> There are plenty reasons that it might be true that no games that you know of shipped with a robust real-time solver for sword-sword collisions other than computational complexity.
This is the kind of comment that makes me just want to skip HN altogether. Why on earth are you arguing this at all — the counter to a point I never made — and why are you arguing from a position of ignorance like it makes you smarter than me?
You don’t have to pull an opinion out of your ass here. Just try it, the way my sibling poster has. This is a mathematically hard problem, and it will constrain your game design, and I think that’s really interesting.
HN can definitely be annoying when commenters act like they know more than they do. No question about it. But please don't let it trigger you into lashing out, which only makes the thread worse. Instead, remember that the vast majority of readers are here to learn, and if you know more, sharing some of what you know, or some of your experience, is really helpful to them.
p.s. On another note, can you please stop creating accounts for every few comments you post? We ban accounts that do that. This is in the site guidelines too. HN is a community. Users needn't use their real name, but do need some identity for others to relate to. Otherwise we may as well have no usernames and no community, and that would be a different kind of forum. https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme...
Is there a reason hn admins can't send direct messages to users, as opposed to calling them out publicly for things like this? I suppose doing it this way is probably more effective in changing behavior.
I just don't see how your observation (that you are not aware of any game that solves the problem well) leads to your conclusion (that its solution is computationally complex). I can see that there may be other lines of reasoning that support that conclusion, for example something pertaining to the algorithms and techniques involved, but I also see how other conclusions may be true given your observation.

You are reading way too much into my post. I am arguing from a position of ignorance, but under no pretense that it somehow makes me smarter than you. On the contrary, it seems like you are familiar with the problem, and I think that you may have made much more relevant observations than the one you posted, but because my post has already prompted a more detailed description of the problem and its potential solutions I don't have to wait through petty insults to hear about it.

You really don’t have to be a dick about it.
