Wait Until A Certain Key Is Pressed?

I’m essentially creating a dialouge system, and I want the dialogue to progress when the player hits Enter on their keyboard. My issue right now is that you have to hit Enter twice before the dialouge progresses, and I can’t figure out why. Here’s the code for both the event that processes the key press, and the piece of code that reacts to it:

--Debounce variable
local continueDialouge = false

--Basic function to detect when the enter key is pressed
UserInputService.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.Return then
		continueDialouge = true
		
		wait()
		
		continueDialouge = false
	end
end)

--Waiting until the key is pressed
repeat wait() until continueDialouge

Can anybody explain to me why this is happening? Thanks.

What does this even do??

That part’s to be sure that the other functions read the boolean value in time.

Well, you should use a boolvalue instead. Use :GetPropertyChangedSignal(“Value”), and not repeat wait() until continueDialouge

Use UserInputService.InputBegan:Wait, it’ll return the passed arguments through the event and yield until InputBegan is fired.

-- waiting until a key is pressed
local input = UserInputService.InputBegan:Wait()

-- check if its the right key
if input.KeyCode == Enum.KeyCode.Return then
    -- do stuff
end

Or this incase a user accidentally presses the wrong key.

while true do
	local input = UserInputService.InputBegan:Wait()

	if input.KeyCode == Enum.KeyCode.Return then
		break
	end
end

-- do stuff

But how would I loop it back through (wait again) if they don’t click the Enter key?

If you mean check again if they didn’t click the key, then the second example should work for that.
