I am using the code

        			worldIn.destroyBlock(pos.add(0, 0, i), false);

(i being a variable) to destroy multiple blocks at once. The blocks are being removed but aren't updating, still showing as what they were before until I relog. How can I force a block update at the location?

Are you calling this ONLY (!world.isRemote) server side?

Yes, here is my whole code for the action.

    public EnumActionResult onItemUse(ItemStack stack, EntityPlayer playerIn, World worldIn, BlockPos pos, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ)
    {
        if (!worldIn.isRemote) {
        	for (int i = 0; i < 2; i++){
        			if (worldIn.getBlockState(pos.add(0, 0, i)).getBlock().equals(Blocks.STONE) && playerIn.canPlayerEdit(pos.add(0, 0, i), facing, stack)){
        			worldIn.destroyBlock(pos.add(0, 0, i), false);
            			//worldIn.getBlockState(pos.add(0,0,i)).getBlock().removedByPlayer(worldIn.getBlockState(pos.add(0,0,i)),
            					//worldIn, pos.add(0,0,i), playerIn, true);
        			worldIn.scheduleBlockUpdate(pos, worldIn.getBlockState(pos.add(0,0,i)).getBlock(), 1, 100);
        			}
        	}
        }

The first block is the only one that actually gets updated and is shown breaking. The second one does not update.

Why are you calling scheduleBlockUpdate?

To attempt to update the block since it is broken but doesn't update until relog. Is there another thing I could use?

destroyBlock alone should be enough.

destroyBlock alone doesn't update.

Just tried it, works just fine with just

destroyBlock

Mine's done on right click, if that changes anything.

   
public EnumActionResult onItemUse(ItemStack stack, EntityPlayer playerIn, World worldIn, BlockPos pos, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ)
    {
        if (!worldIn.isRemote) {
        	int dir = MathHelper.floor_double((double)((playerIn.rotationYaw * 4F) / 360F) + 0.5D) & 3;
    		if (dir == 0){
        	for (int i = 0; i < 2; i++){
        			if (worldIn.getBlockState(pos.add(0, 0, i)).getBlock().equals(Blocks.STONE)){
        			worldIn.destroyBlock(pos.add(0, 0, i), false);
        			}
        			if (worldIn.getBlockState(pos.add(1, 0, i)).getBlock().equals(Blocks.STONE)){
        			worldIn.destroyBlock(pos.add(1, 0, i), false);
        			}        			if (worldIn.getBlockState(pos.add(-1, 0, i)).getBlock().equals(Blocks.STONE)){
        			worldIn.destroyBlock(pos.add(-1, 0, i), false);

        			}
        		}
    		}
        }
	return null;
    }

EDIT: Longer gif

Why in god's name are you returning null?

Just changed it to return SUCCESS and it worked. Thank you so much!
