How to have a function in a script available to be called from all the project?

Questions & Answers

As i saw as reponse for a question somewhere here, i use this in order to have variables used in all the project.

public static class GlobalVariables{
   	public static string myVariable
}

And i use it from anywhere in my project in this way:

GlobalVariables.myVariable = "something";

My question is: can i use in some way like this for call functions from any script?

Thanks in advance.

Hello there,

Just like a static variable can be accessed from another script, so can a function. It’s very common for Util classes to have lots of static functions that can be called from anywhere.

Here is an example from my Utils class:

public class Utils : MonoBehaviour
{

    public static int GenerateRandXDigitCode(int nbOfDigits)
    {
        string toReturn = "";
        for (int i = 0; i < nbOfDigits; ++i)
        {
            int rand = UnityEngine.Random.Range(1, 10);
            toReturn += rand.ToString();
        }

        return int.Parse(toReturn);
    }

}

You can call this function from pretty much anywhere (assuming there are no namespaces involved) with the following line:

int myInt = Utils.GenerateRandXDigitCode(4);

Note: My class derives from Monobehaviour because of some other code I do in there, but yours doesn’t necessarily need to.

I hope that helps!
