How to make a world gen rarer? [1.7]

[HappleAcks]

So I have a structure that I am generating, but it is too common. Changing the "chunkX * 16, chunkZ * 16" to "chunkX * 128, chunkZ * 128" makes it rarer but also generates super super slowly.

 

      @Override
        public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider)
        {
            switch (world.provider.dimensionId)
            {
            case -1:
                generateNether(world, random, chunkX * 16, chunkZ * 16);
            case 0:
                generateSurface(world, random, chunkX * 16, chunkZ * 16);
            case 1:
                generateEnd(world, random, chunkX * 16, chunkZ * 16);
            }
        }
        
        
        private void generateEnd(World world, Random random, int x, int z)
        {
     
        }
     
        private void generateSurface(World world, Random random, int x, int z)
        {
       
        }
        
        private void generateNether(World world, Random random, int x, int z)
        {
        	//Nethengeic Pit Coords//
            int Xcoord = x + random.nextInt(16);
            int Ycoord = 25 + random.nextInt(35);
            int Zcoord = z + random.nextInt(16);
        
            (new NetherTower()).generate(world, random, Xcoord, Ycoord, Zcoord);

So I got it generating but it is far too common.

Just use the random function to reduce the chance, IE:

if(Random.nextInt(5) == 1){
//Generation code
}

This will effectively make it 1/5 as common. (Just change the 5 into whatever you want the denominator of the chance fraction to be)

This is actually what I ended up doing yesterday. Thanks for the tip.
