[1.8] Easy way to replace blocks?

Recommended Posts

It's called a for-loop.

 

for(x -10 to 10) {
  for(y -10 to 10) {
    for(z -10 to 10) {
      BlockPos pos = new BlockPos(x,y,z)
    }
  }
}

Pseudocode, of course.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

I got it to work with this:

 

  @Override
  public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer player)
  {
	if(!world.isRemote) {
		EntityPlayerMP entityplayermp = (EntityPlayerMP)player;
		MovingObjectPosition movingobjectposition = this.getMovingObjectPositionFromPlayer(world, entityplayermp, true);
		if (movingobjectposition != null && movingobjectposition.typeOfHit == MovingObjectType.BLOCK) {
			BlockPos blockpos = new BlockPos(movingobjectposition.getBlockPos());
			int x = blockpos.getX();
			int y = blockpos.getY();
			int z = blockpos.getZ();
			for(int i = 0; i < 10; ++i) {
				for(int j = 0; j < 10; ++j) {
					for(int k = 0; k < 10; ++k) {
						x = blockpos.getX() + i;
						y = blockpos.getY() + j;
						z = blockpos.getZ() + k;
						BlockPos pos = new BlockPos(x,y,z);
						world.destroyBlock(pos, true);
						System.out.println(blockpos);
						}
					}
				}
			}
		}
	return itemStack;
}

 

Next step is to destroy blocks relative to where the player is facing. Thanks :)

It's called a for-loop.

 

By the way, BlockPos now provides a cool function called getAllInBox() which returns an Iterable with all the BlockPos within a 3-D region.  You'd still use a for loop to go through it, but coding-wise it is a bit cleaner to use an iterator for the looping as you don't need to nest the loops.

I had no idea, that's awesome.
