unity右键旋转相机视角完整代码

以下是一个简单的代码示例，用于在Unity中实现通过右键旋转相机视角：

public class CameraController : MonoBehaviour
{
    public float sensitivity = 5.0f; //鼠标灵敏度
    public float smoothing = 2.0f; //相机平滑度

    private Vector2 mouseLook; //相机视角
    private Vector2 smoothV; //相机平滑量

    void Update()
    {
        //获取鼠标移动量
        var md = new Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y"));

        //乘以灵敏度
        md = Vector2.Scale(md, new Vector2(sensitivity * smoothing, sensitivity * smoothing));

        //使用平滑量计算相机视角
        smoothV.x = Mathf.Lerp(smoothV.x, md.x, 1f / smoothing);
        smoothV.y = Mathf.Lerp(smoothV.y, md.y, 1f / smoothing);
        mouseLook += smoothV;

        //限制相机视角
        mouseLook.y = Mathf.Clamp(mouseLook.y, -90f, 90f);

        //旋转相机
        transform.localRotation = Quaternion.AngleAxis(-mouseLook.y, Vector3.right);
        transform.localRotation *= Quaternion.AngleAxis(mouseLook.x, Vector3.up);

        //按下右键时锁定光标
        if (Input.GetMouseButtonDown(1))
        {
            Cursor.lockState = CursorLockMode.Locked;
        }

        //松开右键时解锁光标
        if (Input.GetMouseButtonUp(1))
        {
            Cursor.lockState = CursorLockMode.None;
        }
    }
}

这个脚本可以将相机视角沿着水平和垂直轴旋转，使用了平滑量来使相机运动更加平滑。在按下右键时锁定光标，松开右键时解锁光标。
