Changing SKPhysicsBody parameters doesn't have effect

Question

I try to simulate behavior of different types of balls (football ball, tennis, golf, volleyball etc). For these purposes I tried to change density, mass, size parameters of the physics body. In my game it doesn't have effect and I tried to simulate it in very simple app consists from ball and paddle

the ball always rises to the same height with the same speed regardless of mass, density, size

Is this because of restitution equals 1? How can I simulate behavior of different ball types in this way?

Answer 1

you need to change the restitution property as well as the Lin. Dampening and Ang. Dampening per ball

for my example i have

tennis ball - rest 0.6 lin 0.2 ang 0.2

soccer ball - rest. 0.5 lin 0.3 ang 0.2

golf ball - rest 0.8 lin 0.3 ang 0.3

shot put - rest 0.1 lin 0.1 ang 0.1

here is a link to the Apple definitions of the properties
