this is my full script using UnityEngine; using System.Collections.Generic; using UnityEngine.UI ;
public class interact : MonoBehaviour { public string interactbutton;
public float interactdistance = 3f;
public LayerMask interactlayer; // filter
public Image interacticon; // picture to show interaction
public bool isinteracting;
// Use this for initialization
void Start () {
//set interact icon to be invisible
if (interacticon != null)
{
interacticon.enabled = false;
}
}
// Update is called once per frame
void Update ()
{
Ray ray = new Ray (transform.position, transform.forward);
RaycastHit hit;
//shot a ray
if (Physics.Raycast (ray, out hit, interactdistance, interactlayer))
{
//check if we are not interacting
if (isinteracting == false)
{
interacticon.enabled = true;
// if we press the interaction button
if (Input.GetButtonDown (interactbutton))
{
// if it is a door
if (hit.collider.CompareTag ("Door"))
{
//open the door
hit.collider.GetComponents<Door>().ChangeDoorState();
}
}
}
}
else
{
interacticon.enabled = false;
}
}
}

In this line:
hit.collider.GetComponents<Door>().ChangeDoorState();
You use the GetComponents command, which returns an array of all found Components of the specified Type. Keeping this in mind, the error message tells you exactly what you need to know: The array of Type Door[] itself doesn't have a function "ChangeDoorState". Only the Type "Door" has this, so you have to first access one of the array's elements, like this:
hit.collider.GetComponents<Door>()[0].ChangeDoorState();
However, since I assume that no collider will have more than one Door script on it, it's probably better to use the GetComponent command:
hit.collider.GetComponent<Door>().ChangeDoorState();
