Determine mouse movement direction

[Paul L]

Anyone know a quick way of determining which direction the mouse cursor is
moving (ie. up, down, left, right) from a specified origin?

Thanks,

All you would need to do is take the origin (where the mouse was) and
take the current mouse position, then figure out what the greatest
difference axis is: x or y something like this:

if (System.Math.Ab s(origin.X - mouse.X) > System.Math.Abs (origin.Y -
mouse.Y))
{
// change in x is greater, now find left or right
if ((origin.X - mouse.X) < 0)
{
return "right";
}
else
{
return "left";
}
}
else
{
// change in y is greater, now find up or down
if ((origin.Y - mouse.Y) < 0)
{
return "up";
}
else
{
return "down";
}
}

You one thing to add - you can get the current mouse position with
MousePosition.X and MousePosition.Y .
