I have declared proper variables in my tile entity

public int px = 0;
public int py = 0;
public int pz = 0;

And minecraft returns nullpointerexception on world.destroy

	public void onBlockDestroyedByPlayer(World world, int par2, int par3, int par4, int par5)
{
	TileEntityBlockZRail tle = (TileEntityBlockZRail)world.getBlockTileEntity(par2, par3, par4);
	world.destroyBlock((int)tle.px, par3, par4, true);
}

What's wrong with that?

If i helped you, don't forget pressing "Thank You" button. Thanks for your time.

Either world or tle is null.

First, do an:

if(tle!=null)
{
world.destroyBlock((int)tle.px, par3, par4, true);
}

If it still shrieks about null, then world is null, which probably would mean You're calling onBlockDestroyedByPlayer some weird way.

Okay, now it doesn't crash, but it doesn't work as i want either. The thing is — i'm placing a couple of blocks at once and i want them to be broken once too, so i...

public void onBlockPlacedBy(World world, int i, int j, int k, EntityLiving entityliving, ItemStack par6ItemStack)
{
   int[][] bl = {{0,1,240},{0,2,224},{0,3,208},{0,4,192},{0,5,176},{0,6,160},
   {-1,1,241},{-1,2,225},{-1,3,209},{-1,4,193},{-1,5,177},{-1,6,161},{-1,7,145},{-1,8,129},
   {-2,2,226},{-2,3,210},{-2,4,194},{-2,5,178},{-2,6,162},{-2,7,146},{-2,8,130},{-2,9,114},
   {-3,6,163},{-3,7,147},{-3,8,131},{-3,9,115},{-3,10,99},{-3,11,83},
   {-4,8,132},{-4,9,116},{-4,10,100},{-4,11,84},{-4,12,68},
   {-5,9,117},{-5,10,101},{-5,11,85},{-5,12,69},{-5,13,53}};
   int dir = MathHelper.floor_double((double)((entityliving.rotationYaw * 4F) / 360F) + 0.5D) & 3;
   world.setBlockMetadataWithNotify(i, j, k, dir, 0);
   for (int l = 0; l < bl.length; l++){
      int[] c = rotxybydir(bl[l][0], bl[l][1], dir);
      world.setBlock(i + c[0], j, k + c[1], RoW.Rails.blockID, dir, 0);
      TileEntityBlockZRail tl = (TileEntityBlockZRail) world.getBlockTileEntity(i + c[0], j, k + c[1]);
      tl.mid = bl[l][2];
      tl.px = i;
      tl.pz = j;
      tl.py = k;
   };
}

It places them rather well, but i want to brake them all too...

You need to make a for loop. Also I would store all positions in a 2D array in all of your TileEntities.

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

A for loop on your block break method.

An (integer) array can be saved in the NBT just fine (i think it's called set-/getIntArray()), else you can also use NBTList for storing arrays... look at the TileEntityChest NBT methods on how to use them.

Uh. I mean, i don't understand the point i should make loop for...

 

You're trying to destroy multiple blocks, so you need to call the destroyBlock method for each block you're trying to destroy.

No i don't. I will destroy main block, it will update nearby blocks, they will check if main block exists, destroy themselves, update nearby and so on. But i'm getting error on world.destroyBlock((int)tle.px, par3, par4, true); line...

Ah, now I see... what error do you get exactly?

This comes when i try to get tl.px...

 

Seems like your TileEntity is null. Mostly it's caused because the block doesn't set one. Can I see the whole block code of yours? Use pastebin.

mah twitter

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

Yeah, when i try

public void onBlockDestroyedByPlayer(World world, int i, int j, int k, int par5)
{
   TileEntityBlockZRail tl = (TileEntityBlockZRail) world.getBlockTileEntity(i, j, k);
   System.out.println(tl);
}

It return null, and for some reason it does that four times. And game does not crash. However, i have tileentityrender class and it reads that data fine without any obvious reason... I think it's something with coordinates...

If i helped you, don't forget pressing "Thank You" button. Thanks for your time.

Hell yeah. That code saved me. 

public void breakBlock(World world, int i, int j, int k, int par5, int par6)
{
TileEntityBlockZRail tl = (TileEntityBlockZRail) world.getBlockTileEntity(i, j, k);
if (tl != null)
{
  world.destroyBlock(tl.px, j, tl.py, false);
}
}

public void onNeighborBlockChange(World world, int i, int j, int k, int par5)
{
TileEntityBlockZRail tl = (TileEntityBlockZRail) world.getBlockTileEntity(i, j, k);
if (tl != null)
{
  if(world.getBlockId(tl.px, j, tl.py) != RoW.Rails.blockID)
  {
   world.destroyBlock(i, j, k, false);
  }
}
}

Now, the only thing i need is my locomotive physics...

If i helped you, don't forget pressing "Thank You" button. Thanks for your time.
