Two things come to mind: 1. Use relative moves instead of absolute moves. E.g. instead of "359° to 1°", do "359° + 2°" 2. Support values <= 0° and >= 360°. E.g. instead of "359° to 1°", do "359° to 361°". After the animation is done, you can normalize "361°" -> "1°" (optional) Regards, Sze-Howe > Sent: Monday, January 29, 2018 at 1:23 PM > From: "Ola Røer Thorsen" <o...@silentwings.no> > To: No recipient address > Cc: "interestqt-project.org" <interest@qt-project.org> > Subject: Re: [Interest] How to make a looping element? > Try the RotationAnimation item and set the direction property to shortest. > http://doc.qt.io/qt-5/qml-qtquick-rotationanimation.html > > Cheers, > Ola > > > Den 29. jan. 2018 kl. 02.15 skrev Jason H <jh...@gmx.com>: > > > I am trying to make a compass control, something that shows 0-360, like a > boat compass.
