My question is very simple: is there any documentation anywhere on creating a custom world type for 1.7.10? I've found a lot of tutorials for previous versions but they don't seem to work for this version. I've also tried looking through the Biomes O Plenty source code, but was unable to glean anything useful from it because it's such a huge mod and I don't even know where to start. Can anybody shed some light on this topic?

So dimension with everything from total base?

There is GitHub with all code (for 1.7.10).

To my knowledge, dimensions are different from world types, but I'll still have a look at that and see if it can help me.

Well, there is not much to say about WorldTypes.

 

You can make new class that extends WorldType and simply initialize it.

    public WorldType MYCUSTOM = new CustomWorldType(ID, "customName", versionInt);

 

That is all. Note that Minecraft allows you to have 16 WorldTypes, from which few IDs are alredy taken.

Forge automatically extends the limit using ArrayCopy. Since WorldType is only effective on server side, there is theoretically no limit for WorldType. So don't worry about that.
