Time for action – Checking the level's NetMode.

   simulated function PostBeginPlay()
   {
       `log("PostBeginPlay====================");
       `log("NetMode:" @ WorldInfo.NetMode);
   }

2. Compile the code.

3. Now run the server and client. Let's see what shows up in the server's log:

   [0019.97] ScriptLog: PostBeginPlay====================
   [0019.97] ScriptLog: NetMode: NM_DedicatedServer

4. And now for the client:

   [0013.26] ScriptLog: PostBeginPlay====================
   [0013.26] ScriptLog: NetMode: NM_Client
