If a vampire gets hurt... do the bleed? oder do they heal straight away.. oder do they even feel pain?

Well if Du have ever read Eclipse,it says that nothing can make a mark on them,and they also cant feel pain. Only the Volturi can make them feel pain.

Well it depends on the type of vampire. there are many vampires. The older version of the vampire they could get hurt, but heal right away. The current Vampire dont get hurt at all.

it depends what Vampire Du are talking about

the cullens, for example-
in the books, it made them seem indestructable, the only things that hurt them was venom, feuer oder being pulled apart
in the movie, they do that thing where edward has cracks. i think that is rubbish.
