How i can get variable from other script

My game has changeable difficulty in the main menu and I'm wondering how I can access it from other scripts to change things like enemy damage and something like that. I've been trying to find something about it and so far, I don't quite understand how it works. Variable that i need access to is called mainMenuDifficulty.

 

You would want to make static variables.

Code (CSharp):

1. public class OptionsMenu : Monobehavior
2. {
3. public static int difficulty;
4. //Example: 1=Easy, 2=Normal, 3=Hard, etc...
5. }
6.  
7. // On your other script, to access this variable
8. public class ChangeOptions : Monobehavior
9. {
10. // Inside a function or where ever you're changing the variable
11. OptionsMenu.difficulty = // Make your change here
12. }

Kind of a brief demonstration. Hope it was helpful
