Processing to p5.js converter "This is a find/replace converter for
turning simple Processing sketches into p5.js code."
What this converts:
What this converts:
size
void
int [] arrayname = new int [number]
pushMatrix(), pushStyle
popMatrix, popStyle
mousePressed
frameRate
createCanvas
function
var arrayname = new Array(number);
push()
pop()
mouseIsPressed (but leaves mousePressed() alone)
frameRate()
A
faire en plus:
color machin;
Attention int(...) est remplacé par var(...)
Attention float(...) est remplacé par var(...)
Attention PVector est remplacé par var
PVector Toto = new PVector(0,0);
PVector[] Titi = new PVector[num];
...
Titi[i] = new PVector(0,0);
Police = createFont("Helvetica-Light.otf", 24);
for (int j = 0
.length()
if (str1.equals(str2))
keyCode == RIGHT
idem UP, DOWN, LEFT
img1.pixels[y*img1.width+x]
var machin;
remettre int(...)
remettre float(...)
mettre p5.Vector ou createVector:
var Toto = new p5.Vector(0,0);
ou var Toto = createVector(0,0);
var Titi = new Array(num);
...
Titi[i] = new p5.Vector(0,0);
Supprimer var dans function Toto (var i);
Police = loadFont("Helvetica-Light.otf");
for (var j = 0
.length
if (str1 == str2)
keyCode == RIGHT_ARROW
idem UP_ARROW, DOWN_ARROW, LEFT_ARROW
img1.get(x, y)
Ajouter:
updatePixels(); aprés des instructions au niveau pixel.function preload() {
loadImage() loadFont() loadTable() loadStrings()
}

Exemple: class
"ex_10_1_b" From
Make: Getting Started with Processing by Casey Reas and Ben Fry
void setup(){
size(480, 120);
bug = new JitterBug(width/2, height/2, 20, 2.5);
}
void draw(){
bug.move();
bug.display();
}
class JitterBug{
float x;
float y;
int diameter;
float speed;
JitterBug(float tempX, float tempY, int tempDiameter, float tempSpeed){
x = tempX;
y = tempY;
diameter = tempDiameter;
speed = tempSpeed;
}
void move(){
x += random(-speed, speed);
y += random(-speed, speed);
}
void display(){
ellipse(x,y,diameter,diameter);
}
}
function setup() {
createCanvas(480, 120);
bug = new JitterBug(width / 2, height / 2, 20, 2.5);
}
function draw() {
bug.move();
bug.display();
}
function JitterBug(tempX, tempY, tempDiameter, tempSpeed) {
this.x = tempX;
this.y = tempY;
this.diameter = tempDiameter;
this.speed = tempSpeed;
this.move = function() {
this.x += random(-this.speed, this.speed);
this.y += random(-this.speed, this.speed);
};
this.display = function() {
ellipse(this.x, this.y, this.diameter, this.diameter);
}
}
Exemple: Audio input (Microphone etc...)
Minim minim;
AudioInput in;
void setup(){
minim = new Minim(this);
in = minim.getLineIn();
}
void draw(){
in.bufferSize()
in.left.get(i)
}
function setup() {
micro = new p5.AudioIn()
micro.start();
}
function draw() {
micLevel = micro.getLevel();
}
p5.AudioIn
Exemple: Pixel
pixels[x + (y * width)] = color(123);
Couleur = Image.pixels[x + (y * width)];
updatePixels();
set(x, y, color(123));
Couleur = get(x, y);
updatePixels();
