Getting mouse movement speed (all axis)

Questions & Answers
1

Hi.

Title pretty much says it all. I’d like to know how fast the mouse is moving, in all the axis as one value. Mouse input returns either x or y axis, but I only need the speed. How can I calculate it?

Thanks,

Luka

This script will Debug the changes in the mouse position between frames when you click or hold the mouse button. These values are stored in delta.x and delta.y :

#pragma strict

public var delta : Vector3 = Vector3.zero;
private var lastPos : Vector3 = Vector3.zero;

function Update()
{
    if ( Input.GetMouseButtonDown(0) )
    {
        lastPos = Input.mousePosition;
    }
    else if ( Input.GetMouseButton(0) )
    {
        delta = Input.mousePosition - lastPos;

        // Do Stuff here
		
		Debug.Log( "delta X : " + delta.x );
		Debug.Log( "delta Y : " + delta.y );
		
		Debug.Log( "delta distance : " + delta.magnitude );

        // End do stuff

        lastPos = Input.mousePosition;
    }
}

you can get the result from the following function, I think that’s why they did not provide anything like “Input.mousePosition.Delta()”

Input.GetAxis("Mouse X");
Input.GetAxis("Mouse Y");
