HTFDayNight

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)

• Install r2modman or the

Mod Manager.

• Select How to Fish, search for HTFDayNight, click Install

(BepInEx is installed automatically as a dependency).

• Press Start modded.

Manual

• Install BepInEx 5 x64 into

the game folder - the one with How to Fish.exe

(Steam: right-click the game, Manage, Browse local files).

• Run the game once and quit, so BepInEx creates its folders.
• 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.
