Downloader World 777
Orville Marquez
World Downloader, abbreviated WDL, is a mod that allows saving of a world on a remote server for singleplayer use. Mainly, this means that it can be used to backup your creations on a server. This is a continuation of the older version by cubic72 and nairol.
Currently 1.11 builds are experimental and may not work correctly. Entity tracking is disabled for now, meaning that the mod will not save entities in chunk that were unloaded. Additionally, the game will crash if you open a horse inventory while downloading. If you encounter any other issues, please file a bug report; I'll work on fixing these bugs by the next release.
Currently 1.10.2 builds are experimental and only available for liteloader; future updates should provide both forms. You may need to manually fiddle with liteloader and forge to get these versions to work.
These versions are for Minecraft 1.8.8, and can connect to servers running Minecraft 1.8 to Minecraft 1.8.9. It is installed on clients running Minecraft 1.8.8. There is only a base edit version avaiable; use 1.8.9 instead if you need compatability with other mods. This version is incompatible with optifine 1.8.8 (but you should use optifine 1.8.9 anyways)
Older, non-actively maintained versions of WorldDownloader for versions of minecraft before 1.7.10 can be found in the old thread or via the GitHub releases page (within the 'src' download of very old versions).
For most versions, there is no forge version of World Downloader. However, you can use the Liteloader version with Forge, which will generally work. Look on the liteloader thread for instructions on how to install with forge, and then insert the .litemod file as described above.
For 1.14.4 and 1.15.2, there is a new experimental version of World Downloader that uses Forge. First install Forge, and then put MixinBootstrap and the appropriate WDL jar file into the mods folder. These versions require MixinBootstrap to run properly, and will not work without it (you will be prompted in chat to install it).
World Downloader has an automatic update checker that fetches an update list from GitHub. No personal information is sent appart from the current version as part of the User Agent (which is standard for any HTTP request). This update check also performs some basic validation to ensure that the download is not corrupt. You can view more information on how the updater works, both internally and visually, on the project wiki.
This mod does communicate with the server for permission checks. These are intended to add permission requests to the mod to adress the concerns some server owners have about misuse. A few servers do automatically ban users when it detects the mod being installed; while I do not support this action in any way, it is important to be wary of the fact that some servers do this. The vast majority, however, either do not use this system or implement the in-mod permission request system. Please contact a moderator on your server for details (they generally like being notified before you install the mod as to what you wish to download).
TL;DR: To make use of the mod, simply join a server, pause the game, and click "Start download". If the server is multiworld (has more than the 3 vanilla minecraft dimensions), make sure to indicate as such. Travel around the world, making sure to load the parts you want to save, and opening any chests / other containers, and when you are done, pause, and click "Stop downloading".
Join a server, and then pause and select "Download this world". If this is your first time using the mod on that server, make sure to chose the appropriate multiworld mode -- if the server *only* has 3 worlds (the overworld, nether, and end), multiworld is not needed, but if it has any more worlds or has worlds beyond those official worlds, multiworld is required or you may end up overwriting data from one world with that of another. After that, you may wish to pause again and click the 3 dots next to the download button, allowing you to further configure the download options for that world.
Once you've started the download, you need to travel around the world. World Downloader will only save chunks that you can see -- if the game never loads it, it will not be saved. (However, once a chunk is loaded, the entire vertical section is saved.) For most servers, this is a range of 10 chunks (160 blocks), but it might be more or less depending on the server. You will need to open chests and some other blocks for them to be saved. See this section for more info.
If you want to use World Downloader with other mods, note that it might not save everything from other mods. For instance, it most likely will not save containers such as chests. However, it'll still probably save most of the downloaded world. World Downloader has not been tested with other mods.
World downloader is a mod that is mainly intended for use by players to make copies of their own creations. However, you may be afraid that someone will use the mod to create a copy of your own map, or another thing that they didn't build, and then put it on their own server. While I can't say that that isn't a risk, it doesn't mean you should entirely ban use of the mod (or players who use the mod).
Additionally, it only downloads the area that a player travels to -- it is impossible to download the entire map without traveling through it. World Downloader requests no more data than a vanilla client -- it simply writes the data that is normally sent. In essence, use of this mod will not have any affect on server performance.
It's preferred to report bugs on the GitHub issue tracker, but if you're not sure or don't want to register an account there, feel free to post in this thread and I'll create a ticket. The tracker is available here.
WDL is licensed under the MMPLv2. Among other things, this means that you must request permission before redistributing this mod (modified or unmodified). Also, custom versions must be open source. For more information, please read the license page.
Versions of the mod targeting old Minecraft versions may also include a copy of the FastUtil library (specifically the partial version Mojang used before 1.12), which is licensed under the Apache License 2.0.
It doesn't work for me! I tried everything: coremod, bin, magic launcher, multimc, liteloader but nothing worked: liteloader doesn't detect this mod, magic launcher doesn't launch, multimc crashes after launching, coremod with nothing else doesn't launch, same as bin.
Hi there! Will this mod get an update to 1.8.8? I've seen an AMAZING island house on a server yesterday and I really want to download it, change a few things and play with it, maybe expand it to a city (In singleplayer of course, not to steal it.) The problem is obviously that the server is on 1.8.8. I'm pretty sure it would be a LOT more popular if this was on the latest version. It would be awesome if you could update it to 1.8.8. But even now, this is really useful. Thanks!
You should still be able to connect to the server with this mod even if the server runs 1.8.8, as 1.8.0 and 1.8.8 are compatible networking wise.
The main thing that keeps me from updating to 1.8.8 is the absence of a MCP release for 1.8. Without one, it's very hard to create mods as one would have to use the obfuscated source.
I still might try to make a version with it, but it would be extremely difficult.
WorldDownloader needs to be put inside of the actual minecraft jar; forge can't load it directly. Theroretically, you should be able to put it in just 1.7.10's folder (forge uses that jar to start), but it seems like forge doesn't like the modified class.

The World Ocean Database (WOD) is world's largest collection of uniformly formatted, quality controlled, publicly available ocean profile data. It is a powerful tool for oceanographic, climatic, and environmental research, and the end result of more than 20 years of coordinated efforts to incorporate data from institutions, agencies, individual researchers, and data recovery initiatives into a single database. WOD data spans from Captain Cook's 1772 voyage to the contemporary Argo period, making it a valuable resource for long term and historical ocean climate analysis. Original versions of the 20,000+ datasets in the WOD are available through the NCEI archives.
Use the WODselect retrieval system to search the WOD by specific parameters (date, geographic area, probe type, etc.) and measured variables. View a dataset distribution map and cast count of your search criteria, and download a custom dataset in WOD native, csv, or netCDF.
The WOD consists of periodic major releases and quarterly updates to those releases. Each major release is associated with a concurrent release of the World Ocean Atlas (WOA), and contains final quality control flags used in the WOA, which includes manual as well as automated steps.
Each quarterly update release includes additional historical and recent data and preliminary quality control. The latest major release is World Ocean Database 2018 (WOD18), which includes more than 15.7 million oceanographic casts made up of 3.56 billion individual profile measurements.
The oceanographic data that comprise the WOD have been acquired through many sources and projects as well as from individual scientists. In addition, many international organizations such as the IODE/GODAR and WDS have facilitated data exchanges, which have provided much data to the WOD. The World Ocean Database (WOD) is an NCEI product and an IODE (International Oceanographic Data and Information Exchange) project. This work is funded in partnership with the NOAA OAR Global Ocean Monitoring (GOMO).
The WOD is made up of ocean profiles, which contain measurements for a single variable (temperature, salinity, etc.) taken from one location at different depths, or a horizontal string of readings taken from the surface. WOD profiles must contain more than a single depth/variable pair. Multiple profiles taken at the same location with the same set of instruments form an oceanographic cast.
