How to reference Left Control button detection with Mouse.Keydown event

Help and Feedback Scripting Support
#1

I’m attempting to create a sci-fi game with a friend of mine with a flight system that has essentially a flight seat provided by MaxR3d with some modifications of our own in order to increase the functionality (warp speed, velocity changes etc etc) and we are currently trying to reference the left control button but apparently I’ve had trouble finding out how to do so without substantially modifying any of the functions within the main script as I do not want to have to rework and possibly break it. Here’s the function and the main keys just for reference (0, or shift rather increases the ship velocity and z at the moment decreases it):

mouse.KeyDown:connect(function(key)
if key == "0" then
		veri = 0.006
	end
if key == "z" then
		veri = -0.006
    end

again I do not wish to go through the headache of having to rework any of the functions any more than I need to mainly due to the circumstance that I have not in any way had prior experience in handling KeyDown functions or even UserInputService for that matter. If it’s unavoidable that I’ll need to implement userinputservice instead, please let me know but otherwise I would like to know if there’s a string identification for left control.

TL;DR: Not experienced with KeyDown/UserInputService, played around/modified MaxR3d’s enhanced flight seat and need a string identifier for left control instead of using z if possible or other solution if necessary

Don’t know if you need the rest of the code but you can find the model here and check the script for yourself: (14) Enhanced Flight Seat - Roblox

I know you have no experience with UserInputService but it’s really simple:

game:GetService("UserInputService").InputBegan:Connect(function(key, processed)
   if processed then return end -- this checks if the player is typing in a textbox or pressing a button

   if key.KeyCode == Enum.KeyCode.LeftControl then -- checks if the left mouse button was pressed
     -- do stuff
   end
end

You would have to use UIS or ContextActionService at some point anyway since Mouse and Mouse.KeyDown are both deprecated (doesn’t mean removed).

I changed and implemented userinput service as of today, however; now the script won’t even prompt changes in the body velocity velocity values when the player presses down on the correct keys. I’ll press w to go forwards or s to go backwards but nothing happens. Can you explain this?
