This is a much improved version of a game I submitted earlier, but got shot down because I used 1 sprite that came with GM. So I changed the sprite. And I improved the gravity equation to get more accurate orbits and more efficient path tracking. To start, click on Make Planet, then place the planet, then select a speed and direction for a new sattelite, hit Make New and place it on the field. To get rid of a planet, right click it, to get rid of all satellites, click Destry Sattelite. To start orbit tracking, left click the Orbit Tracking button, and right click it to stop the tracking, since it will eventually slow down the program, stopping tracking will fix it. I will update this as soon as I can figure out how to use the actual Universal Law of Gravitation and implement atmospheric friciton effects. I'll probably fix the graphics at a future point in time as well. It is possible to make a stable figure 8 type orbit, but introducing a third planet into the system will make it unstable. Oh, and this is registed only, and the screenshots are old too, I'll update 'em eventually.
