10. Next, add the Rocket script that we created by dragging the script to the rocket
object in the Hierarchy .
11. Then, go to the object's Inspector view to add the Box Collider to the rocket object
by going to Component | Physics | Box Collider .
When we add the Box Collider to the new object, the Box Collider will
automaically adjust its size to it around the object. This is why we
don't have to set up the size or the posiion of the Box Collider .
12. Then, we go to the Inspector view and set the following:
Transform
Position : X: 0 , Y: 0 , Z: 0
