Trampoline and brick

A trampoline differs from a bouncy ball because the former makes things that collide with it bounce instead of itself bouncing. Unity doesn't do this automatically for us, So, we need to use scripting.

Feature: When a brick drops from mid-air onto a trampoline, it bounces up, diminished by gravity.

Build the scene and turn the target into a trampoline, as follows:

1. Navigate to File | Save Scene As and name it BrickTrampoline.

2. Delete the BallGame script component from GameController using gear icon | Remove Component. We won't need it.

3. Rename the Target object to Trampoline.

4. Set its Position to (0, 0.2, 0).

5. To create the brick, navigate to GameObject | 3D Object | Cube and rename it to Brick.

6. Set its Scale to (0.25, 0.5, 1) and Position to (0, 5, 0).

7. Drag the Red material onto it.

8. Add a Rigidbody by navigating to Add Component | Physics | Rigidbody.

When you play now, the brick drops to a dead stop. Make a new script on trampoline, as follows:

1. With Trampoline selected in Hierarchy...
