Welcome to the Game Development Using Processing.js Workshop!
Intro (me)
- Seneca college BSD student
- Research assistant in CDOT
- Related projects: C3DL and XB PointStream
- Wordpress, Twitter
Goals & Schedule
- Develop a simple 2D or 3D game using in Processing
- 9-11 Examples and exercises
- 11-12 Work, experiment, collaborate
Processing (aka P5)
- Processing.org
- Open source data visualization language
- Developed in Java
- "Sketches" written using Java syntax
- Requires a JVM plug-in
- Uses the <object> tag
- Reference
- Bug tracking
Setting up Processing
- Download it here
- Save the .DMG file to the Desktop
- Double-click to extract file
- Drag the Processing icon to the desktop
- Double-click the icon to start
Processing.js (aka PJS)
- ProcessingJS.org
- Open source JavaScript port of Processing
- Started by John Resig
- Many contributions by Seneca
- Bug Tracking
- Does not require a plug-in
- Uses the <canvas> tag
- Lots of IDEs Processing.js IDE, HasCanvas, SketchPad, Sketch.Processing.org, My IDE
Setting up Minefield
- Why use it?
- Much faster than Firefox
- Has WebGL
- Download a working version of Minefield here
- Instructions to enabled WebGL here
Setting up Processing.js
- 3 Files Required
- Processing.js file
- Sketch file
- HTML file

Sample Games
Here are some Processing.js games and prototypes to give you an idea what is possible
3D Pong by bmidgley
Tower Defense by Will Larson and Peter Burns
Core by Andor Salga
Light Cycles by Al MacDonald
Game of Life by Al MacDonald
JS Ninja by Al MacDonald
Zelda by Scott Downe
Challenges
Create an empty sketch and try to code a simple game:
Pong!
Concentration
Flying side-scroller
Sokoban
Gotchas
- Integer/Integer division println(5/2) v.s. println(5/2.0)
- NPOT (Non Power of Two) textures will not load in 3D
- color does not use new
