Question

Help needed in python ! Classes can not be used ! Thanx

Many games have complex physics engines, and one major function of these engines is to figure out f two objects are colliding. Weirdly-shaped objects are often approximated as balls. In this problem, we will figure out if two balls are colliding. You will need to remember how to unpack tuples For calculating collision, we only care about a ball's position in space, as well as its size. We can store a ball's position with the (x, y, z) coordinates of its center point, and we can calculate its size if we know its radius. Thus, we will represent a ball in 3D space as a tuple of (x, y, z, r) Program Specifications: Write a function ball_collide(b1, b2) that takes two balls as parameters and computes if they are colliding. Your function can only accept 2 parameters and must use tuple unpacking . The parameters will be passed in the format (x, y, z, r) .Your function should return a Boolean saying whether or not the balls are colliding If run as an independent program: Shall open test file located at /home/tests/Balltest.txt o Test cases are in the format x1,y1,z1.r1:x2,y2,z2,12 o 1,2,3,4:5,6,7,8 Shall output the test case and the result of the test

Answer 1

def ball_collide(b1, b2):
        (x1, y1, z1, r1) = b1
        (x2, y2, z2, r2) = b2
        
        dis = ((x1 - x2) ** 2 + (y1 - y2) ** 2 + (z1 - z2) ** 2) ** 0.5
        return dis < (r1 + r2)
        
fileName = 'tests.txt'
for l in open(fileName).readlines():
    b1, b2 = l.split(':')
    b1 = [int(x) for x in b1.split(',')]
    b2 = [int(x) for x in b2.split(',')]
    
    print('Test:', l, ' => ', ball_collide(tuple(b1), tuple(b2)))
