Week 12: Noise + Functions + Key Pressed + Silly Poetry Generator
In Class Task 1: Noise Review
The task was to create two boxes randomly move in a specific section of the screen while changing size and color. All while using noise.
//week 12 task 1
float x, y, w, h;
float x2, y2, w2, h2;
float hue, hue2, s, s2, b, b2;
color col;
void setup() {
size(400, 400);
rectMode(CENTER);
colorMode(HSB);
col=color(random(255), random(255), random(255));
}
void draw() {
background(col);
noStroke();
fill(hue, s, b);
x=map(noise(0.01*frameCount), 0, 1, 100, 250);
y=map(noise(0.01*frameCount+5), 0, 1, 100, 250);
w=map(noise(0.01*frameCount+25), 0, 1, 10, 150);
h=map(noise(0.01*frameCount+45), 0, 1, 20, 150);
hue=map(noise(0.01*frameCount+55), 0, 1, 0, 255);
s=255;
b=255;
rect(x, y, w, h);
noStroke();
fill(hue2, s2, b2);
x2=map(noise(0.01*frameCount+70), 0, 1, 100, 350);
y2=map(noise(0.01*frameCount+80), 0, 1, 100, 350);
w2=map(noise(0.01*frameCount+90), 0, 1, 10, 150);
h2=map(noise(0.01*frameCount+95), 0, 1, 20, 250);
hue2=map(noise(0.01*frameCount+100), 0, 1, 0, 255);
s2=255;
b2=255;
rect(x2, y2, w2, h2);
stroke(255, 200);
line(x, 0, x, height);
line(x2, 0, x2, height);
line(0, y, width, y);
line(0, y2, width, y2);
}
void keyPressed() {
if (key=='s') {
int random_number=int(random(1000));
save(random_number+"robert.george"+"_week12task1"+".png");
}
}
In Class Lesson 1: Function
Something new I learned was how to use functions. Functions are an easier way to group together a block of code under one name. Here is the simple ball bounce animation but using functions instead of having all the code written out in draw.
// bouncing ball - functions
float x=0;
float y=0;
float xSpeed=5;
float ySpeed=3;
void setup() {
size(400, 300);
}
void draw() {
background(255);
//display ball function
displayBall();
//move ball function
moveBall();
//check edges function
checkEdges();
}
void displayBall() {
stroke(0);
fill(0);
ellipse(x, y, 30, 30);
}
void moveBall() {
x=x+xSpeed;
y=y+ySpeed;
}
void checkEdges() {
if ( (x>width) || (x<0) ) {
xSpeed=xSpeed*-1;
}
if ( (y>height) || (y<0) ) {
ySpeed=ySpeed*-1;
}
}
In Class Lesson 2: Fading Typewriter
I also learned how to use keyPressed() to create a typing effect that fades each letter after it has been typed.
//Fading type writer
void setup(){
size(400, 400);
background(#E3D427);
}
void draw(){
//rect same size and color as canvas and with opacity
fill(#E3D427, 20);
noStroke();
rect(0, 0, width, height);
}
void keyPressed(){
fill(#2770E3);
textSize(random(20, 200));
text(key, random(width), random(100, height));
}
In Class Lesson 3: Silly Poem Generator
Next I learned how to create a poem generator by using string arrays and functions. These will be used to generate my own poem generator in the next couple posts.
// the simple silly poem generator
//string arrays count from [ 0, 1, 2, 3, 4, etc. ]
String[] art={"the", "this", "that", "one"};
String[] adj={"green", "red", "unbelievable", "infinite", "pouting"};
String[] noun={"tree", "forest", "dog", "sky", "grass", "mountain"};
String[] verb={"is weeping", "runs", "is thinking", "observes"};
String[] pre={"over", "above", "behind", "in front of"};
int y = 50;
void setup() {
size(500, 400);
background (255);
fill(#CC27E3);
new_sentence();
}
//the green tree is weeping over a pouting dog
void new_sentence() { //a function
background (255); //reset the background
y=50; //reset the y so the poem will restart
write_word(art);
write_word(adj);
write_word(noun);
write_word(verb);
write_word(pre);
write_word(art);
write_word(adj);
write_word(noun);
}
void draw() {
}
void mousePressed() {
new_sentence();
}
void write_word(String[]words) { //a function
int n=(int)random(words.length);
textSize(random(20,40));
text(words[n], random(80, 300), y);
y=y+40; //sets the leading of the words
}
