void setup() { size( 500, 500 ); smooth(); } void draw() { fill( 200, 150, 200 ); ellipse( random(500), random(500), 80, 80 ); // fill( 200, 0, 250 ); // rect( mouseX, 100, 80, 80 ); }
Random Circles with Varying Size and Color
void setup() { size( 500, 500 ); smooth(); } void draw() { fill( 200, random(255), mouseX/2 ); ellipse( random(500), random(500), mouseX, mouseX ); // fill( 200, 0, 250 ); // rect( mouseX, 100, 80, 80 ); }
Random Circles in Square Areas
void setup() { size( 500, 500 ); smooth(); } void draw() { fill( 200, random(255), mouseX/2 ); ellipse( random(100,200), random(100,200), mouseX, mouseX ); fill( 200, mouseX/2, random(255) ); ellipse( random(300,400), random(300,400), mouseX, mouseX ); }
Switching between rectangles and circles on mousePressed
void setup() {
size(480, 480 );
smooth();
}
void draw() {
//background( 200 );
if ( mousePressed == true ) {
fill( 231, 47, 39 ); // red
ellipse(mouseX, mouseY, 80, 80);
}
else {
fill( 255, 200, 8 ); // orange
rect(mouseX, mouseY, 80, 80);
}
}
Tall-skinny, vs. short-wide Rectangles
void setup() {
size(480, 480 );
smooth();
}
void draw() {
//background( 200 );
if ( mousePressed == true ) {
fill( 231, 47, 39 ); // red
rect(mouseX, mouseY, 200, 20);
}
else {

rect(mouseX, mouseY, 20, 100);
}
}
Drawing lines on mousePressed
void setup() {

smooth();
}
void draw() {
//background( 200 );

line( mouseX, mouseY, pmouseX, pmouseY );
}
}
Vertical Circles
void setup() {
size( 400, 400 );
smooth();
}
void draw() {
background(200);
// count from 20 to 380 jumping 20 each time.
for( int x = 20; x < 400; x = x + 20 ) {
// and draw a circle in that position, on a horizontal line.
fill( 250, 200, 8 );
ellipse( 200, x, 15,15 );
}
}
Diagonal of Orange Circles
void setup() { size( 400, 400 ); smooth(); } void draw() { background(200); fill( 250, 200, 8 ); // count from 20 to 380 jumping 20 each time. for( int xy = 20; xy < 400; xy = xy + 20 ) { // and draw a circle in that position, on a diagonal line // where x and y have the same value. ellipse( xy, xy, 15,15 ); } }
Cross of Orange Circles
void setup() { size( 400, 400 ); smooth(); } void draw() { background(200); // count from 20 to 380 jumping 20 each time. for( int x = 20; x < 400; x = x + 20 ) { // and draw a circle in that position, on a horizontal line. fill( 250, 200, 8 ); ellipse( 200, x, 15,15 ); ellipse( x, 200, 15,15 ); } }
