how to find direction of two rigid bodies after collide them with each other

the main thing about i m confused is to find the new direction of ball after collision. can the ball direction is handled by unity itself?????? thanks for your reply.....

You can move objects around in Unity in 2 ways. You can either manually control the movement or use the built in physics. In many cases you will want to use the physics in Unity to handle the behavior of your moving objects. In these cases, ins$$anonymous$$d of moving and tracking things, you simply apply forces and let Unity handle the rest. So in your case you would apply a force to swing the bat and then the physics would take over. $$anonymous$$eep in $$anonymous$$d that everything should have a rigidbody and a collider attached. Objects with non-kinematic rigidbodies will use physics to move around and bump into things. You move these around by applying forces. Objects with kinematic rigidbodies will still bump into things but will never be affected by another object. You move these around by changing the position directly. You might also set your bat as non-kinematic and move it's position directly but you still want the ball to be set to non-kinematic. That way you don't really need any code for the ball as it will simply react to other moving objects.
