Logic memory as a variable

The target temperature sits in the chip as a define. Whoever wants to change it has to open the code. That is too much to ask of fellow players. A logic memory (StructureLogicMemory) is a small box with exactly one value that anyone in the game can set.

One value on the network#

The logic memory has only one LogicType of its own: Setting, readable and writable. It needs no power.

lbn target MEMORY HASH("Solltemp") Setting Average

Every chip on the same data network can read it. Two heating chips in two rooms fetch the same setpoint that way. If someone changes it, both follow.

Settings for players#

In the game code there are two ways to change the value by hand:

For a setpoint in °C that is ideal: enter 21, done. The chip converts to Kelvin.

Keeping it plausible#

A fellow player can make a typo. 210 instead of 21, and your greenhouse boils. So limit every value that comes from outside:

max target target SETMIN    # never below 5 C
min target target SETMAX    # never above 35 C

If the logic memory is missing altogether, Average returns NaN. Then you take a fixed fallback value:

snan missing target
select target missing FALLBACK target
