Script Reference in Unity

Question

I'm creating a game that have multiples references to scripts, one to another.

For exemple:

1. Controller script
2. SomeBehavior script
3. GUI script

My doubt enter when I can do two different things:

1. In SomeBehavior access/edit GUI variable/function that I whant... Like:
   
   1.1. variable = GameObject.Find("GuiTag").GetComponent< GUI script >();
   variable.score.... and go on...
   
   
2. In SomeBehavior access/edit GUI variable/function by Controller.gui (gui a public variable on controller script)... Centralization all the base scripts to one, in that way, having less variables in the scripts, less memory (perraps)...
   
   2.1. variable = GameObject.Find("ControllerTag").GetComponent< Controller script >();
   variable.gui.score....
   
   

Which one is better?

Answer 1

In the Scripts that you will only have one of you can set a public static variable in that class with a public get and private set. On the Start or Awake function you set that variable to this and then you can access that script easily from any other scripts.
