how to activate a public void from another script

how to active an:

public void blabla()

from other script?

In C#

public Transform t; //Transform that script is attached to

t.GetComponent<SCRIPT_NAME>().blabla(); //Invoke method

//or you can use

GameObject.Find("GAME_OBJECT_WITH_SCRIPT_NAME").GetComponent<SCRIPT_NAME>().blabla(); //Finding via name

//Finding via tag

GameObject.FindWithTag("GAME_OBJECT_WITH_SCRIPT_TAG").GetComponent<SCRIPT_NAME>().blabla();

Hope that helps
