Need help to build a dimension like a SuperFlat World

[Fel486]

Hello, guys. I've created a new dimension for my server extending from WorldProvider, but no blocks are being generated. So I noticed I need a ChunkGenerator for generate anything I want, such like blocks and structures.

 

I'd like to have a simple example of code that generates a simple map just like SuperFlat World in Minecraft (like on the attachment picture) or some tip on how to start placing blocks or structures.

 

My Dimension and Biome are already registered and works, but most of time I teleported to the dimension it won't load the map, I guess because there's no content.

 

My code: https://pastebin.com/Yt1mEUdL

McJty has an example of a simple chunk provider: https://wiki.mcjty.eu/modding/index.php?title=Tut14_Ep12

 

You could also look at the vanilla chunk generator that generates the flat world.

Thank you, now it's a little better to understand.

 

But I'm getting an error while generating chunks.
