Question by shaaafeee · May 02, 2020 at 06:10 PM · physicsrigidbodyforcemove an object

Bouncing an object from A to B

Object A will instantiate a ball and shoot it upward. What I want to achieve then is bounce the ball once it hits the Object as outlined in the image below. The player will be moving the Object from left to right, the goal is to move the ball from A to B without hitting the floor. How do I achieve this? Am I supposed to calculate the trajectory angle or I can achieve this using Vector3 reflection? For further reference; https://www.youtube.com/watch?v=L5ywbODRVy8&t=161s alt text

Hello!

I watched the video you linked and have a pretty good idea of what you want to achieve. I would approach this by adding a Rigidbody2D and CircleCollider2D component to the instantiated ball, applying force to the ball to 'launch' it, and then having the red object have a PhysicsMaterial2D (along with its own Rigidbody2D and Collider2D) on it with the desired bounce amount.

After that, it's a matter of having a trigger collider on point B to check for the collision.

It seems to be working as expected. It's so convenient when Physics Material 2D does its own job. Thanks a lot. Now I got to play around with the Trigger collider after it reaches Point B.
