Computer Programming-Help?

If you look at the source code by adding "view-source:" infront of the website

(view-source:http://www.cs.unm.edu/~joel/cs105/src/CS105_Lab2_B...

The ball is movement randomly

var speedX = 5*Math.random() - 5*Math.random();

var speedY = 5*Math.random() - 5*Math.random();

What move the ball is:

ballX = ballX + speedX;

ballY = ballY + speedY;

I don't know any javascript, but just above the code:

ballX = ballX + speedX;

ballY = ballY + speedY;

change speedX and speedY by the keypressed:

pseudo code!!!

If up arrow key pressed

speedY = speedY + 1

If down arrow key pressed

speedY = speedY - 1

If left arrow key pressed

speedX = speedX - 1

If right arrow key pressed

speedX = speedX + 1

Ok
