Mission Two – Testing a Player's Learning - Creating E-Learning Games with Unity - page 193

public int numEntries;
public npcCondition data;
26. Drag-and-drop listData from the LevelLogicObj GameObject to the
data field on condition_listFull .
27. Inside the implementation of eval() , condition_isFull does its work.
If data is not null, it extracts the number of entries from the listData's list
through its count member as shown in the following code:
if (data != null)
{
int count = (data as
listData)._listData.Count;
28. If the count of the listData component's list array equals the numEntries
value on this script, the return value is set to true . Otherwise, it remains
false as shown in the following code snippet:
if (count == numEntries)
rval = true;
29. Now that condition_listFull is complete, let's create the response
that will occur when the list is found to be true— re-
sponse_ShowRaceResultsPopup . This script will check the status of the
mission, and enable the correct pop up on the main camera to achieve the
desired gameflow.
30. Create a new script named response_ShowRaceResultsPopup , change
its base class to npcResponse , and add an instance of it to LevelLo-
gicObj .
31. Add the following five public member variables to this script:
• An npcCondition named data
• A GameObject named player
• A gameMgr named gm
• A GameObject named passPopup
• A GameObject named retryPopup
