Hi,
I found out that ParallelAnimation is not truly parallel, if I try to
animate to objects
moving next to one and other, like train wagons, I get overlaps.
They are parallel afaik.
Can you give a self-contained testcase?
What could be happening is some kind of pixel adjustment during the
animation. The x,y,width,height values are real numbers that are
rounded to an int when mapping to the display, so 1-pixel shifts could
happen due that fact.
It's much more than 1-pixel, like tens of pixels. In some cases it
looks like they are serialized.
But it is not consistent, happens only maybe 1/10 times. Looks like
some display list order
is arbitrary.
I'll see if I can get together a test case when I have time.
Btw. I've seen a similar temporal oddity with following type of code:
Piece {
id: piece
...
states: State {
name: "moved";
PropertyChanges { target: piece; x: nX; y: nY;
restoreEntryValues: false }
}
}
The if in javascript if I have Piece A and B and do
A.state = 'moved'
B.state = 'moved'
sometimes B moves before A.
Cheers,
Harri
