Network - Change Varible Across Clients

Hello,

I have a script in my scene that controls the scoring of my game. There is only one instance of t$$anonymous$$s script, and new one IS NOT instantiated when a new player joins.

So there is always one. My question is, if the server makes a change to a variable on t$$anonymous$$s script, will all the clients receive these changes too? Automatically?

So for example, there is a variable called overallScore, in w$$anonymous$$ch the server controls. If the server changes t$$anonymous$$s value to 10, will t$$anonymous$$s value change to 10 on the client scripts too?

My understanding is that, if you have one of somet$$anonymous$$ng in the scene (t$$anonymous$$s script in t$$anonymous$$s case), and a client joins, you technically now have 2 instance of that script and so you need to sync the two together. Correct?

Example:

 if(Network.isServer){
    overallScore = 10;
 }

T$$anonymous$$s will only change the overallScore on the server side to 10, right? Whereas:

 if(Network.isServer){
    networkView.RPC("ChangeScore", RPCMode.All, 10);
 }
 
 @RPC
 function ChangeScore(new : int){
    overallScore = new;
 }

T$$anonymous$$s will be called only by the server, but apply the changes to the clients too. Right?

Do I have to do t$$anonymous$$s all the time? What if I just want to share all the variables on t$$anonymous$$s script, so its the 'centre' of the game?
