Configuration

Sky Island's settings are per world, in <world>/serverconfig/inosky-server.toml, created the first time the world is loaded with the mod. A save carries its own geyser rhythm.

Edit it with the world closed

Forge rewrites a world's server config when the world unloads: a change made while the game is running is lost. To see an eruption without waiting, use /geyser now instead.

geyser

The Knock-Up Stream's rhythm. 20 ticks make a second.

Setting	Default	What it does
cycle_ticks	12000 (10 minutes)	Ticks between one eruption starting and the next.
eruption_ticks	1800 (90 seconds)	How long an eruption lasts. An eruption too short to carry somebody from the sea floor to the top is lengthened.
charge_ticks	600 (30 seconds)	The warning before an eruption: bubbles and rumbling.

return

Setting	Default	What it does
return_y	-32	Below this height in Skypiea, a body is given back to the overworld, above the same place. From -64 to 40.

angel_beach

The dials the sea leaves on the shore of the Angel Islands, and the Vision Dial's photos.

Setting	Default	What it does
dial_chance	2000	One random tick in this many, on a beach surface, lays a dial. 0 turns it off.
dial_cap	2	The most dials a stretch of beach (8 blocks around) holds at once.
vision_pictures	true	A Vision Photo shows what its taker saw: a 128×128 picture sent by the taker's game once and kept by the world, one small file a photo. false turns the pictures off, for big servers: a photo keeps the place only, and nothing is sent or kept. Photos taken before keep their picture.

For server builders

The Knock-Up Stream block

A geyser you place by hand: creative only (the Skypiea tab), no recipe, and it cannot be mined or blown up in survival. Placed on the sea floor or on dry land, it follows the geysers' rhythm, answers /geyser and /geyser now, and sends whatever stands in its column to Skypiea at its own X and Z. The arrival is yours to build there.

builders

Setting	Default	What it does
empty_skypiea	false	true gives a Skypiea with nothing in it: no cloud sea, no island, no village, no animal, and no Knock-Up Stream in the overworld. The sky and the fall back to the overworld stay. Only chunks generated after the change follow it: set it before the world is first opened (in defaultconfigs/inosky-server.toml), or with the server stopped.

Commands

Command	Permission	What it does
/geyser	operator	where the nearest geyser within 64 blocks is, what it is doing and when it erupts
/geyser now	operator	makes that geyser erupt at once
