This document provides an introduction to programming concepts useful for designing with code, including object oriented programming, frameworks, syntax, classes, objects, functions, variables, and arrays. It explains that arrays allow the creation of multiple variables without defining a new name for each, making the code shorter and easier to read and update. Arrays can store different data types like images or numbers.
![Designing with Code
Arrays
? To make an array, just place brackets after the data type: int[] x;
? The beauty of creating an array is the ability to make 2, 10, or
100,000 variable values with only one line of code. For instance, the
following line creates an array of 2,000 integer variables:
int[] x = new int[2000];
? Arrays can also be made of other data types like images:
PImage[] images = new PImage[32];](https://image.slidesharecdn.com/code1-101021091815-phpapp02/85/Coding-for-8-320.jpg)
![Designing with Code Let the array store
the variables
Arrays
float[] x = new float[3000];
? this examples shows 3000 variables in an array void setup() {
? using repetition loop to work with large arrays keeps the code concise size(240, 120);
? need to know the length of the array smooth();
noStroke();
fill(255, 200);
for (int i = 0; i < x.length; i++) {
x[i] = random(-1000, 200);
}
}
void draw() {
background(0);
for (int i = 0; i < x.length; i++) {
x[i] += 0.5;
float y = i * 0.4;
arc(x[i], y, 12, 12, 0.52, 5.76);
}

- 1. Designing with Code simple intro/review of some useful programming basics design and information architecture/ysdn 3006
- 2. Designing with Code Object Oriented Programming ? OOPs ? Processing, ActionScript, Java, Javascript ? use of objects, functions and methods Frameworks ? jQuery, Tweener, Hype, Papervision, ? a reusable set of libraries or classes for software systems Syntax ? grammar ¡°rules¡± speci?c to each language ? but all OOPs language have some things in common
- 3. Designing with Code Classes ? class de?nes the properties and methods available ? each object falls under a single class ? eg. MovieClip, TextField,Video - ActionScript ? individual object - instance Objects ? smaller building blocks - easier to work with ? way to group variables with related functions ? eg. PImage, PFont, PShape - Processing ? speci?c properties and/or methods
- 4. Designing with Code Class radio } this object is an instance of radio class { volume } properties band setVolume attributes, ?elds setBand methods power setPower actions, behaviours, callout frequency setFrequency
- 5. Designing with Code Functions ? basic building blocks of OOP ? independent units that work together ? eg. background(), size(), stroke()- Processing ? can be built in or custom
- 6. Designing with Code int myWidth = (320*2); int myHeight = (240 + 240); Variables int mySquare = 60; int myCircle = 60; //show the value of a variable in the console ? types of variables - int, ?oat, println(myCircle); ? a holder for value //sometimes you need more info println("myCircle" + myCircle); ? value can be an expression used as parameters // formatting like this is called concatenation println("myCircle" + "" + " ¡ª " + myCircle); background(0); size(myWidth, myHeight ); rect(30, 30, mySquare, mySquare); ellipse(130, 60, myCircle, myCircle); int myWidth = (320*2); int myHeight = (240 + 240); int mySquare = 60; int myCircle = 60; background(0); size(myWidth, myHeight ); rect(30, 30, mySquare, mySquare); ellipse(130, 60, myCircle, myCircle);

- 10. Designing with Code Let the array store the variables Arrays float[] x = new float[3000]; ? this examples shows 3000 variables in an array void setup() { ? using repetition loop to work with large arrays keeps the code concise size(240, 120); ? need to know the length of the array smooth(); noStroke(); fill(255, 200); for (int i = 0; i < x.length; i++) { x[i] = random(-1000, 200); } } void draw() { background(0); for (int i = 0; i < x.length; i++) { x[i] += 0.5; float y = i * 0.4; arc(x[i], y, 12, 12, 0.52, 5.76); } }
