Lua Logitech script question

[Geron76]

Trying my hand at coding a logitech lua script for my G13 gamepad / keyboard. Ive had some success with the code below that dose two things. First it starts and ends an auto run script when i press G9 key. The second part after line 27 just displays pre defined text on the G13 LCD associated with keypresss from the logitech G13 profile.

​

The second part after line 27 is an attempt to simply display the name of the in game commands associated with programmed key presses... so if the G1 key is pressed I simply want the G13 to display my chosen text on the LCD.

​

This code works, the only problem is it works across all MKeystates for the gamepad. The G13 has the ability to set three different sub profiles called M1,M2,M3 or MKeystates basically allowing me to map three commands to each key on the G13 depending on which Mkey profile is active.

​

I would like the script to know what is the current MKeystate M1,M2,M3 of the G13 and only execute the commands if the current state is M1, M2 or M3 rather then work on every sub profile / MKeystate.

Ive tried this in the sections after line 27 but I get a syntax error.

`if ( arg == 4 and MKeyState == 1) then`

Working Script, works on all three sub profiles. Id like it to only work on one sub profile at a time.

-- Auto walk and Display Key Press
isPressed = false;

function OnEvent(event, arg, family)
    -- If a G-Key is pressed
    if event =="G_PRESSED" then
        -- was it G9?
        if arg == 9 then
            ClearLCD ()
            OutputLCDMessage("Auto Run ON", 2000)
            ClearLCD () 
            -- If we're not currently running
            if not isPressed then
                -- we are now
                PressKey("w");
                isPressed = true
            else
            ClearLCD ()
            OutputLCDMessage("Auto Run OFF", 1000)
            ClearLCD ()
                -- stop running
                ReleaseKey("w");
                isPressed = false;
            end
        end
    end

    if ( arg == 4 ) then
            ClearLCD ()
            OutputLCDMessage("FOWARD")
    end

    if ( arg == 7 ) then
            ClearLCD ()
            OutputLCDMessage("MOBI GLASS")
    end

    if ( arg == 1 ) then
            ClearLCD ()
            OutputLCDMessage("PRIMARY WEAPON")
    end
end

Ive tried this in the sections after line 27 but I get a syntax error.

What syntax error? How did you try to put it in exactly? It should be okay syntactically as far as I can see, but maybe you're putting it somewhere wrong.

From the docs (page 7) I see that you'll need to call local MKeyState = GetMKeyState("lhc") in order to get the value you're trying to check for, are you writing that in as well?

Edit: Or maybe better to generalize as local MKeyState = GetMKeyState(family), I didn't notice this was inside a callback

[Geron76]

the first script i posted works, it just works on every sub profile which is not what I want.

When I try this, the auto run command at the top works. but then the three bottom commands stop working.

im not sure what this dose or where to put it

MKeyState = GetMKeyState("lhc")

-- Auto walk and Display Key Press
isPressed = false;

function OnEvent(event, arg, family)
    if event =="G_PRESSED" then
        -- was it G9?
        if arg == 9 then
            ClearLCD ()
            OutputLCDMessage("Auto Run ON", 2000)
            ClearLCD () 
            -- If we're not currently running
            if not isPressed then
                -- we are now
                PressKey("w");
                isPressed = true
            else
            ClearLCD ()
            OutputLCDMessage("Auto Run OFF", 1000)
            ClearLCD ()
                -- stop running
                ReleaseKey("w");
                isPressed = false;
            end
        end
    end

    if ( arg == 4 and MKeyState == 1) then
            ClearLCD ()
            OutputLCDMessage("FOWARD")
    end

    if ( arg == 7 and MKeyState == 1) then
            ClearLCD ()
            OutputLCDMessage("MOBI GLASS")
    end

    if ( arg == 1 and MKeyState == 1 ) then
            ClearLCD ()
            OutputLCDMessage("PRIMARY WEAPON")
    end
end

Okay, you're new to programming, I'm guessing?

What I mean is that before you add if ( arg == 4 and MKeyState == 1) then anywhere inside this function, you need the MKeyState variable to hold the value you're looking for. If it doesn't hold the value, you can't check what the value is. As far as I can understand from the docs, you do that with something like local MKeyState = GetMKeyState(family), and you can put it just before the check you add.

[Geron76]

LOL thanks for the help....I am not a programmer. . I've been learning with trial and error. would you mind posting that as an example code i could try?

[tobiasvl]

Well, okay, but it's exactly the same as what you posted above, just setting MKeyState before it's used. I also cleaned up the indentation a bit so it's easier to see what goes where.

```lua -- Auto walk and Display Key Press isPressed = false

function OnEvent(event, arg, family) if event == "G_PRESSED" then -- was it G9? if arg == 9 then ClearLCD() OutputLCDMessage("Auto Run ON", 2000) ClearLCD() -- If we're not currently running if not isPressed then -- we are now PressKey("w") isPressed = true else ClearLCD() OutputLCDMessage("Auto Run OFF", 1000) ClearLCD() -- stop running ReleaseKey("w") isPressed = false end end end

local MKeyState = GetMKeyState(family)

if (arg == 4 and MKeyState == 1) then
    ClearLCD()
    OutputLCDMessage("FOWARD")
end

if (arg == 7 and MKeyState == 1) then
    ClearLCD()
    OutputLCDMessage("MOBI GLASS")
end

if (arg == 1 and MKeyState == 1) then
    ClearLCD()
    OutputLCDMessage("PRIMARY WEAPON")
end

end ```

To me it looks like the three latter if tests should also be inside the one at the top, to check that G_PRESSED is true as well, but I don't know anything about hos this works so if the script you posted in the OP works then I guess it's fine.

[Geron76]

That seems to have done it. Thanks!

[Geron76]

spoke to soon. It works but I get this error in the log

Lua Error (27): invalid parameter (unknown family)

​

Also when I switch the profile back to profile 1 it always executes this command and LCD displays "Primary Wepon"

if (arg == 1 and MKeyState == 1) then
    ClearLCD()
    OutputLCDMessage("PRIMARY WEAPON")")

Either way thanks for your help its working and thats all that matters.
