instantiate spawning meany objects in multiplayer

hey iam using appwarp for multiplayer and i have a player asset which i want to instantiate on the network.iam using the sample script that came with it and it just creates a primitive capsule.but when i change it to resources. load,it instantiates loads of copies of the player continuously even though the function is supposed to work only once.please help

original code snippet :

 void Start () {
         
         addPlayer();
     }
     
     public float interval = 0.1f;
     float timer = 0;
 
     
     public static GameObject obj;
     
     public static void addPlayer()
     {
         obj = GameObject.CreatePrimitive(PrimitiveType.Capsule);
         obj.transform.position = new Vector3(732f,1.5f,500f);
     }

modified code using Resources.load: void Start () {

         addPlayer();
     }
     
     public float interval = 0.1f;
     float timer = 0;
 
     
     public static GameObject obj;
     
     public static void addPlayer()
     {
         obj = Instantiate(Resources.Load("Player", typeof(GameObject))) as GameObject;
         obj.transform.position = new Vector3(732f,1.5f,500f);
     }
         

Please help!
