Automation question (no dlc)

[KobaianVagabond]

short version: Is there a way to get something to ignore every other green signal?

less short version: I have my rockets built on bunker doors.  I want the doors to open and dump any debris after the rocket takes off. However, I want them to stay closed when the rocket lands. My plan now is to use the signal from the space scanneray to get e as my base signal. If there's another way to accomplish this goal, I'm open to it.

The signal counter increments up each time it receives a green signal. You can set the signal counter to output green after receiving a second green signal.

im using two ways, first is the space scanner, second is when rocket returns and loads out the collected material,

as when it start load out materials then you know that rocked is landed, or use timer

also rocket not lift up when doors is closed, but it does send out signal that it wants start or when its ready

You can add a buffer gate or a filter gate to the circuit. The gates are one-way signal, which means input will change output but output won't change input.

The signal counter did the trick but it wasn't necessary. Apparently rockets can land and take off of open bunker doors. At least now I understand how the signal counter works.

You could build a master switch using memory gate.
