Thank you very much! I removed the negation and it worked fine. Thanks for the advice about cleaning up my code as well. Cheers!

I'm trying to make a simple block that just makes a pillar of itself when used. Everything is working when I run it, however problems arise when I save the world and reload it. All of the new blocks placed by the block disappear when the world is reloaded. I haven't been able to find much information on this and I'm relatively new to Minecraft modding and Java my background is in C/C++ for research and robotics. @Override public boolean onBlockActivated( World world, BlockPos pos, IBlockState state, EntityPlayer player, EnumHand hand, @Nullable ItemStack heldItem, EnumFacing side, float hitX, float hitY, float hitZ) { if (!world.isRemote){ return false; } Random rand = new Random(); IBlockState block = world.getBlockState(pos); for(int i = 0; i < 7; i++){ world.setBlockState(pos.add(0, i, 0), block); } for(int k = 0; k < 20; k++){ int x, z; x= rand.nextInt(16)-8; z= rand.nextInt(16)-8; EntityLightningBolt lightning = new EntityLightningBolt(world, pos.getX()+x, pos.getY(), pos.getZ()+z, false); world.addWeatherEffect(lightning); } return true; } I'm working by deconstructing examples but I seem to be missing something. Any advice is appreciated, thanks in advance.
