I am looking for an event that catches cobblestone/stone generation. I am currently using onBlockPhysics, but it glitches when someone places cobblestone and causes a physics update. Thanks Tster Afforess - Would spout server-side be able to accomplish this? EDIT by Moderator: merged posts, please use the edit button instead of double posting.
Have you tried; http://jd.bukkit.org/doxygen/d4/ded/classorg_1_1bukkit_1_1event_1_1block_1_1BlockFromToEvent.html ?
i just tested this one out, this event is thrown... waaaaaaaaaaay too often, and will often return a block it tries, and fails, to expand into. if you check event.getToBlock() it will return weird blocks. you can check if the to block is cobblestone, because if its trying to push into cobblestone, it will give a false positive.
Try it like this not the best but works src.zip Pleas dont wonder because some strange declartion if you update yours it would be nice only make this for a request http://forums.bukkit.org/threads/req-cobblestone-to-ores-plugin.71879/#post-1085812
