get the gameobject's variable

Hi everyone, if in my game, i instantiated number of character and each of them have a script called "A.cs",
when my game server pass a event back and every "A.cs" will listen to the event to do something,
how can i get the character's variable?
As every character have an variable "playerid", i have to check if it equal before do something.
i do not know how to fill in the if condition.
part of script that belong to the character

 void updatecharactermovement(int playeruid,string command,float a,float b,float c){
         if(command=="move"){
                 if(playeruid=xxxxxxxxxxxxxx){
             transform.eulerAngles=new Vector3(a,b,c);
                 }
         }
         if(command=="stop"){
             if(playeruid=xxxxxxxxxxxxxx){
                 transform.position=new Vector3(a,b,c);
                 
             }
         }
         
     }

part of script that instantiate characters

 private void addnewplayertolist(int memberid,string membername,float posx,float posy,float posz,float rotx,float roty,float rotz,int animationid,int movementspeed){
         
         //check if the player already in list
         bool exist=false;
         for(int i=0;i<myneighbor.Count;i++){
             if(myneighbor[i].playerid==memberid){
                 exist=true;
                 break;
             }
         }
         if(!exist){
             PhotonService.ActorData newplayer=new PhotonService.ActorData();
             newplayer.playerid=memberid;
             newplayer.playername=membername;
             newplayer.posx=posx;
             newplayer.posy=posy;
             newplayer.posz=posz;
             newplayer.rotx=rotx;
             newplayer.roty=roty;
             newplayer.rotz=rotz;
             newplayer.animationid=animationid;
             newplayer.movementspeed=movementspeed;
             
             
             GameObject model=(GameObject)Instantiate(Resources.Load("player"),new Vector3(posx,posy,posz),Quaternion.identity);
             model.name=newplayer.playername;
             model.transform.eulerAngles=new Vector3(rotx,roty,rotz);  
             
             newplayer.playeractor=model;
             myneighbor.Add(newplayer);
             model.AddComponent("otherplayercontroler");    
         }
     }
