Why when getting component the variable is null ?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Teleport : MonoBehaviour {
public GameObject player;
public Camera mainCamera;
public Camera firstCam;
public Camera camera;
private List<GameObject> TeleportBooths;
private TeleportationsCore tc;
private void Start()
{
InstantiateObjects gos = GetComponent<InstantiateObjects>();
TeleportBooths = new List<GameObject>();
TeleportBooths = gos.PrefabsList();
firstCam.enabled = false;
mainCamera.enabled = false;
camera.enabled = true;
for (int i = 0; i < TeleportBooths.Count; i++)
{
TeleportBooths[i].AddComponent<TeleportationsCore>();
}
tc = GetComponent<TeleportationsCore>();
WorkingBooth();
}
private void WorkingBooth()
{
player.transform.position = TeleportBooths[tc.WorkingBooth()].transform.position;
camera.transform.position = new Vector3(TeleportBooths[tc.WorkingBooth()].transform.position.x - 10, TeleportBooths[tc.WorkingBooth()].transform.position.y + 10, TeleportBooths[tc.WorkingBooth()].transform.position.z);
camera.transform.LookAt(TeleportBooths[tc.WorkingBooth()].transform);
}
private void Update()
{
WorkingBooth();
}
}
After the line:
tc = GetComponent<TeleportationsCore>();
tc is null.
And this is the TeleportationsCore script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TeleportationsCore : MonoBehaviour
{
public float spinSpeed = 2.0f;
private bool rotate = false;
private bool exited = false;
private int boothIndex = 0;
private void Start()
{
WorkingBooth();
}
void OnTriggerEnter(Collider other)
{
if (other.gameObject.tag == "Player")
{
Debug.Log("Player entered the hole");
rotate = true;
}
}
private void OnTriggerExit(Collider other)
{
if (other.gameObject.tag == "Player")
{
Debug.Log("Player exited the hole");
rotate = false;
exited = true;
}
}
void Rotate()
{
if (rotate)
{
if (spinSpeed == 350)
{
rotate = false;
exited = true;
boothIndex++;
WorkingBooth();
}
else
{
transform.Rotate(Vector3.up, spinSpeed * Time.deltaTime);
spinSpeed += 1f;
}
}
if (rotate == false && exited == true)
{
transform.Rotate(Vector3.up, spinSpeed * Time.deltaTime);
if (spinSpeed > 0.0f)
spinSpeed -= 1f;
}
}
public int WorkingBooth()
{
return boothIndex;
}
private void Update()
{
Rotate();
}
}
Why tc is null all the time when running the game ?
Returns the component of Type type if the game object has one attached, null if it doesn't.
Therefore, tc would be null because the gameObject that the Teleport component is attached to does not have a TeleportationsCore component attached to it.
