Title: Huge problems with asteroid belts :(
Post by: Andreas on November 08, 2008, 10:54:31 AM
Well i want an asteroidbelt around my systems central star Eta Carinae
I placed it into the file (i stole it from the retrograde system file :P )
But now the asteroid belt is around Uranus!
I added the file here, maybe somebody can fix it?

You don't need <apperance> just put the apearance in the <Object>. And some misspellings. I can't find your asteroid belt problem

Look i did write that into the file:
<System>
  <Body>
    <Name>Eta Carinae</Name>
    <Object>Sun</Object>
    <Appearance>Sun</Appearance>
    <Mass>2386920004861.35</Mass>
    <Density>0.000331531562362774</Density>
    <Diameter>111199999.999999</Diameter>
    <PositionX>-1828588522.56687</PositionX>
    <PositionY>-84130649.7176691</PositionY>
    <PositionZ>-54975270.6927182</PositionZ>
    <VelocityX>-0.000602008613617416</VelocityX>
    <VelocityY>0.00161890506912887</VelocityY>
    <VelocityZ>0.000345677627568305</VelocityZ>
    <Settings>gravity=1;particles=asteroids</Settings>

But the belt don´t orbit the star, it orbit a little planet.
Here i did make a screenshot

Andreas,

The reason that the asteroids appear around Uranus is because currently they are hard coded to appear around the 0,0,0 point.

I'll add some additional options for an improved asteroid belt that will solve your problem in the next release. I'll also make it easier to recenter any body to the 0,0,0 point.

And your system is impressive. How did you put it together?

I made the massive Star. Then i made the big planets. Also i placed massive moons around the planets and let explode them. So i gave the pieces names and changed a bit their mass and appeareance.

I deleted the asteroid belt at the moment, because i don´t want one around Uranus ha ha

Btw, is it possible to change the colour of the Star?

I want it more Blue, because Eta Carinae is a very very massive star.

You can change the color of planets by adding <Color> to the system file:

Hex value:
<Color>FF0000</Color>

RGB values (0-255):
<Color>255,0,0</Color>

Color Name (only a few color names work):
<Color>red</Color>

All 3 examples make the object pure red.


Although for objects with a large enough mass to be a star the color is overridden. Currently <Color> will only work for planets but not for stars. I'll fix this too. Thanks for pointing it out.


I'll also add Eta Carinae to the star database (I don't think it's there).
