Selector Combinator: Mode of Operation = Select Channel

[Christof Zedlacher]

I'm making running texts in Factorio V2 (see image) and for that purpose I could use the Selector Combinator to have an additional mode to select sorted Channels instead of sorted values:

in that mode, if I define Channels 1 .. 4 in a Constant Combinator (see image) and select Channel 2 by Selector Combinator, the Selector would output the value of the 2nd Channel (sorted by Channel name), so the output would be the value of Channel 2 = 3.
My work-around for the missing mode needs n Decider Combinators, where n is the number of Channels defined, in my case 30.

To perform the action, you need 1 selector combinator, 1 decider combinator and 1 additional constant combinator:

In the 1st constant combinator, you globally define all the signals you intend to handle. All with value 1, so a selector combinator will select by internal default order, which is well defined and stable.

This will create a unique index for every signal, if you feed this to a selector combinator.

To pick the 3rd item (that's the signal 3):

This maps index 3 to signal 3.

This ist the constant combinator with the values from where you want to pick:

Notice the signal 3 has value 4. This is what we want to pick with the given value 3 in the selector combinator.

Finally, the decider combinator that performs the miracle:

YESS - thank you!!
That's it!

Works fine with my running text
