I've noticed that some crafts on this website have doors controlled by vizzy. When you click on the MFD, the pistons controlling the door retract without the need for an AG. I suck at vizzy and haven't figured out how to reverse-engineer them. Could someone please tell me how they work?
Inputs,
Change the mfd’s name and note down a variable you want to use.
Set the input on the part to be “mfdname.FlightProgram.variablename”
