It's on the server Hypixel (mc.hypixel.net) but it's in their Housing feature, maybe this is the issue? (A dev said housing worlds aren't 'normal' worlds)

I can't find the right log, I have a bunch from yesterday and latest isn't the one.

EDIT: I read the issue and well, the world I want to download has a bunch of item frames. I'll see if disabling them from being downloaded helps.

OK, sounds good. If the issue still happens, grab the log file before you start MC again and it's archived. Can you also get a screenshot of the item frames (possibly with F3 open)? It would be good to know what exactly is in them that might be causing it.

Do you happen to have Skype or so? I really need to use WDL asap.

EDIT: How do I disable item frames? I noticed it downloads almost everything even things I can see far away except the major and most important part which actually has a bunch of item frames.

So, if you can't use the /seed command, you can't get the seed of the world?

Yes. Well, if you have a server op do /seed and give you that value, you can manually insert it in WDL's generator options.

However, note that the seed only really matters if you're generating new parts of the world in single player. If you're just working with one area, it won't matter whether you have the seed.

The server used to send the seed, but that stopped occurring back in Minecraft 1.2.

Okay cool. This looks really awesome and I'd love to give it a try. I want to use it to get the multiplayer world I'm currently playing in, but we have some forge mods added. How do I use this and those mods? I know some people have said to use liteloader, but I don't know how. Could you help elaborate at all? What exactly is liteloader? I'm not sure I understand its function or how it would help add your mod.

EDIT: Okay, after some research I think I've figured it out. However, I keep getting disconnected when I try to join the server :\

Liteloader is another mod loader, similar to forge (basically, it allows loading changes to the game code without manually putting something inside of the .jar file). The reason why it is needed to be compatible with forge is relatively simple. When you install World Downloader as a base / core mod, you overwrite some of the files in Minecraft.jar. However, forge overwrites some of those files too (actually, it uses patches, so it overwrites them but also knows if they were changed beforehand). As such, it doesn't work. Liteloader dynamically edits the needed code so that you can have multiple mods that work with the same section of the code.

Installation of liteloader with forge is described in the main post. Once you've got it installed, just put the liteloader version of the mod in the mods folder (along with your forge mods). Liteloader will load it on startup, and there will be a small tab on the title screen that lists the litemods that are installed.

Note that forge support is pretty incomplete and I can't make any gaurentees as to it working well. If you only have 1 or two mods, it'll probably work, but if you've got a bunch more, it may not. Most notably, I don't think it saves forge's registries properly, so blocks may get mixed up (which... is not good). Improved forge support is something that will be included in the next release.

Hello, I have been recently using the newest version of world downloader for 1.8, but a couple of days ago, it started to crash. I have no idea why it no longer works as i have used it 3 or 4 times with no problem before. I am using the 5zig 1.8, version 3.3 mod with optifine HD U D3 mod and thats all. It used to work with these mods but now everytime I try to world download I crash. If you know a fix please tell me because I like to use 5zig and I would prefer not to use liteloader if possible.

P.S. If you would like me to post a crash log please tell me how to sicne I have never done it before.

I'll definitely need the log. It's relatively easy to get - when minecraft crashes, it should display the log. Copy that, and then put it in the middle of the following text in a new reply.

(PUT CRASH REPORT HERE)

Can you also tell me when it crashes (IE, when the game first starts, when the "Start download" button is clicked, etc)?

(this isnt part of the report) but it happens when I click the stop download button

OK, I can reproduce that. It seems to only occur when optifine is also installed - it looks like optifine modifies some of the same files as WDL (both edit WorldClient).

Not using optifine would solve this. I don't think you want to do that, though. So you could use liteloader. I think liteloader should be compatible with 5zig if installed correctly.

Here's instructions for your case. Note that this is somewhat complicated, but should be doable, and I've added some pictures.

Good luck!

You definitely seem to know your stuff and is dedicated to helping people when they have difficulties with the mod. This worked out great and thank you for that. I encountered no problems and the map loaded perfectly! I was a bit neglected to try lite loader before because I wasn't sure how reliable it was, but now I feel like I can trust it. One more thing, will lite loader work with a modpack per chance? There is this modpack I want to get called JustPvp http://www.justpvp.com/mod/ however, whenever I tried to load it up (you have to download it like 5zig) I launch it from my launcher and it would stop responding on the loading screen. I'm fine if you don't have a solution to this as I am happy with what you have helped me with. The only reason why I wanted the pack itself was the world downloader and a couple other things. The one thing about this modpack though is that you cannot go into the files and extract the mod itself that I know of. If you have a solution then ill be more than happy, and even if you don't, it's fine, I have what somehow broke :D.

P.S. keep doing what you're doing you are very good at it.

Liteloader works with most modpacks (in fact, some use it). However, that mudpack just seems completely broken (I tried installing it as is and it didn't work; I might be able to figure something out but it doesn't feel worthwhile). It seems like it's got a pretty old, half-obfuscated version of WDL. I'd advise not working off of it and instead installing the mods you're interested in manually. If it helps, here's a gamma mod for liteloader (gammabright) and here's a minimap mod for it (VoxelMap).

Why not make the mod compatible with forge?

Why not make the mod compatible with forge?

Liteloader and forge are compatible. However, if you're wondering why we can't have it just loaded directly by forge...

As far as I know (though I haven't researched forge extensively) Forge does not contain the hooks needed to set up this mod. Forge is great for creating mods that add new blocks or extend compatibility, but it isn't very good for tweaking the game.

Note that while it's compatible, things might not be saved properly because forge has a bunch of extra packets that aren't documented very well (and each mod does things differently - hard to handle the format for each tile entity). I'm working on a system for the next release of World Downloader (1.8d) to allow handling custom blocks, but it'll probably be a while.

Are there any specific mods you are interested in?

Thanks for the links but I’ve downloaded world downloader and it works perfectly but I can’t see entities, even while just playing on a server. I don’t know if it is a bug in WDL or if it’s a bug with LiteLoader. Please help!!!

All entities? That seems really odd... Can you post a screenshot (preferably one with the mod installed and one without)? Also, do you have any resource packs installed?
