Aim:
Write a function ball_collide that takes two balls as parameters and computes if they are colliding. Your function should return a Boolean representing whether or not the balls are colliding.
Hint: Represent a ball on a plane as a tuple of (x, y, r), r being the radius If (distance between two balls centers) <= (sum of their radii) then (they are colliding)
Program:
import math
def ball_collide(x1,y1,r1,x2,y2,r2):
dist=math.sqrt((x2-x1)**2+(y2-y1)**2);
print("Distance b/w two balls:",dist)
center=dist/2;
print("Collision point",center);
r=r1+r2;
print("Sum of radious",r)
if(center<=r):
print("They are Colliding")
return True;
else:
print("Not Colliding")
return False;
c=ball_collide(4,4,3,2,2,3)
print(c)
c=ball_collide(100,200,20,200,100,10)
print(c)
Execution:
Distance b/w two balls: 2.8284271247461903 Collision point 1.4142135623730951 Sum of radious 6 They are Colliding True Distance b/w two balls: 141.4213562373095 Collision point 70.71067811865476 Sum of radious 30 Not Colliding False
