Unity 3d GoogleVR脚本不起作用

Question

我正在youtube上按照旧指南使用googleVR https://www.youtube.com/watch?v=kIATVY0sXuU&t=751s进行FPS。 创建者发布了这两个脚本。

using UnityEngine;
using System.Collections;

public class zombieScript : MonoBehaviour {
  //declare the transform of our goal (where the navmesh agent will move towards) and our navmesh agent (in this case our zombie)
  private Transform goal;
  private NavMeshAgent agent;

  // Use this for initialization
  void Start () {

    //create references
    goal = Camera.main.transform;
    agent = GetComponent<NavMeshAgent>();
    //set the navmesh agent's desination equal to the main camera's position (our first person character)
    agent.destination = goal.position;
    //start the walking animation
    GetComponent<Animation>().Play ("walk");
  }


  //for this to work both need colliders, one must have rigid body, and the zombie must have is trigger checked.
  void OnTriggerEnter (Collider col)
  {
    //first disable the zombie's collider so multiple collisions cannot occur
    GetComponent<CapsuleCollider>().enabled = false;
    //destroy the bullet
    Destroy(col.gameObject);
    //stop the zombie from moving forward by setting its destination to it's current position
    agent.destination = gameObject.transform.position;
    //stop the walking animation and play the falling back animation
    GetComponent<Animation>().Stop ();
    GetComponent<Animation>().Play ("back_fall");
    //destroy this zombie in six seconds.
    Destroy (gameObject, 6);
    //instantiate a new zombie
    GameObject zombie = Instantiate(Resources.Load("zombie", typeof(GameObject))) as GameObject;

    //set the coordinates for a new vector 3
    float randomX = UnityEngine.Random.Range (-12f,12f);
    float constantY = .01f;
    float randomZ = UnityEngine.Random.Range (-13f,13f);
    //set the zombies position equal to these new coordinates
    zombie.transform.position = new Vector3 (randomX, constantY, randomZ);

    //if the zombie gets positioned less than or equal to 3 scene units away from the camera we won't be able to shoot it
    //so keep repositioning the zombie until it is greater than 3 scene units away. 
    while (Vector3.Distance (zombie.transform.position, Camera.main.transform.position) <= 3) {

      randomX = UnityEngine.Random.Range (-12f,12f);
      randomZ = UnityEngine.Random.Range (-13f,13f);

      zombie.transform.position = new Vector3 (randomX, constantY, randomZ);
    }

  }

}

using UnityEngine;
using System.Collections;

public class playerScript : MonoBehaviour {

  //declare GameObjects and create isShooting boolean.
  private GameObject gun;
  private GameObject spawnPoint;
  private bool isShooting;

  // Use this for initialization
  void Start () {

    //only needed for IOS
    Application.targetFrameRate = 60;

    //create references to gun and bullet spawnPoint objects
    gun = gameObject.transform.GetChild (0).gameObject;
    spawnPoint = gun.transform.GetChild (0).gameObject;

    //set isShooting bool to default of false
    isShooting = false;
  }

  //Shoot function is IEnumerator so we can delay for seconds
  IEnumerator Shoot() {
    //set is shooting to true so we can't shoot continuosly
    isShooting = true;
    //instantiate the bullet
    GameObject bullet = Instantiate(Resources.Load("bullet", typeof(GameObject))) as GameObject;
    //Get the bullet's rigid body component and set its position and rotation equal to that of the spawnPoint
    Rigidbody rb = bullet.GetComponent<Rigidbody>();
    bullet.transform.rotation = spawnPoint.transform.rotation;
    bullet.transform.position = spawnPoint.transform.position;
    //add force to the bullet in the direction of the spawnPoint's forward vector
    rb.AddForce(spawnPoint.transform.forward * 500f);
    //play the gun shot sound and gun animation
    GetComponent<AudioSource>().Play ();
    gun.GetComponent<Animation>().Play ();
    //destroy the bullet after 1 second
    Destroy (bullet, 1);
    //wait for 1 second and set isShooting to false so we can shoot again
    yield return new WaitForSeconds (1f);
    isShooting = false;
  }

  // Update is called once per frame
  void Update () {

    //declare a new RayCastHit
    RaycastHit hit;
    //draw the ray for debuging purposes (will only show up in scene view)
    Debug.DrawRay(spawnPoint.transform.position, spawnPoint.transform.forward, Color.green);

    //cast a ray from the spawnpoint in the direction of its forward vector
    if (Physics.Raycast(spawnPoint.transform.position, spawnPoint.transform.forward, out hit, 100)){

      //if the raycast hits any game object where its name contains "zombie" and we aren't already shooting we will start the shooting coroutine
      if (hit.collider.name.Contains("zombie")) {
        if (!isShooting) {
          StartCoroutine ("Shoot");
        }

      }

    }

  }
}

第一个脚本应该使用NavMeshAgent移动僵尸，并且可以运行，但是：

1）僵尸只​​做步行动画2秒钟

2）当我使用第二个脚本中的项目符号时，僵尸应该使用“后备”动画，但它不起作用，您有什么解决办法吗？谢谢
