[Forge 1.10.2] Create a pickaxe that break unbreakable blocks?

[lethinh]

Does anyone know how to create a pickaxe that break unbreakable blocks?

[Animefan8888]

Use the PlayerEvent.HavestCheck event and the PlayerEvent.BreakSpeed event.

I already know that. And I am doing an pickaxe that mine 10x10 blocks. Base on the TerraPick in Botania. But I am asking how to do that (in the event). My unfinished code:

@SubscribeEvent
    public void onPlayerDig(PlayerInteractEvent event) {
        if (event.getFace() == null || event.getWorld().isRemote
                || event.getEntityPlayer().applyPlayerInteraction(event.getEntityPlayer(),
                        event.getEntityPlayer().getForward(), event.getItemStack(),
                        event.getHand()) == EnumActionResult.PASS
                || event.getEntityPlayer().getHeldItem(event.getHand()) == null
                || event.getEntityPlayer().capabilities.isCreativeMode)
            return;
        IBlockState state = event.getWorld().getBlockState(event.getPos());
        Block block = state.getBlock();

        Random random = new Random();
        if (block.getBlockHardness(state, event.getWorld(), event.getPos()) <= -1 &&
                event.getEntityPlayer().getHeldItem(event.getHand()).getItem() == LudicrousItems.infinity_pickaxe &&
                (block.getMaterial(state) == Material.ROCK || block.getMaterial(state) == Material.IRON)) {
                LudicrousItems.infinity_pickaxe.onBlockStartBreak(event.getEntityPlayer().getHeldItem(event.getHand()),
                        event.getPos(), event.getEntityPlayer());
             } else {
                ItemStack drops = block.getPickBlock(state,
                        ToolCommons.raytraceFromEntity(event.getWorld(), event.getEntityPlayer(), true, 10),
                        event.getWorld(), event.getPos(), event.getEntityPlayer());
                if (block.quantityDropped(random) == 0) {
                    if (drops == null)
                        drops = new ItemStack(block, 1, block.getMetaFromState(state));
                    dropItems(drops, event.getWorld(), event.getPos());
                } else
                    block.harvestBlock(event.getWorld(), event.getEntityPlayer(), event.getPos(), state,
                            event.getWorld().getTileEntity(event.getPos()), drops);
                event.getWorld().setBlockToAir(event.getPos());
                event.getWorld().playEvent(2001, event.getPos(),
                        Block.getIdFromBlock(block) + (block.getMetaFromState(state) << 12));
            }
        }
    }

• Don't subscribe to the raw PlayerInteractEvent. Choose one of the sub-events.
• Why are you calling applyPlayerInteraction like that? It makes no sense, you are telling the player to interact with itself. 
• getForward is annotated with @SideOnly(CLIENT), which means you cannot use it in common code like this. You can learn more about sides in the documentation.
• Why are you creating a new Random instance every time?
• Block::getBlockHardness is deprecated, you should use IBlockState::getBlockHardness instead.
• hardness <= -1 is not the condition for unbreakable. A block is unbreakable if it's hardness is below 0.
• In 1.10.2 ItemStacks can still be null hence you cannot simply call getItem on the result of EntityPlayer::getHeldItem, since it might be null.
• Block::getMaterial is deprecated, use IBlockState::getMaterial instead.
• Why are you doing a ray-trace? You know which block was hit and you can also obtain the hit vector needed to create the RayTraceResult from the event.
• You should not be calling quantityDropped, it is not accurate for all blocks. The only way to truly obtain a block's drops is to call Block::getDrops.
• You should almost never call Block::getMetaFromState, especially not to construct an ItemStack.
• Use Block.getStateId instead of manually constructing the ID from metadata.

Still doesn't work. Here is my newest code:

@SubscribeEvent
    public void onPlayerMine(PlayerInteractEvent.LeftClickBlock event) {
        if (event.getFace() == null || event.getWorld().isRemote
                || event.getEntityPlayer().getHeldItem(event.getHand()) == null
                || event.getEntityPlayer().capabilities.isCreativeMode)
            return;
        IBlockState state = event.getWorld().getBlockState(event.getPos());
        Block block = state.getBlock();
        if (state.getBlockHardness(event.getWorld(), event.getPos()) < 0 &&
                event.getEntityPlayer().getHeldItem(event.getHand()).getItem() == LudicrousItems.infinity_pickaxe &&
                (state.getMaterial() == Material.ROCK || state.getMaterial() == Material.IRON)) {
                LudicrousItems.infinity_pickaxe.onBlockStartBreak(event.getEntityPlayer().getHeldItem(event.getHand()),
                        event.getPos(), event.getEntityPlayer());
            } else {
                ItemStack drop = block.getPickBlock(state,
                        ToolHelper.raytraceFromEntity(event.getWorld(), event.getEntityPlayer(), true, 10),

Can you use the code tag please? (<>)that thing. Currently I cant even tell what you are doing

[CrazyGriefer1337]

Just try the following:

-Test if the block is unbreakable (Bedrock, or something modded)

-If yes, execute the command "fill" (Minecraft command, not Java)

-If it doesn't work, throw your PC out of the window.

• I am still not clear as to why you are calling onBlockStartBreak. If anything you need to completely emulate the block-breaking process as it normally occurs in PlayerInteractionManager.
• You are still ray-tracing without the need to do that.
• Block::getDrops will never return null.
• You are still calling Block::getMetaFromState.

Here is my final newest code: https://gist.github.com/anonymous/28b892b90e2f73d2242a3f2b077e77ca

[Draco18s]

On your newest code....

• You are comparing ItemStack instances using == which will never work.
• Except that what you are comparing is the return of block.getItem(world, pos, state)  with the return of block.getItem(world, pos, state) (i.e.. itself) which will always be true.

You should not construct the dropped item stacks manually. Use Block::getDrops to obtain the drops, like I already said in my first post.

Expand  

I can't. Block::getDrops is List<ItemStack> but the drop is a item stack.

So return a list that contains just one stack.

Can't be. If I do that, the method InventoryHelper::spawnItemStack and Block::harvestBlock WILL NOT WORK

• Now you are comparing a List<ItemStack> to an ItemStack, so the result will always be false. Why are you making this comparison anyway? What result are you actually trying to get?
• You still keep using ==, which only checks for the exact same object, rather than for meaningfully equivalent objects. Two different ItemStacks made of the same Item and stacksize will not be equal with the == operator.

List<ItemStack> drop = new ArrayList<>()

...

if (drop == null)

• How could drop possibly be null here after you have set it to a new ArrayList? (Hint: it couldn't).

You seem to be having trouble with some fairly fundamental Java/OOP concepts, you might be better off learning some general programming first.

I have just learned java for few months. And the code didn't work:

 

@SubscribeEvent
public void onPlayerDig(PlayerInteractEvent.LeftClickBlock event) {
    World world = event.getWorld();
    EntityPlayer player = event.getEntityPlayer();

    if (event.getFace() == null || world.isRemote || StackUtils.isEmpty(player.getHeldItem(EnumHand.MAIN_HAND)) || player.isCreative())
        return;

    BlockPos pos = event.getPos();
    IBlockState state = world.getBlockState(pos);
    Block block = state.getBlock();
    List<ItemStack> drop = new ArrayList<>();

    if (drop == null)
        drop = new ArrayList<>(block.getDrops(world, pos, state, EnchantmentHelper.getEnchantmentLevel(Enchantments.FORTUNE, new ItemStack(this))));

    block.harvestBlock(world, player, pos, state, world.getTileEntity(pos), new ItemStack(block));
    InventoryHelper.spawnItemStack(world, pos.getX(), pos.getY(), pos.getZ(), new ItemStack(block));

    world.setBlockToAir(pos);
    world.playEvent(2001, pos, Block.getStateId(state));

You're still doing this pointless check. And now you do nothing with the drop variable after you create it anyway.

 

When you say the code doesn't work, please be more specific. Exactly what does and doesn't happen, and what are you expecting to happen? At this point I've lost track of the problem.

It doesn't break unbreakable block. That's the point of the code.

[Draco18s]

 List<ItemStack> drop = new ArrayList<>();

Cool, I have an array object

if (drop == null)

Nope, it's not null. It's an ArrayList of size zero.

block.harvestBlock(world, player, pos, state, world.getTileEntity(pos), new ItemStack(block));
InventoryHelper.spawnItemStack(world, pos.getX(), pos.getY(), pos.getZ(), new ItemStack(block));

And now, I ignore the fuck out of my array object.

Does it break ordinary breakable blocks? Does the game crash? Does the event get called?

It breaks ordinary breakable blocks. The game doesn't crash. And I have called the event by using MinecraftForge.EventBus::register
