Time for action - fixing the fall

In The Break-Up, our falling objects were larger, and they fell through a smaller vertical range. Now that there's no ground to hit and the sky's the limit, we should tweak a few lines of code in our EnemyShip Script (formerly the FallingObject Script). Double-click the EnemyShip Script and roll up your sleeves:

• Change:

  if(transform.position.y < 0)
  

• to:

  if(transform.position.y < -4)
  

This allows the enemy ship to reposition itself when it moves off the bottom edge of the screen, instead of when it hits the non-existent ground plane at y:0.

• Change:

  transform.position.y = 50;
  

• to:

  transform.position.y = 71;
  

When the EnemyShip is repositioned, cranking up its y value will start it just above the top edge of the screen.
