Override core functionality?

[Dronus86]

I'm wondering if there's a way to override/remove parts of vanilla minecraft using forge.

 

For a more poignant example, how would I halve the amount of gold ore that spawns? Or make gold ore only spawn ABOVE y=32? Or similar things?

 

The only thing I can think of is to overwrite all the existing ore in each chunk and re-spawn it all according to my rules, but that seems clumsy and messy.

It all depends on what you wanna do, with the new CoreMod functionality of fml, you can do whatever the hell you want, its just difficult and not for the newbie cooder.

Well for your Gold Ore example, what I suggest you do is generate stone where there are Gold Ores and then regenerate the Gold Ores to your specifications (like 32+ Y). Although, that depends if user generated ores/blocks are called after the vanilla blocks.

 

That might be the clumsy and messy method you've mentioned, but its a way that can work without touching any Vanilla classes, which is always a plus.

LexManos, I am indeed a newbie to FML and somewhat to java/OOP, but I have non-java coding experience (mostly C), so I feel pretty good. Thanks for the heads up, I'll definitely look into that!

 

And yeah, GeoffNukem, that is what I was talking about, but thanks for the suggestion anyway!
