I’m planning on using the Java 2D API for a project this summer, but I need to get familiarized first. In the previous post I covered Pong on a the C32 microcontroller<\/a>. Here I’ll look at a desktop implementation using AWT.<\/p>\n

A great starting point is this zetcode tutorial<\/a> on game programming. The author covers a series of classic arcade games. I used their code to figure out how to initialize the Swing JPanel and handle keyboard input.<\/p>\n

Here’s my implementation:

Controls<\/strong>
\nPlayer 1: Q, A
\nPlayer 2: Up, Down
\nPause: Space
\nRestart: Esc<\/p>\n

The collision detection code is almost exactly the same as the C version. This version is a little more robust in that it supports arbitrary window sizes, paddle lengths\/widths\/speeds, and ball velocities. The only real trouble spots were devising a scheme to handle two keys being held down simultaneously and repainting the frame at the correct times. For more fun, consider modifying this version to change the X and Y speeds of the ball based on paddle velocity or collision position.<\/p>\n

Here’s the playable jar file<\/a> and the Eclipse project<\/a> with the source.<\/p>\n
