Then, we will handle different screens initial screen, game screen, game over screen etc. So the question arises, how do we make Processing show the correct page at the correct time?

Accomplishing this task is fairly simple. We will have a global variable that stores the information of the currently active screen. We then draw the contents of the correct screen depending on the variable. In the draw block, we will have an if statement that checks the variable and displays the contents of the screen accordingly. Whenever we want to change the screen, we will change that variable to the identifier of screen we want it to display.

With that said, here is what our skeleton code looks like:. This may look scary at first, but all we did is build the basic structure and separate different parts with comment blocks. As you can see, we define a different method for each screen to display. In our draw block, we simply check the value of our gameScreen variable, and call the corresponding method.

The first line of this method changes gameScreen variable to 1, the game screen. If this is understood, the next step is to implement our initial screen. To do that, we will be editing the initScreen method. Here it goes:. But when we click, nothing happens.

The background is still black for the same reason. Now, we will start working on the game screen. We will first create our ball. We should define variables for its coordinates, color and size because we might want to change those values later on. For instance, if we want to increase the size of the ball as the player scores higher so that the game will be harder.

We will need to change its size, so it should be a variable. We will define speed of the ball as well, after we implement gravity. We defined the coordinates as global variables, created a method that draw the ball, called from gameScreen method.

Only thing to pay attention to here is that we initialized coordinates, but we defined them in setup. The reason we did that is we wanted the ball to start at one fourth from left and one fifth from top. There is no particular reason we want that, but that is a good point for the ball to start. So we needed to get the width and height of the sketch dynamically. The sketch size is defined in setup , after the first line.

Now implementing gravity is actually the easy part. There are only a few tricks. Here is the implementation first:. Hold your horses, physicist. Instead, this is more of an animation process than anything. The variable we defined as gravity is just a numeric value—a float so that we can use decimal values, not just integers—that we add to ballSpeedVert on every loop.

And ballSpeedVert is the vertical speed of the ball, which is added to the Y coordinate of the ball ballY on each loop. We watch the coordinates of the ball and make sure it stays in the screen. For now, our ball only moves vertically. So we watch the floor and ceiling boundries of the screen. To make the ball bounce, we simply move the ball to the exact location where it had to bounce and multiply the vertical speed ballSpeedVert with -1 multiplying with -1 changes the sign.

So the ball immediately changes its direction with the same speed. Then, as we add gravity to ballSpeedVert and ballSpeedVert has a negative value, it starts to get close to 0 , eventually becomes 0 , and starts increasing again. That makes the ball rise, rise slower, stop and start falling. There is a problem with our animation process, though—the ball keeps bouncing.

If this were a real-world scenario, the ball would have faced air resistance and friction every time it touched a surface. We add the following:. As the name suggests, friction is the surface friction and airfriction is the friction of air. So obviously, friction has to apply each time the ball touches any surface.

So in those methods, we did the same thing, only this time with friction. Now we need a racket for the ball to bounce on. We should be controlling the racket.
