7. Observe that as you click on the populated references inside Level2Ex-
tras , Unity highlights the GameObject instances with a unique yellow border
so that you can quickly find the actual object instances that are connected in
the hierarchy.
8. Now that Level2Extras has been properly configured, create another
script named Level2Init , and add an instance of it to the _level2
GameObject.
9. The level2Init script will use the Level2Extras script as an interface to
find specific GameObjects and connect them into the appropriate level 2 pop
ups. This needs to happen since the pop ups are global; they cannot pre-
serve references to objects that are dynamically loaded from later levels.
10. In the start() method of Level2Init , the script attempts to locate the
Player GameObject, named as either Player or Player1 :
GameObject playerObj = GameObject.Find
("Player1");
if (playerObj == null)
playerObj = GameObject.Find ("Player");
