Re: r^-5 "Orbital Decay"?

That's no coincidence (well, the PI thing is) -- the actual equation for a circular orbit is: speed = sqrt(G*M/d) (Assuming the asteroid has negligible mass, which it does.) For the basic inverse-square law, the G (gravitational constant) in the simulation is 1. The Mass of your star is 1000. So the...

Re: Calling all Suggestions

Showing off gravity wells is a neat idea. Even if it'd be too slow to render those *all* the time, maybe I could add it as a snapshot-thing. It's only an option when the world is paused, say. I also really want to show off Lagrange points. Showing a snapshot of the wells would do that, for starters....

Re: This weird level I made

Man, that's a pretty dastardly level to try and get perfect on. I'm down to 43, though. I'd guess my strategy is similar to your method, using the right-most two columns pretty exclusively. When we're ready (and I doubt 43 is perfect, still), I can always plug it into the 'solver'. Though I get the ...

Re: This weird level I made

Phew, I got it down to 52 moves, but I'm sure we're still far from perfect.

Re: Welcome!

Haha, yeah, announcement or not, you managed to find this within an hour of me posting it. Well done, ARP!

As to your confusion, I'll certainly be posting this week about it, but I wanted to get everything in place and give it a little test run first.

Re: The List

I was bummed that (not having a PC) I couldn't play the Stranger Loop *before*. But now that I see that whacked-out diagram you drew, I'm *really* bummed! Gotta see if I can mooch off a PC-owning friend. Seems brain-tingling.

Yeah, Robly, it took you a whole 24 hours to stumble across the forum? You must be losing your touch! ;)

Re: Great Level Design and the Artistic expression of maths

I really enjoyed your explanation of the Doppler Shift puzzle (~minute 28). It resonated with me, and reminded me of my methods. If you make a simulation with enough fidelity (be it a relativistic game engine, or the geometry and motion of bouncing balls), there are going to be some neat behaviors t...

Re: r^-5 "Orbital Decay"?

Oh, that's great! You've discovered an interesting fact about these force laws. It was only recently I added in the option to go as low as r^-5 force (before the minimum was r^-3). When I made the change, I noticed the same behavior. In fact, at the time, it was even worse... I couldn't get an aster...
