Hello, im creating a racing game in flash where 3 people run along a race track the the finish line. One character will be controlled by the user in which they have to rapidly press 2 button keys as fast as they can to make the racer move. The faster they press the keys, the faster the player will run.
Question: How do i do this? I dont know where to begin, here is an image of my game below, its very basic at the moment.
