Create a master script to manage other scripts

This is from the Unity tutorials. Should be a good start...

public class UsingOtherComponents : MonoBehaviour { public GameObject otherGameObject; private AnotherScript anotherScript; private YetAnotherScript yetAnotherScript; private BoxCollider boxCol; void Awake () { anotherScript = GetComponent<AnotherScript>(); yetAnotherScript = otherGameObject.GetComponent<YetAnotherScript>(); boxCol = otherGameObject.GetComponent<BoxCollider>(); } void Start () { boxCol.size = new Vector3(3,3,3); Debug.Log("The player's score is " + anotherScript.playerScore); Debug.Log("The player has died " + yetAnotherScript.numberOfPlayerDeaths + " times"); } 

Okay, so the first things you should be aware about is that you really cant use static classes and functions in unity. That has something to do with every component on a gameobject essentially being a script the is instanced. So simply typing "using ScriptB" on the top and the calling the function like "ScriptB.Test();" really wont do anything.

What you need to do is to pass in a Script B reference as a variable in to Script A and then assign either drag it in editor or assign it via Script A. But in any case both scripts have to be in the same scene and assign to any game objects that are in that scene (they dont have to be on the same one)

So the final solution would look like this:

public class A { public B refToB; void Start() { //we call the function here refToB.Test(); } } public class B { public void Test(){ //we can do something here :) } } 

Only thing for this to work is thet you need to assign the variable refToB through the inspector panel in the editor. A simple drag and drop action.

Hope it helps :)
