yield WaitForSeconds (5);
guiText.enabled = false;
}
Why?
These are literally copied and pasted with the specifics of what the text says
and how long to display it altered. Again, what we have here are a lot of
instructions waiting for the nod to fire. Note that we also haven't created
the triggers for the StayOutofWaterHint and TryEMPHint. That will come.
Step 15:
Save, return to Unity, and check for syntax errors in the Console.
Fix if needed.
Step 16:
Attach this script to the GUITextHints GameObject. Remember
this is done by just dragging the script from the Project panel to the
GameObject in the Hierarchy.
Scripting Triggers
It's all fairly anticlimactic at this point. This script is attached to the
object it needs to be and is all set to start displaying and changing text,
but nobody's told it to do so yet. With this next script we will add real
functionality to the trigger created earlier and instruct it to start firing
functions created in the first script.
Step 17:
In your Project panel, select the Scripts folder. Create a new
JavaScript and name it
EntryWayTextTriggerScript
. Open it by
double-clicking it.
Step 18:
Delete the default code and enter the following:
private var guiTextObject : GameObject;
Why?
This script we are writing here will be attached to the triggers. But this
script needs to talk to another script attached to another GameObject.
The other GameObject is GUITextHints, which we're going to call
guiTextObject here.
Step 19:
Add the following to define the new variable:
private var guiTextObject : GameObject;
function Awake () {
guiTextObject = GameObject.Find(“GUITextHints”);
}
Why?
Similar to the last chapter, this function Awake runs at the start of the
game and goes out and finds the object GUITextHints and defines that as
guiTextObject within this code.
