[1.7.2] Mod ores not generating


Recommended Posts

I have a mod in which I want to add ores that generate in the world. I have done everything I believe is needed to be done (made ores, made an IWorldGenerator that generates the ores, and registered the generator) but when I test it none of the ores spawn.


Main mod file:

@Mod(modid = "ores", name = "Ores", version = "0.0.1")
public class OresMod 
static final String TEXTURE = "ores:";

static Block tinOre = new BlockOre(),
	  		 copperOre = new BlockOre(),
	  		 leadOre = new BlockOre(),
	  		 uraniumOre = new BlockOre(),
	  		 nickelOre = new BlockOre(),
	  		 silverOre = new BlockOre(),
	  		 osmiumOre = new BlockOre();

static Item tinIngot = new Item(),
	 	    copperIngot = new Item(),
	 	    leadIngot = new Item(),
	 	    uraniumIngot = new Item(),
	 	    nickelIngot = new Item(),
	 	    silverIngot = new Item(),
	 	    osmiumIngot = new Item();

public static void initializeBlocks()
	tinOre.setHardness(3.0F).setResistance(5.0F).setStepSound(Block.soundTypeStone).setBlockTextureName(TEXTURE + "oreTin").setBlockName("oreTin").setCreativeTab(CreativeTabs.tabBlock).setHarvestLevel("ItemPickaxe", 2);

     * Adds an Ore Spawn to Minecraft. Simply register all Ores to spawn with this method in your Generation method in your IWorldGeneration extending Class
     * @param The Block to spawn
     * @param The World to spawn in
     * @param A Random object for retrieving random positions within the world to spawn the Block
     * @param An int for passing the X-Coordinate for the Generation method
     * @param An int for passing the Z-Coordinate for the Generation method

     * @param An int for setting the maximum Z-Coordinate values for spawning on the Z-Axis on a Per-Chunk basis
     * @param An int for setting the maximum size of a vein
     * @param An int for the Number of chances available for the Block to spawn per-chunk
     * @param An int for the minimum Y-Coordinate height at which this block may spawn

tinVS, tinOC, tinSL, etc. are vein-size, occurrence, and spawn-levels, all gathered from a config.
