Break blocks around a breaked block

Recommended Posts

Hi, I made a pickaxe in my mod that I actually want it to break ore veins more easily, so I made a blockbreakevent, and then a script that checks for every block around the ore you broke if there are any blocks of the same type, and if there are, then break them. My script is actually not working, and I don't really know why 😅, so I post this for any help, I would really appreciate it.

Thanks !

 

Here is my event :

@SubscribeEvent
    public static void onBreakEventWithPickaxe(BlockEvent.BreakEvent e) {
        PlayerEntity playerIn = e.getPlayer();
        Item pickaxe = ModItems.NETHER_STAR_PICKAXE.get();
        Block block = e.getState().getBlock();
        IWorld world = e.getWorld();

        if (e.getState().getBlock() instanceof OreBlock && playerIn.getHeldItemMainhand().getItem() == pickaxe) {

            int radius = 3;
            int height = 6;
            int posX = e.getPos().getX() - radius;
            int posY = e.getPos().getY() - radius;
            int posZ = e.getPos().getZ() - (height / 2);

            for (int i = 0; i < radius * 2 * radius * 2 * height; i++) {

                BlockPos pos = new BlockPos(posX, posY, posZ);

                if (world.getBlockState(pos).getBlock() == block) {
                    world.destroyBlock(pos, true);
                }

                posX++;

                if (posX == radius * 2 + 1) {
                    posY++;
                    posX = e.getPos().getX() - radius;
                }

                if (posY == radius * 2 + 1) {
                    posZ++;
                    posY = e.getPos().getY() - radius;
                    posX = e.getPos().getX() - radius;
                }
            }
        }
    }

BlockPos.getAllInBox(...) would be a much, much better way of handling that loop.

Or hell, using three nested loops for x, y, and z...

Okkk, thanks, indeed it was a pain making a such loop 😅, I am trying to find how BlockPos.getAllInBox(...) works, but I don't fully understand :/

Have you got any advice ? 😅

 

I mean, I found out how to create the Stream with the two positions, but how can I use the Stream it creates ?

Ok so I think I figured it out, with a simple foreach loop, but I still can't make it works 😑

 

I made this :

@SubscribeEvent
        public static void onBlockBreakEvent(BlockEvent.BreakEvent e) {
            PlayerEntity playerIn = e.getPlayer();
            Block block = e.getState().getBlock();
            IWorld world = e.getWorld();

            if (e.getState().getBlock() instanceof OreBlock) {

                int radius = 3;

                int baseX = e.getPos().getX() - radius;
                int baseY = e.getPos().getY() - radius;
                int baseZ = e.getPos().getZ() - radius;

                int finalX = e.getPos().getX() + radius;
                int finalY = e.getPos().getY() + radius;
                int finalZ = e.getPos().getZ() + radius;

                BlockPos firstPos = new BlockPos(baseX, baseY,  baseZ);
                BlockPos secondPos = new BlockPos(finalX, finalY,  finalZ);

                Stream<BlockPos> blockList = BlockPos.getAllInBox(firstPos, secondPos);

                for ( BlockPos pos : blockList.collect(Collectors.toList()) ) {

                    if (world.getBlockState(pos).getBlock() == block) {
                        world.destroyBlock(pos, true);
                    }

                }

            }
        }

Stream implements IEnumerable, so you don't need to convert it to a List

But is there a problem with my foreach loop ? when I make it sysout position for every pos of the stream, it prints the same position at all, and I don't really understand why :/

IEnumerable is a C# thing.

Derp yeah.

The Java equivalent would be Iterable, which Stream does not implement.

 

I thought it did. Nevermind then.

you can use the collect() method from the stream, and then pass the desired collection type conversion, in this case Collectors.toList()

yup, I did that, but it isn't working, and when I print the pos for every element of the stream, it prints the same position at all, and I don't understand why
