Press one key to start loop, loop until you press another

[soudescolado]

Hello

I'm stuck.

I tried doing some code, but cannot see how to make it work.

What I want is what I said in the title: Start a loop when I press a key, stop it when I press another. However it seems that it queues the next key until the loop is over.

This is what I tried:

Code: Select all

lmc_device_set_name('KBD2', 'MYUSBNUMPADHERE')
lmc_print_devices()

lmc_set_handler('KBD2',function(button, direction)
  print('Callback for whole keyboard 2: button ' .. button .. ', direction '..direction)
    if (direction == 0) then
        if (button == 97) then
            for i = 100,1,-1 do
                print('a pressed')
            end
        end
        if (button == 98) then
            i = 1
        end
    end
end)

And also

Code: Select all

lmc_device_set_name('KBD2', 'MYUSBNUMPADHERE')
lmc_print_devices()
i = 0
while (i < 3) do
    lmc_set_handler('KBD2',function(button, direction)
      print('Callback for whole keyboard 2: button ' .. button .. ', direction '..direction)
        if (direction == 0) then
            if (button == 97) then
                i = 1
            end
            if (button == 98) then
                i = 0
            end
            if (button == 99) then
                i = 3
            end
        end
    end)
    if (i == 1) then
        print('LOL')
    end
end

Also, for now I am using print to test. The key I want to send is SHIFT. Not shift+something, just shift. Can that be done?

Thanks!

No, it can't be done.
Macros are enevt driven, you pres a key, lua handler is executed, once it finish, anohter macro handler can be started. It doesn't run in parallel, macros are executed one by one.
I though about introducing some timer - periodical event calls, but there was no reason so far.

Also it's currently not possible to send just shift down;.

Bummer. Oh well, thanks!

Alternatively, you can hold and fix any unused physical key so it will send press events continuously and trigger key handler. But beware some keys might not be recognized together cause of keyboard architecture. If so - try different key combinations.
edit: No, it would not work. It stops after any key pressed.
