As a test, I ran this code from Casey and ben's Book Processing, 47-07. It also causes my computer clock time to speed up about 125%.
// Requires the Button class
Button button1, button2, button3;
int mode = 1;
void setup() {
size(100, 100);
smooth();
color gray = color(204);
color white = color(255);
color black = color(0);
button1 = new Button(10, 80, 10, gray, white, black);
button2 = new Button(25, 80, 10, gray, white, black);
button3 = new Button(40, 80, 10, gray, white, black);
}
void draw() {
background(204);
manageButtons();
noStroke();
fill(0);
if (mode == 1) {
ellipse(0, 40, 60, 60);
} else if (mode == 2) {
ellipse(50, 40, 60, 60);
} else if (mode == 3) {
ellipse(100, 40, 60, 60);
}
}
void manageButtons() {
button1.update();
button2.update();
button3.update();
button1.display();
button2.display();
button3.display();
}
void mousePressed() {
if (button1.press() == true) {
mode = 1;
}
if (button2.press() == true) {
mode = 2;
}
if (button3.press() == true) {
mode = 3;
}
}
void mouseReleased() {
button1.release();
button2.release();
button3.release();
}
