the button's action. This way, the button will instance a GameObject from this
Prefab on click.
6. Change the second action of this button to EnableOb-
ject(setupLevel2Prefab) . In a similar fashion as earlier, set the refer-
ence to setupLevel2Prefab by dragging-and-dropping it from the Project
tab directly in to the data field of the button's action. This way, the button will
instance a GameObject from the Prefab on click.
7. Change the third action to CameraLookPlayer() so that the view will track
the hero as the character moves in the world.
8. Change the last action of this button to HideGameOb-
ject(popup_Level2Start) to hide this panel while still leaving it at-
tached to the MainCamera GameObject persistent in _global .
9. Next, select the popup_Level2Finished button, and open up the Button1
hierarchy.
10. Change the first action of this button to CameraLookUp() . This will orient
the camera to a point above the player so that the subsequent pop ups will
display in a visually appealing way.
11. Change the next action of this button to LoadLevel3 (to tell GameMgr to
unload Level2 by destroying the root GameObject instance, and then load
Level3 ). Throughout this process, _global and all of its child objects will
be preserved.
12. Change the last action of this button to HideGameOb-
ject(popup_Level2Finish) . This will disable the rendering of this panel
while still leaving it attached to the MainCamera GameObject persistent in
_global .
13. Lastly, select the popup_Level2Repeat panel, and open the Button1 hier-
archy.
14. Change the first action to CameraLookUp() to point the camera towards the
sky (which makes the pop ups show up in a visually appealing way).
15. Change the next action to LoadLevel2 . This will tell the GameMgr script to
destroy the _level2 GameObject (and all of its children), and then reload
the _level2 GameObject, thereby resetting its state.
Congratulations! You have finished updating the pop ups for level 2. Let's move on
to the pop ups of level 1.
