Is there a plugin that makes it so wheneever a block is placed in gamemode and destroyed it will not drop any material?
You don't want it to drop the material in creative or survival mode? I thought that blocks don't drop already for creative mode?
I think he wants it so a creative player can place something like diamond blocks, and then survival players don't get anything for destroying them. Actually not a bad idea.
If the new Metadata system persisted then this would be simple and not laggy at ALL... Sadly though the Metadata system (added a month or two ago) is only a half metadata system...
