The battery charger

Battery cells for tools and wall lights end up in the battery charger. The large charger (StructureBatteryCharger) has 5 slots, the small one (StructureBatteryChargerSmall) 2. Which battery is full, which still needs time? The chip tells you before you walk over.

What a battery in a slot reports#

ChargeRatio is the value you work with: 0.5 means half full, 1 means full. For percent multiply by 100.

lbs ratio CHARGER 0 ChargeRatio Average  # slot 0
mul percent ratio 100

With one charger on the network Average returns exactly its value – and NaN if the charger is missing. You already know the NaN guard for that.

“All full” across all slots#

A slot is fine if it is empty or its battery is full. All slots together are fine if every single one is fine. That is an and across the loop:

move allFull 1
move i 0
slot:
lbs present CHARGER i Occupied Average
lbs ratio CHARGER i ChargeRatio Average
sge ok ratio FULL       # full?
seqz empty present      # or empty?
or ok ok empty
and allFull allFull ok
add i i 1
blt i SLOTS slot

Use 0.99 as the limit instead of exactly 1. Whether the value reaches exactly 1 in the game depends on the calculation behind it. A threshold keeps you on the safe side.

An empty charger is not “full”#

If no battery is inside at all, every slot is “fine” and the lamp would report “full”. Count the batteries as well and require at least one:

add count count present   # inside the loop
sgtz present count        # after the loop
and allFull allFull present

If the charger is missing entirely, count becomes NaN. sgtz then returns 0 and the lamp stays off. For the display you replace NaN with 0 using snan and select.
