problem of switching character in the game

Hi,

I want to make a game which is for two players. when I press the button, the character which was chosen by 1P will move, after that if I press the button again, the character which was chosen by 2P will move, too. Just like the monopoly.

I finished the menu which is for character selection, and it can work nomarlly. The system can determine what character is for 1P and 2P.

There is a script called "Move". It is attached to every character and it can let character move after click the button. Script "Move" is successful,too. Unfortunately, it only can work normally when just one player.

So, I have a problem, The process "switch character" is failed, can someone help me to solve this?

This is my script called "DiceNumber". this script is used to create a random number and is attached to an empty game object:

 static var num:int;        // dice number (random number)
 var script:Move;         // the script attached to every character
 static var shouldMove:boolean = false;

 var savedName : String;
 var savedName1 : String;      // character’s name which is chosen by 1P
 var savedName2 : String;      // character’s name which is chosen by 2P
 
 var player:int = 2;    //how many plays
 var turn:int = 1;    // whose turn
 
 function Awake(){    
         savedName1 = PlayerPrefs.GetString("PlayerName1");   //Get character’s name chosen by 1P from character selection menu
         savedName2 = PlayerPrefs.GetString("PlayerName2");  //Get character’s name chosen by 1P from character selection menu
 }
 
 function ChangeNumber(){
         
         num=UnityEngine.Random.Range(1, 7); 
         
         shouldMove = true;
         
         script.Go();              //call Move.Go(), let character move
     }    
 
 function OnGUI(){
         if(GUI.Button(new Rect(20, 240, 50, 50), "click")){    
             turn++;                    
             ChangeNumber();
             }
         }
 
 function Update () { 
         
         if(turn>player){
         turn = 1;
         }
         for(var i=1; i<player; i++){
             if(turn==i){
             script = GameObject.Find(savedName+i).GetComponent(Move);
             }
         }
  }
