like what biomes? so I can make and exception?

Pretty much all of the non-hills biomes. Plains, forest, birch forest, ice plains...

Average ground height is considered to be 63.

small question, what is the method that makes mobs leashed or un leashed?

This does not generate underground due to these lines.

This line makes the chance of it spawning 1 in 120.

This line makes the chance harder if it was underground, but since it is above ground this works.

Update tell me please what's wrong with it.

public void generateNestUnderground(World world, Random random, int chunkX, int chunkZ, Random rand) {
       int x = chunkX * 16 + random.nextInt(16);
       int z = chunkZ * 16 + random.nextInt(16);
       int xy = x >> 4;
       int zy = z >> 4;
       int y = random.nextInt(43 - 30);

           if(world.getBiomeForCoordsBody(new BlockPos(x,y,z)).getBiomeClass().equals(BiomePlains.class)) {

               if((random.nextInt(45) + 1) <= 1) {
                   boolean place = true;

                   for(int Y = 0; Y < 6; Y++) {
                       for(int Z = 0; Z < 9; Z++) {
                           for(int X = 0; X < 11; X++) {
                               if(world.getBlockState(new BlockPos(X + x, Y + y + 1, Z + z)).getBlock() != Blocks.AIR) {
                                   place = false;
                               }
                           }
                       }
                   }

                   if(place) {
                       dragonNest.generate(world, random, new BlockPos(x,y,z));
               }
           }
       }
}
}

This part checks to see if a 9x11xHeight space is AIR. Which will almost never happen underground.

9X11 more or 9X11 less? I mean does it really needs that the ground is exactly 9X11?

Edit: bigger than 9X11 or less than 9X11 needed to spawn?

That piece of code is entirely useless for your means. You are checking if a 9x6x11 space is AIR. You don't want to do that.

ok gonna do a size count on my structure, my structure is a pretty small dragon nest that can fit in a cave.

the dragonNest.generate(world, random, new BlockPos(x,y,z)); issue tho, did I did the right thing by putting null on

if(place) {
dragonNest.generate(world, random, null); because I did not use it?

Could you post your DragonNest class? I'm pretty sure you are going to need that BlockPos.

here's an update

So what is the problem currently?

still not spawning.

Are you sure it is not spawning lets run through a checklist.

It will only spawn in the Plains Biome.
Then after that it will only have a chance to spawn 1 out of 10 times.
Where it generates underground has to have enough air blocks to generate.
The generation will only run on new chunks.

Make sure you are meeting all of those requirements when you are looking.

I am using a seed that spawns you in a plains biome

I saved that seed so everytime I create a new world, I don't have trouble looking for a plains biome.

The biggest problem is the third bullet point.

Since most of underground is not Air the likely hood of it being like that is really low. it is less than 1%.

the new generate method I use will still not work? I thought I changed the value to 3, 7, 7,

3 * 7 * 7 = 147. 147 blocks will have to be air at the randomly generated BlockPos. The likely hood of this happening is almost 0%. Just remove

                   if(place) {

None of this is needed.

but my structure is not a big ass dungeon, it will not be found easily because miners in survival can't see it in caves that's why It needs a cave.
