a relation between Touch Move and Screen Size

i want to move camera
no matter touch or mouse , maybe it has a relation between deltaposition and screensize,i think.


1. i want to , finger's equal with camera in deltapostion
2. finger's deltapsition better than camera position , when screen size is too large
3. finger's deltapsition less than camera position , when screen size is too small

e.g screen aspect is 1280 800. let's reduce it acrroding to the proportion. it will show "2".

how can i handle it...

 

Hi daniel,
You can do the code given below.
if(Input.GetMouseButtonDown(1))
{

mouseOrigin = Input.mousePosition;
isPanning = true;
}
if (isPanning)
{
Vector3pos = Camera.main.ScreenToViewportPoint(Input.mousePosition - mouseOrigin);
Vector3move = newVector3(pos.x * panSpeed, pos.y * panSpeed, 0);
transform.Translate(move, Space.Self);
}

Thanks
