Congratulations on completing Unit 1-4! The object of this unit is to teach you how to add the ability to count numbers into your game. At first, this might not sound too exciting. but number counting (counting up or counting down) is very important! It is how you keep score or set a timer. For example, say you are playing a game of air hockey against a friend. The game needs to be able to keep track of the score and know that the first player to "score" 7 goals is the winner. To get started, click the blue button below and have the All About Incrementing Numbers .pdf document available. Then, watch the video tutorials in order to make your incrementing numbers example file. Once you have a working number counter that is free of bugs and glitches, see if you can copy the file or change the programming so that you can count down instead of up. See if you can add a timer or score keeper to a new game or an existing game you have made. Happy game making!
