Custom Dimenson with Custom Chunk generator


ErfinderLabyrinth

Recommended Posts

You can do this with datapacks. Your mod is a datapack, just add the files to src/main/resources/data

 

Wiki documenting the worldgen json format:

https://minecraft.fandom.com/wiki/Custom_world_generation

 

A gui for generating datapack jsons in general:

https://misode.github.io/

The vanilla "builtin datapack" if it had been written in json:

https://github.com/misode/mcmeta/tree/data/data/minecraft

 

Each json can be done in java code instead. Just register the corresponding object using the standard forge DeferredRegister/RegistryObject mechanism.

Things like a new ChunkGenerator implementation need to be written in code. You still register the object(s) in the same way and then reference it from your datapack.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

Like I said, you can create your own ChunkGenerator, register it, then use it.

See Mojang's stand up test, DebugLevelSource for something similar to what you describe.

 

Another way is to do something like VoidStartPlatformFeature in a void dimension if you are trying to create some kind of "skyblock". Or you can use a Structure instead.

Hmmm.

You want to modify worldgen, but you don't even know how to register an object in forge?

You are going to break people's worlds. 😞 

 

https://forge.gemwire.uk/wiki/Registration

The ResourceKey you want is the "suprisingly" named:

net.minecraft.core.Registry.CHUNK_GENERATOR_REGISTRY

I know how to do this, but I don't have an entry in ForgeRegistries(Requires the DeferredRegister) and I can't pass a ChunkGenerator in the ResourceKey variant

From the link I posted above:

Quote

Most objects that are known within the game are handled by a Vanilla Registry or a Forge IForgeRegistry

 

Forge expands Vanilla's registries to add important features for modded environments, such as world saving of integer ids and network syncing of integer ids, to ensure consistency when different mods and entries are present.

There is no need to add those extra features for chunk generators so you just use the vanilla resource key.

All this effort over something that is 2 or 3 lines of code.

Other people seem to be able to work it out just fine?

I dont know, that i can use A Registry Object in a DefferedRegister.
Another question about the codec: Can I also say that the constructor does not require a value

And how I create the Level? Which LevelType(Level, ServerLevel, ClientLevel) must I use and which Varialbles do I have to pass

It is you that specifies how the chunk generator gets constructed in the codec you register.  i.e. which parameters it needs either from the json or other sources

Compare for example the previously mentioned DebugLevelSource that takes a single (hardcoded) biome vs the full NoisedChunkBasedGenerator that takes a BiomeSource and noise settings.

If you want a codec that takes no parameters look at for example the NoneFeatureConfiguration.CODEC

Codecs in general:

https://forge.gemwire.uk/wiki/Codecs

 

You don't create the level. The level uses you based on your generator being configured for the Dimension/WorldPreset.

I don't see the point of providing you with links to documentation if you don't read them.

Here's an example from the vanilla datapack I linked to earlier:

https://github.com/misode/mcmeta/blob/e7034dbd1f202250fbae9e6e155a5d76e3d30450/data/minecraft/dimension/the_end.json#L4

or this is how that DebugLevelSource is specified in a WorldPreset

https://github.com/misode/mcmeta/blob/e7034dbd1f202250fbae9e6e155a5d76e3d30450/data/minecraft/worldgen/world_preset/debug_all_block_states.json#L6

 

You have now reached my limit of wanting to help you.

You seem to expect to be treated like a baby. i.e. you want me to feed you with a spoon instead of you feeding yourself.

Vor 59 Minuten sagte Warjort:

Hier ist ein Beispiel aus dem Vanilla-Datenpaket, das ich zuvor verlinkt habe:

https://github.com/misode/mcmeta/blob/e7034dbd1f202250fbae9e6e155a5d76e3d30450/data/minecraft/dimension/the_end.json#L4

oder so WIRD this DebugLevelSource in Einem WorldPreset angegeben

https://github.com/misode/mcmeta/blob/e7034dbd1f202250fbae9e6e155a5d76e3d30450/data/minecraft/worldgen/world_preset/debug_all_block_states.json#L6

 

Sie haben jetzt meine Grenze erreicht, Ihnen helfen zu wollen.

Sie scheinen zu erwarten, wie ein Baby behandelt zu werden. dh du willst, dass ich dich mit einem Löffel füttere, anstatt dass du dich selbst fütterst.

Thanks

    • Me and my friend started a server using Better Minecraft and added about 10 mods on top of it. Everything works fine until we hover over any armor item in the game. Doesnt matter what mod its from it just crashes. We can hover over armor in JEI but it just gives us a tooltip error. Here is my crash message after hovering over armor The game crashed whilst rendering screen Error: java.lang.NullPointerException: Registry Object not present: feathers:lightweight Here is my Crash Report https://pastebin.com/FWQ7n3HS
    • I am unable to resolve my current issue, I have successfully downloaded the forge extension. I downloaded the correct Java link with Javafix included. I log into the game and it shows the "forge" launcher active menu. I double checked to make sure it was the right release number of minecraft and it matched the forge download as well, this also including the most recent forge client. The issue is when I go into a new minecraft server it doesn't allow me to do //wand. No matter what I try the same issue is following me, it almost seems as if the client is fully active but something isn't allowing it to run on my computer. I would appreciate some assistance regarding my problem.   Thank you
    • Came here for the same reason. But for me it's the client. After following your instructions with the jar, I ended up with the following error.
