Hi,
Thanks to a few people giving me good hints I finally got those
dist-scale/billboard/translate animations to work (reading the
donauturn.xml example was very usefull).
It was a try and guess exercise (because of the lack of docs) but it
worked. Now I have three billboard lights which scale according to an
interpolation table.
That's the point now, there's some syntax in the dist-scale section I do
not fully understand.
The line <dep alias="../../../../params/light"/> seems to be related to
the lines:
<params>
<light>1</light>
</params>
I interpret this as setting a variable called "light" and reading that
value with alias="../../../../params/light"
Well, I'd like to know more about that particular path-like string (the
"../../../../" before params/light) in order to use it in a correct
manner in the future. How do I have to read that? It looks like a
property tree path to traverse? If it is, what kind of property tree is
that? What's the root? I don't find it in FG property browser.
Second point is I used the following syntax (from donauturm example) in
order to get the translation of the poly light:
<offset-m>67.5</offset-m>
<axis>
<z>0.20</z>
<x>-0.62</x>
<y>-0.17</y>
</axis>
Is that fully interchangable with:
<offsets>
<x-offset-m>22.0</x-offset-m>
<y-offset-m>-15.0</y-offset-m>
<z-offset-m>-62.0</z-offset-m>
</offsets>
Are there any difference in the way that's used in the animation code?
cheers,
Roberto
p.s. I changed the object and param names according to my 3d model but
the syntax is still the same as the donauturm example.
