Does anyone know of a script which follows the Voyager trajectories (using the available models etc.).

Thanks

Some time ago I wrote a script showing the flight of Voyager 2. In principle it worked fine, but I had some problems which I described in a previous post ( http://www.shatters.net/forum/viewtopic.php?t=1683&highlight=voyager+script&sid=c04115a819b237809de8380426c33518 ).
The script is a bit lengthy, and I have not tested it with 1.3.0 because I have the idea to re-develop it using Lua. If you are interested I can send it via eMail.

Thanks Volker. If you can be bothered sending your script please do. Here's an email address:

luckas@hotmail.com

Thanks

Try this one:

paul_luckas@hotmail.com

Thanks

Send it to [REDACTED] also ;-).

Howdy Volker,

Please, I too would like to see your script. There aren't many out there for downloading and learning.

Thank you!

PS. How do you guys code mailto: URLs here in the forums?

Huh?

Simply, we just write them down

)

mailto:x@y.com

It was plain text in the preview and also gets posted as plain text.

I tried the URL button too, but it came out as plain text also.

Edited PS. HTML is disabled for me, if that's what you mean.

Volker,
I am another guykind to send it to:, interested by your script. Please be kind to send me at:

I didn't expect to see a "sendmetoo" chain here...

Why don't send it to CrookedScepter, so it's available to everyone?

don, I simply write just the mail address, and I have HTML off also.

meme@myemailserver.com (trap here for spammers, hehehe)

Don't use brackets, parenthesis, nor mailto: headers. Just only the address (or at least spaces before and after it).

Could you please copy-paste your script as a reply in this thread, so that everyone can enjoy it without giving away an email address (spam hits hard these days )

Thank you very much!

Thank you jamarsa. Figured there would need to be some code somewhere -- guess I was making it harder than it is (sigh).

I think "space before and after" was the clincher.

PS. I too think that copy-paste posting the script (using the Code button) would be a GREAT idea. No matter how long it is, we can all copy and paste it ourselves.

thats why text editors have a "select all" button

Ok, ok ...
Sorry, I was not aware of the spam problem. I was only afraid of boring with 200 loc showing repeatedly the same commands and working not perfectly anyway...
As I said in the previous post, the repeated sequence of timerate and wait commands only serves to vary the time lapse when approaching a planet, i.e. moving faster when far away, and (more or less smoothly) moving slower when in the near. However, the result is not totally reproducible, and I noticed that the script works better when run a second time (and all the textures are already loaded I guess).
Any better idea? My thoughts: It would be nice if the wait command could possibly be linked to the distance to a planet or to the Celestia clock ('wait until a specfic distance is reached' or 'wait until a specific julian date is reached').
Now here is my attempt of a Voyager script. I use the Voyager trajectories from http://www.shatters.net/~claurel/trajectories/ .

Thanks Volker!

That's pretty cool.

I used the Voyager files from Darkmiss: http://www.bt.homepage.btinternet.co.uk/Celestia.htm.

Thank you both!
