Player position not synchronizing [Photon Transform View]

Dear communty, I've been programming a photon multiplayer game in unity for a few days. When I create a room I can't move until a second player joins (but that doesn't matter for now). The real problem comes when a second player joins. The player controller for the second player is spawned and I can move freely, but my movement change is not displayed on the other player's screen. There I just stand still, although I have already moved a long way.

Here are 2 pictures of my player prefab:

And yes, I noticed it too. There are two transform views on the prefab (classic and normal) but one is disabled. In that respect it shouldn't be a problem. It didn't work even with just one.

Here is a screenshot of my first person camera (I think the error is somewhere here):

I've added the photon view here again because the 'First Person Look Script' checks 'if (!photonView.IsMine)' again. And if I hadn't attached the Photon view I would of course get a NullReferenceException. I think thats the error, but how should I do it if not like this?

Here is a picture of the hierarchy of my prefab:

I got the base of the player controller from the unity asset store (https://assetstore.unity.com/packages/tools/input-management/mini-first-person-controller-174710).

Here are some of the player controller scripts that might be useful:

FirstPersonLook:

Code (CSharp):

using

UnityEngine;

using

Photon.Pun;

public class

FirstPersonLook : MonoBehaviour
{
[SerializeField]
Transform character;

public float

sensitivity = 2;

public float

smoothing = 1.5f;
Vector2 velocity;
Vector2 frameVelocity;
PhotonView photonView;

void

Reset()
{

// Get the character from the FirstPersonMovement in parents.
character = GetComponentInParent().transform;
}

void

Start()
{

// Lock the mouse cursor to the game screen.
Cursor.lockState = CursorLockMode.Locked;
photonView = GetComponent();
}

void

Update()
{

(!photonView.IsMine)
{

// Get smooth velocity.

Vector2 mouseDelta = new

Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y"));
Vector2 rawFrameVelocity = Vector2.Scale(mouseDelta, Vector2.one * sensitivity);
frameVelocity = Vector2.Lerp(frameVelocity, rawFrameVelocity, 1 / smoothing);
velocity += frameVelocity;
velocity.y = Mathf.Clamp(velocity.y, -90, 90);

// Rotate camera up-down and controller left-right from velocity.
transform.localRotation = Quaternion.AngleAxis(-velocity.y, Vector3.right);
character.localRotation = Quaternion.AngleAxis(velocity.x, Vector3.up);
}
}
}

FirstPersonMovement:

Code (CSharp):

using

System.Collections.Generic;

using

UnityEngine;

using

Photon.Pun;
public class FirstPersonMovement : MonoBehaviour
{

public float

speed = 5;
[Header("Running")]
public bool canRun = true;

public bool IsRunning { get; private set

public float

runSpeed = 9;

public

KeyCode runningKey = KeyCode.LeftShift;
public GameObject bullet;

public

Transform firePoint;

public

AudioSource shootingSound;
PhotonView photonView;
Rigidbody rigidbody;

///
Functions to override movement speed. Will use the last added override.

public List<System.Func<float>> speedOverrides = new List<System.Func<float

();
void Awake()
{

// Get the rigidbody on this.
rigidbody = GetComponent();
}

private void

Start()
{
photonView = GetComponent();
}

void

FixedUpdate()
{

(!photonView.IsMine)
{

// Update IsRunning from input.
IsRunning = canRun && Input.GetKey(runningKey);

// Get targetMovingSpeed.

float

targetMovingSpeed = IsRunning ? runSpeed : speed;
if (speedOverrides.Count > 0)
{
targetMovingSpeed = speedOverridesspeedOverrides.Count - 1;
}

// Get targetVelocity from input.

Vector2 targetVelocity =new

Vector2( Input.GetAxis("Horizontal") * targetMovingSpeed, Input.GetAxis("Vertical") * targetMovingSpeed);

// Apply movement.

rigidbody.velocity = transform.rotation * new

Vector3(targetVelocity.x, rigidbody.velocity.y, targetVelocity.y);

// Shooting

(Input.GetMouseButtonDown(0))
{
Instantiate(bullet, firePoint.position, firePoint.rotation);
shootingSound.Play();
}
}

/// Update IsRunning from input.*
IsRunning = canRun && Input.GetKey(runningKey);
// Get targetMovingSpeed.
float targetMovingSpeed = IsRunning ? runSpeed : speed;
if (speedOverrides.Count > 0)
{
targetMovingSpeed = speedOverridesspeedOverrides.Count - 1;
}
// Get targetVelocity from input.
Vector2 targetVelocity =new Vector2( Input.GetAxis("Horizontal") * targetMovingSpeed, Input.GetAxis("Vertical") * targetMovingSpeed);
// Apply movement.
rigidbody.velocity = transform.rotation * new Vector3(targetVelocity.x, rigidbody.velocity.y, targetVelocity.y);
// Shooting
if(Input.GetMouseButtonDown(0))
{
Instantiate(bullet, firePoint.position, firePoint.rotation);
shootingSound.Play();
}/*
}
}

Jump:

Code (CSharp):

using

UnityEngine;

using

Photon.Pun;

public class

Jump : MonoBehaviour
{
Rigidbody rigidbody;

public float

jumpStrength = 2;

public event

System.Action Jumped;
[SerializeField, Tooltip("Prevents jumping when the transform is in mid-air.")]
GroundCheck groundCheck;
PhotonView photonView;
void Reset()
{

// Try to get groundCheck.
groundCheck = GetComponentInChildren();
}

void

Awake()
{

// Get rigidbody.
rigidbody = GetComponent();
}

private void

Start()
{
photonView = GetComponent();
}

void

LateUpdate()
{

(!photonView.IsMine)
{

// Jump when the Jump button is pressed and we are on the ground.

(Input.GetButtonDown("Jump") && (!groundCheck || groundCheck.isGrounded))
{
rigidbody.AddForce(Vector3.up * 100 * jumpStrength);
Jumped?.Invoke();
}
}
}
}

Crouch:

Code (CSharp):

using

UnityEngine;

using

Photon.Pun;

public class

Crouch : MonoBehaviour
{

public

KeyCode key = KeyCode.LeftControl;
[Header("Slow Movement")]
[Tooltip("Movement to slow down when crouched.")]
public FirstPersonMovement movement;
[Tooltip("Movement speed when crouched.")]

public float

movementSpeed = 2;
[Header("Low Head")]
[Tooltip("Head to lower when crouched.")]

public

Transform headToLower;
[HideInInspector]

public float

? defaultHeadYLocalPosition;

public float

crouchYHeadPosition = 1;
[Tooltip("Collider to lower when crouched.")]

public

CapsuleCollider colliderToLower;
[HideInInspector]

public float

? defaultColliderHeight;

public bool IsCrouched { get; private set

public event

System.Action CrouchStart, CrouchEnd;
PhotonView photonView;

void

Reset()
{

// Try to get components.
movement = GetComponentInParent();
headToLower = movement.GetComponentInChildren().transform;
colliderToLower = movement.GetComponentInChildren();
}

private void

Start()
{
photonView = GetComponent();
}

void

LateUpdate()
{

(!photonView.IsMine)
{

(Input.GetKey(key))
{

// Enforce a low head.

(headToLower)
{

// If we don't have the defaultHeadYLocalPosition, get it now.

(!defaultHeadYLocalPosition.HasValue)
{
defaultHeadYLocalPosition = headToLower.localPosition.y;
}

// Lower the head.

headToLower.localPosition =new

Vector3(headToLower.localPosition.x, crouchYHeadPosition, headToLower.localPosition.z);
}

// Enforce a low colliderToLower.

(colliderToLower)
{

// If we don't have the defaultColliderHeight, get it now.

(!defaultColliderHeight.HasValue)
{
defaultColliderHeight = colliderToLower.height;
}

// Get lowering amount.

float

loweringAmount;

(defaultHeadYLocalPosition.HasValue)
{

loweringAmount = defaultHeadYLocalPosition.Value

- crouchYHeadPosition;
}

else
{
loweringAmount = defaultColliderHeight.Value * .5f;
}

// Lower the colliderToLower.

colliderToLower.height = Mathf.Max(defaultColliderHeight.Value

- loweringAmount, 0);
colliderToLower.center = Vector3.up * colliderToLower.height * .5f;
}

// Set IsCrouched state.

(!IsCrouched)
{

IsCrouched = true

;

SetSpeedOverrideActive(true

);
CrouchStart?.Invoke();
}
}

else
{

(IsCrouched)
{

// Rise the head back up.

(headToLower)
{

headToLower.localPosition = new Vector3(headToLower.localPosition.x, defaultHeadYLocalPosition.Value

, headToLower.localPosition.z);
}

// Reset the colliderToLower's height.

(colliderToLower)
{

colliderToLower.height = defaultColliderHeight.Value

;
colliderToLower.center = Vector3.up * colliderToLower.height * .5f;
}

// Reset IsCrouched.

IsCrouched = false

;
SetSpeedOverrideActive(false);
CrouchEnd?.Invoke();
}
}
}
}
#region Speed override.

void SetSpeedOverrideActive(bool

state)
{

// Stop if there is no movement component.

(!movement)
{

return

;
}

// Update SpeedOverride.

(state)
{

// Try to add the SpeedOverride to the movement component.

(!movement.speedOverrides.Contains(SpeedOverride))
{

movement.speedOverrides.Add

(SpeedOverride);
}
}

else
{

// Try to remove the SpeedOverride from the movement component.

(movement.speedOverrides.Contains(SpeedOverride))
{

movement.speedOverrides.Remove

(SpeedOverride);
}
}
}

float

SpeedOverride() => movementSpeed;
#endregion
}

I think that should be enough. If anything else is needed just let me know.

Thank you for helping me!

Kind regards, jcjms.
