     * boxcollider 2d: make the size of the platform
     * boxcollider 2d: a second box collider that is very thin on top of the platform and isTrigger
     * (this detects collision with the player so that the method in player input works)
     * This script: change the inspector values to work for your scene, left and right bounds and speed,
     * you will need to drag the rigidbody into the inspector to move the block.
