Good answer. Thanks for the suggestion!

comment Libgdx: Am I abusing Vector2? Is there a better way to do my position updates and rendering?
@bobobobo: Right now I'm just using ShapeRenderer to draw raw lines. Later I'm planning to do something like rendering sprite batches or something, but this is my first graphics project, so I'm still just learning. Right now I'm just focusing on the simulation side of things.

comment Libgdx: Am I abusing Vector2? Is there a better way to do my position updates and rendering?
Performance is just fine on my desktop, but on the phone it's abysmal. Like 4fps. I understand that this is an inherently (or rather in-HAIR-ently! heh) intensive task, simulating hundreds of particles. But I'm just wondering if there's a better way. As it is, all the Vector2.cpy() calls are all instantiating new objects, which I'm guessing is impacting performance a great deal. Maybe I could save some time by caching the values, but I'm wondering if Libgdx exposes something "closer to the metal" which is much faster.

Wow! This is very in depth. Thanks so much, I hope you had as much fun writing it as I'm expecting to have messing with it! You rock!

comment How can I protect my save data from casual hacking?
While what you're saying is true, I think the author is aware that a determined hacker could probably still get at it, since he explicitly asked for a way to prevent "casual hacking". :-\

comment Why is my velocity decaying?
@Olhovsky: I'm still confused. From the article: "Euler integration is the most basic of numerical integration techniques. It is only 100% accurate if the rate of change is constant over the timestep." Isn't my rate of change here constant, since I never change my gravity?

Thanks again for your help. I'm going to have to read the article you mentioned tomorrow, since I've been staring at this long enough that I'm turning into a bit of a zombie myself! For now I'm off to bed. Thanks so much for your help!

comment Why is my velocity decaying?
I was expecting to have to add the effect in myself, and was just disconcerted when it happened by way of error.
