Space

Doesn't do much. Just some bodies flying around in the void.

Examples

Kinda stable orbit with 3 bodies

bodies.append(Body(p=(0, 300), v=(3, 0), r=5, c=white))
bodies.append(Body(p=(0 + 150, 200), v=(3, 0), r=5, c=white))
bodies.append(Body(p=(0, 0), r=75))

Not really stable orbit with 2 bodies

bodies.append(Body(p=(100, - 100), v=(3, 2), r=25, c=white))
bodies.append(Body(p=(0, 0), r=50))

2 bodies on collision course

bodies.append(Body(p=(-600, 0), r=50, v=(3, 0)))
bodies.append(Body(p=(600, 0), r=50, v=(-3, 0)))

Create any amount of random bodies defined in count. (Don't recommend more than 50)

count = 10

rand = random.choices(population=[["5"], ["10"], ["15"], ["20"], ["30"]],
                      weights=[0.35, 0.30, 0.20, 0.1, 0.05],
                      k=count)

for x in range(count):
    bodies.append(Body(p=(random.randint(-res_x / 2, res_x / 2),
                          random.randint(-res_y / 2, res_y / 2)),
                       v=(random.randint(-5, 5),
                          random.randint(-5, 5)),
                       r=int(int(''.join(rand[x]))),
                       c=white))

You can paste these into the reset function.
