No animation with text?

Hi,
GRIN-based animation works great but translator does not seem working if "feature fixed_image" is replaced with "feature text"?
Can you please clarify?

No, that should work fine. The Translator mode works by
calling java.awt.Graphics.translate(int, int) and then
painting its child; it doesn't make any difference what
the child is.
Can you make a small, stand-alone GRIN text file that
reproduces what you're seeing? Perhaps one with two
segments, one where a fixed_image is translated, and
a second one where a text feature is translated.

Thanks, Bill.
In the bookmenu sample, the menu animation disappeared if I replaced
"feature fixed_image F:MainMenu.Play.Normal 450 880
"Graphics/Menu/Play_N.png" ;"
with
"feature text F:MainMenu.Play.Normal 450 880
{ "Play" }
Lisa plain 60 { { 255 0 0 255 } } ;"
(F:MainMenu.Play.Selected and F:MainMenu.Play.Activated were changed accordingly too.)
I also tried to change all four menu-items (play, setup, scene and bonus) from fixed_image to text, there was no animation either.
BTW, I temporarily removed frame skipping in runAnimationLoop in the ClockBasedEngine so that animation can always be seen regardless running time.

Can you reproduce the behavior with a small, stand-alone
example that I could run in grinview directly?
One possibility is that you might be playing this on a PC
player -- I've seen inconsistencies in font rendering
on at least one PC player. Are you sure the problem is
related to the translation, and not just the font rendering?
Cheers,
Bill

Following is small example that can reproduce the problem.
I am using CinePlayer on PC but I saw similar behavior on PS3. I'll double check this simplified example on PS3.
Thanks,

I just confirmed that the above example had same behavior on PS3. That is, animation with image worked fine but animation with text did not work. .

OK... A really minimal example would have made the problem
come out more clearly, but here's the deal: The example you
gave is using the old, deprecated "linear" style of specifying
coordinates to the translator_model. I guess that's because
you took the old example of the cookbook menu, which was written
before the new, better "linear-relative" style was invented.
"linear" is problematic with some feature subtypes; it was kept
for backwards compatibility (e.g. with old examples), but the
GRIN compiler issues a warning recommending a switch to linear-relative,
because it's dangerous.
I have a pending putback that significantly strengthens the deprecation
warning, and also changes the compiler to recognize that "linear"
and text features don't mix. With the putback, your example will
fail, with this message:
WARNING: Deprecated non-relative linear interpolation;
consider using linear-relative instead.
Note that "linear" isn't guaranteed to work with all feature types.
For example, it's known that it doesn't work with the text feature.
==> Dangerous usage occurs on line 49

Great! linear-relative works like a charm for both image and text.
