Methods Repeats for each New Player connected

Hi! I'm working on multiplayer rpg game and i have a functions: Aggro, Attack... For example function Attack is called when T pressed and then damage is being given. Method finished. Then, when we create a new player and having entered the world, this function is called for a new player again. And i dont need to do. And when monster made Aggro() on the player was standing near this monster,a new clients will see how this monster made Aggro on this player again and the texture that show AggroTexture will appear again, but i need this new player see the result when aggro is finished. So there are methods which repeat for new players even if they finished long ago.

Example of Attack() Function:

     void Attack()
     {
         if (_target != null && IfTargetAlive())
         {
             if (_targetSelected && _target != null && networkView.isMine && IfTargetAlive() && _target.tag == "Creature" ||
                 (this.tag != _target.tag && _target.tag.Contains("Player")))
             {
                 if (Vector3.Distance(_target.transform.position, this.transform.position) <= 1.6f &&
                     Mathf.Abs(Vector3.Angle(transform.forward, this.transform.position - _target.transform.position)) < 270)
                 {
                     attackable = true;
 
                     if (canAttack)
                     {
                         if (Input.GetKey(KeyCode.T))
                         {
                             animMainFlag = true;
                         }
 
                         if (animMainFlag)
                         {
                             if (!animChoosen)
                             {
                                 curAnimNum = (int)Random.Range(0, 3);
                                 animChoosen = true;
                             }
 
                             if (animChoosen)
                             {
                                 networkView.RPC("AnimNetwork", RPCMode.AllBuffered, animationAttackList.ElementAt(curAnimNum));
                             }
                         }
                     }
 
                     else
                     {
                         attackable = false;
                     }
                 }
             }
         }
     }
