I have a cel script that worked beautifully in version 1.5.1
The part that I used from Space opera to show the Milky way is the part that no longer works.
The Select object Milky Way doesn't work from a script on inside the the interface
the way the other script goes there doesn't work in 1.6 either. Not sure which build version of the 1.6 I have
Any help is appreciated.
Basically I want to go thorugh dark space get to the Milky Way at a resp[ectable distancle . orbit for a bit . then oof to the sun earth ... etc
Just nee the first part to work like it did in 1.5.1
Reason I want to use 1.6 is the ability to set lince colors and label colors . I want to show Lakota constellations in one color and when I switch to other Nations change the line colors and labels.

Hi elbertdee,

I copied your script shown the most obivious thing missing are the { } at the start and finish of the script, I guess you may have just left them off as you should have got an error message.
With the brackets the script seems to run OK in the latest SVN4645 version I have

hanks

That is just the snippet of the part that wasn't working.
I just tried the build I got last night. It says svn4679

and The first part still doesn't work as in 1.5.1
The Milky Way doesn't show up till starting toward the sun and then it just flys by.
in 1.5.1 it slowly appears and then Orbit then to the sun.
Here is just the Milky Way part that is the problem. Try running it in 1.5.1 and 1.6
It looks very different. Least with the version of 1.6 I have
If there is a version it will run in and have the setline and set label May I Please have the link.

Thanks

Elbert, I tried your script just now, in both 1.5.1 and 1.6 with svn4679, as your one.
It works without problems here, both give exactly the same results.
Sorry but I fear the problem is of yours.

May be the graphic card drivers?
Or some Celestia corrupted files?
I can only suggest you to try to install again the 1.6 with svn4679.
Good luck!
Bye

Andrea

Elbert,

I just now tried your script with both Celestia v1.5.1 and Celestia r4678 and both looked the same to me.

What environment are you running the svn version of Celestia in?
For example, if you simply copied the updated Celestia executable into the v1.5.1 directory, it can't work correctly. There have been incompatible changes in celestia.cfg and the names and locations of its catalog files.

Ok maybe that is it. 1.6 loads with the old config file and runs most everything just not that first part of the script.
Thanks for the info.
Is there away to get the whole thing for 1.6 ?

Thanks

My guess is that an official release candidate will be available within a month.
Until then, you'll have to download the files from sourceforge, either individually or using svn.

If you want to do it manually, you might try copying the entire v1.5.1 directory to a new location, and then downloading the new version of celestia.cfg and the files that it references from sourceforge at http://celestia.svn.sourceforge.net/vie ... g?view=log
and
http://celestia.svn.sourceforge.net/vie ... stia/data/

The procedure for using svn to download the files is described in the Celestia WikiBook at
http://en.wikibooks.org/wiki/Celestia/D ... 2_platform
