I have noticed a substantial uptick in questions relating to practical implementation of physics in video game development. (Here is a search link for such questions.) Some of these appear to be homework related, some of them border on crowdsourcing. Just wondering what the thoughts of the community are on these sorts of questions.
I'm going to suggest some possible limits.
- We only answer questions about physics. Implementation questions go elsewhere. Likewise questions about software toolkits.
We only answer questions about real physics, but we include the various approximations that are common in physics teaching: neglecting friction, neglecting air resistance, linearizing nearly everything, simple impulse collisions, etc.
It is the asker's responsibility to identify the approximation regime they want to know about, and we don't advise them on how these decision will affect their implementation.
- We answer only about physics in the general sense and do not solve individual instances of problems--this is in keeping with out homework policy.
- We police these rigorously for duplicates, and identify those on the basis of the "Same answer?" criteria.
The ones asking for code are off topic and ought to be migrated to gamedev.se.
The ones which are just in the context of writing a game are generally on topic (flag if unsure).
BUT, the HW policy does apply to crowdsourcing questions like these. The HW policy is about the type of question, not the context in which it crops up. Thus, if it doesn't follow the HW policy, it ought to be closed (or migrated if possible)
