🎒 InventoryPLUS

Version 1.0.0

Meant to be more of a vanilla-like mod to allow you to upgrade your inventory. It IS still a WORK IN PROGRESS. I just need testers!

With this mod you get 1 EXTRA item slot by default.

Even more if you get both fanny pack and back pack upgrades! Backpack and Fannypack are weightless. Utility packs still have their weight!

4 slots to start > add backpack to get 4 more for a total of 8, then fanny pack for a total of 10.

You can put on a fanny pack on without having the backpack first for a total of 6 slots.

Slots are added to main inventory hud which allows you to avoid opening your packs to select items and use, drop or throw them.

You can also wear 1 jetpack or 1 rocketpack while wearing both backpack and fannypack to have 3 packs on at once!

Back/Fanny packs do not appear on the player visually and cannot be seen or opened by other players.

They can however see your jet/rocket pack!

Swap through packs with "B" or whatever you configure it too!

• Future plans to make compatible with PEAK Packs to show all packs later once I get that mod to act right!

✨ FEATURES

• 🧳 4 base pockets — vanilla 1–3 stay; the old backpack widget is pocket 4
• 🎒 Backpack +4 — extras on keys 5–8
• 👝 Fanny pack +2 — extras on keys 9–0
• 🔟 Keys 1–0 left to right. Rebind vanilla Item Slot 1–3 / Backpack Slot for 1–4; 5–0 are this mod’s number keys
• 📦 Worn pack icons above the bar (not extra pockets)
• 🎮 B cycles worn packs into your hands, then wraps back to start (worn again)
• 📥 Tab stashes a held pack back on
• 🔥 Fuel / use bars still show (lanterns, scout cookies, jetpack fuel, rocket fuse)
• ⚖️ Backpack / fanny self-weight is not added (upgrade only). Jet / rocket still weigh. Loot in extra slots still weighs
• 😵 Pass-out drops extras and worn packs so death does not delete them

🎮 How It Works

1. Pockets — you always have 1–4. Wear a backpack for 5–8. Wear a fanny pack for 9–0
2. Pick up a pack — it equips to its wear slot (back / hip / flight), not into a pocket
3. B — cycle backpack → fanny → jet/rocket into your hands. Press through the list to put the last one back on
4. Tab — put the held pack back on without cycling
5. Drop — throw the selected / held pack. Extra slots from that backpack or fanny hide until it is worn again
6. Jetpack in hands — you cannot fly until it is worn again
7. Rocket pack — light the fuse, then wear it. Remaining fuse is kept. After launch the rocket is consumed and removed for everyone

🌐 Multiplayer

• ✅ Everyone should have InventoryPLUS — extra slots and extra worn packs are synced
• 🔁 Extra worn-pack data uses Photon RaiseEvent 166 (magic tony4twentys.InventoryPLUS)
• 👀 Other players see the pack in the vanilla wear slot. Showing all worn packs on other scouts is PEAK Packs territory, not this mod (which it still needs fixed and made compatible)

🤝 Notes / other mods

• B is this mod’s pack-cycle key. PEAK Packs also uses B to open a pack — pick one bind setup if you run both
• Pairs naturally with Start With Backpacks

📦 Installation

1. Download via Thunderstore
2. Place tony4twentys-InventoryPLUS.dll in /PEAK/BepInEx/plugins/
3. Launch. Wear a backpack or fanny pack to grow the bar

🔥 Or use a mod manager 🔥

Changelog

[1.0.0] - 2026-09-18

Initial release. Vanilla-like inventory upgrade: more pockets when you wear packs, plus dedicated wear for backpack, fanny pack, and flight packs.

Hotbar

• 4 base pockets. Vanilla slots 1–3 stay, and the old backpack widget becomes pocket 4
• Backpack worn: +4 extras (slots 5–8)
• Fanny pack worn: +2 extras (slots 9–0)
• Max 10 pockets. Bar expands left so the right edge stays put
• Keys 1–0 left to right. Vanilla rebinds cover 1–4; 5–0 use this mod’s digit keys
• Item names and fuel / use bars show on extra slots (lanterns, cookies, jetpack fuel, etc.)

Worn packs

• Backpack, fanny pack, and jetpack / rocket pack can be worn together. Packs sit as icons above the bar, not as pockets
• B cycles worn packs into your hands, then wraps back to worn (nothing in hands)
• Tab (stash / unselect) puts the held pack back on
• Drop throws the selected / held pack
• Extra slots from a backpack or fanny hide while that pack is in your hands, then come back when it is worn again
• Jetpack cannot fly while it is in your hands
• Light a rocket pack, then wear it — the fuse keeps its remaining time and can still launch you
• A spent rocket pack is consumed and removed from inventory (synced), same idea as vanilla use-up

Weight, pass-out, sync

• Equipping a backpack or fanny pack does not add that pack’s own carry weight (it is an inventory upgrade). Jetpack / rocket pack still add pack weight. Items inside extra slots still weigh
• Pass-out / death drops extra-slot items and worn packs to the ground (staggered pack drops) so they are not erased
• Everyone in the lobby needs the mod. Extra worn packs sync with Photon RaiseEvent 166 (tony4twentys.InventoryPLUS)

Config

• BepInEx config tony4twentys.InventoryPLUS.cfg: Slot5–Slot0 (defaults 5–9 and 0) and PackCycle (default B)
• Slots 1–4 use vanilla Item Slot 1–3 / Backpack Slot rebinds
