Tom

i trying to using UnityStandardAssets.Characters.FirstPerson but it don't work, can you help me? Here is my code:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityStandardAssets.Characters.FirstPerson;

public class PortalManager : MonoBehaviour

{

  [SerializeField]

  private Portal firstPortal;

  [SerializeField]

  private Portal secondPortal;

  [SerializeField]

  private Transform playerCam;

  private float magnitude;

  private Vector3 velocity;

  private RaycastHit hit;

  [SerializeField]

  private LayerMask rayMask;

  private List<objectPortal> currentObjects = new List<objectPortal>();

  // Start is called before the first frame update

  void Start()

  {

  }

  // Update is called once per frame

  void Update()

  {

  }

  public void PortalObject(bool isFirstPortal, GameObject currentObj)

  {

    objectPortal objectToCheck = GetObjectPortalByGameObject(currentObj);

    if (currentObjects.Contains(objectToCheck))

    {

      if (isFirstPortal && objectToCheck.currentPortal == firstPortal)

        return;

      if (!isFirstPortal && objectToCheck.currentPortal == secondPortal)

        return;

      currentObjects.Remove(objectToCheck);

    }

    Rigidbody tempRigid = currentObj.GetComponent<Rigidbody>();

    Vector3 pos = Vector3.zero;

    Vector3 rot = Vector3.zero;

    magnitude = tempRigid.velocity.magnitude;

    objectPortal newObject = new objectPortal();

    Portal newPortal = firstPortal;

    if (!isFirstPortal)

      newPortal = secondPortal;

    pos = newPortal.transform.position;

    if (!newPortal.gameObject.activeSelf)

      return;

    rot = newPortal.transform.rotation.eulerAngles;

    velocity = newPortal.transform.forward;

    newObject.currentPortal = newPortal;

    newObject.currentGameObject = currentObj;

    currentObjects.Add(newObject);

    tempRigid.velocity = Vector3.zero;

    if (currentObj.layer == 8)

      pos += newPortal.transform.forward * 1.3f;

    currentObj.transform.position = pos;

    if(currentObj.layer == 8)

    {

      currentObj.GetComponent<>

    }

    else

    {

      currentObj.transform.rotation = Quaternion.Euler(rot);

    }

  }

  public void SetPortal(Portal currentPortal)

  {

    if (Physics.Raycast(playerCam.position, playerCam.forward, out hit, 100, rayMask))

    {

      if (hit.transform.gameObject.layer == 17)

        return;

      currentPortal.gameObject.SetActive(true);

      currentPortal.transform.position = hit.point;

      currentPortal.transform.rotation = Quaternion.LookRotation(hit.normal);

    }

  }

  public IEnumerator RemoveObject(objectPortal removeObjectPortal)

  {

    yield return new WaitForSeconds(0.1f);

    if (!currentObjects.Contains(removeObjectPortal))

      yield break;

    currentObjects.Remove(removeObjectPortal);

  }

  public objectPortal GetObjectPortalByGameObject(GameObject objectToCheck)

  {

    for (int i = 0; i < currentObjects.Count; i++)

    {

      if (currentObjects[i].currentGameObject == objectToCheck)

        return currentObjects[i];

    }

    return new objectPortal();

  }

}
