Buildings, recipes and bot commands

Everything in the game in one place, taken straight from the game's own data (version 0.9.3.9).

Buildings

Building	What it does	Cost	From level
Belt	Moves items forward. Drag to lay a line. A belt takes one input: from behind, or from one side when nothing feeds it from behind; a Merger joins lines.	free	1
Extractor	Place on a deposit. Mines it forever and outputs forward, one item at a time. To feed two machines from one extractor, split its belt with a Splitter (level 4).	5 Wood and 5 Stone	1
Sign	A label for your factory. Click it to edit the text.	free	1
Furnace	Smelts ore into plates, stone into brick, iron plates into steel and sand into glass. Picks the recipe from its input.	10 Stone	2
Sawmill	Cuts 2 wood into 1 plank.	10 Wood	2
Assembler	Crafts parts from several inputs. Click it to choose a recipe.	10 Iron Plates and 5 Planks	3
Trash	Destroys anything fed into it, from any side.	5 Stone	3
Splitter	Takes items from behind and deals them out front, left and right.	4 Iron Plates	4
Merger	Combines items from the back, left and right into one output, taking turns fairly.	4 Iron Plates	4
Tunnel	Carries items underground. Place an entrance, then an exit up to 4 tiles ahead facing the same way.	4 Iron Plates and 2 Planks	4
Filter	The chosen item passes straight through; everything else leaves by the sides.	4 Iron Plates and 4 Wire	5
Depot	Stores up to 200 items. Belts and bots can fill it; it unloads onto a belt at its front.	10 Iron Plates and 10 Bricks	5
Hub Extension	Part of the Hub. Place it touching the Hub or another connected extension: anything belted in, from any side, is delivered.	10 Bricks and 5 Iron Plates	5
Fabricator	Builds advanced components from three inputs. Click it to choose a recipe.	10 Steel, 20 Bricks and 5 Circuits	6
Bot Bay	Home of one programmable bot. Click the bay to write its program.	10 Steel, 10 Circuits and 10 Gears	6
Priority Splitter	Sends items straight ahead while it can. Only when the front is blocked do they go out the sides: an overflow valve.	6 Iron Plates and 2 Wire	7
Trading Post	Sells anything fed into it, from any side. Pays more the further it is from the Hub: ×1 nearby, up to ×2 at 80 tiles. Sales here don't count toward level goals.	20 Bricks, 5 Steel and 10 Planks	8

"Per minute" is what one machine makes when it is never short of input. Need more? Build more machines side by side, or use the planner in the game's Recipe book.

Bot commands

From level 6 a Bot Bay holds one bot you program with one command per line. Bots fly over everything, so they can stock machines, empty depots and run outposts.

Command	What it does
`goto x y`	fly to a tile (bots fly over everything)
`goto hub / goto home`	fly to the hub, or back to this bay
`goto nearest depot`	fly to the closest building of a type (depot, assembler, furnace, extractor, …)
`fill item\|any`	keep taking from the building below until the bot is full
`empty [item\|all]`	keep dropping into the building below until the bot is empty
`set name 0 / add name 1`	store a number in a variable (add can be negative)
`if name >= 10 jump label`	check a variable
`take item [n]`	pick up from the building below: hub, depot, a machine's output, an extractor
`take any [n]`	pick up whatever is there
`take wire 4 / take gear 2`	several takes in a row carry a mix; the cargo limit counts every kind together. The panel shows what the bot holds and why a line did nothing
`drop [item\|all] [n]`	put cargo into the building below: hub, depot, a machine's input, trash
`wait seconds`	pause
`name:`	a label to jump to
`jump name`	continue from a label
`if carrying < 5 jump name`	jump when the cargo count matches (< > <= >= = !=)
`if hub item > 50 jump name`	check hub storage
`if here item = 0 jump name`	check the building below (use any for all items)
`stop`	end the program

Example programs (the same ones the Bot Bay offers)

Stock a machine

# Keep a machine stocked from the hub.
# Change 5 3 to your machine's tile (hover it to see x y).
goto hub
take iron_plate 20
goto 5 3
drop all
wait 5

Outpost ferry

# Bring everything from a remote depot back to the hub.
# Change 40 12 to your depot's tile.
start:
goto 40 12
take any
if carrying = 0 jump idle
goto hub
drop all
jump start
idle:
wait 5
jump start

Nearest depot run

# Fill up at the closest depot, unload at the hub, count the trips.
set trips 0
start:
goto nearest depot
fill any
goto hub
empty
add trips 1
if trips < 100 jump start
stop

Collect output

# Collect finished parts from a machine and deliver them.
# Change 8 2 to your machine's tile.
start:
goto 8 2
take any
if carrying < 10 jump start
goto hub
drop all
