Title: Changing Font at runtime
Post by: Tripwire on January 23, 2013, 05:08:23 AM
HI,

I'm having a problem with changing the font at runtime. I have a bold orange font and a white light font which need to be changed at runtime on a click event. What i have now:
  1. public var orangeBoldFont : UIFont;
  2. public var whiteLightFont : UITFont;
  3.  
  4. private var tabFont : UILabel;
  5.  
  6. function Awake()
  7. {
  8.     tabFont = GameObject.Find("Tab01").GetComponent(UILabel);
  9.     tabFont.font = whiteLightFont;
  10. }
  11.  
  12. function OnClick()
  13. {
  14.     tabFont.font = OrangeBoldFont;
  15. }
  16.  

Now this works but only for a moment and it changes back to the original whiteLightFont :(

GameObject.Find is a really bad idea in general, and is not guaranteed to work in Awake. Start() is a better option if you must use it, but I recommend making a public var myLabel : UILabel instead. You can then set it in the inspector via drag & drop.

That said, I don't see why it would change back to white font. Perhaps you're changing it elsewhere?

Thx for your reply! I fixed the problem, made a typo somewhere ^^. No i have another question, i've always used Awake() to find stuff and never had problems with it. Why is it bad to use GameObject.Find() in Awake() function? I thought Awake and Start where both called once but Awake is called first?

Awake is called right after the object's constructor, and can be called prior to you setting up the parent and other stuff.

Consider this:
  1. GameObject go = new GameObject("Test");
  2. CustomScript cs = go.AddComponent<CustomScript>();
  3. cs.targetLabel = myLabel;
The CustomScript's Awake() function will be called prior to cs.targetLabel being set.
