[bug] Can't check for collisions or overlaps between groups

[quinton-ashley]

My documentation has always stated that checking collisions or overlaps between groups works, but it seems I forgot to implement this?! I checked past versions of p5play to see if this was a regression but it's not. 👀

Probably the most long standing bug in p5play. No one ever reported it either... can't believe it.

Top priority to fix!!

new Q5();

new Canvas(400, 400);

let a0 = new Group();
let s0 = new Sprite(100, 100, 50, 50);

let b0 = new Group();
let s1 = new Sprite(300, 300);

a0.add(s0);
b0.add(s1);

a0.overlapping(b0, () => log('hit'));

function draw() {
	if (mouse.pressing()) s0.moveTowards(mouse);
	else s0.speed = 0;

	if (a0.overlapping(b0)) {
		s0.color = 'orange';
	} else {
		s0.color = 'green';
	}

	if (b0.overlapping(a0)) {
		s1.color = 'yellow';
	} else {
		s1.color = 'green';
	}

	if (kb.presses('g')) {
		log('g pressed');
		a0.remove(s0);
		// b1.remove(s1);
	}

	if (kb.presses('a')) {
		log('a pressed');
		a0.add(s0);
		// b1.add(s1);
	}
}
