HTF Day and Night

A full day and night cycle for How to Fish.

The endless noon becomes a living sky: the sun arcs overhead and sinks into the sea through a burning sunset, stars and a galaxy wheel across the night with a glowing moon, and dawn brings the sun back out of the water. Shadows, golden-hour light, moonlight, clouds, fog and even the ocean's reflections all follow the cycle - and everything returns to normal the moment you quit.

Features

• Sun that rises, crosses the sky and truly sets - with golden hour light and moving shadows on everything in the world
• Night: a painted galaxy (stars, milky band, dust rift, nebulae), a glowing detailed moon that rises as the sun sets, moon-shadows, darkened clouds
• Smooth dusk and dawn transitions - sunset burns over the sun's grave and cools on the opposite horizon
• The ocean mirrors the live sky: molten at sunset, ink at night
• Works everywhere in the world, on every island, while sailing
• Time controls: hold Right Arrow to fast-forward time, Left Arrow to rewind (configurable)
• Day length configurable (default: one full day = 20 real minutes)
• Menus stay untouched; everything restores on quit
• Co-op synced: time rides the game's own server tick - every player sees the same sky, joiners are correct instantly, zero network traffic
• Arrow keys in co-op shift only your own view; F9 resyncs you exactly
• Underwater fog is never touched - diving looks as the game intended

Installation

With a mod manager (easiest)

1. Install r2modman or the Thunderstore Mod Manager.
2. Select How to Fish, search for HTFDayNight, click Install (BepInEx is installed automatically as a dependency).
3. Press Start modded.

Manual

1. Install BepInEx 5 x64 into the game folder - the one with How to Fish.exe (Steam: right-click the game, Manage, Browse local files).
2. Run the game once and quit, so BepInEx creates its folders.
3. Copy HTFDayNight.dll and htfsky.bundle into How to Fish/BepInEx/plugins/. Both files must sit side by side.

Then just play. You spawn at noon; sunset begins after a few minutes (or hold Right Arrow to see it now). Nothing needs enabling in-game.

Configuration

After the first run, edit BepInEx/config/yoxi.htf.daynight.cfg:

Setting	Default	Meaning
MinutesPerDay	20	Real minutes per full day
TimeBackKey	LeftArrow	Hold to rewind time (None to disable)
TimeForwardKey	RightArrow	Hold to fast-forward (None to disable)
TimeScrubSeconds	8	Holding a key crosses one day in this many seconds
ResyncKey	F9	Drop your personal time shift, rejoin the shared clock
MoonlightIntensity	0.35	Strength of the moonlight at full night
MoonlightColor	#9EB3EB	Hex colour of the moonlight
FogColor	#080D1A	Night fog colour above water
FogDensityMultiplier	2.0	Night fog density as a multiple of the day's

Compatibility

• Works with the HTF custom-map loader: maps that carry their own sky automatically defer to this mod.
• Contains no game assets: the entire sky (meshes, textures, shaders) is generated content shipped in htfsky.bundle.
