how to check if Block at X position has changed

[xana43]

so here's the issue at hand. I've made a tile entity that uses the block pattern interface to check if the multiblock that it's part of is complete/valid.

I have it set up so that it checks the structure of the neighbor is changed. but my issue is this

 

 @Override
    public void neighborChanged(final BlockState pState, final Level pLevel, final BlockPos pPos, final Block pBlock, final BlockPos pFromPos, final boolean pIsMoving) {
        super.neighborChanged(pState, pLevel, pPos, pBlock, pFromPos, pIsMoving);

        if(pLevel.getBlockEntity(pPos) instanceof ScannerTileEntity scannerTile)
        {

                //CodeLyokoMain.Log.info("check");
                if(!pLevel.isClientSide()) {
                    scannerTile.check();
                }

            //if(level.getBlockState(pos.above().above()).getBlock() == ModBlocks.SCANNER_TOP.get())
            //{
              //  scannerTile.check();
            //}
        }
    }

it only checks the block RIGHT next to it in all directions

what I want is to check is a radius if any block has changed in these states,  but I am unsure how to check that.

one of the thoughts I've had is to call the super again but change the pFromPos to pFromPos.above()

eg. I had my structure call neighbor updated when it was broken, with a different offset amount, in order to ping the center block about the change.

I almost got it working, I made an interface for both the master tile entity and the blocks that make up the multiblock where when the block is placed it finds the master in an area and then sends the check method I made for it to check if the blocks are valid
