Moving my old add-ons

[Tegmine]

First, it's nice to see that someone has picked up the baton and has continued running with Celestia. I haven't done too much with it for a while, rather, just focusing on adulting with odd bits of worldbuilding to pass the time.

That said, I recently got Celestia working for my laptop, which is running Ubuntu 18.04. I was able to get Celestia downloaded and installed, however, I do have a slight problem...I've got all these add-ons I would like to incorporate. I thought I would be able to just move the files from point a to point b...WRONG! The new location will not let me move, copy, paste, NADA. A little frustrating, but I'm sure any Linux experts out there would be able to at least point me in the right direction as to what I need to do.

Many Thanks,

This is expected situation for a proper designed OS: not to allow writing to every place a user may want. If you are with 1.6 version, you can always use sudo to copy files. With 1.7 you can create minimal ~/.celestia.cfg and define your extras directories in it.

[Anthony_B_Russo10]

Or you could try and open your file manager as a Root user allowing to add files to the Celestia directory.

[Tegmine]

It's the 1.61 version. Not super proficient with the terminal commands, but I am GREAT at following well-written instructions.
As far as accessing the root, I'm not even sure how to do that. "Open as root" is not an option on my file manager.


Thanks

What is the name of your File Manager.

[Tegmine]

Nautilus, also known as "Files"

Got it figured out....Thanks for your help. I just needed to be pointed in the right direction!

You're welcome.

New wrinkle; my old addons work well, and I even was able to edit one of them. Still works fine. SO, I tried made a new add-on from my notebook of systems. (I took up worldbuilding when I couldn't run Celestia). The planets show up around the star, but NO TEXTURES!


I have:
Edited the .ssc through System Maker (ancient program that still works on my even more ancient desktop)
Edited the .ssc on my laptop
Changed the file and texture names to lowercase. The funny thing is, at least one of my older addons has upper case, numbers, etc. in the texture names and they show up without a problem...WHAT GIVES?

Here's the .ssc for your perusal....

I have compared this side-by-side with a working addon. I could find NO differences in it. Maybe some fresh eyes can. As always, I thank you for your help!

Check your Celestia's console (press tilde ~) to see debug messages and errors.

[LukeCEL]

Just an idea. Are the textures inside the medres folder? In other words, have you made sure that the folder hierarchy looks something like this?

Code: Select all

xaph.ssc
[textures]
➥ [medres]
    ➥ xaph.png
    ➥ xeria2final.png
    ➥ xeria2spec.png
    ➥ geothermal.jpg
    ➥ xaphus.png

[Tegmine]

yeah. Everything is where it needs to be. Although, I just went through the normal means, not checking via terminal...which I don't know how to do.

Check your Celestia's console (press tilde ~) to see debug messages and errors.

How would I do that, exactly? I know how to do some things with Linux terminal, but a lot of the background stuff and codes I don't. Thanks

PS: Yes, I freely reveal my ignorance.

[SevenSpheres]

It has nothing to do with the Linux terminal. Just press the ~ key while in Celestia; you should see something like this.

[selden]

Celestia's "console" is available only within Celestia's own window. While Celestia is running, type a tilde (~) to see it and use the keyboard's up/down arrow-keys to navigate up and down in it. Tilde is Shift-` at the upper left corner of many keyboards. If you have many addons, you might need to increase the number of console lines which is down at the bottom of celestia.cfg. In other words, you might want to change

Code: Select all

#------------------------------------------------------------------------
# The number of rows in the debug log (displayable onscreen by pressing
# the ~ (tilde). The default log size is 200.
#------------------------------------------------------------------------
# LogSize 1000

I took a couple of screenies from the two latest ones I've done

Here's one:
download/file.php?mode=view&id=7920

Here's two
Screenshot from 2020-05-31 11-25-46.png

As you can see in either, there is an error loading the files; I only put my textures into a file named 'medres' which is in a folder named 'textures' which is in a folder for that particular add-on.

Most puzzling!
I tried adding to the cfg file that Selden suggested, but it didn't seem to change anything.
Thank you for your continued patience.

If you are willing to provide the contents of your .ssc file plus a listing of the associated files, that might help someone to notice the problem.

Specifically, to generate the file listing, cd to the directory where your .ssc is located and type the command

Code: Select all

ls -lR

that'll list the files in the current directory and all of its subdirectories. My suspicion is that there's a typo in the texture image's name or it's not where you think it is.

Perhaps the png file is not a real png file.

Try with an another png file.

[selden]

One problem that I see is that the spelling of the directory name is incorrect: it should be "textures" not "Textures". Linux distinguishes between upper and lower case. I'm surprised you didn't get lots of other errors about missing image files.

Edited to add:
The lack of error messages probably is because you didn't "goto" other planets, so it didn't try to load their surface texture images.

[Tegmine]

That was it...a capital T on my texture file...

Thanks...now I can get back to making my addons.

[selden]

It's the kind of mistake anyone can make, and it's hard to notice if you aren't looking for it.

Have fun!
