loading screens and map changes, and when you leave the game or return to the title screen.
Screenshots

Usage
- Press the configured toggle key (default
C) to slide the backpack panel in and out. The panel sits at the bottom-right of the screen and shows a key hint. - When the backpack is open, slot scrolling and selection cycle only the backpack slots; when it is closed, they cycle only the standard 4 hotbar slots.
- Opening the backpack jumps your selection to the first backpack slot; closing it returns the selection to your previous standard slot, so the cursor is never stuck on a hidden slot (toggle each via
SelectBackpackSlotOnOpen/RestoreStandardSlotOnClose). - With
FillBackpackFirston, items you pick up while the backpack is open go into backpack slots first. This changes server-side placement, so it only applies when you host or play single-player. - With
ReduceMovementSpeedon, you move at 50% speed while the backpack is fully open, and full speed is restored when it closes. - The panel auto-hides during loading screens and map changes, and when you leave the game or return to the title screen.
