The mouse cursor moves in a straight line between its current position and the destination set with hs.mouse.absolutePosition(). If the mouse is moving to a new screen, it can get caught on a corner that does not connect between screens, depending on the screen sizes and layout. When moving the mouse between screens, first move the mouse to the center of the current screen, then to the center of the new screen, then the target destination. This path has the best chance at avoiding any non-connected edges between screens. These extra mouse movements happen instantaneously and are not visible to the user.

Note, this approach may still fail for more complex screen layouts (like three monitors in an "L" shape). But should be suitable for the majority of users and doesn't require any sophisticated mouse cursor route planning. |
