How is it done? Gradual building process

Hi,

I was recently watching a video and I saw the plugin on the server was gradually building buildings. It looks really cool imo and so I was wondering if anyone knew the best of going about recreating this? Including the armor stand functionality too, ideally

You can see it at:

@timtower I figured one could do it that way, but wouldn't that be mega tedious? To write out each BukkitRunnable and write out code to replace every single block manually? Or is there a better way to do it, with WorldEdit perhaps?

EDIT: Also look at the building exploding here:

How on earth did he do that?

 

@timtower Any idea how he did the building explosion where the blocks fall like TNT and become solid blocks where they land to mimic debris? At 19 minutes in the video there is an example, can't link to the exact moment for some reason. What sort of list would you store those blocks in then? A HashMap?
