Game Development Using Processing.js
Intro (me)
- Seneca college BSD student
- Research assistant in CDOT
- Related projects: C3DL and XB PointStream
- Wordpress, Twitter
Goals
- Develop a simple 2D or 3D game using in Processing
Processing (aka P5) Processing.org
- Open source data visualization language
- Developed in Java
- "Sketches" written using Java syntax in the PDE
- Requires a JVM plug-in
- Uses the <object> tag
- Bug tracking
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
Setting up Minefield
- Minefield is much faster than Firefox
- 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
Coordinate system
- size() sets canvas dimensions
- top-left corner [0, 0]
- X increases right
- Y increases downwards
Basics
1 - size, background, rect Example
2 - setup Example
3 - draw, noStroke, ellipse, fill, mousePressed Example
4 - line, stroke, strokeWeight Example
5 - ArrayList Example
Input
6 - mousePressed, mouseReleased, println, debugging with P5 Example
X - keyPressed, keyCode, keyReleased Example
Transfomations
7 - transforms, triangle, rect, (point)
8 - more transforms
9 - 2D Vectors (dot, mult, etc.)
10 - class (?)
11 - type demo (text, textWidth)
12 - PImage, timing, random
13 - Particle System Example
3D
X - box Example
X - sphere, sphereDetail Example
X - Vertex, Texture Example
Debugging
println Example
Checking in P5
Error console
DOM Manipulation/Library Integration
DOM Interaction Example
Integration with jQueryUI - Example
Audio Example, Audio Data API Demos
