Raycasts not changing direction when using transform.lookAt()

Question

Hi, so Im changing enemys direction with transform.lookat, and I use raycasts to see if player hit raycast. However when for some reason raycasts direction not changes when I do transform.lookAt();

Code:

 //Creates Raycasts
 Ray see1 = new Ray();
         Ray see2 = new Ray();
         Ray see3 = new Ray();
 
 //Raycasts position
         see1.origin = new Vector3(transform.position.x - 0.1f, transform.position.y, transform.position.z);
         see2.origin = transform.position;
         see3.origin = new Vector3(transform.position.x + 0.1f, transform.position.y, transform.position.z);
 
 //Raycasts direction
         see1.direction = Vector3.forward;
         see2.direction = Vector3.forward;
         see3.direction = Vector3.forward;
 
 //For Debug
         Debug.DrawRay(see2.origin, see2.direction, new Color(255, 0, 0), 1000000f);
 
         if (states == theState.patrol)
         {
                 agent.destination = randomizeA;
                 transform.LookAt(new Vector3(randomizeA.x, transform.position.y, randomizeA.z));
 
             }

Your problem is probably with the declaration of the raycast direction: you're using Vector3.forward which is in global space, while you want to shoot while taking the object's own rotation into account, which means local space.

What you want to do is set the raycast direction to the transform.forward value, which is the direction the object itself is facing after calculating its (and its parents's) rotations, such as after your .LookAt() call.
