Question

我收到此错误：

NullReferenceException：未将对象引用设置为对象的实例

UnityEditor.Graphs.AnimationStateMachine.GraphGUI.SyncGraphToUnitySelection（布尔力）（在C：/buildslave/unity/build/Editor/Graphs/UnityEditor.Graphs/AnimationStateMachine/GraphGUI.cs：310）
  UnityEditor.Graphs.AnimatorControllerTool.DetectAnimatorControllerFromSelection（）（在C：/buildslave/unity/build/Editor/Graphs/UnityEditor.Graphs/Animation/AnimatorControllerTool.cs：734）
  UnityEditor.Graphs.AnimatorControllerTool.OnEnable（）（在C：/buildslave/unity/build/Editor/Graphs/UnityEditor.Graphs/Animation/AnimatorControllerTool.cs：747）

这是我的代码（团结2017.3.0f3）

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour {

    public float moveSpeed;

    private Animator anim;

    // Use this for initialization
    void Start () {
        anim = GetComponent<Animator>();    
    }

    // Update is called once per frame
    void Update () {
        if (Input.GetAxisRaw("Horizontal") > 0.5f || Input.GetAxisRaw("Horizontal") < -0.5f)
        {
            transform.Translate(new Vector3(Input.GetAxisRaw("Horizontal") * moveSpeed * Time.deltaTime, 0f, 0f));          
        }

        if (Input.GetAxisRaw("Vertical") > 0.5f || Input.GetAxisRaw("Vertical") < -0.5f)
        {
            transform.Translate(new Vector3(0f, Input.GetAxisRaw("Vertical") * moveSpeed * Time.deltaTime, 0f));
        }
    }

    anim.SetFloat("MoveX", Input.GetAxisRaw("Horizontal"));
    anim.SetFloat("MoveY", Input.GetAxisRaw("Vertical")); 
}

Answer 1

我不知道这是否有效，但你可以试试这个：

public GameObject animObject;
private Animator anim;

void Start () {
anim = animObject.GetComponent<Animator>();
}

In＆＃34; animObject＆＃34;获取您打算制作动画的GameObject的动画制作者。

Anim.SetFloat不起作用
