Simple Motor Vehicle Acceleration Function Thanks for the vote of confidence ;) Which of those functions is most realistic with respect to real cars? 1, 2 and 4 all have a very steep decline, is that what actually happens? (Not to say that I am looking for realism per-se, just curious) |

Creating an unbiased deterministic collision resolution order @JohnMcDonald, Actually, I'm doing: for each object in x-order: for each object with a higher x-coordinate (sweep-and-prune) :) |

Creating an unbiased deterministic collision resolution order True, so it's actually a tiny bit more complicated, I check for swapped versions of the pair too: if (o1, o2) not in collided: collided.add((o2,o1)). |

Creating an unbiased deterministic collision resolution order The problem with that is that each collided tuple (object1, object2) has to be identical, so that I can rely on Python's set() to keep only unique pairs (I only want to notify each pair once ). Adding tuple = (random(), object1, object2) would indeed be a solution, but then collided.add(tuple) would no longer preserve uniqueness of the list. |

Creating an unbiased deterministic collision resolution order I could use a sort key, the problem is that I'm using Python's set() to make sure each pair is only added once to the collided set, adding a sort key would break that behavior. |

Creating an unbiased deterministic collision resolution order So your suggestion is to shuffle the collision list, but in a deterministic way? I think the problem is that the collision list is in a nondeterministic order to begin with (because it's a Python set), so I actually need to explicitly sort it based on some property. |

Creating an unbiased deterministic collision resolution order This is what I ended up doing. I hadn't even thought about the hashes being unfair too, so I'll do as you suggest and randomize each frame. |
