I'm trying to create QML code that rotates text in an
apparent "halo" (like around a circle/sphere). This should
be easy, but I can't figure out how to animate aspects of
a "transform: Rotation"
For example, the following displays text that properly
"rotates" back-and-forth, but I want to dynamically
change the "angle" in the Rotation transform to make
it "appear" that the text is "wrapping around" the circle
as it approaches the edges:
Text {
text: "hello world!"
// HOW TO ANIMATE CHANGES IN "angle" ???
transform: Rotation { origin.x: 100; origin.y: 100; axis { x: 0;
y: 1; z: 0 } angle: 72 }
smooth: true
SequentialAnimation on x {
loops: Animation.Infinite
NumberAnimation { to: 100; easing.type: Easing.InOutCubic;
duration: 2000 }
NumberAnimation { to: 0; easing.type: Easing.InOutCubic;
duration: 2000 }
}
}
I looked at "RotationAnimation", but I can't seem to get it
working right, and it doesn't seem to let me fiddle with
the "z" axis (I may later want to "tilt" the text front-or-back
by setting the z axis).
Suggestions? The goal is animated text-in-a-halo, possibly
with front-on tilt perspective (e.g., so the user can see the
"back" of the rotation with the text mirrored backwards).
The "transform: Rotation {}" appears to be absolutely
sufficient to get the proper "perspective" on the rotating
text, (so I know it can be done), but I'm open to any
suggestions.
Thanks!
