Simple 2D hair simulation/manipulation 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! |

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". :-\ |

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? |

Why is my velocity decaying? 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! |

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. |

Why is my velocity decaying? No, I actually eventually wanted them to do exactly what they're doing now, but with an explicit decay specified by myself, not some arbitrary integration error. :-\ So it's doing what I want for now, I just didn't expect it because I was expecting it to behave like a classical newtonian system. |

Why is my velocity decaying? Awesome, thanks - appreciate the time! I'll go ahead and mark this as answered until I'm more smarter about Euler and Verlet! Thanks again. |

Why is my velocity decaying? Hmmm, but even with Newtonian physics, there isn't any explicit decay in motion. If a rubber ball were to bounce with perfect efficiency (nothing lost to heat or rotation), wouldn't it bounce forever? Since I'm just flipping the vector, I would expect it to be a "perfect" bounce, and it should bounce all the way back up to its initial height before dropping again. |
