Unity Transition between animations, in this case we have a case where we need to open the door when the right mouse is clicked pointing to the door

HouseDoor.cs

using UnityEngine;
using System.Collections;
 
public class HouseDoor : MonoBehaviour {
 
    public Animation doorOpenAnimation;
    public Animation doorCloseAnimation;
 
    public bool doorOpen= false;
 
    void Update() {
        if (Input.GetMouseButtonDown(0)) {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hit;
            if (Physics.Raycast(ray, out hit)) {
                if (doorOpen == false) {
                    OpenDoor();
                }
                else if (doorOpen == true) {
                    CloseDoor();
                }
            }
        }
    }
 
    public void OpenDoor(){
        doorOpenAnimation.Play();
        doorOpen = true;
    }
 
    public void CloseDoor() {
        doorCloseAnimation.Play();
        doorOpen = false;
    }
}
