Unity Camera垂直滚动效果

Question

我想创造一个像闲置矿工大亨一样的相机运动。因此，相机应该通过平移垂直滚动，具有典型的滚动效果。

这是我的代码：

Vector3 touchStart;
public int upperLimit = 0;
public int lowerLimit = 7000;

void Update()
{
if (Input.GetMouseButtonDown(0))
{
touchStart = Camera.main.ScreenToWorldPoint(Input.mousePosition);
}

if (Input.GetMouseButton(0))
{
Vector3 direction = touchStart - Camera.main.ScreenToWorldPoint(Input.mousePosition);
float finalYPos = Camera.main.transform.position.y + direction.y;
finalYPos = Mathf.Clamp(finalYPos, lowerLimit, upperLimit);
Camera.main.transform.position = new Vector3(Camera.main.transform.position.x, finalYPos, Camera.main.transform.position.z);
Debug.Log(finalYPos);
}
}

但是我怎样才能使滚动用完呢。事实上，当我离开鼠标/重击时，动作直接停止了。

感谢您的帮助

我为每个有相同问题的人找到了一个解决方案：

[SerializeField]
private Camera cam;
Vector3 touchStart;
private float topLimit = 0f;
private float bottomLimit = -2000.0f;
private Vector3 _curPosition;
private Vector3 _velocity;
private bool _underInertia;
private float _time = 0.0f;
public float SmoothTime = 2;
public Vector3 direction;
void Update()
{
PanCamera();
if (_underInertia && _time <= SmoothTime)
{
cam.transform.position += _velocity;
float newY = Mathf.Clamp(cam.transform.position.y, bottomLimit, topLimit);
cam.transform.position = new Vector3(cam.transform.position.x, newY, cam.transform.position.z);
_velocity = Vector3.Lerp(_velocity, Vector3.zero, _time);
_time += Time.smoothDeltaTime;
}
else
{
_underInertia = false;
_time = 0.0f;
}
}

private void PanCamera()
{
if (Input.GetMouseButtonDown(0))
{
touchStart = cam.ScreenToWorldPoint(Input.mousePosition);
_underInertia = false;
}
if (Input.GetMouseButton(0))
{
Vector3 _prevPosition = _curPosition;
direction = touchStart - cam.ScreenToWorldPoint(Input.mousePosition);
float finalYPos = cam.transform.position.y + direction.y;
Debug.Log("Old: " + finalYPos);
finalYPos = Mathf.Clamp(finalYPos, bottomLimit, topLimit);
Debug.Log("New: " + finalYPos);
Vector3 desiredPosition = new Vector3(cam.transform.position.x, finalYPos, cam.transform.position.z);
cam.transform.position = desiredPosition; 
_curPosition = desiredPosition;
_velocity = _curPosition - _prevPosition;
}
if (Input.GetMouseButtonUp(0))
{
_underInertia = true;
}
}
