c# - Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y") 总是返回 0

Question

我为 3d 射击游戏添加了主要用户对象，为其附加了摄像头，并试图在脚本代码中捕捉鼠标移动，并附加到玩家游戏对象上。但不能使用Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y")，因为它们始终为零。为什么？我做错了什么？Input.GetAxis("Vertical")并且Input.GetAxis("Horizontal")对于键工作良好。

using UnityEngine;
using System.Collections;

public class MouseLook : MonoBehaviour {

  public enum RotationAxes {
    MouseXAndY = 0,
    MouseX = 1,
    MouseY = 2
  }

  public RotationAxes axes = RotationAxes.MouseXAndY;
  public float sensitivityHor = 9.0f;
  public float sensitivityVert = 9.0f;
  public float minimumVert = -45.0f;
  public float maximumVert = 45.0f;
  private float _rotationX = 0;

  void Start() {
    Rigidbody body = GetComponent<Rigidbody>();
    if (body != null)
      body.freezeRotation = true;
  }

  void Update() {
    Debug.Log(Input.GetAxis("Mouse X"));
    Debug.Log(Input.GetAxis("Mouse Y"));
    if (axes == RotationAxes.MouseX) {
      transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityHor, 0);
    } else if (axes == RotationAxes.MouseY) {
      _rotationX -= Input.GetAxis("Mouse Y") * sensitivityVert;
      _rotationX = Mathf.Clamp(_rotationX, minimumVert, maximumVert);
      float rotationY = transform.localEulerAngles.y;
      transform.localEulerAngles = new Vector3(_rotationX, rotationY, 0);
    } else {
      _rotationX -= Input.GetAxis("Mouse Y") * sensitivityVert;
      _rotationX = Mathf.Clamp(_rotationX, minimumVert, maximumVert);
      float delta = Input.GetAxis("Mouse X") * sensitivityHor;
      float rotationY = transform.localEulerAngles.y + delta;
    }

我希望Input.GetAxis("Mouse X") 的输出从 -1 到 1，但实际输出为 0。我在Debug.Log.

检查您的统一输入设置，Mouse X并Mouse Y应定义如下：
