Time for action – Replicating a variable

Let's keep working with AwesomeWeaponUpgrade, and add in some variable replication.

1. First let's add a new variable to the class:

   var int TestInt;

2. Now let's write the replication block. We've already discussed bNetDirty, which we'll be using here. If any replicated property is changed, bNetDirty will be set to true. We need to let the game know that our variable needs to be replicated in that case.

   replication
   {
       if(bNetDirty)
           TestInt;
   }

3. Now for PostBeginPlay. We'll leave it as simulated, but we'll call different functions for the client and the server.

   simulated function PostBeginPlay()
   {
       if(Role == ROLE_Authority)
           SetTimer(1.0, true, 'ServerTest');
       else
           SetTimer(1.0, true, 'ClientTest');
   }

4. Now for ServerTest :

   function ServerTest()
   {
       TestInt++;
       `log("ServerTest:" @ TestInt);
   }

5. And ClientTest :

   simulated function ClientTest()
   {
       `log("ClientTest:" @ TestInt);
   }

6. Now compile the code.

7. ServerTest will only be called...
