Prefabs calling functions

[ArmarageX]

Helloz…

I have a question about Optimisation / Performance for mobile device…
I have alot of prefabs being instantiated into the game, (for mobile, its not ideal… i know)
In the game, i have an Empty game object that has a script that holds many FUNCTIONS…

Being a prefab, i cannot CACHE anything that is IN the game…into a variable via the editor

Id like the prefabs to locate that empty gameObject… and call on the function

Ive tried:

1. GameObject.Find that
   object…GetComponent(Script)… and
   then Script.Function().
2. GameObject.Find… and Send Message
3. GameObjectFindByTag (apparently
   faster)
4. Find it via a static
   variable: Script.StaticVariable.Function()
5. Hierarchy it to a parent…
   Transform.parent.GetComponent(Script).Function

Hope im making sense >.<

Would like to ask what is the fastest method for an Instanced Prefab to call upon a function being held by an Empty Game Object.
And if it theres other methods than the ones i have listed, then i dont know them And would like your wisdom!!

Thanks!!

Your 4th option: Find it via a static variable: Script.StaticVariable.Function() is what we call a singleton design.

Example

public class Processor: MonoBehaviour
{
    private static Processorinstance;
 
    void Awake() 
    {
       if (instance != null && instance != this) 
       {
         Destroy( this.gameObject );
         return;
       } 
       else 
       {
         instance = this;
       }
    }
 
    public static Processor GetInstance() 
    {
       return instance;
    }

    public Vector3 NormalFunction( Vector3 a ) {
       ...
    }
}

By using static variables and functions, you can refer to the Processor from any script without any Find() or variable-assignment.

You can just use it as:

Processor.GetInstance().NormalFunction( ... );

I am quite sure that this (static variable) is the fastest among the 5 options. (If anyone’s opinion differs from mine, feel free to enlighten me)
