Restore map without restart

Hello.

I'm in trouble.

Lets see a situation:
We have a world map. Player connect to server and do something on map for example cut trees, grass...
After X time I want to restore all changes to main map (without server restart)


Have You any idea ?

 

What I use to reset maps for stuff like minigames, is teleport everyone to a different world, and then unload the main world with Bukkit.unloadWorld(<world>, false) so it doesn't save the changes, and then load the world again with your preferences and then tp them back there.

 

You have three options:
1. The above
2. Teleport all players to a different world, unload and delete the previous, then copy over and create the new one
3. Schematics

 

Hmm the best option is @megamichiel I think.

But @RainoBoy97 could you tell me about Schematics? What is this?

 

@dram
Another option: You can get the blocks clicked, store them in an arraylist, and restore them whenever you want.
Third option: You can get the blocks clicked, create a runnable, and restore the blocks in the time defined

Also note: No players need to be moved to a different world for these methods

 

@ark9026

You know, a Set or LinkedList is a lot better for this than ArrayList.

 

@mythbusterma
Good point, but for this a runnable would probably be the easiest option.

@dram
If anything above solved your problem, be sure to put the [Solved] tag at the top

 

But you would still need a list of some sort. Because creating a runnable for each block broken is just... no.

 

I didn't say it would be the most efficient, but it certainly would work.
