Animate a plane along an endless line

[plan_rich]

I'm quite new to QML and I'm trying to program a little game.

I'm trying to animate a plane flying along an endless line. If the rotation of the plane changes the plane updates it's path (line). I implemented this feature in js, but the problem is that the animations are never smooth.

Using any animation like NumberAnimation the plane moves very smooth, but these Animations are all from-to based, so I can move from A to B but I cannot (or I dont know how) move the plane continuous along an endless line using a NumberAnimation.

Any suggestions?
