[[1.7.2] [Beginner] Store a block w/in a TileEntity / TileEntity in general]

I've solved it, but it seems awfully complicated for such as basic task.

 

Here's my solution:

@Override
  protected void dropBlockAsItem(World p_149642_1_, int p_149642_2_, int p_149642_3_,
      int p_149642_4_, ItemStack p_149642_5_) {
    System.out.println("dropBlockAsItem");
    // super.dropBlockAsItem(p_149642_1_, p_149642_2_, p_149642_3_, p_149642_4_, p_149642_5_);
    // TODO: TEST
    try {
      TileEntityBaseScanner tile =
          TileEntityHelper.getTileEntityBaseScannerFromCoords(p_149642_1_, p_149642_2_,
              p_149642_3_, p_149642_4_);
      ItemStack itemstack = new ItemStack(this, 1);
      itemstack.setTagCompound(tile.getNBTTagCompound());
      itemstack.setStackDisplayName("Test: "
          + tile.getNBTTagCompound().getInteger("test"));
      Entity item = new EntityItem(p_149642_1_, p_149642_2_, p_149642_3_, p_149642_4_, itemstack);
      p_149642_1_.spawnEntityInWorld(item);
    } catch (Exception e) {
      System.out.println("NO entity dropped!");
      e.printStackTrace();
    }
  }

  @Override
  public void onBlockPlacedBy(World p_149689_1_, int p_149689_2_, int p_149689_3_, int p_149689_4_,
      EntityLivingBase p_149689_5_, ItemStack p_149689_6_) {
    if (p_149689_1_.isRemote)
      return;

    try {
      NBTTagCompound nbt = p_149689_6_.getTagCompound();
      if(nbt != null){
        TileEntityBaseScanner tile = new TileEntityBaseScanner();
        //tile.writeToNBT(nbt);
        tile.writeToParByNBT(nbt);
        System.out.println(tile.test);
        p_149689_1_.setTileEntity(p_149689_2_, p_149689_3_, p_149689_4_, tile);
      }
      else {
        System.out.println("No NBT");
      }
    } catch (Exception e) {
      System.out.println("NO entity dropped!");
      e.printStackTrace();
    }

  }

// tile-class
  /**
   * Write values from NBT to this
   * bit of an awkward solution, but since we ain't got no pointers making this more flexible is a pain, so I wrote it static for the time being
   * @param par1: NBTTagCompound
   */
  public void writeToParByNBT(NBTTagCompound par1){
    this.test= (par1.hasKey("test")) ? par1.getInteger("test") : test;
  }

[[1.7.2] [Beginner] Store a block w/in a TileEntity / TileEntity in general]

Hello,

I've successfully stored the blocks's ID w/in the TileEntity - thanks for that!

 

I can't figure out how to store the NBT quite yet. Do you have an example?

 

The breakBlock()-method doesn't seem to interact w/ the player or the ItemStack at all. If I override this, the only benefit would be that I'd be able to prevent removeTileEntity() from being called.

 

So I tried overriding dropBlockAsItem() - but how on earth do I get the NBT from my TileEntity?

 

	@Override
    public void breakBlock(World p_149749_1_, int p_149749_2_, int p_149749_3_, int p_149749_4_, Block p_149749_5_, int p_149749_6_)
    {
        super.breakBlock(p_149749_1_, p_149749_2_, p_149749_3_, p_149749_4_, p_149749_5_, p_149749_6_);
        //p_149749_1_.removeTileEntity(p_149749_2_, p_149749_3_, p_149749_4_);
    }

@Override
protected void dropBlockAsItem(World p_149642_1_, int p_149642_2_, int p_149642_3_, int p_149642_4_, ItemStack p_149642_5_){
	TileEntity tile = TileEntityHelper.getTileEntityBaseScannerFromCoords(p_149642_1_, p_149642_2_, p_149642_3_, p_149642_4_);
	p_149642_5_.setTagCompound()); // 
	super.dropBlockAsItem(p_149642_1_, p_149642_2_, p_149642_3_, p_149642_4_, p_149642_5_);
}

[[1.7.2] [Beginner] Store a block w/in a TileEntity / TileEntity in general]

Hello,

sorry if this is trivial.

 

I've a block which is supposed to store meta data, in my case information about a different block. I can't figure out how to store "a block w/in a block", though...

 

My approach:

public class TileEntityBaseScanner extends TileEntity {
public Block bb = Blocks.diamond_ore;

@Override
public void writeToNBT(NBTTagCompound par1) {
	super.writeToNBT(par1);
	try {
		par1.setByteArray("bb", TileEntityHelper.serialize(bb));
	} catch (IOException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
}

@Override
public void readFromNBT(NBTTagCompound par1) {
	super.readFromNBT(par1);
	try {
		this.bb = (Block) TileEntityHelper.deserialize(par1.getByteArray("bb"));
	} catch (ClassNotFoundException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	} catch (IOException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
}

public class TileEntityHelper {
public static byte[] serialize(Object obj) throws IOException {
	ByteArrayOutputStream out = new ByteArrayOutputStream();
	ObjectOutputStream os = new ObjectOutputStream(out);
	os.writeObject(obj);
	return out.toByteArray();
}

public static Object deserialize(byte[] data) throws IOException,
		ClassNotFoundException {
	ByteArrayInputStream in = new ByteArrayInputStream(data);
	ObjectInputStream is = new ObjectInputStream(in);
	return is.readObject();
}
}

Unfortunately, the block class can't be serialized and there's no "NBTTagCompound.setBlock()"-method...

 

Also, is there any way to store the TileEntity once a block is destroyed? i.e., the player destroys the block and he has the block including the metadata in his inventory?

[[1.7.2] [Beginner] Get a chunk's borders]

Thank you. This did the job:

 

		int x_mod = x % 16;
	int x1_border = x;
	int c = 0;
	while (x_mod != 0 && c <= 16) {
		x1_border++;
		c++;
		x_mod = (x1_border) % 16;
		if (debugPlacer)
			p_149727_1_.setBlock(x1_border, y, z, Blocks.redstone_torch);
	}

[[1.7.2] [Beginner] Get a chunk's borders]

Hey,

beginner here, a short question concerning 1.7.2 I couldn't figure out myself by reading the code or Google.

 

How do I get the current chunk's borders?

 

This is my current approach:

	@Override
public boolean onBlockActivated(World p_149727_1_, int p_149727_2_, int p_149727_3_, int p_149727_4_, EntityPlayer p_149727_5_, int p_149727_6_, float p_149727_7_, float p_149727_8_, float p_149727_9_)
   {
if(p_149727_1_.isRemote) return false;

	int x = p_149727_2_;
	int y = p_149727_3_;
	int z = p_149727_4_;

	Chunk currentChunk = p_149727_1_.getChunkFromChunkCoords(x,y);
	ChunkCoordIntPair CCIP = currentChunk.getChunkCoordIntPair();
	int x_border = CCIP.chunkXPos;
	int z_border = CCIP.chunkZPos;
	int y_border = currentChunk.heightMap[x_border << 4 | z_border]; // TODO: crash; taken from canBlockSeeTheSky
//... 

I did some testing and these coordinates definitely aren't the chunks borders but rather the current block's coords. Also, my y_border-method crashes the game via a ArrayIndexOutOfBoundsException (haven't looked into this too much, as soon as I see bit-shifting my mind crashes as well...).

 

Thanks in advance.
