I would like to ask for a mod to add a new tab in the system desginer input for planets it shoudl changed the parameters Position (X/Y) and Velocity (Vx/Vy) for something more "physically treatable" Here is the actual tab display: The main parameters are: Minimum distance (a.k.a. Perihelion) Maximum distance (a.k.a. Aphelion) Elipse Tilt the minimum distance will be referenced as rp the maximum distance will be referenced as ra the elipse tilt will be referenced as theta. Theta must be entered in degrees, and dont forget to convert to radians, as most internal pre-built functions use radians argument The tilt follows the trigonometric referential: 0 at the right, 90 at the top, 180 at the left and 270 at the bottom. GM is a reference to the gravity constant * sun mass and, meanwhile, its value is 500000000 (in engineering: 5e8, in scientific: 5*10^8) I believe (not so sure), that the game can only generate the orbit with the X and Y informations, so the mod must also do some internal calculations and fill these spots for the game engine the formulas to make these transformations are: (my idea is always starting at aphelion) Position X: X=cos(theta)*ra Position Y: Y=sin(theta)*ra Velocity X: Vx=-sin(theta)*sqrt(2*GM*rp/(ra*(rp+ra))) Velocity Y: Vy=cos(theta)*sqrt(2*GM*rp/(ra*(rp+ra))) I hope I made clear enough, feel free to make any questions EDIT: changed one formula that I screwed up with the minus sign
clicking and dragging is just too manual, and may not guarantee to reach desired values and when you have more than one planet, click and drag will almost never have 2 planets with the same orbit line, which means they are more likely to cross each other eventually
