(Solved): When I press up or down I get 6 guesses

So I am following along and when I press up or down instead of the program making one guess, it executes the guess code six times.

My code:

void Update () {
		if (Input.GetKey(KeyCode.UpArrow)){
			min = guess;
			guess = (max + min) / 2;
			print ("Higher or lower than " + guess + "?");
		}else if (Input.GetKey(KeyCode.DownArrow)){
			max = guess;
			guess = (max + min) / 2;
			print ("Higher or lower than " + guess + "?");
		}else if (Input.GetKey(KeyCode.Return)){
			print("I Won!");
		}
	
	}

Results from console log after pressing the arrow key once:

Is the number higher or lower than 500?

ok so I figured it out a minute after posting. Sorry.

The problem is I needed to use Input.GetKeyDown() and not GetKey()

Isn’t that always the way! :slight_smile:

It’s not a problem, and often these posts serve wonderfully to help other people, as you have outlined what the issue was - thank you :slight_smile:
