FSUIPC: Lua Tutorial
For Microsoft Flight Simulator and GoFlight Equipment

Cleaning Up

    Referring to the Last chapter's Lua file named "PitotHeat.Lua", this is what we had...

function PitotHeat(offset, value)
    model = GFT8
    unit = 0
    id = 1
    if value == 1 then
        gfd.SetLight(model, unit, id)
    else
        gfd.ClearLight(model, unit, id)
    end
end
event.offset("029C", "UB", "PitotHeat")
 

    If your comfortable with remembering which parameters are for what we can slim down the code and instead of variables, we can use direct values as shown below...

function PitotHeat(offset, value)
    if value == 1 then
        gfd.SetLight(GFT8, 0, 1)
    else
        gfd.ClearLight(GFT8, 0, 1)
    end
end
event.offset("029C", "UB", "PitotHeat")
 

    If you'd like to keep them as is, that's fine.  It won't make any difference to FSUIPC. but let me show you how to make "comments' in your code.

function PitotHeat(offset, value) -- Beginning of the function
    if value == 1 then -- Checks to see if value equals one
        gfd.SetLight(GFT8, 0, 1) -- Turns ON light#1, of unit#0 on the GFT8
    else
        gfd.ClearLight(GFT8, 0, 1) -- Turns OFF light#1, of unit#0 on the GFT8
    end -- end of the "if...then" statement
end -- end of the function
event.offset("029C", "UB", "PitotHeat")
 

    Anything after the two "--" will be ignored by FSUIPC. If you do want to slim down your code, but don't want to forget what the parameters are you can modify your code like this...

function PitotHeat(offset, value)
    if value == 1 then
        gfd.SetLight(GFT8, 0, 1) -- (model, unit, id)
    else
        gfd.ClearLight(GFT8, 0, 1)
    end
end
event.offset("029C", "UB", "PitotHeat")
 

    There, now that's nice and neat and you can see what the parameters are for.
