Teleport / Respawn help

So I'm trying to have my character teleport / respawn when a condition is met. However, I'm having a problem with changing the character position. I set it up so when I press 'R' it moves the characters position to the position I specified. However, it doesn't always work the first time I press 'R'. Sometimes I have to press it upwards of 10 times for my character to finally move, however everytime I press the button the character does move to the position for a split second but then 'teleports' right back to where it was originally standing.

Here's the code I'm using to change my characters position. (attached to my player object)

Code (CSharp):

1. private Transform _respawn;
2. public Transform playerTransform;
3.  
4. void Start(){
5.    _respawn = GameObject.Find("Respawn").transform;
6.    playerTransform = this.gameObject.transform;
7. }
8.  
9. void Update(){
10.    if (Input.GetKeyDown(KeyCode.R))
11.       {
12.           playerTransform.transform.position = _respawn.transform.position;
13.       }

Here is a gif that also shows the problem in action, you will notice the camera jitter each time I press the teleport button, and the character moves right back to its original position.

EDIT:
After having another set of eyes look at the problem and keeping the controller possibly being the issue in mind I've found a fix.
Disabling the character controller, then teleporting, then re-enabling it seems to work like a charm.
Here is the updated code

Code (CSharp):

1. private Transform _respawn;
2. public Transform playerTransform;
3.  
4. void Start(){
5.    _respawn = GameObject.Find("Respawn").transform;
6.    playerTransform = this.gameObject.transform;
7. }
8.  
9. void Update(){
10.    if (Input.GetKeyDown(KeyCode.R))
11.       {
12.           _characterController.enabled = false;
13.           playerTransform.transform.position = _respawn.transform.position;
14.           _characterController.enabled = true;
15.       }
16. }

 

Something else must be setting the position every frame. Can we see the rest of the code?

 

The only other thing I have in my Update method is my Movement method, check it out.

Code (CSharp):

1. private void Movement()
2.     {
3.         float horizontalInput = Input.GetAxis("Horizontal");
4.         float verticalInput = Input.GetAxis("Vertical");
5.  
6.         Vector3 camForward_Dir = Vector3.Scale(Camera.main.transform.forward, new Vector3(1, 0, 1)).normalized;
7.         Vector3 move = verticalInput * camForward_Dir + horizontalInput * Camera.main.transform.right;
8.  
9.         if (move.magnitude > 1f)
10.         {
11.             move.Normalize();
12.         }
13.  
14.         move = transform.InverseTransformDirection(move);
15.         float turnAmount = Mathf.Atan2(move.x, move.z);
16.         transform.Rotate(0, turnAmount * rotationSpeed * Time.deltaTime, 0);
17.  
18.         if (_characterController.isGrounded)
19.         {
20.             anim.SetFloat("BlendX", horizontalInput);
21.             anim.SetFloat("BlendY", verticalInput);
22.             anim.SetBool("isJumping", false);
23.  
24.             _moveDir = transform.forward * move.magnitude;
25.             _moveDir *= speed;
26.  
27.             _verticalVelocity = -_gravityJump * Time.deltaTime;
28.  
29.             if (Input.GetButtonDown("Jump"))
30.             {
31.                 _verticalVelocity = jumpForce;
32.                 anim.SetBool("isJumping", true);
33.             }
34.         }
35.         else
36.         {
37.             _verticalVelocity -= _gravityJump * Time.deltaTime;
38.         }
39.  
40.         Vector3 jumpVector = new Vector3(0, _verticalVelocity, 0);
41.         _characterController.Move(jumpVector * Time.deltaTime);
42.  
43.         _moveDir.y -= _gravity * Time.deltaTime;
44.         _characterController.Move(_moveDir * Time.deltaTime);
45.     }

 

I believe the issue resides somewhere in the movement method because calling it after the if statement looking for the key press movement + teleporting stops working completely.

 

Probably _characterController is setting the transform position, as GroZZleR mentioned
