I can set up a stable orbit the hard way, trial and error right now (playing with density vs. momentum vs. distance from main gravity well) or I'm sure that I could figure out the mathematical to figure all of that out... but I'm looking into doing it the quick and dirty way... get close enough with option 1 (trial and error) and add some orbital correction scripts...
I'm looking at these basic functions to begin with...
Position (not sure how to use this, but I hope it'd get the roids cords)
&
MoveTo(x,y)
But I'd have to know what quadrant the the roid is in, or every time it passed either axis it would jump... so i need a 'when x=0 check if y is positive. If yes, MoveTo(0,600)), else MoveTo(0,-6000) and a similar y check... o.O
