Hi I am looking to insert two simple buttons that will navigate between multiple screens. Is there an easy way to do this? I have looked at tutorials online and they seem very complicated.

Any help would be much appricated!

The trick is to have a state variable that tracks which screen you are on, have draw() draw that screen and the buttons, and then have clicking on the buttons update the state variable:

int state=0;
color c[]= {
color(255, 0, 0), color(255, 255, 0), color(0, 255, 0), color(0, 0, 255)
};
void setup() {
size(150, 150);
ellipseMode(CENTER);
stroke(0);
smooth();
}
void draw() {
background(c[state]);
fill(dist(mouseX,mouseY,20,75)<10?255:128);
ellipse(20,75,20,20);
fill(dist(mouseX,mouseY,130,75)<10?255:128);
ellipse(130,75,20,20);
}
void mousePressed(){
if(dist(mouseX,mouseY,20,75)<10){
state--;
}
if(dist(mouseX,mouseY,130,75)<10){
state++;
}
state+=4;
state%=4;
}
