Attempting to create border and check region inside

[Suncurve]

Hi,

I've created a custom block (Called "Town Hall Block") and managed to detect when it's placed (using a setPlacedBy override)

I'm still quite new to modding with forge, and essentially, what I'm trying to do is create a region (64 blocks in each direction, with the town hall being the center), and be able to search that region for a specific block.

So far, I've got this: (borderDist is an int with a value of 64)

 @Override
    public void setPlacedBy(Level pLevel, BlockPos pPos, BlockState pState, @Nullable LivingEntity pPlacer, ItemStack pStack) {
        if (pLevel.isClientSide()) {
            System.out.println("Block Placed");

            // Calculate Village Borders
            BlockPos borderNorth = pPos.north(borderDist);
            BlockPos borderSouth = pPos.south(borderDist);
            BlockPos borderEast = pPos.east(borderDist);
            BlockPos borderWest = pPos.west(borderDist);

        }

        super.setPlacedBy(pLevel, pPos, pState, pPlacer, pStack);
    }

 

The part I'm struggling with (I've done some research but couldn't find anything) is actually creating that region around the town hall block, and then working out if there's a block of a specific type there, but most importantly, actually working the region out.

Does anyone know what's the right way to do this? Thanks.

There are some static methods in BlockPos that help you do this.

e.g. look at how vanilla's AnimalPanic uses BlockPos.findClosetMatch() to find a water block in lookForWater().
