Copying 64 Chunks (FAST)

Hello Curlip Here,

I am having more trouble copying a large area (8x8 chunks (4,194,304 blocks if my math is right)). I have been using the CuboidUtil and Block.setType() method which currently isn't cutting it. (Lag, Slow, and Crashes the server)

Can you help me fix/speed this up, because its a command for the general user.

And my Code:

Code:

Location playerloc = player.getLocation();
                World currentWorld = playerloc.getWorld();
                World tempWorld = this.getServer().createWorld(new WorldCreator(player.getName() + "temp").environment(currentWorld.getEnvironment()).generator(new EmptyGenerator()));
                
                Cuboid cube = new Cuboid(new Location(currentWorld, playerloc.getBlockX() - (16 * 4), 0, playerloc.getBlockZ() - (16 * 4)), 
                        new Location(currentWorld, playerloc.getBlockX() + (16 * 4), currentWorld.getMaxHeight(), playerloc.getBlockZ() + (16 * 4)));
                
                for(Block block : cube){
                    
                    Location getloc = block.getLocation();
                    Location setloc = new Location(
                            tempWorld,
                            (double) getloc.getBlockX() - playerloc.getBlockX(),
                            (double) getloc.getBlockY(),
                            (double) getloc.getBlockZ() - playerloc.getBlockZ());
                    
                    setloc.getBlock().setType(getloc.getBlock().getType());
                }
                
                player.teleport(new Location(tempWorld, 0, playerloc.getY() + 3, 0));
                player.setGameMode(GameMode.CREATIVE);

Thanks Curlip.

 

@curlip Please wait At least 24 hours before bumping.
If i understand correctly, you want to get a 8x8 area based on a center point? if so it wont be perfectly aligned since mid point of 8 is 3.5 so... it will be 4 to one side and 3 to the other.... (Note: i am thinking based on X,Y,Z axis) the thing changes if you want to select a region starting from point N ending to point Ω so it would be in the concepts of WorldEdit, a nested loop that will loop through the dismentions

 

@mine-care I need to copy an area of 8x8 chunks in which case it is a very large area and simply looping through the area is insufficient.

 

@curlip

Why do you need to copy so many blocks? There's likely a much faster way to do this.

 

@mythbusterma I need to copy this many blocks so the user can edit an area undisturbed.
This are would be copied to an empty world.

What are you recommendations, I could probably go back to 5 or six chunks in each direction.

 

I know WorldEdit uses a form of "fast edit" where lighting isn't done until all blocks are copied, I suggest you take a look at that.

 

@Lolmewn I'm trying to use WorldEdit but is seaming very complicated and difficult to understand. I also don't know where to find the Source code, I do have it loaded into eclipse.

 

@curlip You can find it here: <Edit by Moderator: Redacted bit url>

 

@Lolmewn Thank you (I think... )

I couldn't find anything on the subject blocks with WorldEdit so I began searching through the code, I also cannot find the code WorldEdit uses to copy blocks.

Any ideas anyone?

 

@curlip possibly you could just log all the changes made by a user and undo them individually at the end, so your not undoing the whole 8x8 chunks and just the number of blocks the player editted

 

@JUSTCAMH I am not undoing the changes, this will be the area the original player builds in.

 

@curlip

Well then spread the changes over multiple ticks, so as not to bog down the server.

 

dont copy "chunks" copy internal blockdata arrays

 

@RawCode

Because that won't have disastrous side effects....

 

Why no copy the world? Simply copy and paste and you have the copy of this world

 

@bohafr Then the user would be able to edit the entire world.
