    Thanks for doing this, I appreciate your efforts. I'm surprised there's not a donation link. Or did I just miss it?


    I don't have one, to avoid a conflict of interest. That said, if you want to send money to someone, please consider donating to the Internet Archive, since the work they do is fairly important. (Donations to them are tax-deductible in the United States, and they also have a matching program going on currently, so now's a great time to do it.)

    The 3.x series supports older Minecraft versions. However, it no longer is maintained or supported, and is only linked here for reference.


    Base edit versions are inserted directly into the Minecraft jar and are developed by me (pokechu22). Liteloader versions are for liteloader and are developed by julialy.


    Jump to: 1.11 • 1.10 • 1.9.4 • 1.9 • 1.8.9 • 1.8.8 • 1.8 • 1.7.10


    Minecraft 1.11

    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.


    Minecraft 1.10.2

    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.

    You can also also use 1.10 builds to connect to 1.10.2 servers if necessary.



    Minecraft 1.10

    These versions run on Minecraft 1.10, and can connect to servers running 1.10 and 1.10.2. 1.10.1 is possible but discouraged due to bad tileentity changes made in that version and reverted later.



    Minecraft 1.9.4

    These versions run on Minecraft 1.9.4, and can conect to servers running Minecraft 1.9.3 and 1.9.4.



    Minecraft 1.9

    These versions run on Minecraft 1.9. Note that it is not compatible with 1.9.1 or 1.9.2, so you must use a 1.9 client.



    Minecraft 1.8.9

    These versions are for Minecraft 1.8.9, and can connect to servers running Minecraft 1.8 to Minecraft 1.8.9. It is installed on clients running Minecraft 1.8.9


    Minecraft 1.8.8


    1.8.8 builds have been discontinued. Please, consider using 1.8.9 or 1.8 instead.


    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)



    Minecraft 1.8


    These versions are compatible with servers running Minecraft 1.8 to Minecraft 1.8.9. They are installed on clients running Minecraft 1.8.



    Minecraft 1.7.10


    These are versions compatible with servers running Minecraft 1.7.6 to Minecraft 1.7.10. They are installed on clients running Minecraft 1.7.10



    Older versions

    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).

    Installation instructions (↑ Return to contents)

    Follow the appropriate set of instructions for your intended method of installation.

    Base edit

    I recommend using MultiMC to automatically install the mod. MultiMC is a separate launcher that automates mod management. For older versions you may want to use magic launcher.



    1. Download MultiMC from its website.
    2. Run MultiMC.
    3. Select the new instance button

    4. This window will appear. Enter the name ("1.9_WDL"), optionally select a group ("WDL"), and make sure that the version is 1.9.

    5. Then, select OK once you've got what you want.

    6. If this is your first time using MultiMC, it will download the game assets (sounds and such). This might take a minute or so.

    7. Once you're back at the main MultiMC screen, select "edit instance" in the sidebar.

    8. Select "Add to Minecraft.jar" in the side bar. You may be prompted to confirm that this is the right way to install the mod; in the case of World Downloader, it is. (Note: the above screenshot is from an older version of multimc where the button was named differently).

    9. Select the zip file for the mod that you downloaded earlier.

    10. Close the edit instance window, and then launch your newly installed version by double-clicking it or by selecting play.


    You can also install the mod directly as a launcher profile. This is more complicated, but if you don't want to download a separate launcher, this is the only way.

    Full instructions with screenshots: https://imgur.com/a/YLqClkW


    Text instructions:

    1. In the first post of the World Downloader thread, find the section titled "Downloads". Click on the link for the Minecraft version you're trying to use.

    2. On the GitHub page this takes you to, click on and download the base edit file for your Minecraft version. (It should contain the word "baseedit" and "mc#.#.#.zip", where #.#.# is your Minecraft version number.)

    3. Go to your ".minecraft" folder, then go into "versions". Create a copy of the folder for the correct Minecraft version and rename it to "#.#.#.wdl".

    4. Open this folder. Rename the two .jar and .json files here to "#.#.#.wdl . jar" and "#.#.#.wdl . json".

    5. In your text editor of choice, open #.#.#.wdl . json. You need to edit 2 things:

    • "downloads" section: This section contains 4 subsections, "client", "client_mappings", "server", and "server_mappings". It will be near the top of the .json file, will start with
      •     "downloads": {"client": {"sha1":





      and will end with
          server.text"}},





      Delete all of this section. (See https://i.imgur.com/HHckF19.png for details)


    • "id" section: This section will be right after what you just deleted and will look like
      •     "id": "#.#.#",





      with #.#.# being the original version number. Add ".wdl" to the end of that number. (See https://i.imgur.com/zpYeTta.png)

    6. Save these changes. (Should look like https://i.imgur.com/Pigx1E5.png)

    7. Open #.#.#.wdl . jar with 7-Zip or another archive manager and delete the folder "META-INF".

    8. Copy all the files from the World Downloader zip file that you downloaded in Step 2 into the .jar. Overwrite and merge folders if it prompts you to.

    9. Start the Minecraft Launcher. Click "Installations" at the top, create a new profile, and select "#.#.#.wdl" in the "version" dropdown.


    (For reference only; may not work nowadays)


    Based off of cubic72's instructions here.

    Using new launcher:

    (Replace 1.x.x with 1.8.9, etc in these instructions)

    Note: If you have a recommendation for simplifying these, let me know. Do no just say MAKE IT FORGE COMPATIBLE. Forge does not have the hooks for directly capturing network and screen events.

    1. Close the launcher
    2. Copy the .minecraft/versions/1.x.x folder to .minecraft/versions/1.x.x.wdl
    3. Go into folder 1.x.x.wdl.
    4. Rename 1.x.x.jar to 1.x.x.wdl.jar
    5. Rename 1.x.x.json to 1.x.x.wdl.json
    6. Open 1.x.x.wdl.json with a text editor of your choice.
    7. Change the "id" value to "1.x.x.wdl" (the name used elsewhere).
    8. Scroll to the bottom of the JSON file and delete the entire "downloads" block near the bottom.

      9. To clarify, since there are multiple "downloads" blocks, you want to scroll to the bottom (or sometimes, the top) of the JSON file and replace the following

        "mainClass": "net.minecraft.client.main.Main",
  "minimumLauncherVersion": 18,
  "assets": "1.9",
  "downloads": {
    "client": {
      "url": "https://launcher.mojang.com/mc/game/1.9/client/2f67dfe8953299440d1902f9124f0f2c3a2c940f/client.jar",
      "sha1": "2f67dfe8953299440d1902f9124f0f2c3a2c940f",
      "size": 8697592
    },
    "server": {
      "url": "https://launcher.mojang.com/mc/game/1.9/server/b4d449cf2918e0f3bd8aa18954b916a4d1880f0d/server.jar",
      "sha1": "b4d449cf2918e0f3bd8aa18954b916a4d1880f0d",
      "size": 8848015
    }
  },
  "assetIndex": {
    "totalSize": 120490344,
    "id": "1.9",
    "known": true,
    "url": "https://launchermeta.mojang.com/mc-staging/assets/1.9/092c59b361816c7fa7f000587caa977c515b179c/1.9.json",
    "sha1": "092c59b361816c7fa7f000587caa977c515b179c",
    "size": 137075
  }
}














      with this:

       "mainClass": "net.minecraft.client.main.Main",
 "minimumLauncherVersion": 18,
 "assets": "1.9",
 "assetIndex": {
 "totalSize": 120490344,
 "id": "1.9",
 "known": true,
 "url": "https://launchermeta.mojang.com/mc-staging/assets/1.9/092c59b361816c7fa7f000587caa977c515b179c/1.9.json",
 "sha1": "092c59b361816c7fa7f000587caa977c515b179c",
 "size": 137075
 }
}

      (You don't want to replace it with exactly that text; this only shows the layout). This is needed because otherwise the launcher thinks you ahve an out-of-date version.


    9. Open 1.x.x.wdl.jar with 7-zip or another archive manager.
    10. Delete the META-INF from within 1.x.x.wdl.jar (this folder is used to check if the jar has been modified).
    11. Copy all of the files from within the World Downloader zip file into the jar, overwriting files and merging folders if prompted.
    12. Restart the launcher, "edit profile" (or make a new profile) and "use version" 1.x.x.wdl.

    * You can the .minecraft folder on ...
    Windows by entering %APPDATA%\.minecraft in an Explorer window or in the start->run dialog.
    Linux by opening ~/.minecraft/ in a file manager of your choice.
    Mac OS X by opening ~/Library/Application Support/minecraft in Finder.


    Liteloader

    Note: DO NOT EXTRACT THE .LITEMOD FILE! The .litemod file is what is manually loaded. Some browsers may automatically attempt to open it; if you use safari either you can find the original zip in the trash, or the automatic opening in Safari's Preferences (Safari —> Preferences... Untick "Open 'safe' files after downloading").


    In most cases, you should be able to just install Liteloader and then put the .litemod into the mods folder. Sometimes, that doesn't work, in which case you need to follow the instructions below.

    9. Run Minecraft using your LiteLoader 1.8 profile, join a server, hit Esc, click "Download World", run around to load the chunks you want to download.



    Forge

    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).


    Disclaimer (↑ Return to contents)


    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).


    I cannot be held responsible for any issues caused by the use or misuse of the mod. As per the license:

    How to use World Downloader (↑ Return to contents)


    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".


    Detailed usage

    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.

    When you are done, pause the game and then hit "Stop downloading".

    What World Downloader saves (↑ Return to contents)


    World Downloader automatically saves some things, but other things must be manually saved, and still other things can't be saved at all.


    Automatically saved

    • World terrain
    • Entities (may need range configuration on some servers)
    • Most tile entities, such as signs and banners
    • Your inventory, position, and gamemode
    • The server spawnpoint

    Manually saved

    • Chests and other containers -- they must be opened to save
    • Villager trades (must be viewed to save)
    • The server seed -- must be manually entered (will be filled in if /seed is performed, but you must be op)
    • Command blocks (must be opened, but note that you need to be an OP on the server to open them)

    Not saved at all

    • Your bed respawn
    • Other players
    • Jukebox contents

    Compatibility with other mods (↑ Return to contents)


    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.

    No guarantees can be made about functionality with other mods. If you experience crashes, feel free to report them, though.


    Information for server owners (↑ Return to contents)


    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.

    Finally, note that the mod does not know the server seed unless players have access to /seed; it only saves what can be seen.


    If you want to configure the mod to only operate on permission requests or similar, there is a plugin channel configuration system (and a Bukkit plugin for it).


    Please send me a private message if you want to chat about use of this mod on your server.


    See the wiki for more information on how World Downloader works

    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.

    Please include the full log file in the crash report, along with any other information (such as the server IP) as necessary.

    There is wiki here, which is somewhat bare but covers most of the GUIs and some other information.

    Hello, I have a bug report.

    I used multimc with latest version of world downloader for mc 1.16.4

    But I can only use the world downloader once

    When I tried to download the same map a 2nd time it crashes

    So everytime whenever I wanted to start multiple downloads of many different areas of the map, I have to keep logging in to the server everytime after a download is completed.

    Is it possible to fix, or it's just a server issue?




    See https://github.com/Pokechu22/WorldDownloader/issues/227 - this happens when backups are disabled due to me closing the old saveHandler only when backups are enabled. It'll be fixed in the next release (whenever that is), but for now you can work around it by enabling backups and then pressing esc to cancel the backup.

    I have tryed it multiple times but my game always crashed

    (i am trying to download a modded server)


    Can you post the crash report? (Upload it to pastebin.com or a similar site and then post a link here.) I'd be able to determine if it's directly caused by the use of 1.16.4 on 1.16.5, or some other modded compatibility issue. (I can't guarantee that content from mods will be saved properly, but it's something I can still try to improve.)

    Hi,


    When i join a 1.16.5 server the mod instantly says i need to download the newer version of the mod but i cant find it.

    Is there a way to get the 1.16.4 mod to work on 1.16.5 or is the 1.16.5 version already out?



    There isn't currently a 1.16.5 version of the mod. However, 1.16.4 and 1.16.5 are protocol-compatible, so you should be able to use a 1.16.4 client with the 1.16.4 version of the mod to join 1.16.5 servers. There's also a chance that the 1.16.4 version will work on 1.16.5 (that message is just a warning, not a fatal error), but I can't guarantee it (if things don't crash, it'll probably be fine though).


    Apologies for not having a 1.16.5 (or 1.17) version out yet; I've continued to be busy which has given me little time to work on this.

    Hey,

    Do you know why my downloaded world doesnt generate new chunks beyond those downloaded?


    I'm using this to move my builds from a dead server onto a later update but once I travel to the edge of what I have downloaded, no more chunks generate and the biome is 'The_Void'.

    Even if I teleport to 1000s away the same issue persists and it is still 'The_Void' (spooky)



    Thanks in advance!

    Hi,


    WDL doesn't know the server's seed, so it defaults to using empty chunks for world generation (to avoid creating mismatched terrain).


    While downloading, you can configure the world generator from the "World Generator Overrides..." menu in the "..." menu. If you run /seed while downloading (and have permission to do so), the seed will automatically be filled in there as well. Note that downloading again when there already is a world updates the chunks that you save, but does not get rid of already saved (or generated) chunks.


    Note though that the void chunks that have already been generated will remain generated, so you will need to restore from the backed up copy of the world created immediately after downloading, located in .minecraft/backups. (This would need to be done before starting downloading again.) If you don't restore that backup, then the chunks you already generated will remain void, though new chunks will be generated further out.


    If you're no longer able to download from the server, you can also create a new singleplayer world with the appropriate generation settings, and simply copy its level.dat over the level.dat from the backed up downloaded world; it'll achieve the same thing (though if you do this replacement and then download again, the modified level.dat will be overwritten and will use WDL's world generator configuration instead.)


    Hopefully that explains why it's happening and how you can fix it.

    Hi Pokechu22!


    Thanks for this amazing mod! I've been using it for a few years since the 1.8.x days, and it always worked well.


    However, recently I've been using it on a 1.12.2 server, and I noticed that sometimes my ender chest items will not save.


    I've managed to find a way to reproduce the issue:


    1. Join the server, start downloading, open and close an ender chest, stop downloading and disconnect;

    2. Load the saved world in singleplayer, the ender items shows inside the ender chest;

    3. Join the server, start downloading, do not open any ender chest, stop downloading and disconnect;

    4. Load the saved world in singleplayer, the ender chest is now empty.


    My setup:

    - Minecraft Java Edition 1.12.2 (Both client and server)

    - WDL: mod-litemodwdl-4.1.1.0-mc1.12.2.litemod

    - Java 1.8.0_201

    - Windows 10


    Not sure if this is an issue with WDL or Minecraft itself?


    Thanks!


    Hi,


    Yeah, that'd be an issue with WDL. Most inventories are imported from the saved version if they haven't been opened again, but that happens when the chunk is being saved, and doesn't apply to enderchests since they're saved in the player data file instead. This should be possible to fix nowadays though since level.dat is already opened to read GameRules; the only think that requires careful logic is making sure to use the new enderchest if one was saved. I'll try to fix it in the next version.

    Hi there! Any news on when you will update to 1.16.4? Pls reply :D


    It's planned; I've just been extremely busy lately (and also have been delaying because I still am trying to get working Fabric support done, but haven't had time to do it properly). I should have more time this weekend, so I'll try to get at least something out then. Sorry that it's taken so long (and that updates in general have been slower than they could be).

    I've released version 4.1.0.2. This update fixes several bugs and adds support for Minecraft 1.16.3.


    • Fixed world generation settings not being saved properly in 1.16.
    • Fixed players always being saved in the overworld, regardless of their current dimension.
    • Fixed chat coloration in 1.16.
    • Villager XP is now saved; this fixes some cases where (novice-level) villager trades would get reset. However, if a villager has never been traded with and has 0 XP, it will still have its trades get reset for now.
    • Added support for 1.16.3 and Forge 1.16.3.

    Note that I plan to drop Forge 1.16.2 (but not base-edit 1.16.2) in the next version, to reduce clutter and because the forge team is not maintaining it.

    I've released v4.1.0.1. This release improves overall stability, and adds support for 1.16.2.


    • Added support for 1.16.2 as a baseedit and Forge 1.16.2
    • Fixed Forge 1.14.4 and Forge 1.15.2 crashing on startup
    • Fixed some dimension issues with 1.16
    • Fixed button positioning in 1.16
    • Fixed the random crash when saving in 1.16

    Known issues:

    • WDL's chat messages still are not colored properly in 1.16.
    • Entity tracking still may not be completely correct.
    • World generator settings (possibly all settings) still aren't properly handled in 1.16. In particular, void generation instead defaults normal chunks.
    • Villager trades are not saved in 1.16.

    EDIT: One other thing: the entity realigner is disabled in 1.14+ currently since it doesn't work with 1.16.2. I don't think it actually does anything useful nowadays, so I might look into completely removing it, but for now it still shows up in the list. Also, for some reason the 1.09.4 litemod failed to upload; I've reuploaded it.
