Finding prefabs

In the game the thing is called “Lever” – and in code StructureLogicSwitch. Guessing prefab names often goes wrong. And a wrong name gives no error message: HASH("StructureLever") is a valid number, there is just no device that belongs to it.

Display name and prefab name#

You find the names in the prefab search of the IC10 coder: type the English or German name, read off prefab and hash.

The game's typos#

Some prefabs are misspelt in the game itself. You have to copy them exactly like that:

Upper and lower case count as well: HASH("structuregassensor") is an entirely different number.

Looking it up in the game#

Every device with logic reports its own hash in the LogicType PrefabHash. Attach an unknown device to a pin and the housing shows you the number:

l r0 d0 PrefabHash
s db Setting r0      # hash of the device on d0

You compare the number with the prefab search – or store it directly as a define.

Storing the hash as a define#

Two notations, same result:

define SENSOR HASH("StructureGasSensor")   # Gas Sensor
define SENSOR2 -1252983604                 # Gas Sensor

The chip computes HASH("…") on load, you never need to know the number. For the character limit, though, the written long form counts: the number is shorter, the name more readable. In the workshop style either one is used – the name inside HASH or the number – always with the English device name in the comment.
