Hello, I have readed a lot of forums about this, and lots of answers, but I can not still solve this problem. When I have 1 door in my scene, everything is OK, but when I add another one, I am getting NullReferenceException:
My code:
using UnityEngine;
using System.Collections;
public class Door : MonoBehaviour {
public GameObject doorBody;
GameObject useText;
Transform player;
private AudioSource doorSound;
public float doorOpenAngle = 90.0f;
public float doorCloseAngle = 0.0f;
public float doorAnimSpeed = 2.0f;
private Quaternion doorOpen = Quaternion.identity;
private Quaternion doorClose = Quaternion.identity;
private Transform playerTrans = null;
public bool doorStatus = false; //false = close, true = open
private bool doorGo = false;
void Start()
{
doorStatus = false; //door is open
doorSound = GetComponent();
doorOpen = Quaternion.Euler(0, doorOpenAngle, 0);
doorClose = Quaternion.Euler(0, doorCloseAngle, 0);
playerTrans = GameObject.FindWithTag("Player").transform;
Debug.Log(playerTrans.position);
useText = GameObject.FindWithTag("Use");
useText.SetActive(false);
}
void Update()
{
if (Vector3.Distance(playerTrans.position, this.transform.position) < 2f)
{
useText.SetActive(true);
if (Input.GetKeyDown(KeyCode.E) && !doorGo)
{
doorBody.GetComponent().enabled = false;
doorSound.mute = false;
if (doorStatus)
{ //close door
StartCoroutine(this.moveDoor(doorClose));
doorSound.Play();
}
else { //open door
StartCoroutine(this.moveDoor(doorOpen));
doorSound.Play();
}
}
} else
{
useText.SetActive(false);
}
}
public IEnumerator moveDoor(Quaternion dest)
{
doorGo = true;
while (Quaternion.Angle(transform.localRotation, dest) > 4.0f)
{
transform.localRotation = Quaternion.Slerp(transform.localRotation, dest, Time.deltaTime * doorAnimSpeed);
yield return null;
}
//Change door status
doorBody.GetComponent().enabled = true;
doorStatus = !doorStatus;
doorGo = false;
yield return null;
}
}
