How do you make a keyboard input "automatic"?

I'm trying to make a rail shooter game (like star fox) but I ran into one problem. The player has to "mash" one of the moving keys, as opposed to how I wanted it where they can just hold the key down.

code inside of a local script, which has been placed in the starter pack

01local BodyPositionPosX = 8
02local BodyPositionPosY = 1
03function onKeyPress(inputObject, gameProcessedEvent)
04    if inputObject.KeyCode == Enum.KeyCode.A then
05        BodyPositionPosX = math.min((BodyPositionPosX + 2), 24)
06        game.Workspace.Part.BodyPosition.position = Vector3.new(BodyPositionPosX,BodyPositionPosY,19)
07 
08    elseif inputObject.KeyCode == Enum.KeyCode.D then
09        BodyPositionPosX = math.max((BodyPositionPosX - 2), -16)
10        game.Workspace.Part.BodyPosition.position = Vector3.new(BodyPositionPosX,BodyPositionPosY,19)
11 
12    elseif  inputObject.KeyCode == Enum.KeyCode.W then
13        BodyPositionPosY = math.min((BodyPositionPosY + 2), 24)
14        game.Workspace.Part.BodyPosition.position = Vector3.new(BodyPositionPosX,BodyPositionPosY,19)
15 
16    elseif inputObject.KeyCode == Enum.KeyCode.S then
17        BodyPositionPosY = math.max((BodyPositionPosY - 2), 0)
18        game.Workspace.Part.BodyPosition.position = Vector3.new(BodyPositionPosX,BodyPositionPosY,19)
19 
20    end
21end

Use input ended event User#5423 17 — 9y

I tried switching it and it only activated when you let go of the button not automatic gaberdell 71 — 9y

Guess what, I DID IT!

You need to use the InputEnded to see if the input that was ended is the current key so, we create a variable runrepeat and a variable currentkeycode Then, when a key is pressed, we use a repeat loop, and wait for the key to get InputEnded!

Here's the code (I tested it!):

01local BodyPositionPosX = 8
02local BodyPositionPosY = 1
03local runrepeat = false
04local currentkeycode
05function onKeyPress(inputObject, gameProcessedEvent)
06    if inputObject.KeyCode == Enum.KeyCode.A then
07        currentkeycode = Enum.KeyCode.A
08        runrepeat = true
09        repeat
10            BodyPositionPosX = math.min((BodyPositionPosX + 2), 24)
11            game.Workspace.Part.BodyPosition.position = Vector3.new(BodyPositionPosX,BodyPositionPosY,19)
12            wait(0.3) --[[ Give time for key to go 'up' ]]
13        until runrepeat==false
14 
15    elseif inputObject.KeyCode == Enum.KeyCode.D then
16        currentkeycode = Enum.KeyCode.D
17        runrepeat = true
18        repeat
19            BodyPositionPosX = math.max((BodyPositionPosX - 2), -16)
20            game.Workspace.Part.BodyPosition.position = Vector3.new(BodyPositionPosX,BodyPositionPosY,19)
21            wait(0.3)
22        until runrepeat==false
23    elseif  inputObject.KeyCode == Enum.KeyCode.W then
24        currentkeycode = Enum.KeyCode.W
25        runrepeat = true
26        repeat
27            BodyPositionPosY = math.min((BodyPositionPosY + 2), 24)
28            game.Workspace.Part.BodyPosition.position = Vector3.new(BodyPositionPosX,BodyPositionPosY,19)
29            wait(0.3)
30        until runrepeat==false
31    elseif inputObject.KeyCode == Enum.KeyCode.S then
32        currentkeycode = Enum.KeyCode.S
33        runrepeat = true
34        repeat
35            BodyPositionPosY = math.max((BodyPositionPosY - 2), 0)
36            game.Workspace.Part.BodyPosition.position = Vector3.new(BodyPositionPosX,BodyPositionPosY,19)
37            wait(0.3)
38        until runrepeat==false
39    end
40end

42function onKeyUp(inputObject, gameProcessedEvent)
43    if inputObject.KeyCode == currentkeycode then
44        runrepeat=false
45        currentkeycode = nil
