AdventureBackpacks

Unofficial compatibility fork — AdventureBackpacks

This is not the official release. It is a rebuild of

Vapok's AdventureBackpacks for the Valheim 1.0

update, which moved the game to Unity 6 and broke the mod on startup.

What was broken

• ZRoutedRpc.Everybody became a const. Literal fields have no runtime storage, so the

ldsfld compiled into the bundled Vapok.Valheim.Common threw MissingFieldException.

• Inventory.AddItem gained two parameters (pickedUp, dropIfFullInv). The Harmony patch

pinned the old 8-parameter overload, so PatchAll threw out of Awake() — which meant the rest

of initialisation never ran. The flood of KeyNotFoundException: ColdResistance in the log was a

symptom of that, not a separate bug.

• Two transpilers hardcoded local variable indexes. Valheim 1.0 renumbered them: in both

Player.HaveRequirementItems and Player.ConsumeResources, V_2 is now the loop index and the

Piece.Requirement moved to V_3. The old code pushed an int where a Requirement was

expected, producing InvalidProgramException: Invalid IL code. ConsumeResources was worse: its

match pattern (Stloc_3) no longer occurred at all, so it would have silently failed to patch

and mis-counted equipped items with no error in the log.

• InventoryGrid.Element was promoted to a top-level InventoryElement, and its m_pos field

became a Position property.

• Inventory.IsTeleportable() gained a bool allowAllItems. Reading the game's IL confirms

true short-circuits to "teleportable", so false is what preserves the original behaviour.

What was changed

Source changes are limited to the above compatibility fixes; no features or balance were touched.

A netstandard reference was added because the Unity 6 assemblies target netstandard 2.1.

Vapok.Valheim.Common is consumed as a prebuilt NuGet package compiled against the old game, so it

could not be rebuilt. Its 7 stale call sites were patched at the IL level instead.

Known difference from the official build

The call to APIManager.Patcher was removed. That library is not publicly distributed and could

not be extracted from the shipped assembly. It only matters when several different mods embed the

same AdventureBackpacks.API and need to agree on a single copy — if you run other mods that consume

this mod's API, use the official release instead. The developer API zip is not shipped here for the

same reason.

Credit and support

All work belongs to Vapok. Please switch back to the official AdventureBackpacks as soon as a

Valheim 1.0 build is published, and do not report issues from this fork to the original author.

Licensed MIT, same as upstream.

Do not install this alongside the original AdventureBackpacks — both register the same BepInEx

plugin GUID.
