13. Some Tips
 Start building your levels at <0,0,0>
 In project use folders
 E.g., all scene files belongs to Scenes folder
 Do not leave thing floating around at the top level
 In Hierarchy one can use an empty GameObject
like folder
 Moving that empty GameObject moves all children

14. Building the first Level
• NextLevel:
• size: 1
• Element0: level2
• If more than one level
specified, the level is
picked randomly
• GameFinished
• Check if this is
the game if
finished after
reaching this
door

15. Adding an Enemy
First we need create a
patrol route for the enemy
• A three waypoints
• Rename

• Make sure that the
waypoints (colliders)
are just fully above the
plane
Petri Lankoski

16. Adding an Enemy…
Add the enemy
• Place it near
waypoint1
• Make sure that the
enemy
(CharacterController)
