摄像头视角对齐Scene视角

选中camera对象，然后菜单栏gameobject—>align with view，或者直接使用快捷键ctrl+shift+f

在 Game 视图中，像 Scene 视图中一样移动视角

为 Camera 对象挂接下面的脚本即可：

using UnityEngine;

public class MoveCamera : MonoBehaviour
{
    private float Speed = 5;
    private Vector3 MouseDownPos;

    void Update()
    {
        Vector3 Face = transform.rotation * Vector3.forward;
        Face = Face.normalized;

        Vector3 Left = transform.rotation * Vector3.left;
        Left = Left.normalized;

        Vector3 Right = transform.rotation * Vector3.right;
        Right = Right.normalized;

        //Debug.Log(transform.rotation * Vector3.forward + "," + transform.rotation * Vector3.left + "," + transform.rotation * Vector3.right);

        if (Input.GetMouseButtonDown(1))
        {
            MouseDownPos = Input.mousePosition;
        }

        if (Input.GetMouseButton(1))
        {
            //Vector处理
            Vector3 Save = Input.mousePosition;
            Vector3 MovePos = Save - MouseDownPos;
            MovePos = MovePos.normalized;
            Vector3 _Rot = transform.rotation.eulerAngles;

            _Rot.x -= MovePos.y;
            _Rot.y += MovePos.x;
            _Rot.z += MovePos.z;
            transform.eulerAngles = _Rot;
            Debug.Log(MovePos);
            MouseDownPos = Save;
        
            //Quaternion处理
            // Vector3 Save = Input.mousePosition;
            // Vector3 MovePos = Save - MouseDownPos;
            // MovePos = MovePos.normalized;
            // Vector3 _Rot = transform.rotation.eulerAngles;
            // _Rot.x -= MovePos.y * 2;
            // _Rot.y += MovePos.x * 2;
            // _Rot.z += MovePos.z * 2;
            // Quaternion MoveRot = Quaternion.Euler(_Rot);
            // transform.rotation = Quaternion.Slerp(transform.rotation, MoveRot, Time.deltaTime * 30);
            // MouseDownPos = Save;
        }

        if (Input.GetKey("w"))
        {
            transform.position += Face * Speed * Time.deltaTime;
        }

        if (Input.GetKey("a"))
        {
            transform.position += Left * Speed * Time.deltaTime;
        }

        if (Input.GetKey("d"))
        {
            transform.position += Right * Speed * Time.deltaTime;
        }

        if (Input.GetKey("s"))
        {
            transform.position -= Face * Speed * Time.deltaTime;
        }

        if (Input.GetKey("q"))
        {
            transform.position -= Vector3.up * Speed * Time.deltaTime;
        }

        if (Input.GetKey("e"))
        {
            transform.position += Vector3.up * Speed * Time.deltaTime;
        }

    }
}
