I'm toying with adding a dimension to my mod. I'd like the dimension to be from an existing limited map, no seed/generation rules needed. Picture a sky island, for example.

 

Before I start writing a custom IWorldGenerator to solve this, I thought there might be a solution, or a way to simplify the process.

 

One thought I had was to use a structure_block, maybe subclassed to bypass the 32x32x32 limit.

 

Thanks in advance.

Very cool, thank you!

I just tried doing that, but instead got stuck in a unreal dimension with not any sun or moon, while being console-spammed of that:

[File IO Thread/ERROR] [minecraft/AnvilChunkLoader]: Failed to save chunk

Escaping the dimension and re-entering it results in a complete blank world.

 

Here's the line for getSaveFolder:

@Override
public String getSaveFolder()
{
	return Reference.MODID + ":worlds/wol";
}

Here's the entire dimension file and the world folder.

You need to return the path to a physical folder on disk, not a resource location.

Then it must be assets\mubble\worlds\wol?

So I must copy the dimension worlds files to a temporary location in, for example, .minecraft/mubble/worlds, and then I must copy those files to the world file?

Okay, thanks!

I've done this FileMover class:

public class FileMover
{
	public static Path createTempDirectory(Path dir, String prefix, FileAttribute<?>... attrs)
	throws IOException
	{
		return dir;
	}
}

But then? How do I get the path to the world file itself, at dir in FileMover.createTempDirectory(dir, prefix, attrs);?

Oh okay, misunderstood, got it now. But still, how may I find the world file and put it as dir in Files.createTempDirectory(dir, prefix, attrs);?

Yes, but I want this directory to be the dimension folder that is directly put into the world folder itself.

What? What "world folder"?

.minecraft\saves\<world>

So I can put the dimension world directory in .minecraft\saves\<world>\DIM64 (as my dimension's ID is 64)

No, I want to have a dimension but it's actually a pre-built map. I want to copy the dimension world files I got in the .jar to the world directory so I can actually load the map.

Completely editable, changes persists, like a normal dimension, but the base map is already built.

Yes, then you have to copy it to the folder before creating the dimension.

Then I must copy the files to .minecraft\saves\<world>\DIM64, am I right?

That would be the default location, provided your dimension ID is 64 (it should be configurable).

Yes, sure, that's what I want.

public final class CopyFiles
{
	public static void toWorld(String FROM_s) throws IOException
	{
	    Path FROM = Paths.get(FROM_s);
	    Path TO = DimensionManager.getCurrentSaveRootDirectory().toPath();
	    CopyOption[] options = new CopyOption[]
	    {
	      StandardCopyOption.REPLACE_EXISTING,
	      StandardCopyOption.COPY_ATTRIBUTES
	    }; 
	    Files.copy(FROM, TO, options);
	}
}

I've made this class, but now I must get the path to my map in the .jar for the var Path, how can I do this?

Hey again!

I actually progressed very well since yetersday and found a way to do it properly, but I still need to solve an issue.

Firstly, here's my new method:

public final class CopyFiles
{	
	public static void toWorld(String dir, String file, int dim) throws IOException
	{
	    Path FROM = new File(new ResourceLocation(Reference.MODID + ":worlds/" + dir + "/" + file).getPath()).toPath();
	    Path TO = new File(DimensionManager.getCurrentSaveRootDirectory(), "DIM-64/" + file).toPath();
	    CopyOption[] options = new CopyOption[]
	    {
	      StandardCopyOption.COPY_ATTRIBUTES
	    }; 
	    Files.copy(FROM, TO, options);
	}
}

But upon loading the world, the game crashes and reports: java.nio.file.NoSuchFileException: worlds\wol\region\r.0.0.mca which I interpretate as an error with the FROM variable. Anything helping would be very cool, thanks in advance.

 

EDIT: Woops, didn't saw the thread had a second page, currently looking at what you said, this very comment is useless, do like if you didn't saw it.

Following what you've said,here's my new-new method:

public final class CopyFiles
{	
	public static void toWorld(String dir, String file, int dim) throws IOException
	{
	    InputStream FROM = CopyFiles.class.getResourceAsStream("assets/mubble/worlds" + dir + "/" + file);
	    //Path FROM = new File(new ResourceLocation(Reference.MODID + ":worlds/" + dir + "/" + file).getPath()).toPath();
	    Path TO = new File(DimensionManager.getCurrentSaveRootDirectory(), "DIM-64/" + file).toPath();
	    CopyOption[] options = new CopyOption[]
	    {
	      StandardCopyOption.COPY_ATTRIBUTES
	    }; 
	    Files.copy(FROM, TO, options);
	}
}

The game crashes, FROM is null.

I don't think I understood how to use getResourceAsStream, could you explain please?

You should use a resource location and look at how vanilla turns them into real paths. You should also use the ResourceLocation constructor that takes a domain and a path, not put it together manually with domain + ":" + path

So at the end, how the FROM variable will look like? I'm sorry, I still don't really understand from which class I must do the getResourceAsStream neither what to put in it.

 

Also, my region folder is located here:

Okay so apparently InputStream FROM = CopyFiles.class.getClassLoader().getResourceAsStream("assets/mubble/worlds/" + dir + "/" + file); seems to work, but now the game crashes because the StandardCopyOption.COPY_ATTRIBUTES is not supported, should I just remove it?

Okay, it works now. For anyone interested, here's my class:

public final class MoveFiles
{	
	public static void copyToWorld(String dir, String file, int dim) throws IOException
	{
	    InputStream FROM = MoveFiles.class.getClassLoader().getResourceAsStream("assets/mubble/worlds/" + dir + "/" + file);
	    Path TO = new File(Minecraft.getMinecraft().gameDir + "/saves/" + Minecraft.getMinecraft().getIntegratedServer().getFolderName(), "/DIM" + dim + "/" + file).toPath();
	    CopyOption[] options = new CopyOption[] { };
	    Path parentDir = TO.getParent();
	    if (!Files.exists(parentDir)) Files.createDirectories(parentDir);
	    if (Files.exists(TO)) return;
	    
	    Files.copy(FROM, TO, options);
	}
}
