Help with creating Mods and Addons

PlutonianEmpire · 14 Feb 2018 17:40

Ive done it manually before, and Notepad++ and its search/replace feature has been a huge help. However, it is still a huge, tedious pain to do so, because Celestia SSC regularly uses some parameters for more than one function, and so after find/replace, you'd find two SE parameters with the same function but different numbers, causing the SC not not work in SE. I don't have the skillset to create a conversion utility, so it'll have to be someone else who does it, if they're willing.

has anyone got any tips on making star systems in a different galaxy? the slightest of errors in the RA/D puts the system off by millions of light years.

Maybe, just maybe you could start with making your own galaxy, and adding a star to it won't be off by much. I haven't tried that myself though yet.

and thats exactly why we cant place stars any farther than the magellanic clouds, SE isnt accurate enough at such distances yet

I recently decided to make a new, clean installation of Space Engine. I did this and applied the eclipse patch to it, then proceeded to copy my addons from my current, not so clean, installation of SE. I put Tabby's Star in the addons folder and it shows up in the F3 menu in the game (twice actually), but when I click Go To, I get Object Not Found.

How do I fix this?

Thank y ou.

I put Tabby's Star in the addons folder and it shows up in the F3 menu in the game (twice actually), but when I click Go To, I get Object Not Found

I don't have the "Object not found" error, but the reason why the star shows up twice in the object finder is in the manual:

Important note: the Star tag in the planets catalog and the StarBarycenter tag in the stars catalog must have different names. I.e. if the star has the name “Hole”, then the barycenter should be named “Hole system” or “Hole bar” or something like that. When creating an addon with some real star, which has multiple designations in the astronomical catalogs, it’s a good practice to give one to the StarBarycenter, and the rest to the Star.

So you can't give identical names to the starbarycenter in /stars and the star in /planets. Leave KIC 8462852 for StarBarycenter name, and the rest to the Star name:

StarBarycenter "KIC 8462852"

Star    "Tabby's Star/Boyajian's Star/Ekkentius"

If you still have the "Object not found" error, please attach here your se.log

I made the suggested mods and ran SE again. Tabby's Star still shows up twice in the list and still won't load. I attached the modded PAK and the current log.

Thanks again.

edit: I downloaded another Tabby's Star PAK file from this site and it shows up properly.

Thanks for the help!

from your se.log:

[MT] "addons/Tabby's Star.pak/catalogs/stars/KIC 8462852.sc" line 1: ERROR: Opening bracket '{' expected in the tag 'StarBarycenter'

[MT] ERROR: Recursive link detected: object "KIC 8462852/Tabby's Star/Boyajian's Star/Ekkentius" have itself as a parent

indeed it looks like you switched modifications in files, in catalogs\stars:

StarBarycenter "KIC 8462852"

Star "Tabby's Star/Boyajian's Star/Ekkentius"             <<----- cut this line and....
{
    RA      20.15457
    Dec     44.272461

in catalogs\planets:

Star "KIC 8462852/Tabby's Star/Boyajian's Star/Ekkentius" <<---- ...paste it here in substitution
{
    ParentBody     "KIC 8462852"   
    Class           "F3 V"
    Luminosity      7.7983

the main thing is always looking for "ERROR" lines in se.log when you test a new mod.

I am currently in the process of finishing up a solar system I have created. Everything else here is done except for the barycenters for various planets and stars. If someone could do them or teach me that would be great.

Barycenter's needed:

Adalet - Rienna
Lerapoda - Mariponia
Trepe - Freste
Portarten - Extotas
Onuris - Rin

The 3 brown dwarf stars should orbit the common barycenter of Rienna and Adalet.

Starlight Glimmer, if you see Quadruble by JackDole, you will see a example, so with your custom name for the first :

Barycenter "Adalet - Rienna"
{
    ParentBody  "B189"
    
    Orbit
    {
        SemiMajorAxis   0.44444444 //AU
        Period          0.60858062 //Earth’s year
        Eccentricity    0.035029        // Random value (Circular/Elipse : 0 to 1)
        Inclination     4.82284         // Random value (in degree (-360 to 360))
        AscendingNode   135.174108      // Random value (in degree (-360 to 360))
        ArgOfPericenter 65.7105         // Random value (in degree (-360 to 360))
        MeanAnomaly     0.0 //(in degree (-360 to 360))
    }
}

And generally for me the opposite star if is 2 main aster around the barycenter, I put +180 in MeanAnomaly or ArgOfPericenter +180 if the other is 0.
Else, I made for you. You can edit if you want because it is your mod

Ran into a weird issue when making a new ship. Applying its normal map caused the model to be illuminated from the opposite direction of the nearest star. The texture is ripped from another game, so maybe it's conflicting with SE somehow, but how can I fix this?

It looks very good. Thank you very much, it sure has helped alot with the designing of this solar system!

I'm having trouble adding a accretion disk to a black hole I made it doesn't show up for some reason

[moved on this topic since it's a request for help about mod/addon]
You didn't specify where you placed your code. I'm assuming you placed this code under addons\catalogs\planets\
If you look at your SE.log and your console window ("~" key on US keyboard) you will see the message:

ERROR: Recursive link detected: object "blackhole" have itself as a parent

This happened because you used the same name of the object in ParentBody.
The manual says you must have a ParentBody with a different name in another script file, placed under addons\catalogs\stars, in your case for example a simple script with coordinates only it's enough:

StarBarycenter "blackhole1"
{
 RA       09 31 14  // right ascension
 Dec      64 16 38  // declination
 Dist     250.0     // distance from the Sun
}

and first lines of your original code then become:

Star "blackhole"
{
 ParentBody     "blackhole1"

Check always for errors your SE.log and the console window.
