Question

Gravity simulation?

So I'm trying to make two objects attract towards each other using Newton equation of gravity, but I have no idea how to code this. If someone could make a little demo I can understand by reading the code.

    I'm trying to make one... Newton's gravity equation helps a lot, combined with some trig.

    Oh, cool! Thanks a lot. I might use this in my Orbit game actually.

    I never knew Newton's laws and other scientific laws can work in programming! :0

    Well many laws use equations, and math uses equations. Programming also uses equations. I have the gravity equation set, but my problem right now is working with Newton's laws of motion (an object in motion currently DOES NOT stay in motion), and direction never changes. But I'm working on it. Just gotta find the proper math.

    I'm actually the top student in my math class (I can do calculus), but I'm not the best when it comes to programming (and yet I made a 3D engine. I'm still not awesome tho). How's about you let me fiddle around with your project?

    I'd prefer to try to do it on my own. I feel like I'm at least acceptable (though I'm not quite to the higher points in math, like calculus) and I'm close enough that I could make it work myself. If I can't then I'll definitely give it to you, but I don't feel it's at that point yet.

    That's totally okay! Take your time. Btw is the program going to have touch screen support? Like, you could tap on the screen to make a planet, or drag while still pressing to give it speed.

    Yeah, though right now I'm working on the physics rather than the UI, though it will not be difficult after that.

    Mkay, here: Two circles will bounce around the screen, and will be attracted to each other using realistic planetary physics.

    By looking at the paths you can tell the precision isnt perfect (they wobble a bit) But they do attract each other the closer they are to each other
