Only dirt Minecraft world creation?

[chadandersen1 0]

Recently I've been interested in creating a mod pack, and my idea for the mod pack includes the need for an all-dirt world with no other block generation what-so-ever except for a layer of bedrock on the bottom. If all else fails I can do a super flat with 64 layers of dirt but I'd really like to use some terrain. I've looked at COFH World and Open Terrain Generator but I'm not sure if I can use either of these to do my world gen. I want absolutely no ores, no foliage, no modded structures, and no water/lava pools with a single biome, preferably plains. Is there a good way to make a world like this? I only need the world once, since I plan on using perfect spawn point mod and hardcore world reset to use the same save over and over. Any help would be appreciated, whether a mod can do this or just a save. Thanks!

You’d probably want to use a core mod to modify Minecraft’s world generator to only generate dirt

Don't! Coremods should never be used.

 

I think you can do this by making your own world type and removing the other ones, making yours the only one available.

I think it would be pretty easy. I've done this several times before for testing purposes. I made a tutorial for a single-biome custom dimension here: http://jabelarminecraft.blogspot.com/p/minecraft-modding-custom-dimension.html

 

My tutorial links to full working example of a "cloud world" where all the terrain is built up of "cloud" blocks (on top of a layer of bedrock). I still do some feature, decoration and structure generation but it should be easy for you to figure out where that is happening and simply replace the code.

 

The general idea is that the chunk generator generates the terrain first as bedrock then a "filler block". You just need that to be dirt. Then in all the other "populate", and "decorate" methods you would just do nothing.
