//Attach this script to a GameObject. Make sure it has a Collider component by clicking the Add Component button. Then click Physics>Box Collider to attach a Box Collider component. //This script creates a BoxCast in front of the GameObject and outputs a message if another Collider is hit with the Collider’s name. //It also draws where the ray and BoxCast extends to. Just press the Gizmos button to see it in Play Mode. //Make sure to have another GameObject with a Collider component for the BoxCast to collide with.
