    raise ValueError(f"empty range in randrange({start}, {stop})")
ValueError: empty range in randrange(1, 1)

Steps to reproduce

1. Create a big planet
2. Create a small planet far from the big one (try to make the click as short as possible)

Possible Solutions

Solution 1

in planet.update(), replace:

            particles.append(
                Particle(
                    self.x,
                    self.y,
                    [np.subtract(self.color, (35, 35, 35))],
                    1,
                    int(-self.velocity[0]),
                    1,
                    int(-self.velocity[1]),
                    1,
                    int(self.radius / 1.5),
                    0.4,
                    0,
                )
            )

with

            particles.append(
                Particle(
                    self.x,
                    self.y,
                    [np.subtract(self.color, (35, 35, 35))],
                    1,
                    int(-self.velocity[0]),
                    1,
                    int(-self.velocity[1]),
                    1,
                    max(1, int(self.radius / 1.5)),
                    0.4,
                    0,
                )
            )

Solution 2

in particle.__init__(), replace:

self.radius = random.randint(min_radius, max_radius)

with

self.radius = random.randint(min(min_radius, max_radius), max(min_radius, max_radius))
