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 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

Basiscs

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 (+error console)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

3D

X - box Example

X - sphere, sphereDetail Example

X - Vertex

X - Texture Example

Debugging

using println, checking in P5, error console

DOM Manipulation/Library Integration

DOM Interaction Example

Integration with jQueryUI - Example

Audio Example, Audio Data API Demos

Physics using Box2DJS - Al MacDonald's Demo, 0.1 PJS Crayon Physics

More demos! My PJS Web IDE (Visualizations, Spatial hierarchies, Image manipulation, Particle Systems!)
