Can you explain what you mean by "slide rotating"? These are some of the functions that I know, I explain them to you in case it is what you are looking for:
speed: the speed of the mouse (Vector2), 0, 0 if the mouse is still.
position: current position.
relative: the last position of the mouse in the previous frame, but relative to the current position.
tilt: the rotation of the pen (or mouse slide rotating? ), on tablets to draw as wacom.
if event is InputEventMouseMotion:
print("Speed: ", event.speed)
print("Position: ", event.position)
print("Relative last position: ", event.relative)
print("Tilt: ", event.tilt)
