![]() This method sets the necessary variables to start the game if we are on the initial screen when clicked, start the game Display the contents of the current screen We control which screen is active by settings / updating With that said, here is what our skeleton code looks like: /********* VARIABLES *********/ Whenever we want to change the screen, we will change that variable to the identifier of screen we want it to display. In the draw block, we will have an if statement that checks the variable and displays the contents of the screen accordingly. We then draw the contents of the correct screen depending on the variable. We will have a global variable that stores the information of the currently active screen. So the question arises, how do we make Processing show the correct page at the correct time?Īccomplishing this task is fairly simple. Then, we will handle different screens (initial screen, game screen, game over screen etc.). For starters, we will write our setup and draw blocks as usual, nothing fancy or new. The first step is to initialize our project. Building Flappy Pong Processing Tutorial Step #1: Initialize & Handle Different Screens I advise you to follow the article, grab the full code, play with it on your own, start thinking about your own game as quickly as possible, and start implementing it. I did my best to keep this Processing tutorial organised and simple. As we move along, you’ll see how the code gets complicated really fast. Without using object-oriented programming (OOP) concepts, it is not easy to build complex games, such as platform games with multiple levels, players, entities etc. These concepts include gravity, collisions, keeping scores, handling different screens and keyboard/mouse interactions. This is based on my experience from when I was a teaching assistant, helping new programmers learn how to use Processing. The reason I picked a game like this is that it has most of the concepts that beginners struggle with when learning game development. The game we will build in this Processing tutorial is sort of a combination of Flappy Bird, Pong and Brick Breaker. If you have any questions, be sure to leave a comment. Java Mode (Not available until Processing 1.Before we begin the Processing tutorial, here is the code of the DVD logo exercise from the previous part. ![]() Rect(width-mouseX, height-mouseY, 50, 50) ![]() ![]() Method is in setup() because it's only needed once. Note also that the call to the background() This example draws rectangles that follow the mouse position (stored in The loop() section runs forever until the program is stopped. This mode provides an optional setup() section that is run once when the program begins. Processing allows people to program within three levels of complexity: If your program is 320 pixels wide and 240 pixels high, coordinate is the upper-left pixel and coordinate is in the lower right. Processing uses a Cartesian coordinate system with the origin in the upper-left corner. It is possible to run, stop, save, open, and export files. When the "run" button is pushed, the programĬompiles and plays in the graphic window. The Processing Environment consists of an integrated text editor and display Processing 1.0 _ALPHA_ > Environment (IDE) ![]()
