orthographic camera movement on LMB+mouse move

Unity Engine
1

I am looking for a script that with the orthographic camera on LeftMouseButton Down + MouseMove Left, Right, up down. Camera.main.position X-- / X++ or y-- /y++.

Just think of the movement in google maps or other map packages.

Input.mousePosition: tells you where the mouse is in screen coordinates. Each Update(), compare mousePosition to the last stored value to calculate a delta; apply the delta (scaled appropriately) to your camera position; and update the stored value.

I think you can use:

Input.GetAxis (“Mouse X”) > 0
Input.GetAxis (“Mouse X”) < 0
Input.GetAxis (“Mouse Y”) > 0
Input.GetAxis (“Mouse Y”) < 0

But you need to take care of the acceleration

Okay thanks guys. Now the camera translation / position function is camera.main.Transform.position(x,y,z)? the scripting reference gives information that the camera is in the typical x,y,z placement but doesn’t give any examples of a camera position transform.

If I wanted to add the Left Mouse button with mouse movement I am guessing one section of the script would be:

if(Input.GetMouseButtonDown(0))
{
if ( (Input.GetAxis(“Mouse X”)>0) )
{
Debug.Log(“Pressed left click and moved mouse X”);
//not sure how to transform position of camera.

camera.transform.position = new Vector3 (increment a float X somehow somewhere?,y,z)
}
}

How about (untested):

if (Input.GetMouseButton(0)) {
  camera.transform.position += camera.transform.right * Input.GetAxis("Mouse X") * sensitivityX;
  camera.transform.position += camera.transform.up * Input.GetAxis("Mouse Y") sensitivityY;
}

The point is, you need to transform mouse motion into world-space motion, not just apply it axially.
