Creating portals

Hi,

I am trying to make a portal like the following video, however, when I turn the receiving portal by 90 degree, the player is teleported but the direction of the camera did not rotate accordingly (i.e. by 90 degree). How should I modify the following code for that? I am a beginner in Unity please help.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class TeleportPlane2 : MonoBehaviour
6. {
7.  
8.     public Transform player;
9.     public Transform receiver;
10.  
11.     private bool playerIsOverlapping = false;
12.  
13.     // Update is called once per frame
14.     void Update()
15.     {
16.         if (playerIsOverlapping)
17.         {
18.             Vector3 portalToPlayer = player.position - transform.position;
19.             float dotProduct = Vector3.Dot(transform.up, portalToPlayer);
20.  
21.             //If this is true: The player has moved across the portal
22.             if (dotProduct < 0f)
23.             {
24.                 //Teleport him!
25.                 float rotationDiff = -Quaternion.Angle(transform.rotation, receiver.rotation);
26.                 rotationDiff += 180;
27.                 player.Rotate(Vector3.up, rotationDiff);
28.  
29.                 Vector3 positionOffset = Quaternion.Euler(0f, rotationDiff, 0f) * portalToPlayer;
30.                 player.position = receiver.position + positionOffset;
31.  
32.                 playerIsOverlapping = false;
33.  
34.  
35.             }
36.         }
37.     }
38.  
39.     void OnTriggerEnter(Collider collider)
40.     {
41.         if (collider.name == "Player")
42.         {
43.             playerIsOverlapping = true;
44.         }
45.     }
46.     void OnTriggerExit(Collider collider)
47.     {
48.         if (collider.name == "Player")
49.         {
50.             playerIsOverlapping = false;
51.         }
52.  
53.     }
54. }
55.  

 

I've answered questions to this very same tutorial multiple times now... funny.

Like here:
https://forum.unity.com/threads/quaternion-question.540705/#post-3564999

And here was the original time I did:
https://forum.unity.com/threads/portals.522231/

Here's even a fork I did of the original project and made the appropriate changes so the code from the tutorial ACTUALLY works:

Cause yeah, the tutorial was written badly.
