I meant that the impulse giver automatically starts, which you may not want for a long sequence. From what I understand from your reply you mean a delay gate, which is also a good logic gate to have, but not the thing I meant. I hope you understand what I mean. Maybe an example will make it more clear: Wait 1.1 seconds Active time 2.3 seconds delay 0.2 seconds. So at the beginning of the level, it will wait 1.1 seconds after that it will continuously go active for 2.3 seconds and delay for 0.2 seconds (like it is now). This was what I meant with the second logic gate:
The BUFFER Gate is an Automation Building that outputs Active when its input is Active, and momentarily continues to output Active when its input enters Standby. It is connected to other buildings via Automation Wire.
The amount of time the BUFFER Gate remains Active can be adjusted by the player, and can range from 0.1 - 200 seconds. When the input becomes Active again, the timer resets to the designated amount, and does not add to the current remaining time (if any). This Was copied from: https://oxygennotincluded.gamepedia.com/BUFFER_Gate they have a lot of good logic gates as well.
