Camera vertically scrolling effect (scroll out)

Archived Forums Questions & Answers

I want to create a camera movement like idle miner tycoon. So the Camera should scroll vertically by panning with a typically scroll effect.

This is my code:

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);
    }
}

But how can I make that the scrolling is ran out. Actually the movement is stopping directly when I leave the mouse/thump.

Thank you for your help

Best regards

I found a Solution for everybody, who has the same problem:

   [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;

        }
    }
