First off let me say that I like the ED's 'idea' of the new way of programing switches, I just wish it worked but it doesn't. So for now we have to go 'old school' to program. Follow closely cause it can seem overwhelming. I'll treat this as its your first time on the game. - First we need to have a few things, (1) Notepad++ ( to edit Lua files, this is a MUST. Never use the regular notepad to edit thses files) (2) the name of the controller you're going to use, in my case it "BU0836X Interface" - Next goto the main game folder... C:\Eagle Dynamics\DCS World\Mods\Aircraft\A-10C\input\A-10C\Joystick - In there you'll find a file named "Default.lua" right click and copy that file, then paste it on your desktop, and change its name to your controller name. Example... BU0836X Interface.lua Now open that file with notepad++, then click Search on the command bar, then do a search for joy_btn3 or what ever the button number you are going to use. It should look like this.... {combos = {{key = 'JOY_BTN3'}}, down = iCommandPlaneTrimOn, up = iCommandPlaneTrimOff, name = 'Stick to trimmer control mode', category = 'Flight Control'}, then delete the "combos = {{key = 'JOY_BTN3'}},' portion so it now looks like.... {down = iCommandPlaneTrimOn, up = iCommandPlaneTrimOff, name = 'Stick to trimmer control mode', category = 'Flight Control'}, Click File,Save. Now return the cursor ti the top of the file, and do a search for Battery Power it should look like.... {down = iCommandBatteryPower , name = 'Battery power', category = 'Electrical power control panel'}, First thing you're going to do is add the following to the begining... combos = {{key = 'JOY_BTN3'}}, it now looks like.... {combos = {{key = 'JOY_BTN3'}}, down = iCommandBatteryPower , name = 'Battery power', category = 'Electrical power control panel'}, then add the following... ,up = iCommandBatteryPower It now looks like..... {combos = {{key = 'JOY_BTN3'}}, down = iCommandBatteryPower, up = iCommandBatteryPower , name = 'Battery power', category = 'Electrical power control panel'}, Click File/Save Now copy and paste your new lua file to C:\Eagle Dynamics\DCS World\Mods\Aircraft\A-10C\input\A-10C\Joystick folder. Now when you click the toggle on, the battery will turn on, and when you click it off the battery will go off.
