Playtime Timers (local mod)

A lightweight BepInEx plugin that adds in-game countdown timers you can start/pause anytime.

Features

• Press F8 to open/close the timer window.
• Create multiple timers with custom name + duration.
• Start, pause, reset, extend (+1m), delete.
• Timers use server/world clock when available, so they advance even if others stay on the server.
• Sleeping or other time acceleration does not speed up these timers.
• Optional auto-start for a 4-hour Royal Jelly (Infested Mine) timer when you leave an Infested Mine.
• Timer state is saved in BepInEx config and restored on next launch.

Build

From this folder:

.\build.ps1 -ValheimDir "C:\Program Files (x86)\Steam\steamapps\common\Valheim"

If your game is installed elsewhere, pass that path to -ValheimDir.

You can also configure paths in src/info:

ValheimDir=D:\Program Files (x86)\Steam\steamapps\common\Valheim
WorkDirectory=C:\Users\Martijn\AppData\Roaming\r2modmanPlus-local\Valheim\profiles\Default\BepInEx\Unknown-PlaytimeTimers.dll
BuildDirectory=C:\Users\Martijn\AppData\Roaming\r2modmanPlus-local\Valheim\profiles\Default\BepInEx\plugins\Unknown-PlaytimeTimers.dll

build.ps1 reads BuildDirectory from src/info and copies PlaytimeTimers.dll there after a successful build.

Install

The build script copies PlaytimeTimers.dll to:

• BuildDirectory\PlaytimeTimers.dll (from src/info), or
• the project root if BuildDirectory is not set.

Then launch Valheim with your normal BepInEx profile.

Notes about map/world timestamp

This version stores world-clock anchored timer state when available. If world clock API is unavailable, timers fall back to local unscaled real-time.
