Interactive Objects and MissionMgr - Creating E-Learning Games with Unity - page 53

Putting it all together
Now that we have developed the classes necessary for the InventoryMgr , Mis-
sionMgr , and InteractiveObj systems, let's build a scene that illustrates their
functionality.
1. To get started, let's continue from Chapter 1 , Introduction to E-Learning and
the Three Cs of 3D Games , where we left off. Load the scene and save a copy
named chapter2 .
2. Add an instance of InventoryMgr to the Player GameObject by dragging-
and-dropping it from the Project tab to the player object. Alternatively, click
on Player and select Add component from the Inspector pane. Type in the
name InventoryMgr and then click on it to add an instance.
3. Click on Player and ensure that the Tag is set to Player . The Interact-
iveObj class will use this to make sure they can only be picked up by the
player.
4. Set Height and Width to 40 pixels to make the individual cells square shaped.
Set the Yposition to 0.85 to indicate a y coordinate of 85 percent from the top
of the screen.
5. Create a new empty GameObject and name it MissionMgr . Attach the Mis-
sionMgr script to this object. We purposely detach this script from the player
because the lifespan of MissionMgr may differ from the player object.
The results of all the discussed settings are shown in the following screenshot:
