Question

我正在尝试创建一个相机工具，允许相机围绕播放器旋转，然后在不再按住箭头键后重置其位置。但是当我试着

时

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CompleteCameraController : MonoBehaviour {

public Transform Player;
public float rotationSpeed = 10f;
public Vector3 offset;

private void Update()
{
        if (Input.GetKey(KeyCode.LeftArrow)){
            transform.RotateAround(Player.transform.position, Vector3.down, Time.deltaTime * 25);
        }
        if (Input.GetKey(KeyCode.RightArrow))
        {
            transform.RotateAround(Player.transform.position, Vector3.up, Time.deltaTime * 25);
        }
        if (Input.GetKey(KeyCode.UpArrow))
        {
            transform.RotateAround(Player.transform.position, Vector3.left, Time.deltaTime * 25);
        }
        if ((Player != null) && Input.GetKey(KeyCode.DownArrow))
        {
            transform.RotateAround(Player.transform.position, Vector3.right, Time.deltaTime * 25);
        }
        if (Input.GetKey(KeyCode.LeftArrow !=null))
        {
            transform.LookAt(Player.transform);
        }
    }
    void LateUpdate()
    {
        Vector3 desiredPosition = Player.position + offset;
        Vector3 smoothedPosition = Vector3.Lerp(transform.position, desiredPosition, rotationSpeed * Time.deltaTime);
        transform.position = smoothedPosition;
    }
}

Answer 1

你可能错在这里：

public async Task<PartialViewResult> GetStudent(int? id)
{           
    List<SchoolDto> schools;
    StudentDto student;

    using (var uow = UnitOfWorkManager.Begin(TransactionScopeOption.Suppress))
    {
        // Repository 1 (Database 1)
        student = await _studentAppService.GetStudentForEdit(new NullableIdDto { Id = id });
        uow.Complete();
    }

    using (var uow = UnitOfWorkManager.Begin(TransactionScopeOption.Suppress))
    {
        // Repository 2 (Database 2)
        schools = await _schoolAppService.GetSchoolList();
        uow.Complete();
    }

    // ...
}

不清楚为什么你有if (Input.GetKey(KeyCode.LeftArrow !=null))部分，删除它，你应该没事

Answer 2

问题在于

if (Input.GetKey(KeyCode.LeftArrow !=null))

您正在将KeyCode.LeftArrow与null进行比较，但这不起作用，因为它是枚举。我认为你可以安全地删除!=null部分，你会没事的。

更新

在您发表评论后，我认为您需要执行以下操作：

if ( !Input.GetKey(KeyCode.LeftArrow))
{
    transform.LookAt(Player.transform);
}

无法从bool转换为字符串
