background() placed in void setup() or void draw() ? does it matter?

in Programming Questions • 1 year ago

Well, as I was reading through some references.

If you read the

setup() .. it says you can initialize like the background color etc

BUT if you go to the background() reference.. it says to place it in the draw()

now, it says it clears it out every time?

what does that mean? isnt clear?

I know I sound like a noob here lol but I appreciate the help :D

Question: does it matter where it goes? is there a difference?

Best Regards, El_Emperador

easiest way to understand this is to write your own program to see the difference. run this once with the background call in setup and once with it in draw() and you will see the meaning

int x = 0;
void setup(){
size(640, 480);
// background(0);// uncomment and run it here once
fill(255);
}
void draw(){
// background(0); //uncomment and run it here to see the difference
rect(x, 300, 50,50);
x+=5;
}

Insentien..

Yes it does. If you put background() in setup(), your background will be set only once (when you start the program). If you put background() in draw(), your background will be refreshed every frame.

AHH I see,

so it depends how you want to use it, sometimes those circles can create like a worm if you put it in the setup :P
