Solved Remove biomes from the biome generator

I am making a custom world generator so I don't have to use Terrain Control. I don't want to use Terrain Control because it is very resource heavy. The main reason why I don't want to use the vanilla generator is because I wan't to get rid of oceans. I have pretty much everything in my chunkgenerator working, except for one thing: I wan't to completely get rid of ocean biomes. I would prefer to remove them from the biome generation so I don't have to replace them after they have been spawned. How do I do this?

 

I was able to do that slightly differently, but that's not quite what I need. This will replace the biomes I don't want. But that will result in a plains biome the size of a deep ocean

 

@ProJoosh @MiniDigger I am sorry, I didn't properly look at the code. Thanks for helping me out!

 

Code (Text):

            biomesField = BiomeBase.class.getDeclaredField("biomes");
            biomesField.setAccessible(true);

            if (biomesField.get(null) instanceof BiomeBase[]) {
                BiomeBase[] custom_biomes = new BiomeBase[] { BiomeBase.SWAMPLAND };

                biomesField.set(null, custom_biomes);
            }

With this code I still get other biomes than SWAMPLAND. U put this in my onLoad method and have set load: STARTUP in my plugin.yml

 

I did remove the world, and I don't care about 1.9. I have also taken some peeks in the code. However there is a lot of code and many parts I don't understand.

 

I understand what you are saying, but I have no clue how to do this stuff

 

@MiniDigger I got a clue. The reason why the previous code doesn't work is because I am not allowed to set the biome[] because it's final. Can I bypass that?

 

I finally got it working. I had to follow a number of conditions:
- The biomes need to be in the right place in the array (their id as index)
- I need to edit the array which I get in the first place (kindof makes sense knowing java)
and some other things I forget to mention

but here's the working code for future coders:

Code (Text):

        Field biomesField;
        try {
            biomesField = BiomeBase.class.getDeclaredField("biomes");
            biomesField.setAccessible(true);

            if (biomesField.get(null) instanceof BiomeBase[]) {
                BiomeBase[] biomes = (BiomeBase[]) biomesField.get(null);
                for (int i = 0; i < biomes.length; i++) {
                    biomes[i] = null;
                }
                biomes[BiomeBase.SWAMPLAND.id] = BiomeBase.SWAMPLAND;
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

for only swamp, and the rest you can probably find out
