Hi @Rafsing
I think the main Processing 3.0 issue here is you can’ t use variables as arguments for size()
on setup()
anymore. Have a look at: https://processing.org/reference/settings_.html
But then, using `surface’ for everything it works for me:
void setup() {
surface.setResizable(true);
surface.setSize(displayWidth, displayHeight) ;
surface.setLocation(0, 0);
}
void draw() {
background(255, 0, 0);
ellipse(width/2, height/2, 100, 50);
}
