I have an item, which when interacted with a Block, checks if there are EntityItems around the block using World.getEntitiesWithinAABB(EntityItem.class, aabb). If the EntityItems contain a certain type of ItemStack (checked with EntityItem.getEntityItem()) then it sets a flag which will be later used. However, when compared to an ItemStack, it always returns false. I am dropping the correct items near the block, and have verified that it knows the items are there by checking the ItemStacks around using println. This leads me to believe that there is a problem with the check.

 

Amalgamite.java (snippet, item)

@Override
    public EnumActionResult onItemUse(ItemStack stack, EntityPlayer playerIn, World worldIn, BlockPos pos, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ) {
    	if (worldIn.getBlockState(pos).getBlock() instanceof Amalgamator) {
    		EntityItem ironIngots = null;
    		EntityItem wool = null;
    		
    		if (AncepsUtil.itemsNearby(worldIn, pos, Amalgamator.detectRange)) { // function which checks if items are nearby (self-explanatory)
    			AxisAlignedBB bb = new AxisAlignedBB(pos.getX() - 4, pos.getY() - 4, pos.getZ() - 4, pos.getX() + 4, pos.getY() + 4, pos.getZ() + 4);
    			List<? extends EntityItem> items = worldIn.getEntitiesWithinAABB(EntityItem.class, bb);
    			for (EntityItem i : items) { // start of problem
    				if (!worldIn.isRemote) {
    					if (i.getEntityItem().equals(new ItemStack(Items.iron_ingot, )) {
    						System.out.println("iron success");
    						ironIngots = i;
    					} else if (i.getEntityItem().equals(new ItemStack(Blocks.wool, 1, OreDictionary.WILDCARD_VALUE))) {
    						System.out.println("wool success");
    						wool = i;
    					}
    				}
    			}
    			
    			if (ironIngots != null && wool != null) {
    				ironIngots.setDead();
    				wool.setDead();
                                if (!worldIn.isRemote) {
    				       worldIn.spawnEntityInWorld(new EntityItem(worldIn, pos.getX(), pos.getY() + 1, pos.getZ(), new ItemStack(AncepsMain.woolyironingot))); // result
                                }
    				return EnumActionResult.SUCCESS;
    			}
    		}
    	}
        return EnumActionResult.PASS;
    }

 

AncepsUtil.getEntityItem()

public static boolean itemsNearby(World worldObj, BlockPos posAt, int detectRange) {
	AxisAlignedBB bb = new AxisAlignedBB(posAt.getX() - detectRange, posAt.getY(), posAt.getZ() - detectRange, posAt.getX() + detectRange, posAt.getY() + detectRange, posAt.getZ() + detectRange);
	return worldObj.getEntitiesWithinAABB(EntityItem.class, bb) != null;
}

ItemStack does not override equals(). You must use stack.getItem() and compare Item instances
