How to Forward Signals of True OR Conditions?

[HelloWorld]

Hi

Is there any way to forward the signals of "true" OR conditions?

I wish to display which items are out of stock using a single decider combinator with multiple conditions.

Please see the attached image for clarification.

Thanks in advance.

This was easy to do even with old combinators, but requires the use of negative numbers and a constant combinator as well.

Set the decider with a single condition, "Each < 0", and a single output, "Each=1". Then on the input, wire your inventory contents and also a constant combinator with -1 of each item you want restocked. You can have it restock at higher levels with bigger negative numbers (like ammo=-100 to restock when 99 or fewer are left).

Thank you!
I will try this.
