If you have a framerate of 60, then you'll only need to move half as much each frame as you would if your framerate is 30fps. Now, there's no such thing as units in programming--that's something you need to keep track of. If x and y are defined in meters, and you're moving the player once every second (maybe your framerate is 1fps), then the value of "speed" will be "1.0". If x and y are in meters, and you're moving the player 47 times per second (maybe your framerate is 47fps), then the value of "speed" will be "0.0213". These values will produce the same apparent speed to the user. Basically, just think about it, and do what makes sense. That's what programming is all about. Ian
