How to create a new world?

[Proxxo]

Hi modders,

 

I want to be able to "clone" parts of the world the player currently stand in. The cloned world should be saved as a new map on the client.

First of, I just want to create a new single player map file. Is this possible with Forge?

I have looked into the article of WorldSavedData but as far as I can say its intention is not to be used to create new worlds.

Also, creating a new world generator does not seem to fit my scenario. I want the new map to be created while the player is in game.

 

Does anyone know how to start? Thanks.

Here's a hint.

You're working in a language that has access to the file system.

Hi Draco,

 

thank you for taking the time to read and post to my question.

Of course I know that I could just copy and paste files with java - do you assume that devs posting questions here don't know that?

 

Perhaps my question was not clear enough.

I am looking for the Forge-way to copy the current and nearby chunks of a player into a new world file.

Is there something like chunk.saveToDisk() or an API to save into .dat or .mca files?

You have no idea what kind of people come here expecting that making a mod is just pushing a few magic buttons in a GUI.

Chunk saving happens via IChunkLoader::saveChunk, which is implemented in AnvilChunkLoader. You can probably get away with instantiating your own, pointing it at whatever directory you want and then saving the chunks you need.

Yeah, I am probably spoiled by stackoverflow.com.

Some people dont seem to understand you need Java knowledge before being able to program Java, but we dont need to forget to respect everyone who tries to learn java at least, and i am helping people not only with things i know, but i use the things i know to solve others problems, they all seem to forget this is a helping For rhe Forgde sources and not for java, they can better go to codecademy, stackoverflow or sololearn, and also stackoverflow will help them. Creating errors helps you prograss further in programming, never be scared of some typ of code and be never scared of asking a question: No question ever was stupid.

 

why am i writing this? well, because i want to let evryone know that this forum needs java knowledge but you aint dumb if you ask questions about forge

Sometimes if you have a slight hint of vanilla, that's okay.
