public static CreativeTabs BloodyTabBlock = new CreativeTabs("BloodyTabBlock"){

	public ItemStack getIconItemStack(){
		return new ItemStack(bloodyStone, 1, 0);
	}

	@Override
	public Item getTabIconItem() {
		return null;
	}

 

When I start the game everything is normal but when I try to get to the second page in the Creative inventory, the game crashes.

Why are you overriding this:

public ItemStack getIconItemStack(){
		return new ItemStack(bloodyStone, 1, 0);
	}

There is really no point unless you want to use metadata as your icon-definition.

 

@Override
	public Item getTabIconItem() {
		return InitItems.bloodyStone;
	}

Will make your bloodystone as tab icon.

 

Also - is bloodyStone locally saved? (you have direct reference to it).

 

Have look at super class (CreativeTabs).
