     public class PlayerController : NetworkBehaviour
     {
         public NetworkVariable<int> playerScore = new NetworkVariable<int>();

         // Score updating method
         public void AddScore(int points)
         {
             if (IsServer)
             {
                 playerScore.Value += points;
             }
         }
     }

This ensures that player scores are updated and synchronized across all clients.
