Split Scroll Mod

Scroll your mouse wheel to adjust the amount when splitting item stacks — no more clicking and dragging the slider one item at a time.

Features

• Scroll up/down with the split-stack slider open to increase/decrease the amount
• Modify the amount by holding CTRL or SHIFT
• Works anywhere the vanilla split dialog appears
• Lightweight — no impact on performance or other systems

Installation

1. Install BepInExPack Valheim if you haven't already (handled automatically if installing via a mod manager)
2. Install this mod through r2modman, Thunderstore Mod Manager or manually drop the DLL into BepInEx/plugins/

Usage

1. Open your inventory
2. Split a stack as normal (Shift+click)
3. With the split dialog open, scroll your mouse wheel to adjust the amount by 1 per notch
4. Hold CTRL to adjust by 10 per notch or hold SHIFT to adjust by 5 per notch
5. After first launch, edit the config file in BepInEx\config\com.celticslayer.splitscroll.cfg for custom scroll amounts.

Compatibility

• Client-side only — does not affect server state or require other players to have it installed
• Should be compatible with other inventory/UI mods, since it only modifies the local split dialog's slider value
