Bobby

Bobby is a Minecraft mod which allows for render distances greater than the server's view-distance setting.

It accomplishes this goal by recording and storing (in .minecraft/.bobby) all chunks sent by the server which it then can load and display at a later point when the chunk is outside the server's view-distance.

Optionally, it can also use an existing single player world to load in chunks which the server has never sent before. To make use of this feature, simply rename the world folder (not the name of the world! the name of its folder!) to "bobby-fallback".

Bobby automatically reloads its config file when it is changed. For an in-game config screen, install ModMenu and ClothConfig.

Setup

For setup instructions please see the fabric wiki page that relates to the IDE that you are using.

bobby's Issues

view-distance overwrite limit should be 32, not 16

Not sure why I thought it was 16 when even Sodium's render distance slider goes to 32 by default.

Can't load chunks saved using bobby as a single player world.

After moving the region files created using bobby into a single player world, when you load the world all chunks get regenerated, if spectatorsGenerateChunks is set to false the chunks just don't load.
The log just says
[23:32:53] [Server thread/ERROR]: Chunk file at [X, Y] is missing level data, skipping
for every chunk loaded.
Opening the world in minutor or amulet does work properly.
Using bobby 2.0.4 and Ubuntu 20.04.

Chunks do not have time to load on drawing above 32 chunks

When playing on a drawing above 32 chunks in a single world, chunks often do not have time to load
Here is a visual video dimostration

Also, as a possible correction in the view-distance-overwrite = 32 parameter, add the ability to set more than 32 chunks, namely as many as specified in the max render
since this is a single player game this can be completely fixed
I really hope that this can be fixed

Add ingame option to disable the mod

IndexOutOfBoundsException on FakeChunkStorage

Whenever I try and join a server, I see a lot of these errors on my client (1.17):
https://gist.github.com/breadbyte/cd5a467ceeb21c136b971350530be0a1

The line referenced is https://github.com/Johni0702/bobby/blob/master/src/main/java/de/johni0702/minecraft/bobby/FakeChunkStorage.java#L204

As a workaround I tried deleting .bobby, but to no avail.

Doesn't work in the nether

The mod doesn't seem to save the chunks in the nether. Havent tested the end but i assume it's the same issue there

In case this is intentional, could we get an option to turn on/off specific worlds?

Got this crash a few times when I loaded possibly a few too many chunks? I am not sure why, but removing the mod resulted in no more crashes. There came a point where every time I joined the server, I would get a crash. I even attempted to compile the source for my minecraft version (1.16.3), but that too resulted in the same crash.

Does this affect server performance?

Crash after a few minutes of being connected to a server

Maybe related to #10. My game crashes with bobby with this error message:

The game crashed whilst unexpected error
Error: java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 257
Exit Code: -1

and here is the latest log:
latest.log

it also happens without any mods.

Incompatibility with Immersive Portals?

Let me know if you need more details, but here's the gist.
When I use Bobby with my current few mods, it works just as advertised, but when I add Immersive Portals to the mix, Bobby appears to simply stop working. No crashes or anything, but my "artificially expanded" render distance reverts to the normal server render distance.
I don't use many mods at all, typically just Iris, Lithium, and a Leaf Culling mod. So I feel like my setup is sterile enough to deduce that it's just Bobby and Immersive Portals not playing nice. Not sure how though, and I'm not getting any errors or crashes to see why.

Sodium compatibility issue

When using Bobby 1.1.4 with a self build version of Sodium I get this error from Sodium (Newest version from the default branch)

https://ghostbin.co/paste/66vm7mj

I also have a older version of Sodium and with this version I dont get this error.
When join a server while this error occurs Bobby doesn't load any more chunks than the normal server distance.
When I remove Bobby and start my own build Sodium version I don't get the error anymore.

Water not rendering

water on bobby chunks doesnt seem to render (i use optifine so that might be the problem)
it looks normal when i come closer, and it still has a blue look to it so it might just be the way water is rendered (no idea)

[Question] How come saved chunks take up so much space?

The multiplayer world I'm in takes up 3GB in total, but as soon as I join the world and start saving chunks my SSD goes from 10GB free to 200MB. The weird thing is that Windows says .bobby only weighs 44MB.

Crashing on 1.17.1

I updated to 1.17.1 but whenever I join a server I crash with this: https://pastebin.com/RUycYW14

Async ViewDistance - Sentence

Hi, I have a cool idea!
Your plugin generates chunks, but if you can implement visibility like this plugin, it will be a breakthrough!

https://www.spigotmc.org/resources/fartherviewdistance.84950/

I would really like to see a similar implementation for 1.17 for my future Fabric server.

Player falls into the void after teleporting big distance

I'm playing on Wynncraft with this mod, in combination with Sodium. It works great, the only thing is that when I get teleported a big distance I often fall into the void because the chunks near the player don't load. Sometimes I don't fall down, but just hover in place.
Reloading all chunks doesn't work, I have to relog in order to fix this.

This is what it looks like:

Any ideas as to how to fix this? It looks like the server isn't fast enough in sending the chunks, but in vanilla this works just fine!

Did you hear about FarPlaneTwo mod?

https://github.com/PorkStudios/FarPlaneTwo
It's kinda similar to Bobby - it also allows rendering greater distances but the way it accomplishes this is more complex. Do you think your mod could borrow some functionality from FP2?

Loading visible chunks outside of max server loading distance

It would be nice if bobby optionally could forcefully generate/load chunks outside of the server's load distance, and then immediately unload them, leaving them only visible. Is it possible to make such an option?

Allow render distances higher than 32 chunks for other renderes.

Currently the max view distance overwrite is locked to clients with Sodium, while Canvas is also perfectly capable of delivering excellent performance under high render distances. I'm currently playing in a default minecraft world with Canvas Renderer and have a large view up to the limit rendered while still pushing nearly 200 FPS on what I would call a mid-high end machine running on AMD Ryzen 5 3600 and an overclocked GTX 970.

I'd love to see the higher max render dist support other renderers than just sodium, especially Canvas for now. I believe just using the same config option to replace the maximum value for the vanilla render dist slider as well would be perfect with a warning on the tooltip to not change it if using the vanilla renderer to make it simple 😄

Render distance limited to 32 chunks, even with Sodium?

I tried using both saved server chunks and a bobby-fallback world. I set the max render distance to 72 in the settings file, but chunks just stop loading where they would stop loading if the render distance was set to 32.

Bobby conflicts with new version of C2ME (0.2.0+alpha 4)

Yesterday C2ME released a new version that is now crashing when clicking on video settings if paired with Bobby. My best guess for why this is happening is because in this version C2ME added a new no-tick view distance.
See RelativityMC/C2ME-fabric#56 for more information as there is an issue already open on the C2ME github.

Disable for single player

Cause there's no point in having it there.

Forge 1.12.2 support?

Is it possible to work on Forge 1.12.2 support for this mod? If it is too much to ask for, that is alright.

bobby-fallback not working

Issue: Bobby does not load chunks from bobby-fallback folder

Folder is located in minecraft/saves, called bobby-fallback. Windows won't let me delete the folder when I am in the server, saying it is in use, which suggests it is in the right place. However, the game only shows chunks that I have been sent and does not show chunks from the bobby-fallback folder.

bobby cause VERY BIG lag spikes when i move between chunks.

if i disable bobby, the lag spikes go away. but if i enable bobby, there are big lag spikes (fps drops) whenever i move through a chunk border.
i tried to upload a screenshot, but it doesnt upload :(

Crash when teleporting (incompatibility with KubeJS??)

Whenever I teleport with a waystone or using the /home command, minecraft crashes. For some reason, /tpa usually does not crash the game.
Attached is a crash report. All of the crash reports i've examined look the same as this one.

Btw, this was on Bobby 1.0.0; I'm not sure if 1.1.0 has fixed anything. If it has i'll close this issue.

[Feature Request] Config option to differentiate between vanilla chunks and bobby chunks

I'd find it useful for PVP servers so you don't get tricked into thinking there aren't any players in the distance, but then they suddenly pop in once they reach the vanilla chunks. Not necessary to implement right now since the bug with starlight #18 is inadvertently what I'm looking for, but would appreciate it if you implement something like it if/when the bug with starlight is fixed after it leaves beta.

Allow client to generate its own chunks that the server has never sent.

This may already be a feature that I am too smoothbrain to get working. But I would LOVE to let my client render 32 chunks locally, and then when the server sends chunks have them replace the client generated chunks. So you could truly have a render distance further than the server's even if you are exploring new chunks.

I have tried setting up a single player world with identical world gen settings to my server, renaming the folder to bobby-fallback, and setting my client render distance to 32, and bobby's max render distance to 32, and single player server view distance to 32. But I still only see chunks that the server has sent to me. but they do stick around outside of the server's render distance!

1.1.0 not compatible with starlight

When using starlight none of the chunks loaded by bobby are lit at all

ConcurrentModificationException

Not sure if this is related to the other 2 issues.
I think it might be an indium incompatibility.

Fake chunks in tall worlds aren't fully unloaded

Chunks near the player are being unloaded in a weird pattern only to load again.

Related project

Not an issue, I just want to point to this related project I wrote ages ago.
It had a server component to sync chunks between players, so you can see ahead into areas you haven't explored yet.
It also only stored the exposed chunk sections to not illegally download hidden underground structures (it was being used on a server where secrecy matters and rules disallowed that) and also maybe save on performance.

Glad to see an updated mod with basically the same features, love your work.

Option to Force Generate Bobby-Render-Distance Chunks

It would be cool if there was an option to generate a worlds chunks in the render distance set by bobby, thus allowing the player to explore chunks and fully utilize bobbies increase render distance while exploring new chunks.

The only major downside of this i can see is laggy world generation, but personally, im happy to give up a bit of fps while exploring, to be able to see chunks at an extreme render distance like bobby allows.

Real chunks are not being loaded

Seems we're not done just yet, 1.1.2 broke loading the real chunks
Probably related to the fix of #19 but I feel like it's a separate issue

Map of saved chunks.

It would be easier to see which chunks have been saved and which still need to be loaded if there were an in-game map of all the saved chunks, similar to mircokroon/minecraft-world-downloader's map.

Help with port

Hello, I've been working on a forge port of Bobby for the last few days. It seems to be working for the most part, but when I use it in a large modpack I get issues and can't figure out why. If anyone is interested in helping me please lmk, I've made a separate issue with logs on my repo: natrow/sighted#1.

Full repo:

Issues with Starlight

When using Bobby with starlight on servers, the chunks that are stored are blacked out.

Here is my mods list. It works just fine with every mod but Starlight.

Strong lag in ReplayMod's viewer whenever the recorded player crosses a chunk boundry

bobby-2.0.2

Actions to reproduce

Crashes when joining a multi-server after startup.

Singleplayer Double Render Distance Slider

This mod is cool! however i did notice it does nothing on singleplayer.
I was thinking if you could create a second render distance slider (perhaps through modmenu's config settings), that controlled how far out these "illusion chunks" would render, that could be usefull for high-render distance performance in singleplayer. Since the game would not actually have these chunks active and being saved/loaded/etc constantly, and rather just rendered and nothing else.
Regular render distance setting: same as normal
Mod render distance setting: if larger than regular one, the saved chunks are rendered into the excess area. (essentially the same functionality the mod has right now, but with minor* changes to make it possible to use in singleplayer)

On some servers chunks flash when replaced with real chunks

I.e. when walking forward, chunks in front of you will shortly disappear before being replaced with real chunks.
Might be server-specific, happens on Wynncraft but couldn't reproduce in SP in my dev env.
Works as expected with Sodium 0.1 / Bobby 1.1.4.
Tried again with 1.1.4, and it's happening there as well now, so might just have been a change in how Wynncraft sends its chunks, not the Sodium 0.2 changes. Only tested with Sodium but not sure if it's actually required for the issue.

Crash problem

Are there any known incompatibilities between these mods? https://ibb.co/sbCwhFC

Disable saving loaded chunks to disk

Is it possible to add some sort of option that allows me to load chunks beyond the view distance set by the server but not save them to the disk either? Optifine is able to achieve the same thing this mod does without saving the region file to the disk so I was hoping it would be possible to implement something similar in this mod. The problem I'm experiencing at the moment is that when playing on creative servers with large buildings the folder in .bobby becomes very large because it's storing region files for every area that I visit

Light not being updated when breaking and placing blocks

It only seems to happen when there's a lot of chunks loaded (like 32 chunk render distance)
Even when placing a torch nearby it doesn't update the light
This is without any light modifying mods, but in case it would help these are the mods i'm using:

Architectury
Autorun
Betterbeds
Blockmeter
Blur
Bobby
Cloth-config
Cmdkeybind
Connected-block-textures
Dynamic-fps
Fabric-api-0.31.0
Fallingleaves
Hydrogen
Indium
Krypton
LazyDFU
Lithium
Logical zoom
Mod menu
Soaring Clouds
Sodium extra
Sodium 0.1.1 (latest build)
Tic-tacs

Very high memory usage

Minecraft frequently crashes due to out of memory errors. I've allocated 4 GB of ram to mc, and without bobby this does not happen nearly as frequently.

Unfortunately it is not in logs, but in MultiMC console it said unable to allocate 1 GB of memory for chunk::new or something like that.

Here are some logs anyway:
