Changing Colors in Celestia

Post #1by FarGetaNik » 22.08.2016, 09:18

I know there are several topics here on the forum to cover some of this, but this doesn't fit well into any of these. I have multiple questions.

How to change the deafault colors of orbits (and labels)? I think the default colors are too bright and confuse me when to much orbits are rendered. I've selected darker tones for minor objects.
For orbits, I know there is a ssc command:

Code: Select all

OrbitColor   [ 0 0.3 1 ]

But I'd prefer to change the default and don't have to worry about editing every single object in the solar system.

As stated here: http://celestiaproject.net/forum/viewtopic.php?t=11607 it is possible to change the default via scripting. I added the commands to my start.cel script, but it gives me an error: Bad parameter list. It seems to work with a seperate .celx script, but changes are not permanent.

Which brings me to my next problem: How to tell Celestia to launch via start.cel script? When clicking on celestia.exe it loads it's default script, even though I edited start.cel. It get's annoying to start Celestia via script.

Finally, I have to say that star colors seem unrealistic to me (especially M type stars) and it would be nice to change their defaults as well. But this might be a topic for a new version of Celestia...

It would be fantastic, if the GUI gave more flexible options to users.

OrbitColor need a CELX script, not the CEL script. You can switch from CEL to CELX through "celestia.cfg" at string InitScript.

Code: Select all

InitScript "start.celx"
...


Within this new script then you can insert the CEL commands.
Never at rest.

Which brings me back to the problem that Celestia seems to ignore the start script and launches it default no matter what I do with the script.

Could you be more specific about how the script should look like? I can't combine the start.cel skript and the color parameters for the .celx script in a way Celestia doesn't crash at launch. Sorry I'm a complete noob in scripting.

My start.cel script looks like this:

Code: Select all

{
  select {object "Sol"}
  goto   {time 3.0 distance 6000}
  gotolonglat { time 3 distance 3000 longitude 0 latitude 45 }
  wait   {duration 3.0}

  print  {text "Welcome to Celestia!"  row -3  column 1  duration 3}
  wait   {duration 3.0}
}

How to insert the color parameters in a .celx script while maintatining these commands?

OK I solved this problem (kinda...) when selecting a different script name in the config, Celestia seems to use it instead it's default.

I see your location is Germany.
If you run Celestia in German the initscript is not the one which is in the Celestia directory but the one in the celestia\locale folder.

Il you set

Code: Select all

InitScript "start.celx"

and your local is "de" then the file to edit is
celestia/locale/start_de.celx

Here is a way to include the previous CEL instructions in your new start.cel

Code: Select all

-- start.celx

function CEL(source)
   local script = celestia:createcelscript(source)
   while script:tick() do
      wait(0)
   end
end

CEL([[
{
# ... Beginning of standard CEL script
# ***** REPLACE THIS LINE WITH THE CONTENT OF YOUR USUAL START.CEL FILE *****
# End of standard CEL script...
}
]])

CELX instructions HERE

-- end of the celx script

Ah that's the reason! Thanks for pointing this out, maybe I'll use the english/deafult version of Celestia for the future... that is if I figure out how :think:

And thanks a lot for your help, it works now :smile:

This is the start.celx I use. Note that there are set in some add-ons you couldn't have. I've left them just to show some procedure about how to show/hide add-ons through shortcut keys when they are loaded at Celestia's loading. The .ssc of all the specified add-ons must have the propriety Visible false in order to be hidden at start.
Please: do remove all the lines between the commented out "start Magnetic.../end Magnetic..." or add the yours. The keyhandlers section set your custom CTRL+key. The CEL commands of the default start.cel are merged like written. As at is, the script move the observer at long 0. lat 0., so please do change it at your wish. The CEL section is editable as usual.

Code: Select all

-- start.celx

local obs = celestia:getobserver()

obs:setlocationflags

#                                                                           *

#          like pressing the "G" key on the keyboard. The time parameter    *
#          defines how many seconds it should take to travel there. The     *
#          distance parameter defines how far away from the object to be    *
#          positioned, in units of the object's radius, plus 1. For         *
#          example, if the object's radius is 10000 km, and you specify     *

#          Celestia to wait for 3 seconds while the goto takes place (for   *
#          3 seconds). The duration parameter value is normally the same    *
#          as the time parameter in the goto command. However, there are    *

#          command after it, that waits for another 3 seconds. It's all     *
#          just a matter of timing. The goto command allows us to display   *

#          you to remain in a stationary, or geosynchronous orbit above     *
#          the selected object.                                             *
#                                                                           *
#   print: Tells Celestia to display (print) some text on the screen. The   *
#          text parameter defines the text to be displayed. The row         *
#          parameter defines how many rows from the bottom of the window to *
#          start displaying the text at. The column parameter defines how   *
#          many columns from the left edge of the window to start           *
#          displaying the text. The duration parameter defines how many     *

maybe I'll use the english/deafult version of Celestia for the future... that is if I figure out how :think:

If you are running Celestia in Windows
You can launch it with a very little .bat file.

Make file calle celestia-en.bat in your celestia main file with this content

Code: Select all

set lang=en
start celestia.exe


Lauch Celestia with this celestia-en.bat instead of celestia.exe.

That's all.

That also worked fine, with my now modified config it also runs my costom script! :smile: Only the lua toolbar remains german, but that is not dramatic. Would still be nice to launch it with the .exe... Celestia automatically chooses it's location right? I'm not sure if I ever set it to german manually.

Fenerit, it will take some time to look at your script. Thanks in advance!

The file to edit is "config.lua" in the celestia\scripts\lua_edu_tools directory
This configuration files allows to custom many things int lua_edu_tool.
(see the language setup)

By default celestia use the local of the computer, but you can set it in any language you want.

Is there anything I can change about its configuration to tell it always to use english? The .bat file has no permanent effect. It's not that important, since I don't need it to always be english.

You should delete the main "locale" folder; this will set english by default. Mind to move your new start.celx to Celestia's root.

If I understand you correctly. all you want to do is run a customized version of the initscript?

In that case, it's very simple. The thing to realize is that the script itself can have any name you like, and can be anywhere on your system --- you just have to specify it's exact location and name in celestia.cfg using the syntax:

Code: Select all

  InitScript  "<filepath>/<filename>.cel"
eg. Replace:

Code: Select all

  InitScript  "start.cel"
with something like this:

Code: Select all

  InitScript  "C:/MyCelestiaScripts/MyCustomStartScript.cel"
There is absolutely no need to abandon your German locale, or run BAT files in order to achieve this.

In another example, I have personally not used celestia's default demo script for many years, but instead have found it more useful to re-purpose the "D" key to instantly set the FOV to 45 degrees, with this line in celestia.cfg:

Code: Select all

  DemoScript  "C:/MyCelestiaScripts/FOV45.cel"

That was one issue, which I already solved. I wasn't aware that Celestia prefers the german locale over the deafult start-script in the main folder. Also, it is useful to have access to the english version of Celestia.

That is actually a good advice! I hate it when I accidently hit D and find all my settings overridden :fie:

I use the "d" key to gotolonglat the observer at my coordinates; for all objects. :razz:
