That bright orange blob actually sucks things towards it in a manner resembling gravity. All depends on the mass, the distance, etc. And yes I did have to break out my A-Level Physics text book to figure out how to do this - too many formulas. So if you have the XNA Game Studio Express Beta 2 then check it out. If not then wait till whenever the redistributable libraries come out (don’t ask). UPDATE: Actually it turns out there is a redistributable XNA framework out so anyone can try it! New download is here with the XNA stuff included.
It’s very basic, you can’t do much but it shows what you can achieve after a few days.

Any chance of fixing the zip file? Want to look at the source to your gravity calculation.
Yes it seems the zip is corrupt now. It has been a while since I touched this but if you would like the full source code from my repository I could provide that? No guarantee it would work with the latest XNA though.
I would really appreciate the full source from your repository. I saw it’s a while since you wrote this, but hoped you still have some code available.
You will be surprised how long I had to search to actually find a demo like the one that you provided here.
Thanks!
Yeh it’s funny I was searching for the same thing a few years ago and that’s how I wound up posting this. I have checked out the latest source and zipped it up here. Not sure what state it is in but the basic concept should be pretty clear. Let me know how you get on.
Thanks
Having a look at the gravity code and then try to implement it.
