1.上下顶点锁定

将摄像机放在某对象下面作为子类
父类左右旋转，摄像机上下旋转

public class MoveCameraAlpha : MonoBehaviour
{[Header("旋转速度")][Range(0,1)]public float turnSpeed;//Main Camera的父类private Transform _cameraFather;private float _mousex;private float _mousey;private float xAxisClamp;private void Awake(){_cameraFather = transform.root;}private void Start(){Cursor.lockState = CursorLockMode.Locked;xAxisClamp = 0.0f;}private void Update(){if (Input.GetMouseButton(1)){_mousex = Input.GetAxis("Mouse X");_mousey = Input.GetAxis("Mouse Y");xAxisClamp += _mousey;//Debug.Log(xAxisClamp);if (xAxisClamp > 90.0f){xAxisClamp = 90.0f;_mousey = 0.0f;ClampXAxisRotationToValue(270.0f);}else if (xAxisClamp < -90.0f){xAxisClamp = -90.0f;_mousey = 0.0f;ClampXAxisRotationToValue(90.0f);}_cameraFather.Rotate(Vector3.up * _mousex);transform.Rotate(Vector3.left * _mousey);Vector3 res = new Vector3(transform.eulerAngles.x, transform.eulerAngles.y, 0);transform.eulerAngles = res;}}private void ClampXAxisRotationToValue(float value){Vector3 eulerRotation = transform.eulerAngles;eulerRotation.x = value;transform.eulerAngles = eulerRotation;}
}

或

public class MoveCameraAlpha : MonoBehaviour
{[Header("旋转速度")][Range(0,1)]public float turnSpeed;//Main Camera的父类private Transform _cameraFather;private float _mousex;private float _mousey;private float xAxisClamp;private void Awake(){_cameraFather = transform.root;}private void Start(){Cursor.lockState = CursorLockMode.Locked;xAxisClamp = 0.0f;}private void Update(){if (Input.GetMouseButton(1)){_mousex = Input.GetAxis("Mouse X");_mousey = Input.GetAxis("Mouse Y");xAxisClamp -= _mousey;//Debug.Log(xAxisClamp);xAxisClamp = Mathf.Clamp(xAxisClmap,-90f,90f);_cameraFather.Rotate(Vector3.up * _mousex);transform.localRotation = Quaternion.Euler(xAxisClamp,0f,0f);}}
}

2.镜头上下了连续旋转

public class MoveCamera : MonoBehaviour
{[Header("移动速度")]public float moveSpeed;[Header("旋转速度")][Range(0,1)]public float turnSpeed;private float _hor;private float _ver;private float _mousex;private float _mousey;private float _yaw;private float _pitch;private void Start(){Cursor.lockState = CursorLockMode.Locked;_yaw = transform.eulerAngles.y;_pitch = transform.eulerAngles.x;}private void Update(){if (Input.GetMouseButton(1)){_hor = Input.GetAxis("Horizontal");_ver = Input.GetAxis("Vertical");transform.position += _hor * transform.right * Time.deltaTime * moveSpeed + _ver * transform.forward * Time.deltaTime * moveSpeed;_mousex = Input.GetAxis("Mouse X");_mousey = Input.GetAxis("Mouse Y");//方法一，到顶点会快速水平旋转// transform.Rotate(-_mousey, _mousex, 0);// Vector3 res = new Vector3(transform.eulerAngles.x, transform.eulerAngles.y, 0);// transform.eulerAngles = res;//方法二，没问题的实现_yaw = (_yaw + _mousex) % 360f;_pitch = (_pitch - _mousey) % 360f;transform.rotation = Quaternion.AngleAxis(_yaw, Vector3.up) * Quaternion.AngleAxis(_pitch, Vector3.right);//方法三,到顶点会水平旋转180度// transform.forward = Quaternion.AngleAxis(_mousex, Vector3.up) * transform.forward;// transform.forward = Quaternion.AngleAxis(-_mousey, Vector3.right) * transform.forward;}}
}
