Different actions for short and hold presses of the button

Georgy · May 30, 2023

Hello!I want to turn on the fuel valve cut off in 737 pmdg with a short press of the button and turn it off by long pressing the same button.

Same with autothrottle disengage (short press) and TOGA (long press)

How to do it?

John Dowson · May 30, 2023

Take a look at the TripleUse.lua script which is included in the lua examples (zipped in your FSUIPC7 Documents folder). There is also a more advanced version of this lua script available in the User Contributions sub-forum:

You should be able to adapt either one of those for your needs.

Thank You, John! I thought maybe you did another way)
AT Disengage (67279) and TOGA (65861) I did! Thank you! Code:

joy = 3
btn = 2
interval = 100 -- 1/2 second press, gap, press limits
ignorepress = false

-- Function to time the button being pressed or left released
-- Allow only up to "interval" till decide no change
local function timebutton(test)
  while true do
		time2 = ipc.elapsedtime()
		if (time2 - time1) > interval then
			ignorepress = false
			return false
		end
	 	if ipc.testbutton(joy, btn) == test then
			time1 = time2
			return true
		end
	 	ipc.sleep(20)
	end
end

function buttonpress(j, b, du)
	if ignorepress then
		ignorepress = false
		return
	end
  
	-- Note time button was pressed
	time1 = ipc.elapsedtime()
	time2 = 0

	if timebutton(false) then
		-- First press / release counts: see if there's another
		if timebutton(true) then
			-- got another press in time, look for release
			if timebutton(false) then
				-- this was a double press, send VIEW RIGHT
				ipc.control()
                ignorepress = true --  ignore the next press we receive, i.e. the 2nd in a double-press 
			end
		else	
			-- This was a single press, send VIEW LEFT 
			ipc.control(67279)
			ignorepress = false
		end
	else
		-- This was a longer press, send VIEW FORWARD
		ipc.control(65861)
	end
end

-- Enable event on button being pressed (only)
event.button(joy, btn, 1, "buttonpress")

How do I manage the cut off valves? They work as presets. I don't know what code to enter.

Unfortunately, the github page https://github.com/joeherwig/msfs-fsuipc-lua-scripts is not working.

For presets, just use ipc.execPreset instead of ipc.control

And how I can add another controller to the same script? For example:

joy = 3
btn = 2
joy = 4
btn = 5

It will be work? Or I must to do 2 tripleuse.lua for my controllers?

Sorry, I don't understand(( Can You write example? Thank You!

No, that won't work, as you are changing the variable value. You can use one script if you know what you are doing (I am not going to explain this to you...!), but it is probably easier to use a separate script for each button.

What don't you understand? Your script contains the following lines to execute the control/event:
ipc.control(67279)
So that sends the control AUTO_THROTTLE_DISCONNECT. To send a preset instead, change that to:
ipc.execPreset("presetName")
where presetName is the name of the preset. Or add the parameter if the preset uses one, e.g. ipc.execPreset("presetName", param)

Please, check this code):

joy = 3
btn = 8
interval = 100 -- 1/2 second press, gap, press limits
ignorepress = false

-- Function to time the button being pressed or left released
-- Allow only up to "interval" till decide no change
local function timebutton(test)
  while true do
		time2 = ipc.elapsedtime()
		if (time2 - time1) > interval then
			ignorepress = false
			return false
		end
	 	if ipc.testbutton(joy, btn) == test then
			time1 = time2
			return true
		end
	 	ipc.sleep(20)
	end
end

function buttonpress(j, b, du)
	if ignorepress then
		ignorepress = false
		return
	end
  
	-- Note time button was pressed
	time1 = ipc.elapsedtime()
	time2 = 0

	if timebutton(false) then
		-- First press / release counts: see if there's another
		if timebutton(true) then
			-- got another press in time, look for release
			if timebutton(false) then
				-- this was a double press, send VIEW RIGHT
				ipc.control()
                ignorepress = true --  ignore the next press we receive, i.e. the 2nd in a double-press 
			end
		else	
			-- This was a single press, send VIEW LEFT 
			ipc.execPreset("PMDG_B737-7_FUEL_CUT_OFF_LEVER1_UP")
			ignorepress = false
		end
	else
		-- This was a longer press, send VIEW FORWARD
		ipc.execPreset("PMDG_B737-7_FUEL_CUT_OFF_LEVER1_DN")
	end
end

-- Enable event on button being pressed (only)
event.button(joy, btn, 1, "buttonpress")

Can you not do this yourself? Why don't you just try running it, and use the provided debugging facilities if you have any issues.

As you are not using the double press, then you should at least remove the following line (as it will create an error if you do double-press):
ipc.control()

Or, better still, remove the code that handles a double-press completely if not using this.

Вы не можете сделать это сами? Почему бы вам просто не попробовать запустить его и использовать предоставленные средства отладки, если у вас возникнут какие-либо проблемы.

I meant, did I enter the action correctly in brackets and quotes? Shouldn't there be numbers?

Why? The preset is a name, and the documentation for this function is:

Quote

ipc.execPreset(“presetName”, param)[Not WideClient]
This executes the calculator code associated to the argument presetName using the WAPI execute_calculator_code method. Note that the preset name must be given as it appears in the events.txt or myevents.txt file, not as appears un the drop-down menus where underscores are replaced by spaces.

N.B. To use this function, the FSUIPC WASM module must be installed, and the WASM interface active in FSUIPC7.

The only number needed is the parameter, if the preset uses one (most don't).

Thank You!

Tell me please how to implement such a function: I raise the chassis crane in 737 (Thrustmaster Boeing), the lever presses the button all the time. After 10 seconds, the second action is activated: the lever itself is transferred to the off position. Sorry for my bad English)

Sorry but I don't understand. What is a 'chassis crane'? What do you want to do?

I'm sorry... I used a translator

I would like to do this:

1. In a Boeing 737, I do gear up.

2. Wheels retract

3. After 10 seconds, the gear lever automatically switches to off mode.

Georgy · May 30, 2023

B=TCA YOKE BOEING
B.GUID={E05CFE20-D530-11EC-8003-444553540000}

Can I use letter "B" at "joy' line of Tripleuse.lua? Or only number?

John Dowson · May 31, 2023

No, you should use the number.

I was able to do it.
Assigned "gear up" to physical lever without lua script.
In tripleuse.lua assigned only one action (hold press): move virtual lever to position "gear off" after 10 seconds when the physical lever is up.

I'm sorry. Can You help me? I don't know which lines I can delete, if i need one action (hold press), or 2 actions (hold press and single press) only.

Thank You.) The letter would be more convenient when changing different joysticks, because it is attached to each device, even when it is disabled.
