World Downloader (Continued from Nairol's mod)

Note: This is a continuation of the World Downloader mod by nairol. He is no longer able to work on the project and I have agreed to continue updating the mod, fixing bugs and adding new features. The old forum thread can be found here.

With this mod you can download parts of a multiplayer world while you are connected to the server.

Download World Downloader [1.5.2].zip (2013-05-06) (Supports Realms)

The links will always get the newest mod available for the indicated Minecraft version. The upload date is indicated after the filename. The above link is for World Downloader v2 (formerly WDL v2 BETA).

A most excellent mod spotlight video from iPodmail, thank you!


And, thank you SCMowns for this great review:


An in-depth preview video of the beta version's multi-world feature by Seto:

Installation (NOT Forge/ModLoader compatible):

Spoiler:

Open your minecraft.jar* with an archive tool like 7zip or WinRAR.
Put the class files you just downloaded in there. Overwrite if necessary.
Delete the META-INF folder if it exists in the jar file.
Close the archive and save if asked.
Done.

* You can find this file on ...

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

Screenshots:

Spoiler:

Important usage notes:

• You need to open chests while downloading or their contents cannot be saved.
  
• The mod can only save chunks which are sent by the server as you move around. If you see the chunk while downloading, then it's saved! If you don't move, it will likely only save 10 chunks (160 blocks) in each direction.
  
• The seed is not saved automatically. You must be op to request the seed with the /seed command. World Downloader will pull the seed automatically from the server response.
  
• When you click "stop download", wait until the world is saved to disconnect. You will be notified in chat.

Full Usage Details:

Spoiler:

What does it save automatically?

• All blocks that are within your range of vision (typically 160 blocks in each direction) as you move around.
  
• From height 0 (bedrock) to 255 (clouds)
  
• Your position, health, inventory, experience, gamemode (creative/survival), the time and the weather
  
• Mobs and animals
  
• Items that lie on the ground.

What doesn't it save automatically? How can these things be saved?

• Content of chests, ender chests, and dispensers -> Will be saved whenever you open them (right-click)
  
• Ingredients and products in furnaces and brew stands -> Will be saved whenever you use them (right-click)
  
• The note of note blocks -> Will be saved whenever the note is played (click/right-click/redstone)
  
• The seed value of the world -> It is no longer sent by the server. If you are op, you can use the /seed command and World Downloader will detect and save the seed automatically!

What can't be saved?

• Records that are in record players.
  
• The spawn position if it has been moved (by the admin or by sleeping in a bed).
  
• Offers from villagers are not saved at this time.
  
• Other human players of course!

FAQ:

Spoiler:

Does it start to download when I join a server?
No, you have to start and stop the download by pressing the escape key and clicking on "Download this world"

I want to download an area bigger than my range of vision. What should I do?
Walk around and visit everything you want to have in your copy while the downloader is active. (Or fly, ride, teleport, swim, ...) World Downloader works much like the maps in Minecraft. (The paper ones you can craft)

How long does it take to download a world?
As soon as something is in your range of vision (the 160 blocks mentioned above) it is also in your copy.
Again, think of Minecraft's maps.

Does this mod interfere with the server?
No, the mod doesn't cause any additional load on the server. It doesn't send or request anything.
It just looks at the incoming data, converts some data structures and saves everything as a singleplayer world.

Can this mod be used to synchronize my copy with the server world?
Of course! Just reconnect to the server and start the download. The mod will update your copy of the world to the current state. Any changes you made in your copy, in the area you're updating, will be overwritten.

What happens to previously downloaded areas that I don't visit while updating my copy?
They'll stay the same. The mod does not delete anything from your copy. It only updates the area you are currently in and doesn't touch anything else.

Why the restriction to 160 blocks in each direction? Why doesn't it download the whole world?
The server only sends a certain amount of data.
This is a server-side restriction and my mod can't do anything about that.

Why can't I just put your ZIP-file into my mods folder?
World Downloader is not compatible with ModLoader or Forge ModLoader and probably never will be.

May I use your mod in a modpack?
Yes, do what you want with it.
A link to this thread would be nice though, so that your users can report bugs.

May I use your source code for my own mods?
Yes, do what you want with it.
If you use large amounts of code it would be nice to mention my mod or me somewhere.

Your mod is incompatible with XYZ. Can you provide files with both mods' changes?
Probably, but I don't want to.
This means I'd have to update the files every time XYZ has a new version.
Now imagine I'd also have to do this when mod ABC has a new version, and mod DEF.

Bug Reporting:
If you find any bugs that crash Minecraft PLEASE also add the text from the error report screen. Without that I probably won't be able to help you. Problems can be posted in this forum or on the project's bug tracker at github.

I have been talking with nairol and he asked me to carry on the project since I have been making updates for the last few versions of the mod. He stored his source code at github. I forked that project and have a branch with his unfinished features which I will complete and test. Hopefully it will be ready for an official beta release as binaries in the next week or so. I'm still looking over the code he just pushed yesterday. Thanks for your continued interest in the World Downloader mod.

[Shasharala]

Hmm... I havn't checked with MCEdit or any tools yet... but I download a world... and it just gives me an empty world... and I fall forever...

I have used this tool in the past and it worked...

[leponder]

BTW thank you for continuing this, there's only 3 essential client-side mods I use and this one is one of them. Now if they can just fix Worldedit CUI D:

If you just connect/start download/stop download/open world in rapid order then it might not have a chance to do anything. I would suggest staying connected for at least 10-15 seconds minimum (and move around a little too!). Then, after you disconnect, count to 10 before you open the single player world. I don't know why, but I've heard a few reports of "slow" saving so wait a few seconds before opening the saved world. The 1.3.2 version has been downloaded thousands of times and I have not heard this problem from anyone else on this version.

[Zaraxxas]

I love it so much, wenn I do not only see update requests for a mod, but instead posts of people who updated the mod instead on their own.
So much is only possible through open-source. It makes it possible that the whole community can work together on improving and updating great mods.
Thumbs up!

[SantySc]

Fantastic! this is amazing bro... last week i saw the old version of this mod and really wanted it for 1.3.2, love u!

[Sticky_Slime]

Thank you. I need this mod.

[lordroy]

Thank you for updating this.

What can't be saved?

• The seed value of the world. It is no longer sent by the server.

it is possible to use the /seeds-commando to get the seed. So maybe the addon could grab it from the chat.

Yes. That's how the mod works. Type the /seed command and it will either say you can't do that or it will show the seed and save it. It's in the screenshots at the top of this thread. I clarified the FAQ. Everyone asked for it to save the seed, but it's not typically possible unless you are op. the server just doesn't send it. The new WDL v2 I'll be releasing in a week will be able to grab the seed automatically when permissions allow.

The problem could be with another mod, but I have also seen that problem when I start/stop too quickly. How long are you downloading for between "start download" and "stop download"? Give it 10 or 15 seconds to load from the server and also, move around at lease 15 squares so you are moving from one chunk into another. There is definitely some bug in the mod somewhere but it's rare and I don't know yet what causes it. Give it another try and be patient. It's been downloaded many thousands of times and I've only heard of this problem from 2 people. Is your computer slow or fast?

Worldedit CUI 1.3.2a stops working after World Downloader is installed.
Worldedit CUI is a modloader mod, and doesn't overwrite any base classes.
I tried letting Modloader overwite the conflicting .class files (asv.class and .wl.class are the only 2 conflicts), but Minecraft just crashes when I turn on downloading.
I tried using asv.class from Modloader and wl.class from Downloader, and that seemed to do the trick to make both mods play together. wl.class is NetClientHandler in MCP, is that just the /seed feature?

[Spezialeinheit]

Could not you swap the World Download button with the Disconnect button? I press the wrong constantly :/

[Koorg]

Hi

This mod is cool, but I'd like to use it more like a mapping-only tool, i.e. not being able to see under the surface.

Would it be possible to either :
- only store the 1st non-empty block starting from 255 top-down
- overwrite all non-empty blocks (but not the last) starting from 0 bottom-up
- translate all ore blocks to "Stone" (coal, iron, gold, obsidian, redstone, diamonds, moss stone...)

I know the first 2 options would be very heavy in terms of processing time, but the last one would be sufficient in not offering too much hints.

What would be interesting in terms of ways to avoid too much hinting, the server could avoid sending ore-like information from -160+160 / 0-255, but only send it for -5+5 / -5+5... that would probably increase the number of packets sent from the server to the client, but I guess these would be very small pieces of information... but I guess minecraft devs have accepted the way it is now, because it's not possible to completely avoid hinting.

Just some open ideas...

[muggerfugger]

nice, once thing i hate about playin on other peoples servers is not being able to save my structure. This resolves that thanks
