Hi I'm currently working on my first project in pico-8 and I loosely followed a tutorial on collision detection and I wrote this function

function colliderect(x1,y1,w1,h1,x2,y2,w2,h2)
	xs = w1/2 + w2/2
	ys = h1/2 + h2/2
	xd = sqrt((x1)^2+(x2)^2)
	yd = sqrt((y1)^2+(y2)^2)
	if ((xs > xd and ys > yd)) then
		return false //colliding
	else
		return true //not colliding
	end
end

which takes the x and y coordinates and the width and height of two objects and calculates if they collide. The function itself seems to work as it should and gives the correct result when manually inputting the data but when I implement it like this

function update_player()
	for i in all(bullets) do
		if (not colliderect(player.x,player.y,player.w,player.h,i.x,i.y,i.w,i.h)) then
			sfx(1)	
		end
	end			
end

it doesn't work anymore. Even if I am standing right on the bullet it doesn't play the sound it should when colliding (and yes I did check if it's the right SFX). I am also not getting any errors when running the program so I don't really know what's wrong. Any help would be very much appreciated.
