How does the Hide action interact with attacking?

Quote from sabin76 >>

There is a difference between Rule Zero (DM can change, add, or remove any rules) and specific rules text calling out a DM's discretion to the dictate difficulty or circumstances of a thing happening. I agree that the former, while still RAW, is useless in these forums. The latter is very much not.

 I mean, RAW is itself mostly useless if you try to rule out GM interpretation.

 Alright, you've convinced me: this forum is useless, because everything is up to the DM, so we can't know anything, and there's no point in discussing what any text says.

Sometimes, what the text says is either inconclusive, or specifically says "ask the DM".
