OK. Here is another one to try out. It is a tour of the 9 planets and their moons. This was actually my first script, but it was very difficult to perfect - still working on it. I don't know how it will run in 1.3.0, so let me know, if you are using that version. I'm using pre11.

Leave lots of feedback - it's a great way to learn and improve.

Here it is -

Excellent...

Keep them coming, Christoria. Your doing all of the work, and I'm having all of the fun. I've just copied your script, and I'll let you know what happens on my clunker.

By the way, you can insert the script text as code if you want to (Like Don suggested to me for your Distances Script). See the "Code" button above the space in which you're editing your post.

Thanks *very* much for keeping me entertained. :D

Take care, Bob

Oops...

That was me Christoria.

Sorry, I forgot that I hadn't logged in yet. I just got so excited when I saw your new script, that I *had* to copy it and thank you for the effort.

Take care, Bob

Cool script. 8) This is a great way to see a tour the solar system for when I'm feeling so lazy, that even using my mouse is too much effort!

However I seem to have a lot more moons around the outer planets, than what you are describing. One major moon you have missed out is Neptune's Triton. Can you please add this to your tour?

Christoria,

Just so you know... The script worked fine under 1.3.0 with NO changes made to it. You've given me the basis for a more complete tour now though.

Sheesh! Just when I thought I could rest for a while. Now, I'm not going to be able to sleep until every moon, satellite, planet and asteroid is visited via my PC. :lol:

Thanks again, Bob

The tour-system.celx lua script visits all objects in the solar system, but it's a bit boring when you get to the outer planets... I should add a limit to the number of satellites visited.

Thanks for all of the comments.

TERRIER - Triton will be added. Sorry.

Bob - Thanks for the info on v1.3.0. I'd love to see your modified script of everything included.

Christophe - Thanks for the link. I'll try it later. I want to learn Lua next.

Thank you,

christoria

Howdy christoria,

Gee wiz, I got so caught up in the Sun-Planet size comparison script that I plumb missed this one! Sorry! :oops:

Not sure what the original looks like but your version is nice.

Some of the text is displayed a bit too fast for me though. And, you might want to define an FOV setting in the script, as it was probably written for an FOV of 45, instead of the current 25 (in 1.3.1 p11).

A challenge for you, if you feel up to it :D ...

After a moon is displayed, the script currently pans back to it's parent planet, which usually results in the moon no longer being displayed. My challenge to you would be to have the script keep the moon in view, maybe moving it aside slightly, and bring the planet into view, so that both are displayed at the same time.

What do you think? :)

-Don G.

In CVS (I don't know if it's in the latest pre-release) there is a new command that centers the selection while keeping the primary body at its current position, that is you orbit the primary body to bring the selection at the center of the screen.

For example, go to the Earth, off center it a bit making sure it lives the center of the screen free, select the moon and press SHIFT+C.

I don't think there is a script command for it yet.

don,

I'll give it a shot. Currently I'm making sure everything is perfect for a complete backup of Celestia. I'm finding I installed things too quickly and have doubles of some galaxies. I'm also adding some new ones like Andromeda with Selden's "Billboard" mesh. I'll certainly get to it soon, but unfortunately not today or tomorrow. Also, great job on the modified planets script. I didn't time it perfectly, but it seemed about ten minutes. Really great presentation in a quick little script.

By the way, to anyone interested in adding more galaxies or other things themselves, I highly recommend the "Billboard" mesh. It is so easy to use and all you really need is a hex editor and notepad - and of course some pictures.
Thank you,

christoria

Hi Christophe,

Yes, this function is in pre 11. However, sometimes it doesn't work, and I've not looked into exactly why yet, or made note of the circumstances.

You are correct, as is the case with many Celestia keystroke commands.

What would be really helpful, and could be used by both .cel and .celx scripting, would be a command to pass Celestia a keystroke combination (character, upper or lower case, Ctrl, Shift, etc.) via a script. This way, most new Celestia commands would instantly be available to scripting as well -- without the immediate need to code a command for either scripting language.

Obviously, things like data entry (Enter key), capturing an image or movie, etc. would be excluded, along with multiple target functions, like the one we are discussing (Shift+c). [Edited: Actually setframe could be used to select both objects.]

For example, one would use the existing select command to select an object, and then "send" a "g" keystroke to goto the object. Just a thought.

Hi christoria,

Great! There is certainly no urgency to it, it's just another learning experience to be taken slowly when you have the time and energy.

I've really wanted to play with the setposition, setorientation, rotate, orbit and other movement type commands, but just have not found the time <sigh>. If you end up using any of these, please keep notes about your experience and what you learn along the way, so I can add them to the Scripting Guide to help others too <smile>.

It is very easy for this to happen, if add-on creators call an object by different names -- their "M" number, the text description, etc. Sometimes, add-ons can get confusing if you're not an astronomer.


christoria wrote:I'm also adding some new ones like Andromeda with Selden's "Billboard" mesh.
I started playing with his write-up about billboards some time ago, but got into something else and never got back to it <frown>. There are soooo many FUN things to do in Celestia that it is like being a kid in a candy store! 8O :D

Thank you christoria. Couldn't (wouldn't) have done it without ya! :D And thanks to Bob also, for the more accurate distance values and spelling / grammer corrections. It was a good 3-way effort, yes?

I'm not much of a "creator" (thinking up new things), but when I come across something interesting like your script, that I can actually see in action, then the thinking comes alive as to how it might be different. Very strange, but that's me. :P

Yes, the new one runs between 10 and 11 minutes.

Ciao for now...

If you find a reproducible way where it fails let us know.

That's problematic because the keyboard command mapping is in a sorry state at the moment and is very likely to change. Relying on keystrokes in scripts would be likely to brake your scripts with futur versions of Celestia.

What is on the TODO list for the next version is a cleaner internal API to handle keystrokes that would allow easier integration of new commands in the script languages and even personnalized key mappings (think non-US keyboards).

Indeed - Sorry Bob. Thank you also for the time you've put into this. What a cool script it's become by now for everyone to see.
Thank you,

You can count on me. :wink:


Christophe wrote:That's problematic because the keyboard command mapping is in a sorry state at the moment and is very likely to change.
The thought behind my idea is to merely have the script parser catch non-allowed items and then format the keystroke it gets from the script to the format Celestia wants to see and simply pass it to Celestia's keystroke parser. This way, it would not be tied to any keystrokes themselves (except for the non-allowed items).

However, if the keystrokes themselves are going to change in the near future, then no, this would not work right now.

This will make a LOT of folks VERY HAPPY! :D

If keyboard-handling gets changed anyway: it would be nice if it were possible to pass keypresses through to a script. AFAICS currently not all keystrokes reach CelestiaCore::charEntered(), at least not in KDE, so there is no central place where they could be intercepted :?

Hey, no problem Christoria...

Don't be sorry for anything you've done here! You've added a great, free resource to the bag of fun that is Celestia. Keep 'em coming! :D
