How does cave generation work?

[The_DarthMoogle]

Pretty much as the subject.

My idea is to have ores spawn roughly as they would do in real life - for instance coal would occur in sheets, and have natural caves with lots of flowing water in them. Iron/copper/tin would be roughly scattered in plains biomes, and therefore quarrying or strip mining would be the most efficient way to gather them. Gold and silver would sit on river beds and under mountains, and diamonds would spawn along the walls of a cave within a mountain (so actually at ground level)

Would editing minecraft's terrain generation manage this, and where would I begin to mess around with all the code?

You might wanna take a look at other mods for terrain gen other people made, and look how they did it.

Looks like the one you need to start with is BiomeDecorator.java , I only took a which look at things.

However, tekkit uses some forge classes to generator many ores, like copper, tin, silver. So you need to change how it generates its ores as well.

The actual caves themselves are generated after all the ore/dirt/stone is, and simply delete blocks. Its an entirely separate piece of code.

So you're saying that you should totataly rewrite the entire code for world generation?

1. look what terrafirmacraft had to do

2. bash head against desk repeatedly

3. look at vanilla generation

4. bash head again

5. repeat until ready to serve
