Opening multiple doors with raycast,

Hi!

Beginner here, so bear with me please :)

I have an almost fully working script, where I open doors with raycast, but multiple doors cause a problem. Basically the script does not understand the boolean of the opened door, which in turn means that I only can open and close the same door, and not for ex.. open two adjacent doors after one another - without it displaying the door-closing animation first.

Can someone point out the mistake I am making? Thanks in advance!

using System.Collections; using UnityEngine;

public class RayCastDoor : MonoBehaviour {

 bool guiShow = false;
 bool isOpen = false;

 public int rayLength = 2;

 void Update()
 {
     RaycastHit hit;
     Vector3 fwd = transform.TransformDirection(Vector3.forward);

     if(Physics.Raycast(transform.position, fwd, out hit, rayLength))
     {
         if (hit.collider.gameObject.tag == "door")
         {
             guiShow = true;
             {
                 if(Input.GetKeyDown("f") && isOpen == false)
                 {
                     hit.collider.gameObject.GetComponent<Animation>().Play("DoorRayOpen");
                     isOpen = true;
                     guiShow = false;
                 }

                 else if(Input.GetKeyDown("f") && isOpen == true)
                 {
                     hit.collider.gameObject.GetComponent<Animation>().Play("DoorRayClose");
                     isOpen = false;
                     guiShow = false;
                 }
             }
         }
     }
     else
     {
         guiShow = false;
     }
 }
 void OnGUI()
 {
     if(guiShow == true && isOpen == false)
     {
         GUI.Box(new Rect(Screen.width / 2, Screen.height / 2, 100, 25), "Open Door");
     }
     else if(guiShow == true && isOpen == true)
     {
         GUI.Box(new Rect(Screen.width / 2, Screen.height / 2, 100, 25), "Close Door");
     }
 }

}
