Solved How to add and use simple ui control buttons.

I'm trying to add a few buttons to the simple powertrain control app to control flaps on my plane. I also just want to figure out how to make them show up and trigger local functions. I've tried so many things but it either doesnt show up, or crashes the game.

The lack of documentation is confusing me. I've looked through this thread but it didnt really help: https://www.beamng.com/threads/how-...-on-the-ui-like-the-jato-and-n2o.93584/page-2

Currently i have two print commands that show the function is 'running'. But the button isnt showing up on the ui.

Code:

local function flapToggle()
    print("Setting up flapToggle...")

    flap(1) -- Call the flap function with VALUE = 1 when the button is pressed

end


local function setSimpleControlButtons()
    print("Setting up Simple Control Buttons...")
    extensions.ui_simplePowertrainControl.setButton("flap_toggle ", "Flap Control", "powertrain_jato", "", nil, "print('button clicked!')")
end

And this is where i've gotten with the lua:

And that is replacing the mtngoat_lua.lua file in the plane mod found here: https://www.beamng.com/resources/mtn-goat.29759/https://www.beamng.com/resources/mtn-goat.29759/

Any advice or help would be appreciated, thank you.

 

Take a look at @DaddelZeit's mod https://www.beamng.com/resources/simple-ui-suite.32762/

 

Thank you! I did get it figured out a while ago, i forgot about this thread.
