World Downloader

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

The mod has moved here and will be continued by cubic72.

Thanks for all your support while I was working on World Downloader!

Like World Recorder, but more features. One question, servers won't know if your doing this right, and is it un-blockable? I'm not planning a heist, I just think that players should have rights to a servers world.

This could be kind of dangerous...

I didn't know World Recorder. The server can't detect that/when you download. It's not really "downloading" just saving the data stream for offline use.

edit: It is un-blockable, but the mojang guys could change the way they send the world data. So that invisible blocks (underground) aren't sent at all. I don't know how much more CPU power that might cost on the server side.

edit2: Now that I think more about this... It is blockable for limited areas. The server could send different world data to different player groups like trusted and untrusted groups. I don't know if anyone would like to write that mod though. Looks difficult.

How can it be dangerous to have a local copy of a part of the server world?
Really, I don't play online that often. What's the problem?

edit: So the problem is that griefers etc. could download parts of the world, open it with for example MCedit and look for weak spots in buildings where they could do the most harm?

Well I don't know what to do about that. I could delete the mod again but I've got so much positive feedback on YT and reddit.

I saw this mod today on Reddit, watched your videos on YouTube, and downloaded and installed it. It works great, no bugs (although when I first connected to c.nerd.nu the sky was red and it kept on flashing between blue and red o.o it went away though ) and it saves a whole lot more than World Recorder. Keep up the good work!

This mod is pretty fucking epic if i do say so myself. Keep up the good work!

hello, i'd like to use this mod, but the download link doesnt work for me :-(.

[AlfieSR]

Does this require anything like modloader or is it self-contained?

This will be incredibly useful for saving my wool-based projects from Dan's server before some dick burns them down. I know that will happen.

YEEES! finaly my dream mod has come, THX !!!!!

No modloader required.
Should I have used modloader? I'm new to modding Minecraft.
And I've read that modloader doesn't work if the original class files have to be overwritten. (?)

I'm working on that...
Once I figure out how to use Github the problems should be gone.

Btw, the DL link works for me at the moment.

Additionally, people can use tools to find where all the valuable ores are, and go to the server and dig straight to them. But in any case, it's good to see this working.. I'll test it sometime later.

I don't exactly know how this mod works, but depending on how it does someone could spam download and get tons of server lag for everyone else.

This is fantastic!  I'd been trying to use World Recorder, but the latest version constantly causes my game to crash.  Looking forward to test this baby out.

From the OP:

"The mod will not cause any additional load on the server because it never actively requests anything. It lets Minecraft do all the loading and buffering and then right before MC overwrites a buffered chunk that is no longer needed, it saves this chunk to disk. This will only slow down the client a bit when your HDD is too slow. It also saves the complete chunk buffer when stopping downloading or disconnecting."

Ok, that was the only problem I had with this mod, and I guess I didn't quite read the OP to it's fullest.

[SpitefulFox]

That is not what my world looked like. >_>

For some reason, the mod keeps writing gigantic holes in the world in areas that I definitely visited.  In this case, it had made some holes, and I went back online to try and fill them in and it overwrote the main area of the server with a gigantic hole where the map was just fine before.

Edit: Whoops, missed the part where you mentioned that in the bugs section.

It's pretty simple. I'm patching the multiplayer chunk saving methods to actally save the chunks instead of doing nothing.
The code is on Github.
I used MCP 3.1.1 in case you don't have the original files.

If you have questions about the code, just ask.

[Seegggaaaaa]

WOW that work perfectly! THANKS SO MUCH!!! i now have my huge city i made on the xaldin server as a regular map
