Aha but I have astigmatism.
So I really do get lens flare in real life.
It's rather annoying. Some TVs in certain lighting situations actually compound my astigmatism with the lens flare to make ultra flares.
And traffic lights at night, they're the biggest offender
A quick and dirty kind of way is to take the signal you wanna send, run it into the radar, but also run it into a decider combinator set to a number variable.
Like if I wanted to send 30 copper plates to station 4, I send it to a decider combinator that's always true, and has 2 outputs, one that outputs any, so the copper plate signal will pass through, and a second output for the number_4 signal, so number_4 and copper plates have the same value.
Then at station 4, I compare every signal to number_4, and if they're equal, I pass them through.
This has a flaw. Notably, requests with the same value. 30 iron plates to station 3 and 30 copper to station 4 will give each station iron and copper signals.
There's ways to encode a signal that avoid those problems, but this is a very simple one that'll still pull the right output all the time if you work around that limitation.
