Change sketch size according to content (non-dynamic)

in Programming Questions • 2 years ago

Hi there,

this is a simplification of a longer and more complex code I'm working on...

let's say I have a rectangle with random size and I want to change the size of the sketch so that it equals the width of the rectangle + 10.

How do I do that?

The problem:

void setup() {
size(300,300);
background(255);
int recw = int(random(250,800));
rect(10,10, recw, recw);
width = recw+10;
height = recw+10;
}
void draw() {
}

If you just need to set it when you first run it this should work:

int recw = int(random(250,800));
void setup() {
size(recw+10,recw+10);
background(255);
}
void draw() {
rect(5, 5, recw, recw);
}

Although size() should be the first call in setup(), you can define variables first and use them in setup().

Actually (for some boring reasons) I'd like to do this in the setup after some other code. I might use your suggestion if there is no other way to do this, but this would greatly affect my code logic.
