How to pass variables in a Network using RPC function(s)

This should be an easy question to anyone who tried to make a Multiplayer game;

Please, can anyone tell me in a clear way how to use RPC functions?

From what I understood about it, the RPC function works like this;

 using UnityEngine;
 using System.Collections;
 
 public class ExampleRPC : MonoBehaviour {
 
     int number = 120; //the number I want to send to another machine using RPC.
     public static bool somethingHappens = false;
 
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
         if(somethingHappens){ //If anything happens that makes this variable true:
             networkView.RPC("CallThisFunctionWithRPC", RPCMode.All, number); //Send the variable to anything that has a "CallThisFunctionWithRPC" function(?)
         }
     }
 
     [RPC] void CallThisFunctionWithRPC(int newNumber){ //The function
           //And here? How do I tell in this function to make the "number" of the old machine become the "number" of the new machine?
           number = newNumber; //(?)
     }
 }

I already tried doing this and it didn't work, the variable was 120 all the time even if I changed it ingame, the 2 variables on the 2 different builds were not synchronyzed.

That's because the int "number" is a private int only for ExampleRPC. I'm guessing that when you change it inGame you change a differnt private int in a different class.

The RPC setup is fine.

Yes, actually I succesfully synchronized the 2 variables by adding a few lines of code:

 using UnityEngine;
 using System.Collections;
 
 public class ExampleRPC : $$anonymous$$onoBehaviour {
 
     int number = 120;
     public static bool somethingHappens = false;
 
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
         if(somethingHappens){
             number = 300;
         }
 
         if(Network.isServer){
             networkView.RPC("CallThisFunctionWithRPC", RPC$$anonymous$$ode.All, number);
         }
 
         if(Network.isClient){
             CallThisFunctionWithRPC(number);
         }
     }
 
     [RPC] void CallThisFunctionWithRPC(int newNumber){
         number = newNumber;
     }
 }

$$anonymous$$aybe calling the RPC function every frame is not the best solution, but it works for me, thank you for answering my question even if you didn't really help me.
