Someone help me make this script how to add a key to press activate?

I made some mistakes in the script I sent you for this so this is the little more fixed version and the key press version. Don't hesitate to ask questions about this or tell me if it doesn't work since I haven't tested it.

Make sure that this is in a LOCAL SCRIPT and not a SERVER SCRIPT and it's located in StarterGui or StarterPlayer > StarterPlayerScripts

Modified Version:

local settings = { --This is a table, this table will store all the variables that you can change.
damageTime = 6, -- How many times It will damage the player
inbetweenTime = .5, -- The time you have to wait until It damages again
damage = 10, -- How much damage it will do
debounce = false,
hitDebounce = false,
timeUntilPunch = 7, -- Change this to the time you want it to wait until you can punch again
}


	repeat wait() until game.Players.LocalPlayer.Character
function onKeyPress(inputObject,gameProcessedEvent)
	settings.debounce = false
    if inputObject.KeyCode == Enum.KeyCode.E and not settings.debounce then
	settings.debounce = true
game.Players.LocalPlayer.Character.HumanoidRootPart.Touched:Connect(function(hit) --[[ This is a function which will fire when it is touched, make sure to put the player you want in the brackets w/ .HumanoidRootPart  --]]
if hit.Parent:FindFirstChildOfClass('Humanoid') and settings.debounce == true then --[[ This will check if it hits something w/ a humanoid --]]
for i = 1,settings.damageTime do
	if not settings.hitDebounce then
		settings.hitDebounce = true
	hit.Parent:FindFirstChildOfClass('Humanoid'):TakeDamage(settings.damage) -- this will take damage
	wait(settings.inbetweenTime) -- this will wait for the time classified in settings.
	settings.hitDebounce = false
	end
end
wait(settings.timeUntilPunch)
settings.debounce = false
end
end)
end
	end

game:GetService('UserInputService').InputBegan:Connect(onKeyPress)
