Defining Planet/Space Location orbital properties:

• orbit = {
  • parent = {
    • type=<("space-location") or ("planet")>
    • name=<name of the planet it is orbiting e.g. "nauvis">
      }
  • polar = {<distance from parent>,<bearing from parent in radians>}
  • eccentricity = <default is 0 which means its a circular orbit, greater than 0 and below 1 means the orbit is elliptical>
  • periapsis = <bearing of the closest approach in radians, mandatory for elliptical orbits and pointless for circular orbits, the distance in the polar property is taken as the closest approach distance for elliptical orbits>
  • no_sprite = <basically doesnt draw on orbit if true and defaults to false>
  • sprite = <sprite shifted, scaled and placed in the starmap in order to make an orbit making moon orbits possible and even extra star systems! It may be layered or singular and a how should be in a gallery or MT-lib/graphics/orbits/orbit_image_tutorial.png (sorry for the bad drawing)>
  • sprite_scale = <what to scale the sprite by in the orbit for more fine tuning, default is 1 (no effect)>
    }

The following 4 are only definable for type="space-location":

• unlandable = <defaults to false, if true you wont be able to have a space route there or a space platform but the starmap_icon is placed on the starmap automatically>
• is_background = <defaults to false, if true the starmap_icon is taken as a sprite and will scale that by the provided magnitude, places on background>
• is_sprite = <defaults to false, if true the starmap_icon is taken as a sprite and will scale that by the provided magnitude, places on foreground>
• barycentre = <defaults to false, if true no location will register on the starmap, not even the icon. Useful for Binary orbits such as pluto & charon>
