Hello. I am adding a function into one of my plugins that allows RPGs and grenades to destroy the ground, buildings and terrain. I have got that to work, but I can not seem to find a way to make it come back. What is the best way to reset a map. It is about 1000 by 1000 blocks and I only need to reset from 30 Y to 125 Y. How would I go about doing this with all the players on? EDIT: Better yet. How would I make it all come back in 60 seconds with out making torches, ladders, signs, and sand fall. I have a delay set up, but the problem is when it puts the blocks back there is a chance that a bed, door, trapdoor, sign, ladder, torches, ext will fall. How would I make the terrain destroyed respawn with out any changes?
