of the arena object is less than or equal to 0, it adds the kill value of the arena
object to the total kill value. The arena object is destroyed by setting the
active status to false and the visible status to false.

3. The total kill value that equals the total of all the kill values of the destroyed

arena objects that have just been destroyed by a collision with the input
object Obj is returned.
