ExpandedPlayerInventory

A standalone Valheim BepInEx mod that expands player inventory rows (up to 50 rows, default 20) with a built-in scrollbar and mouse-wheel scrolling support.

Known Issues & Workaround

[!NOTE] Occasional Blank Grid on Initial Open:

• Symptom: In certain environments or heavy modded setups, opening the inventory for the very first time after joining a world, respawning, or loading into a new area may occasionally display only the wooden background panel without the item slots rendering immediately.
• Quick Solution: Simply close (Tab or Esc) and reopen the inventory once. This forces the UI layout to synchronize, after which all item slots, graphics, and scrolling will render smoothly and normally for the remainder of your session.

Features

• Configurable player inventory rows (4 to 50 rows).
• Integrated Valheim-themed scrollbar.
• Mouse scroll wheel and Gamepad navigation support.
• Fully standalone: can be used with or without ValheimPlus.

Configuration

Configuration file is generated at BepInEx/config/ckforgame.ExpandedPlayerInventory.cfg after first launch:

• playerInventoryRows: Number of player inventory rows (min 4, max 50, default 20).
• scrollSensitivity: Mouse wheel scroll sensitivity (min 50, max 1500, default 350). Higher values scroll faster with less wheel movement.
• rememberScrollPosition: Remember the last scroll position when opening the inventory, instead of always jumping back to the top (default true).

Compatibility with ValheimPlus

[!IMPORTANT] If you are using ValheimPlus, please ensure inventoryRows in your ValheimPlus configuration (valheim_plus.cfg) is set to 4 (the vanilla default) or leave the [Player] inventory expansion disabled.

Letting ValheimPlus expand inventory rows simultaneously will conflict with this mod's scrollbar positioning and grid layout management. Use ExpandedPlayerInventory's configuration to specify your desired rows instead.

Changelog

• v1.2.0:
  • Feature: Added Scroll Position Memory (rememberScrollPosition, default true), keeping your scroll view intact across inventory toggles and chest looting.
  • Feature: Dynamic Resolution & UI Scale adaptation (automatically recalculates layouts upon settings changes without game restarts).
  • Reliability: Added item safety defense-in-depth net in Humanoid.DropInvalidItems and Player.SetInventorySize to strictly prevent item dropping or loss.
  • Reliability: Enhanced scrollbar template search with programmatic UI fallback.
  • Reliability: Thorough session state reset on logout and world join.
• v1.1.0:
  • Feature: Added configurable mouse wheel scrollSensitivity (default 350, range 50–1500) for ~5x faster, effortless scrolling.
  • Feature: Standardized plugin GUID and configuration filename to ckforgame.ExpandedPlayerInventory.cfg (with automatic migration from legacy config).
  • Fix: Resolved ValheimPlus mod conflict where container resizing caused negative viewport heights and culled item slots on first open.
  • Fix: Fixed repeated 20-row pop-in / flashing by restricting opening synchronization strictly to the first open of each world session.
  • Fix: Added runtime layout failsafes in InventoryGui.Update preventing item graphics from ever being culled while the canvas settles.
• v1.0.4: Deferred clipping to after Animator transition; fixed compatibility with ValheimPlus and other inventory mods.
• v1.0.3: Added known issues and temporary workaround documentation; improved canvas and clipping update handling during inventory opening animation.
• v1.0.2: Fixed first-time inventory open render bug where slots were displaced off-screen and invisible until reopened.
• v1.0.1: Initial release with standalone scrolling inventory and ValheimPlus compatibility guidance.
