‘’Friction’’ — This can be ON or OFF. If the friction is on, the puck will have a tendency to slow down while travelling across the board. You may notice that it sometimes curves as it slows down. This is because I used integer values instead of floating point. This means that the motion is not 100 percent accurate, resulting in the curved motion of the puck.

‘’Velocity’’ — This can be 2 through 9 and indicates the maximum velocity of the puck. Option 2 is slowest; 9 is fastest.

‘’Bounce’’ — This can be 0 through 9, indicating the amount of “bounce" to the puck, or how well it retains velocity after hitting the side of the board. A 9 means that the puck will not slow down on collision; 0 indicates very little bounce and will cause the puck to slow down considerably if it hits the sides.

‘’Win’’ — This is the score up to which the player(s) will play. It can be from 10 to 90, in increments of 10.

‘’Players’’ — Either 1 or 2. If one paver is selected, then the player should use joystick port 1 and control the top player; the computer will control player two, the bottom player. If two players are selected, then it's the same, except that player two will be controlled by joystick port 2.

I figured that a good way to utilize Action!‘s speed was to write some kind of fast-paced, arcade-type game. But I didn't want to write another space game or __Pac-Man__. I wanted to write something different and unique. __Air Hockey__ may not be a completely unique game (it is similar to __Pong__). but it's different, and a change of pace from “Laser the Aliens”

# I wanted more options and a complete title song, but time and a willingness to work (or the
lack thereof) got in the way.
# Everyone, including myself, thought that the paddles should have been round. But that re-
quires physics. . .I barely passed physics. If I'd made the paddles round, as they are in real life, I would have had to resort to "real" physics instead of the chintzy method I did use.
In physics, you use vectors to describe how objects move, but this is a difficult thing in integers (well, difficult for me), which is what I was stuck with in Action! So I simply gave a
horizontal and vertical speed and a horizontal and vertical direction.

These two compromises, however, were not as difficult or as important as my final compromise. I had to compromise on the one aspect, the most difficult thing, that every programmer must: completion of my goal. I had to stop work on a program which I felt
was incomplete and short of my goals, and call it finished.

I realized that I would continue creating goals as long as I was working on it; I would never finish the game. I'd sit, perma-bonded to my video screen, for the next ten years working on __Air Hockey__ until it was 3-D, talked and had instant replay, a high score list, a theme song to put "Flight of the Valkyries" to shame, and a thousand other things... and I would
still want to change something.

I think the important thing here is to realize that, when you want to write a program, you should decide exactly what it will be like, so that you can say it is finished when it meets the description. I certainly did not. l designed and wrote it as I went along (this is painfully evident to me in the lack of unity and consistency in the program, the "patchwork
quilt" look).

This has also led to my big problem: because the program is so disorganized, I invariably come to some sort of dead end and drop the project. I completely gave up on __Air Hockey__ many months back, but, at the urging of two of my friends (D.S. and D.B.), I
picked it up again and trudged through the tangled code to finish it. . .finally. This is what has kept me from finishing the other hundred or so projects I have stored away in dusty disk files.
