WorldChunkManager help!

Hey all!

I was looking through a tutorial on making a custom dimension, and I don't know which parts I'm supposed to edit from it, so I came here for help. Can you please tell me which parts I need to edit, and what I need to put in the parts that I need to edit?

 

By the way, don't get mad at me for not having the code inside the code box, because the code button isn't working for me.

GotoLink said:

You edit what you want to change from the "vanilla" world.

That's as precise an answer you can get from that question.

 

But I understand you'd want an answer related to the tutorial, in that case:

If you guys dont get it.. then well ya.. try harder...

What does the code tell you about them?

The two first are variables holding GenLayer's,

The 3rd is a reference to a BiomeCache (I suggest you OPEN the class and read it's code to see what it's about :) )

The last one is a list of biomes to spawn.

 

GenLayer's are pretty advance, as they are used for a lot of things.

I guess the best way to learn about them is to search around some and best of all, to dig into the code.

But I'd believe that to be beyond both your skill and what you are trying to do, although you would be the best to know so yourself :)

 

I'm going to assume you copy->pasted the contents of the tutorial without understanding how and why it works.

If that's the case I would ask you to go back a step and try to learn how it all works before trying to manipulate it.

If you don't understand how vanilla works, then it's rather hard to modify it's behavior isn't it? ;)

Okay I'll ask a more specific question.

What is myGenBiomes, what is myBiomeIndexLayer, what is myBiomeCache, and what is myBiomesToSpawnIn?

 

This should be more answerable.

 

 

Dude !! I can Help you ,

 

You use Eclipse well if so

 

Press Ctrl + click the code you wanna know and it will open declaration for ya

 

Hows that =D

    • Every time you post you post in the wrong subforum and I have to move your thread. Please take the hint. This is broken. You must not return null from this method. Use NetworkHooks.getEntitySpawningPacket. You must also only spawn your entity and start riding it on the server.
    • Sorry about the wait, I managed to fix the issue by loading in one of my server providers presets and stealing the jar from that. Sorry about wasting your time.
    • The first step to this is to see if you can track down the original author and ask if they still have the source and if so, can you look at it
