Ok I am currently working on the last bit of my program and it needs to include the lastDistance and currentDistance forumla to tell the user whether their current guess is closer or further from the actual number.
Here is what is required, I have no idea how to start it or where I need to place it.
To turn the text field red or blue I have two variables in my program: lastDistance and currentDistance. You set last distance and current distance when you make the first guess. For example if you guess 500 and the actual number is 700, the distance is 200. Let's say the next time you guess 300 so the current distance is 400. Compare that to the last distance. It is greater so you turn the text field blue (you are getting colder). Now put the current distance in last distance. Next time you guess 600. The currect distance is 100 which is less than the last distance so turn the text field red (you are getting warmer).
