基于Keydown的相机旋转

Question

所以我对Unity和c#真的很陌生，我只是在尝试一些东西。现在我想完善一下整体的控制体验。所以我希望当按下按钮A时，相机在Z轴上旋转5°。

这就是我所尝试的:

if (Input.GetKeyDown(KeyCode.A))
{
if (zRotation < 5f)
{
transform.localRotation = Quaternion.Euler(zRotation, 5f, 5f);
}
}

它在某种程度上起作用，相机在Z轴上旋转5°，但仅为1秒，然后返回到正常状态。

摄像机脚本的完整代码:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class mouseLook : MonoBehaviour
{
public float mouseSensitivity = 100f;
public Transform playerBody;
float xRotation = 0f;
float zRotation = 0f;
// Start is called before the first frame update
void Start()
{
Cursor.lockState = CursorLockMode.Locked;
}
// Update is called once per frame
void Update()
{
float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;
xRotation -= mouseY;
xRotation = Mathf.Clamp(xRotation, -90f, 90f);
transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
playerBody.Rotate(Vector3.up * mouseX);
if (Input.GetKeyDown(KeyCode.A))
{
if (zRotation < 5f)
{
transform.localRotation = Quaternion.Euler(zRotation, 5f, 5f);
}
}
}

}

我想让相机在按下按钮A时在Z轴上旋转5°。

您不需要任何变量来实现这一点，它应该像这样简单:

void Update()
{
if (Input.GetKeyDown(KeyCode.A))
{
cameraTransform.Rotate(0, 0, 5);
}     
}
