gecgooden / chunkgen Goto Github PK

I'm trying to generate a new world with a 42k x 42k area, I'm using the command "/chunkgen 0 0 2630 2630". It successfully adds data for the chunks that were already generated, but when It gets to new chunks, the server crashes. I was wondering if there's a way I can use chunkgen to generate chunks with RTG custom terrain for my server, or if there's something I can do to fix this. I need to generate it before I use pixelmon and sponge so that it generates correctly.

Versions:
chunkgen-1.8.9-1.3.0.jar
RTG-1.8.9-1.0.0-snapshot-2.jar

PS. Worldtype is BIOMESOP

From minecraft forums post:

Do you think you can make milestones (every 10x10 chunks?) post a message to the chat? I'm not getting any feedback that the chunkgen command even works.

I've got a number of dimensions created by JustEnoughDimensions and I want to generate chunks for them when the game first loads. Specifically I want to generate chunks at 0,0 where I can spawn a portal allowing players to enter the new region.

However when I opened the config file there was no slot showing for the optional dimension argument; the same thing with the config option in game. No dimension options.

Hello

Does this mod also generate terrain features like trees, plants ect?

There are many mods outside just generating the chunk without features, but what also consumes a lot o processing power is the features ie. from BoP, sometimes when I reach an area that is heavy to generate and travel around, I get kicked out due to timeouts till everything is generated.

So I also like to generate features, is it possible?

Cheers

Can i have some Install instructions please.

Pls update :)

Having an issue with the 1.7.10 edition: Somehow, biome 195, Thaumcraft Eldritchlands, tried to generate in the overworld and crashed the server.
I'm running a Cauldron 1.7.10 server. Any help to fix this, or at least to manually fix the "corrupted" chunks, would be fantastic!
Players will crash on log on, I teleported to the chunk to investigate and managed to crash the server.

Crash report:

I don't have the greatest machine to use as a standalone server, let alone, be able to handle just 2 players (just myself and my brother). The worldgen always crashed my server, so chunkgen is a God-send.

However, I realized that regardless where I start the generation, it always goes over already generated chunks. I can't put in 100 100 because it'll get about 50% and throw an out of memory error (6GB allocated with a C2Q Q8400). I was able to successfully generate a 75x75 area, which looks plenty, yet my endgame is 500x500.

I'm constantly hitting my cap, and it really doesn't matter which jvm arguments I use, it always caps out the RAM.

Would it be possible to add a logic to parse the region data really quick to see what has been generated, then go from there?

Thank you.

really nice mod. was wondering if a feature could be instead of disabling chunk loading when a player is online, you could set chunk loading to a different number. we have my server set to 5 chunks per tick when no players are online, but wed like to set it to 0.2 chunks per tick or something so it gens more slowly when someone is online.

Update it so that the dimensionID used is the one the player is currently in, not 0.

First of all thank you for developing this mod.
It might be small but its an essential mod for every server owner.

Then the actual request:

When generating a world on a server I try to generate them in pieces so I can generate them inbetween server restarts and when no users are online. This however leads to some complications.
Unless you manually subdivide the wanted area into regions that you should generate the mod does not take into account that some of the chunks already exist. And checks them one by one if they exist or not.

This works fine for small generations as the amount of chunks to check is small.
But this gets problematic when you are generating a 20.000 x 20.000 area consisting of rougly 1562500 chunks. Checking every single one of these chunks means loading rougly 1525 regionfiles (32x32 chunks each) from disc to check if the chunk exists. It might even load the same region file multiple times depending on the order in which it generates these chunks.

Keeping a list of which chunks have been generated in each dimension by chunkgen and previously skipped because a player generated them would be a nice thing to have.
Checking against that list at generation start could drastically reduce the number of read operations from disk speeding up the process alot.

It might not seem much of an improvement if you look at small area's but for large area's in multiple generation sessions it might actually differ alot.

When attempting to build i first got error with downloading mappings, changed what snapshot to fetch (from 1.9.4 to 1.10.2) but now i get errors

This is my first attempt at building an mod on my own, and im unsure what to do

Might be a good idea to code in an option for /save-all command every X chunks if server operators have /save-off on by default or for backup purposes.

savex=100 (issue a /save-all every 100 chunks)

Additionally an EmptyOnly option to run only when player count = 0 might be nice.

From past experiences with chunk generators it may be a good idea to have an option for less then 1 chunk per tick, perhaps an option for every N ticks. Say a TickSkip option.

/chunkgen radius 0 0 1000 ~ true saveex=100 tickSkip=1 (Effectively every other tick)
/chunkgen radius 0 0 1000 ~ true saveex=300 tickSkip=2 EmptyOnly=true (effectively every 300 chunks generated do a force /save-all, generating a chunk every 3rd tick and only when there are no players online)

Would it be possible to add a world border feature to this mod? So when you generate an area you could perhaps add a flag "addborder" to add a border to the area being generated. There then should probably be a padding (config option) beyond the border so you don't get untidy looking borders on Dynmap and the like when you bump into the border.

Perhaps the chunkgen could use Minecraft's build in border system for this?

Writing command, nothing happens, any logs i can provide?

On Forge 2641 and 2611 (tested both) I get the following crash after letting the game generate chunks for a while. The time varies depending on whether or not I have other mods loaded, but it's definitely chunkgen causing it as it stops whenever I remove the mod.

I know this isn't the Forge you built against, but currently the recommended Forge version for 1.12.2 is 2611 so I probably won't be the only one experiencing this!

java.lang.IllegalArgumentException: Cannot get property PropertyEnum{name=variant, clazz=class net.minecraft.block.BlockPlanks$EnumType, values=[oak, spruce, birch, jungle]} as it does not exist in BlockStateContainer{block=minecraft:air, properties=[]}

Crash log here (with no other mods but Optifine+shaders and Liteloader+Voxelmap), also: chunkgen.cfg I'm using

Version: chunkgen-1.12-1.5.0.jar - Mar 16, 2018

I couldn't fully understand correctly how the mod works, so just asking few questions.

Q1 The way the chunkgen command works when generating chunks, iam not sure how exactly it is done, so i drew(pretty shity) to clarify.

Q2 From my understanding the height and width is chunk and not blocks range, am i right?

Q3 Also i've noticed that my server has crashed around 15%, ticking exception, after it restarted the command doesn't continue(Like WorldBorder), and running it again it restarts the process from start again, but there is the config option to set the height and width in the config to do the gen after server start.
Does the config option work the same as the chunkgen(ie. "/chunkgen 0 0 625 625 0") command but it doesn't redo the chunks that have been already generated?

Also it seems the mod does check the chunks again to see if they are generated, wouldn't it be faster to store a file containing a list of chunks that would be marked true/false(true being generated/false un-generated) and just continue on the next non-loaded chunk?

I finally got around to running the new release, and it works, yay!

I ran chunkgen radius 0 0 400 from the console, which should generate a circle of radius 400 chunks from 0,0, which should work out to 6400 blocks, correct?

After it completed overnight, I ran a dynmap fullrender on the world to see the results, and got this:

Live map

It's a square map, going from almost exactly -4000,-4000 to 4000,4000. (The bits poking out North & South were from manual exploration before running chunkgen. I outlined the approx pre-existing area in red)

So it seems like the area algorithm for radius generation still needs some work?

Hi there!

I found your main github page linked to an older version of chunkgen (1.2.1). You may want to update the link to 1.2.3. Great mod, thank you for making it!

Clean MC Server: 1.10.2
Forge: forge-1.10.2-12.18.3.2297

I checked the source to see if there was any issues at com.gecgooden.chunkgen.ChunkGen.serverLoad the command class passed seams to be implemented just fine. To my surprise, the mod works perfectly in a development environment. I even loaded the released mod with a development build of minecraft and that worked perfectly too. However, If I do a clean download of forge and minecraft the mod gives me this error.

I even tried running minecraft with the same jre as my development environment but that didn't work either.

Anyways. I gave up, and I'm leaving this here for anyone interested.

fml-server-latest.txt

I get the above comment when trying to use the mod. Using 1.8.9, my Forge is 1808.

I type in:

/chunkgen zone 135 141 2500 2500 0

starting coords, amount of x and z chunks (40kx40k blocks), and dimension. I tried a bunch of other stuff but get the same comment. Any clarification is appreciated.

I know it sounds strange, but it seems the mod pretends to be doing something, but actually it isn't (see link). It has log output, and the percentage goes up (and it eventually finishes), but the actual files on disk aren't touched. I've tried running chunkgen radius 0 0 1000 0, left it overnight and it completed without problems. Only the world on disk was 17 MB, and that's kinda impossible. Am I doing something wrong?

https://asciinema.org/a/5p8ljlqlqeczr57rmghdwag5h

Can you add a confirmation dialog that pops up when the amount of chunks exceeds an amount? Basically just way for the game to tell "Hey you are about to generate 15,000 chunks. Are you sure you want to do this?"

Also along with this can you add a command that allows you to calculate how many chunks you are about to generate. Like the same thing as above but a command like "chunkgen calculate radius ~ ~ 50 0". Have the command tell you that will be ### chunks.

Will 1.7.10 version work with 1.7.2?

I am currently generating a big area on my server using the pr #33

But the number of entities and tileentities rises steady event with their respective chunks being unloaded. Is there a way to unload them too?

I feel like this version keeps running indefinitely until issuing /chunkgen stop. It looks like once it finished the area i set, it just starts over again and I'm assuming just loads and unloads chunks since they are already generated. Before I went to bed last night it had generated about 2.7 GB of data (over the course of about 8 hours) and was still running this morning, but only an additional 100MB of data was written to the disk all night bringing the total to 2.8 GB. Is this normal behavior?

Edit: just SSH'd into my sever while on lunch and the chunkgen process is still running, I never actually stopped it this morning and it still hasn't created anymore data. I'm guessing it's safe to say the process is finished

Using v14:

Random lines of chunks are not populated. The issue is here. As I explaied in my comment to issue #2, you need to generate chunks at (x, z), (x+1, z), (x, z+1), (x+1, z+1). In any order.
The order doesn't matter because if you, for example, generate chunk at (x+1, z) it will also try to populate chunks at (x+1-1, z), (x+1, z-1), (x+1-1, z-1).
Your way mostly works because you don't explictly unload chunks. And apparently forge unloads them automatically. And when forge unloads chunks - some newly generated chunks won't be populated.

https://paste.ee/r/z3Wdn

I wanted to pregen a new world so i download chunkgen-1.10.2-1.4.0.jar from https://github.com/gecgooden/chunkgen/releases dragged and dropped into server mods folder and started server

I am not trying on an existing world i made a new world let it generate it did as soon as spawn generated the server crashed

Admittedly i do have a ton of mods installed and rtg is also installed but it was not mentioned in the crash at all

"[14:54:21] [Server thread/INFO]: Preparing spawn area: 92%
[14:54:22] [Server thread/INFO]: Done (16.295s)! For help, type "help" or "?"
[14:54:26] [Server thread/INFO]: Stopping server"

Updated to AlltheMods 3.0.1 and now I crash just after server world load:

trimmed to just the error:
trimmed_error.txt

the entire forge log if needed:
fml-server-latest.txt

Likely some change in forge since they did update to 2422.

When I pre-generate maps with the mod and then run mapping software such as JourneyMap (client-side) or DynMap (server-side) the results are maps that map out the biomes, but trees/foliage only appear where players have traveled.

Sample from JourneyMap: http://imgur.com/9atu8eo

Not sure exactly what to classify this as.. I don't see it quite as a bug.. maybe a feature request?

When I try to create a world I get an endless "Building terrain" while this mod is installed.

(Can't label as a feature-request for some reason)

Please add "chunkgen echo [on/off]" and "chunkgen status" commands. So we don't have to deal with massive console spam, which makes typing in new commands difficult.

Also, if possible...

This command might be used when no players are logged in, you may want to keep the chunk at x/y loaded the whole time to reduce other console spam. Like:

[Server thread/INFO] [FML]: Loading dimension 1 (world) (net.minecraft.server.dedicated.DedicatedServer@5e68ce60)
[Server thread/INFO] [FML]: Unloading dimension 1

Progress updates are off by a factor of 100.

So, instead of showing 99.546%, it shows 0.99546%.

I currently have this installed on only the server.
I run the command and get no response saying it started or anything.
Running /chunkgen stop says it stopped but that's regardless of if a generator is running or not.
#3 says that progress updates were added but they never appear.

The 1.8.9 version of 1.3 crashes while loading with the following exception:

Tested with Forge 11.15.1.1808

In fact building it doesn't work at all. Fix the obvious code error, however, and you get a ConcurrentModificationException on startup.

Can you take a look?

I have a weird request. We're using ExtrabiomesXL on our current map and it has some issues with decoration (namely biomes with a lot of leaves). Anytime chunkgen gets to a chunk that ends up being a "leafy" biome, we end up with 9000ms-30000ms tick periods. (this is not an exaggeraton!)

It would be nice if somehow chunkgen could somehow allow fractional values so that instead of loading 1 defined by numChunksPerTick, I could specify something like .025, meaning it would load one chunk every 40 ticks. I'm open to other solutions if you can think of something more efficient or easier to code.

Hello

As I'm using this, I already have lots of chunks that are generated just partly, means, just landscape no features and or just the "chunk file" (so also the chunk) already exists, but is completely empty (8kb file on harddrive for example)

Therefore I'm looking for a way to "force-load" chunks, even if they already exist and generate whats missing.

So force the chunk generation, skipping the "chunk already exist" check and just try "generation".

Should be possible, right?

Thanks & Regards

Chunkgen seems to loads chunks as quickly as it can with no apparent limiter. If forge doesn't unload chunks faster than chunkgen is loading them the server eventually dies. The chunk generator says unloadChunksIfNotNearSpawn but that doesn't seem to be as fast as chunkgen is loading them. Ram for the minecraft server is 2.5GB and total ram in the server is 8gb. RAM normally isn't ever an issue unless I use chunkgen on a large area. Would it be possible to check for the number of loaded chunks when starting gen then pausing the gen for a bit if the loaded chunks get say 250 more than that initial value? Or perhaps add in a manual save-all every so many chunks to help convince forge to unload the chunks?

/chunkgen 0 0 100 100 0

This becomes even more apparent when /chunkgen 0 0 100 100 0 crashes then after starting back up you repeat the command only to have it crash even faster.

To ensure that chunks are populated, sponge chunkgen for example always generates 4 chunks at the same time.

Looking at the log output your mod is giving, chunks are generated in stripes of 1, so would it be possible to increase the striping to be 2 thick?

Upon generating and loading the world the server crashes. Here is the crash log and all the mods included.
