README

🕰️ MrDayNight

by Genesis Project

Take control of Valheim’s time itself — extend the light, embrace the dark.

📜 Overview

MrDayNight is a simple yet powerful mod that lets you control the duration of day and night in Valheim.
Customize how long the sun shines or how long the shadows last — whether you want endless daylight or a world trapped in eternal night.

Perfect for both server administrators and solo adventurers, it provides fine-grained control over the day/night cycle while staying fully synced across multiplayer worlds.

⚙️ Features

✅ Customize day length and night length individually (in seconds).
✅ Fully synchronized across clients when used on a server with Jötunn.
✅ Automatically enforces server settings — players cannot override them.
✅ Works in single player (local settings) and multiplayer (server-synced).
✅ Clean logs and 100% compatible with all environment mods.

🔧 Configuration

After launching the game once, the config file will be created at:

BepInEx/config/genesisproj.mrdaynight.cfg

Example:

[Tempo]
## Duração do dia em segundos (default = 1200)
# Setting type: Single
# Default value: 1200
DayLength = 1200

## Duração da noite em segundos (default = 600)
# Setting type: Single
# Default value: 600
NightLength = 600

🧩 Dependencies

Mod	Required	Purpose
BepInExPack Valheim	✅	Core mod loader
Jötunn	✅	Syncs configurations between server and clients

🧠 How It Works

When a world starts, MrDayNight hooks into the EnvMan initialization.
The mod sets EnvMan.m_dayLengthSec based on your chosen values.
On servers, these values are propagated to all connected players automatically.
In single player, your local config values are used.

🏰 Server Behavior

Environment	Behavior
Dedicated server with Jötunn	Server config is enforced on all clients.
Single player	Local configuration applies.
Vanilla server (without Jötunn)	Each client uses local config independently.

🧑‍💻 Technical

Built using BepInEx 5.4+, HarmonyX, and Jötunn 2.26.1.
Written in C# targeting .NET Framework 4.8.
Thread-safe, no reflection abuse, and uses clean Harmony patches.

📦 Installation

Install BepInExPack for Valheim.
Install Jötunn.
