Does the API support information when any block takes damage and from whom? I haven't had much time lately to look through it properly but it's not looking likely at this point, so I figured I'd ask and hopefully save some time. My aim will be to create a mod that will log any player that attacks your (or your clan) structures with the amount of damage done. This way when offline players log back in they'll be able to see who attacked them and thus remove the anonymity from offline raiding. I believe a mod such as this would be a huge boon for PvP servers.
That's a shame, but at least it's something with the core. Hopefully the Devs expand on the API at some point in the near future! Thank you for the answer, Xango2000.
