FlyWithLua / FlyWithLua script example

Last post by dmahr - December 02, 2021, 04:43:46 PM

FlyWithLua is an X-Plane plugin which gives KBD03 boards access to datarefs and commands by simple (or complex) LUA scripts.

Information and download (login required) can be found here:

Let us try to link a mechanical encoder to the OBS1 (omni bearing selector) of the CDI instrument #1.
Our encoder is connected to a KBD03 board and sends 'a' keystrokes when turned left and 's' when turned right.

A typical FlyWithLua script would look like this:

First define a variable we want to connect with the dataref associated with the OBS setting:

dataref("OBS1", "sim/cockpit2/radios/actuators/nav1_obs_deg_mag_pilot", "writable")

Next we fetch the keystrokes of the KBD03:

if KEY_ACTION == "pressed" then
...

Then we can ask for a specific key (key 'a' in this case):

if KEY_ACTION == "pressed" then
if (VKEY == 65) then -- 'a' key
...

Now we define the action for clockwise rotation:

if KEY_ACTION == "pressed" then
if (VKEY == 65) then -- 'a' key
OBS1 = OBS1 + 1 -- increment OBS1
...

And now for counterclockwise direction:

if KEY_ACTION == "pressed" then
if (VKEY == 65) then -- 'a' key
OBS1 = OBS1 + 1 -- increment OBS1
elseif (VKEY == 83) then -- 's' key
OBS1 = OBS1 - 1 -- decrement OBS1
end
end

Let us also use the double encoder feature of the KBD03 with 'ctl+a' and 'ctl+s' for the second encoder.
When the pushbutton is pressed we dial the OBS fast then and when we press again we dial slow again.
Thus we modify the code:

if KEY_ACTION == "pressed" then
if (VKEY == 65) then -- 'a' key
if CONTROL_KEY then -- Ctrl pressed
OBS1 = OBS1 + 3 -- increment OBS1 by 3
else
OBS1 = OBS1 + 1 -- increment OBS1 by 1
end
elseif (VKEY == 83) then -- 's' key
if CONTROL_KEY then -- Ctrl pressed
OBS1 = OBS1 - 3 -- decrement OBS1 by 3
else
OBS1 = OBS1 - 1 -- decrement OBS1 by 1
end
end
end

if KEY_ACTION == "pressed" then
if (VKEY == 65) then -- 'a' key
OBS1 = OBS1 + 1 -- increment OBS1
...

And now for counterclockwise direction:

if KEY_ACTION == "pressed" then
if (VKEY == 65) then -- 'a' key
OBS1 = OBS1 + 1 -- increment OBS1
elseif (VKEY == 83) then -- 's' key
OBS1 = OBS1 - 1 -- decrement OBS1
end
end

Let us also use the double encoder feature of the KBD03 with 'ctl+a' and 'ctl+s' for the second encoder.
When the pushbutton is pressed we dial the OBS fast then and when we press again we dial slow again.
Thus we modify the code:

if KEY_ACTION == "pressed" then
if (VKEY == 65) then -- 'a' key
if CONTROL_KEY then -- Ctrl pressed
OBS1 = OBS1 + 3 -- increment OBS1 by 3
else
OBS1 = OBS1 + 1 -- increment OBS1 by 1
end
elseif (VKEY == 83) then -- 's' key
if CONTROL_KEY then -- Ctrl pressed
OBS1 = OBS1 - 3 -- decrement OBS1 by 3
else
OBS1 = OBS1 - 1 -- decrement OBS1 by 1
end
end
end

Finally we wrap the code into a function which is called whenever a keystroke from the KBD03 is received.

function kbd03_event_handler()
if KEY_ACTION == "pressed" then
if (VKEY == 65) then -- 'a' key
if CONTROL_KEY then -- Ctrl pressed
OBS1 = OBS1 + 3 -- increment OBS1 by 3
else
OBS1 = OBS1 + 1 -- increment OBS1 by 1
end
elseif (VKEY == 83) then -- 's' key
if CONTROL_KEY then -- Ctrl pressed
OBS1 = OBS1 - 3 -- decrement OBS1 by 3
else
OBS1 = OBS1 - 1 -- decrement OBS1 by 1
end
end
end
end

do_on_keystroke("kbd03_event_handler()")
