In this example (Figure 5-1), we use the keyboard to switch between shapes and colors. This is only a simple example. You can use the keyboard to switch between different functions controlling many things or create a switchable demo of all examples in this book. As a final example for “backstaging,” let’s make a sketch that uses the keyboard to reset.

Figure 5-1 Example of how we can reset the canvas after drawing frame over frame

USE THE KEYBOARD TO RESET THE VISUAL OUTPUT

void setup() {

size(400, 400);

background(0); noStroke(); rectMode(CENTER);

}

void draw() {

fill(40 + 20 * noise(0.8 - frameCount/2000.), 155, noise(frameCount/100.) * 255, random(10, 200));

rect(width * noise(0.2 + frameCount/100.), height * noise(0.3 + frameCount/200.), 100, 100);

}

void keyPressed(){

background(0);

}
