How to detect switch position in cockpit?

[Mt5_Roie]

So I have the following in clickable data:

 

elements["PTR-BATTERY-PWR"]        = {class = {class_type.TUMB,class_type.TUMB}, hint  = _("Battery Power"), device = devices.AVIONICS, action = {device_commands.Button_20, device_commands.Button_21}, arg = {246,246}, arg_value = {-1,1}, arg_lim = {{0,1},{0,1}},updatable = true}

 

I got it by looking at the code from the A-10C. From this code I have button 20 coded to start the power up for the plane, button 21 does the opposite. The problem is that if someone clicks on the switch when it's in the on position using left click - it activates buttons 20 and not 21. If they right click it activates button 21. So I'm trying to make sure that when the switch is in the on positon - power is on, and if its in the off - power is off.

 

So is there a programmatic method of detecting switch state? In this case I'd like to know if PTR-BATTERY-PWR is in 0 or 1 state. Based on that I can program the appropriate code.

 

on a side note, is there a way to force it so the button can't be put down unless it's done via right click? So left click for one way and force right click to turn off?

Value.

 

function SetCommand(command,value)
if command == 3072 and BattAvail:get() == 1 then
	if value == 1 and APU_N1:get() == 0.0 then
		APU_Start()
	end
               
               if value == 0 yadda yadda
end

 

Note that SetCommand is passed a command and a value. Do some looking into what value your switches send you.

Will test tonight sometime. Thanks again as usual.

 

Quick follow up question - how do set the aircraft to start up with no power on? Seems like everytime I get in the cockpit the hud and electric are already on. Is there a varible in the main LUA to turn everything off to begin with?

You create the concept of electrical power yourself.

Should have known there wasn't going to be an easy answer. I''ll start working on a electrical system this week.
