Question

我使用youtube示例实现了一个帮助脚本。但是当我在其他脚本中使用Resource方法时，编译器会给出null引用错误。我做错了什么。

这是我的帮助脚本以及如何调用资源。

using UnityEngine;
 using System.Collections;

 namespace Helper
 {
 public class Resource
     {
         public static string AnimatorController = "System/PlayerAnimator";
     }
 }

根据我的场景的路径是

资产/资源/系统/ PlayerAnimator.controller

这是我在其他脚本中用来加载资源的方式

     private Animator _animator;
     private RuntimeAnimatorController _animatorController;

  _animatorController = Resources.Load(Resource.AnimatorController) as RuntimeAnimatorController;
  _animator.runtimeAnimatorController = _animatorController;

对此有什么解决方法？

我添加了两个脚本。非无效

PlayerCharctor.cs

using UnityEngine; using System.Collections; using Helper;


[RequireComponent(typeof(NetworkView))] [RequireComponent(typeof(CharacterController))] [RequireComponent(typeof(Animator))]

[RequireComponent(typeof(PlayerMotor))] [RequireComponent(typeof(PlayerCamera))]

[AddComponentMenu("Scripts/Player/PlayerCharacter")] public class PlayerCharacter : MonoBehaviour {

    #region Variables & Properties (Private)

    private CharacterController _controller;
    private Animator _animator;
    private RuntimeAnimatorController _animatorController;



    #endregion

    #region Variables & Properties (Public)
    public CharacterController Controller
    {
        get
        {
            return _controller;
        }


    }

    public Animator Animator
    {
        get
        {
            return _animator;
        }


    }

    #endregion

    #region Unity Event Funtions

    void awake()
    {
        _animator = GetComponent<Animator>();
        _controller = GetComponent<CharacterController>();
    }

    // Use this for initialization
    void Start ()
    {

            //Ensure networkview Component exists 
            if (GetComponent<NetworkView>() != null)
            {
                //Ensure that initialization only executes if this is a valid instance
                if (GetComponent<NetworkView>().isMine || Network.peerType == NetworkPeerType.Disconnected)
                {
                //Load in the AnimatorController at runtime
                _animatorController = Resources.Load(Resource.AnimatorController) as RuntimeAnimatorController;
                _animator.runtimeAnimatorController = _animatorController;







                _controller.center = new Vector3(0f, 1f, 0f);
                    _controller.height = 1.8f;
                }
                else
                {
                    enabled = false;
                }
            }
            else
            {
                Debug.Log("Attach a NetWorkViewComponent!!");
            }




    }

Answer 1

从Resources加载资源的代码没有问题。但实际上可能是因为你的_animator变量。我99％确定它是null。首先获取Animator组件_animator = GetComponent<Animator>();，然后分配其RuntimeAnimatorController。

在团结5中，资源不会在运行时加载到我的场景中？
