Ok so.  My mod ive made a new World Type and im trying to make it ONLY generator my biome but everytime i run it it loads My biome, roofed forest rivers and oceans.  My goal is to make a custom river biome that instead of water is lava, and a custom ocean that is lava as well but get rid of the roofed forest.  If anyone can help me thatd be appreciated.

{

 

public BiomeGenMYMOD(int id){

super(id);

this.topBlock = Blocks.diamond_block;

this.fillerBlock = Blocks.gold_block;

 

}

 

}

 

The diamond block was just to find it easier
