(Just got back into making em minecraft plugins so im not familiar if any new stuff arrived) So i need ways to store blocks/locations,basically a player places a specific itemstack,i save it and use it in other stuff Last time i basically listened to blockplaceevent,saved the block,then in another class iterated through it and used it(an AutoFarm plugin),basically checking every 10 second a list of blocks and do stuff with that... Question is,is there a better way to do this? Or should i just keep going with it Why do i need it? A item generator basically every <sec amount> i do certain stuff(either spawn or insert item in the world) So current method,save block on place,loop through the config,use it
