EasyBackpack (Compatibility Fix) — 1.1.7

This is a community-maintained compatibility fix for the original EasyBackpack mod.

Original author: nickklmao Original Thunderstore page: https://thunderstore.io/c/peak/p/nickklmao/EasyBackpack/

What is this?

Are you tired of having to drop your backpack to access it? No need to worry, you don't have to anymore! Using a custom keybind (see below) you can access your backpack without having to drop it.

This package is a fork of the original EasyBackpack, fixed for the PEAK game update of 2026-08-12 which broke the original 1.1.2 build. It is not an official update by the original author.

What was fixed?

No gameplay logic was changed.

Manual Installation

1. Install BepInEx from here.
2. Drop EasyBackpack.dll into <game directory>\BepInEx\plugins.
3. Remove any previous copy of the original EasyBackpack.dll first (same plugin GUID — keeping both installed will conflict).

Configuration

Config file: <game directory>\BepInEx\config\nickklmao.EasyBackpack.cfg

• Backpack Key (default B) — the key to open your backpack while it's on your back.
• Alternative Backpack Key (default None) — an optional second key.

License

The original package ships without a license file. This fix is provided in good faith for the community; all credit goes to the original author.

Changelog

1.1.7 (compatibility fix, community-maintained)

Jetpack refuel compensation rewritten — no more fuel flicker, no fuel duplication, works on slow connections.

Fixed:

• Refuel compensation now restores the actual pre-rollback fuel value instead of a computed target. Fuel spent while flying during the refuel window is no longer refunded (no fuel duplication, nothing leaks to the host).
• Back-to-back refuels (two or more within a short window) no longer show a visible drop-then-jump: each rollback sync is matched against the current refuel base and restored in the same frame.
• No more fixed 1.5s timeout: the pending refuel state now lives for 30s, so a rollback arriving late (slow / high-latency connections) is still compensated instead of silently dropping the fuel.

Unchanged:

• All gameplay logic, config keys, and plugin GUID (nickklmao.easybackpack) are otherwise identical to 1.1.6.

1.1.6 (compatibility fix, community-maintained)

Jetpack refuel fixes for non-host clients.

Fixed:

• Jetpack self-refuel rollback: when a non-host client refuels their own equipped Jetpack, the game's AddFuelToJetpack triggers an EmptySlot() → host SyncInventoryRPC that carries the pre-refuel fuel value and overwrites the client's local fuel. The fix compensates the local Fuel / UseRemainingPercentage back to the authoritative value after the stale sync lands — no extra RPC is broadcast, so the host copy is never double-counted.
• Jetpack fuel amount now matches ground refuels: refuelling a back-mounted Jetpack always added a fixed 50, while ground refuels compute from the held item. Back refuels now use the same per-item fuel calculation as ground refuels.
• Robustness: the forced-interact patch state machine is reset on every Prefix (no stale input restore), all wheel-close paths clear both access flags, and the slot-count / GetFromEquippedBackpack fallbacks log a throttled warning instead of silently swallowing exceptions.

Unchanged:

• All gameplay logic, config keys, and plugin GUID (nickklmao.easybackpack) are otherwise identical to 1.1.5.

1.1.5 (compatibility fix, community-maintained)

Per-backpack-type slot count + Rocketpack handling.

Fixed:

• The backpack wheel now uses the equipped item's real capacity instead of the hardcoded 4-slot value. slotCount is read from CharacterBackpackHandler.activeBackpackVisuals.slotCount (the prefab-configured value the game itself uses in BackpackOnBackVisuals.Interact_CastFinished):
  • Backpack → 4 slots (unchanged)
  • Fannypack → 2 slots (previously the wheel showed 4, letting you stash items into slots 3/4 that could never be retrieved)
• Rocketpack no longer opens the backpack wheel at all. The game's official interaction for a Rocketpack on the back is firing it (LightRocket), not opening the inventory; the quick-access key now does nothing instead of opening a wheel that would swallow items into unreachable slots.
• Falls back to 4 slots (inside try/catch) if the active visuals are unavailable.

Unchanged:

• All gameplay logic, config keys, and plugin GUID (nickklmao.easybackpack) are otherwise identical to 1.1.3.

1.1.4

• Fix README.md

1.1.3 (compatibility fix, community-maintained)

Restores the original EasyBackpack 1.1.2 for the PEAK game update of 2026-08-12.

Fixed:

• BackpackSlot.hasBackpack field was removed by the game update; both references now use BackpackSlot.IsEmpty() (backpackType == BackpackType.None).
• GUIManager.OpenBackpackWheel signature changed from (BackpackReference) to (BackpackReference, int slotCount, BackpackSlot.BackpackType); both call sites now pass the equipped slot's itemSlots.Length and backpackType.
• The game's BackpackWheel.Update reordered its close checks (the !interactIsPressed close now runs after the backpack.exists check), which silently broke the original MonoMod IL hook (wheel closed immediately after opening). Replaced the IL hook with a Harmony Prefix/Postfix that holds interactIsPressed while the backpack key is pressed, preserving the original "hold key to keep the wheel open" behavior.

Unchanged:

• All gameplay logic, config keys, and plugin GUID (nickklmao.easybackpack) are identical to the original 1.1.2.
