MIMESIS - InventoryExpansion

🛟 Need help or found a bug? Get support at support.doodesch.de/inventoryexpansion.

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

Open with loot - the extra backpack slots hold real items.

Toggle with a key (default C).

Requirements

| Component | Version |

|-----------|---------|

| MIMESIS | 0.3.0 (current Steam build) |

| MelonLoader | 0.7.3+ |

Dependency: LavaGang-MelonLoader-0.7.3.

Installation

Recommended: mod manager

Install through a mod manager such as r2modman or Gale. The MelonLoader dependency and the backpack asset are handled automatically.

Manual

• Install MelonLoader 0.7.3 into MIMESIS.
• Download this package and place InventoryExpansion.dll into MIMESIS/Mods.
