I cannot over stress the importance of writing a system specification. A specification doesn t have to be a multipage document with droning on paragraphs containing shalls,

shoulds, musts, wills, etc. For a large, multipart system, it may very well go into the tens or even hundreds of pages. There could be design reviews, teams working on different sections, code reviews, and all the other things associated with large companies. How big should your specification for the Pong game be The correct answer is it depends. But that doesn t help you. I m going to go out on a limb here and say that you want your specification to be two pages. Wow! You made a commitment. Two pages. So what s on those two pages

Let s make one page some sketches of our game: you ll have a rectangle to act as your playing surface you ll probably want to make it a similar green color to a real table tennis game table. There should be lines on it like there are on a real table, as you can see in Figure 5 1.

Okay, you ve got a good start. You ve established your playing surface and it has the general look of a table tennis table. Your player and opponent sides have been defined. NOTE: Wonder why I call it table tennis and not Ping-Pong The name Ping-Pong actually belongs to the game company Parker Brothers, whereas the term table tennis is the actual name of the game as defined by the International Table Tennis Federation (ITTF). The approximate positions of the paddles are also set. Is this enough For that you have to ask yourself some questions. First, how will you initiate game play You could just tap the screen, but that s too easy. Saying that is like saying Oh yeah, it s in there, I just

didn t show it because it was obvious. Here s the thing. Nothing is obvious when you re buried in code, it s late, you re tired, and have deadlines to meet. There s a saying in playwriting: if it s not on the page, it s not on the stage. This means, if it s not written down, you won t be seeing it. The key point write it down! You also need to keep score and show it to the player. So you have to add the score somewhere, and, the labels indicating which score belongs to whom. How do the paddles move You talked about this earlier, but you didn t show it. For simplicity you re going to have the paddles move only to the left and to the right to work with the potentiometer on your game controller. There are also some less obvious things. Does the game table take up the whole screen or is it smaller Here you need to think about how realistic you want your game to be. A regulation table is nine feet long by five feet wide or simply nine by five. The iPhone screen is 480 by 320, or reducing that, three by two. The dimensions don t match. They re close if you multiply the iPhone screen dimensions by three, you get nine by six. But that s still not nine by five. This is where it becomes a judgment call. Normally, I would take the safe route the technically safe route and make the playing surface match the iPhone s screen dimensions. You don t have to worry about what s outside the table bounds and can even choose to either let the ball continue out or have it bounce back into play as if the edges were a wall. Like I said, that s normally what I d do. For this exercise, I m going to stick with a table that retains the nine by five dimensions and place it inside a virtual room. My feeling on this is that, when you play table tennis, you move far to the left and right of the table to make shots with significant angles. This differs from a game like air hockey where you are constrained by the sides of the playing surface. The thing is, in air hockey, you re aiming for a small target and the reduced set of angles makes sense. Your opponent only has to guard a small, central area. But in your table tennis type of game, you open up the playing field with much wider margins. Like you, your opponent can move to extreme angles to win the point, so you re going to let that happen in your game. Anything else Hmmm, let s think about it. You ve decided on the table dimensions, restricted the player s paddle movements to left and right, you added scoring. Is anything missing It may sound overly detailed, but you need to add the ball to the drawing. Trust me. It s a very small thing to add and it makes your diagram complete. Now let s take a look at your revised drawing in Figure 5 2. All the elements just described have been added to make things a little more clear. You added both the player s and computer s score along with labels to tell which is which. You added a serve button, the ball, and an example movement line. You added a separate rectangle around the playing surface to indicate that the table is within the iPhone screen bounds, and you added a ball. Let s cheat and see what the final game is going to look like to see how close you need to be on your spec drawing. Looking at Figure 5 3 you can see that the drawing very closely represents what is in your final Pong game.
