Raycast rotating with object rotating

Hello everybody, i have a moving and rotating object that shoots out raycasts to see if there is any obstacle in a specific direction. The problem is that with my current code, the raycasts don't rotate. Does anybody know how to fix this?

Code:

 var rightray = new Ray  (transform.position, Vector3.right); // shoots ray right even though it says left
 var hitright : RaycastHit; // hit information
 
 if(Physics.Raycast (rightray, hitright, obstacleavoidancerangeside)){if (hitright.transform.tag == "metal"){obstaclerightofyou = true;{AvoidObstacleRight();}} // If raycast hits something within o avoid obstacle
 else obstaclerightofyou = false; } 
 var forwray = new Ray (transform.position, Vector3.forward); //Shoots ray in front of object
             var hitforw : RaycastHit; // hit information
            if (Physics.Raycast (forwray, hitforw, obstacleavoidancerange)){ if (hitforw.transform.tag == "metal"){obstacleinfrontofyou = true;{AvoidObstacleForward();}} // If raycast hits something within o avoid obstacle
            else obstacleinfrontofyou = false;
            }
            
 var leftray = new Ray (transform.position, Vector3.left); //shoots ray left even though it says right
             var hitleft : RaycastHit; // hit information
            if (Physics.Raycast (leftray, hitleft, obstacleavoidancerangeside)){ if (hitleft.transform.tag == "metal"){obstacleleftofyou = true;{AvoidObstacleLeft();}} // If raycast hits something within o avoid obstacle
            else obstacleleftofyou = false;
            }
            }
            
 function AvoidObstacleRight (){
 Debug.Log("obstacleright");
 }
 
 function AvoidObstacleLeft(){
 Debug.Log("obstacle left");
 }
 
 function AvoidObstacleForward (){
 Debug.Log("obstacle in front");
 }
