Posted October 29, 20169 yr Hello! I've recently tried to get back to work on my mod that I've not worked on in months. Where I left off, I was working on a system to transfer steam through pipes to power my machinery. What I remember from back then was that some change in my code broke the system and now occasionally the game throws this crash: [18:35:51] [server thread/ERROR]: This crash report has been saved to: C:\Users\Nemo\Desktop\Programming\Gears N' Clouds 1.8\eclipse\.\crash-reports\crash-2016-10-29_18.35.51-server.txt [18:35:51] [server thread/INFO]: Stopping server [18:35:51] [server thread/INFO]: Saving players [18:35:51] [Client thread/INFO] [sTDOUT]: [net.minecraft.init.Bootstrap:printToSYSOUT:663]: ---- Minecraft Crash Report ---- // You should try our sister game, Minceraft!

I've decoded this and found the source of the problem which is in this if statement (I will warn you, this if statement is incredibly long and will therefore look strange in this post. If you copy it and post it in a notepad document, it will look normal): if((worldObj.getBlockState(new BlockPos(pos.getX() + 1, pos.getY(), pos.getZ())).getBlock() == worldObj.getBlockState(pos).getBlock()) &&((worldObj.getBlockState(pos).getBlock() == worldObj.getBlockState(new BlockPos(pos.getX() - 1, pos.getY(), pos.getZ())).getBlock() && (worldObj.getTileEntity(pos).getTileData().getString("liquid") == worldObj.getTileEntity(new BlockPos(pos.getX() - 1, pos.getY(), pos.getZ())).getTileData().getString("liquid") || worldObj.getTileEntity(new BlockPos(pos.getX() - 1, pos.getY(), pos.getZ())).getTileData().getString("liquid") == "nothing") && worldObj.getTileEntity(new BlockPos(pos.getX() + 1, pos.getY(), pos.getZ())).getTileData().getInteger("fillLevel") <= worldObj.getTileEntity(new BlockPos(pos.getX() - 1, pos.getY(), pos.getZ())).getTileData().getInteger("fillLevel")) ^ (worldObj.getBlockState(pos).getBlock() != worldObj.getBlockState(new BlockPos(pos.getX() - 1, pos.getY(), pos.getZ())).getBlock() || worldObj.getTileEntity(new BlockPos(pos.getX() - 1, pos.getY(), pos.getZ())).getTileData().getString("liquid") != worldObj.getTileEntity(pos).getTileData().getString("liquid"))) &&((worldObj.getBlockState(pos).getBlock() == worldObj.getBlockState(new BlockPos(pos.getX(), pos.getY(), pos.getZ() + 1)).getBlock() && (worldObj.getTileEntity(pos).getTileData().getString("liquid") == worldObj.getTileEntity(new BlockPos(pos.getX(), pos.getY(), pos.getZ() + 1)).getTileData().getString("liquid") || worldObj.getTileEntity(new BlockPos(pos.getX(), pos.getY(), pos.getZ() + 1)).getTileData().getString("liquid") == "nothing") && worldObj.getTileEntity(new BlockPos(pos.getX() + 1, pos.getY(), pos.getZ())).getTileData().getInteger("fillLevel") <= worldObj.getTileEntity(new BlockPos(pos.getX(), pos.getY(), pos.getZ() + 1)).getTileData().getInteger("fillLevel")) ^ (worldObj.getBlockState(pos).getBlock() != worldObj.getBlockState(new BlockPos(pos.getX(), pos.getY(), pos.getZ() + 1)).getBlock() || worldObj.getTileEntity(new BlockPos(pos.getX(), pos.getY(), pos.getZ() + 1)).getTileData().getString("liquid") != worldObj.getTileEntity(pos).getTileData().getString("liquid"))) &&((worldObj.getBlockState(pos).getBlock() == worldObj.getBlockState(new BlockPos(pos.getX(), pos.getY(), pos.getZ() - 1)).getBlock() && (worldObj.getTileEntity(pos).getTileData().getString("liquid") == worldObj.getTileEntity(new BlockPos(pos.getX(), pos.getY(), pos.getZ() - 1)).getTileData().getString("liquid") || worldObj.getTileEntity(new BlockPos(pos.getX(), pos.getY(), pos.getZ() - 1)).getTileData().getString("liquid") == "nothing") && worldObj.getTileEntity(new BlockPos(pos.getX() + 1, pos.getY(), pos.getZ())).getTileData().getInteger("fillLevel") <= worldObj.getTileEntity(new BlockPos(pos.getX(), pos.getY(), pos.getZ() - 1)).getTileData().getInteger("fillLevel")) ^ (worldObj.getBlockState(pos).getBlock() != worldObj.getBlockState(new BlockPos(pos.getX(), pos.getY(), pos.getZ() - 1)).getBlock() || worldObj.getTileEntity(new BlockPos(pos.getX(), pos.getY(), pos.getZ() - 1)).getTileData().getString("liquid") != worldObj.getTileEntity(pos).getTileData().getString("liquid")))) { fillLevel = worldObj.getTileEntity(pos).getTileData().getInteger("fillLevel"); NBTTagCompound tag = worldObj.getTileEntity(new BlockPos(pos.getX() + 1, pos.getY(), pos.getZ())).getTileData(); int temp = tag.getInteger("fillLevel"); tag.setInteger("fillLevel", ((fillLevel - temp) / 2) + temp); tag.setString("liquid", "Steam"); fillLevel = fillLevel - (fillLevel - temp) / 2; worldObj.getTileEntity(pos).getTileData().setInteger("fillLevel", fillLevel); } The issue in the statement being this line of code: worldObj.getTileEntity(pos).getTileData().getString("liquid") == worldObj.getTileEntity(new BlockPos(pos.getX() - 1, pos.getY(), pos.getZ())).getTileData().getString("liquid") My theory is that because if the block it is checking for is not a tile entity, it doesn't know what to do and therefore crashes. I don't know how to solve this issue though and would appreciate any help I could get! If any more code is required, just ask me and I'll add it to this main post! Thanks in advance!
October 29, 20169 yr Solution: Not being a fucking idiot. Step 1: get the TE Step 2: check for null Step 3: do your stuff And bonus step: Not doing your stuff by manipulating NBT data. Use Capabilities. 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. Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked. DO NOT PM ME WITH PROBLEMS. No help will be given.
October 29, 20169 yr Also, if you want to change a BlockPos over 1 block, use BlockPos#[direction]() . Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support. 1.12 -> 1.13 primer by williewillus. 1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support. http://www.howoldisminecraft1710.today/
