Hi, im making a gold coin manager for minecraft 1.6.2 you can add and remove gold. It saves fine for singleplayer and for the player hosting the world over lan, but it doesnt save gold for other players over lan and they have to start again!

 

My question:

How can i save the int gold for a player over lan?

 

Details:

Im using NBTTagCompound to save and load.

 

My GoldHandler class:

My PlayerHandler class:

1: i would use IExtendedProperty for that (and EntityConstructingEvent)

2:

 

  Quote
private static int currGold;

do you know what static means ??? because that would mean that its the SAME amount of gold for everyone

 

and btw theres no difference between LAN and a real server

Hi, first of all thanks for replying.

 

I do know what static means and when more that 1 player are on the world they have different gold values so that isnt a problem.

 

Can u pls explain a bit more about the iextendedproperty?

 

Thanks

i can 100% guarantee you that it doesnt work like you want it to

but since you're confident i wont talk about it

 

 

for IExtendedProperty, make a class that implements it and attach it to an entity. this way you will be noticed when an entity is saved to the NBT and you can add your gold there

 

 

ps: [lmgtfy]how to use hashmap in java[/lmgtfy], trust me it will help

am i the only one who actually traced the code and foudn out that the currGold should NOT be static

 

 

1 everythign in thsi class is static except the constructor (but it cant sooo ... )

 

2:

public static void addGold(EntityPlayer player, int gold) {
      int index;
      GoldHandler instance;
      for(int i=0; i<PlayerHandler.names.size(); i++) {
         if(PlayerHandler.names.get(i).equalsIgnoreCase(player.username)) {
            index = i;
            instance = PlayerHandler.gh.get(i);
            break;
         }
      }
      currGold += gold;
      NBTTagCompound tag = player.getEntityData();
      tag.setInteger("player" + player.username + "Gold", currGold);
   }

what exactly is the variable "instance" suppose to do ? same for "index"

this code is the same as:

public static void addGold(EntityPlayer player, int gold) {
      currGold += gold;
      NBTTagCompound tag = player.getEntityData();
      tag.setInteger("player" + player.username + "Gold", currGold);
   }

 

 

same here ? instance and index are never used (actually most IDE would be whining about this)

public static void removeGold(EntityPlayer player, int gold) {
      int index;
      GoldHandler instance;
      for(int i=0; i<PlayerHandler.names.size(); i++) {
         if(PlayerHandler.names.get(i).equalsIgnoreCase(player.username)) {
            index = i;
            instance = PlayerHandler.gh.get(i);
            break;
         }
      }
      currGold -= gold;
      NBTTagCompound tag = player.getEntityData();
      tag.setInteger("player" + player.username + "Gold", currGold);
   }

is the same as:

public static void removeGold(EntityPlayer player, int gold) {
      currGold -= gold;
      NBTTagCompound tag = player.getEntityData();
      tag.setInteger("player" + player.username + "Gold", currGold);
   }

 

if you want to see how it doesnt work

 

do this:

take 2 player, set their gold to 50 each

add 25 gold to one player

remove 10 gold to the OTHER player

    • wait, i just did that. why didn't it work? also it's the same. help me!!!!
    • Culprit has been located! It was Tough As Nails + (plus) which was among one of the mods *added* before re-entering, in an attempt to improve compatibility. It, for some reason or another, did not want to work!
    • "You can either try to load it with only the vanilla data pack ("safe mode"), or go back to the title screen and fix it manually." Hello! I encountered this error just now while attempting to re-enter my world for the first time. Notably, no mods were removed before encountering this error and, while being able to find this error elsewhere on the internet, in my scenario it is seemingly caused by a specific mod, of which I cannot isolate. Things I have tried: - Enter "Safe Mode" (fails) - Remove datapacks (no change) - Reverted to old save data (no change) Here is the server log: https://mclo.gs/9vJQEfN I use Modrinth mod loader so please let me know how to share my mod list, and if it is needed.
    • So, i'm hosting (or attempting to host) a port-forwarded modded server for 1.12.2. There's quite a few mods in this pack, but they all run and have no compatibility issues (besides something causing the game to crash if you go fullscreen, a problem ive given up trying to identify or fix). It can run on 6gb of ram or less, and works fine in singleplayer. All of my friends that want to join have the exact same mod/config/game setup as I do (I personally helped them set everything up). Just to be safe, we've all allocated 12 gigabytes of RAM to the installation, and I've also allocated 12GB to the server itself. I am able to join with no issue and it runs fine. However, when they try to join, it gets stuck in the 'logging in' screen before their game becomes unresponsive. When they close it, it gives them the exit code 805306369, which usually means not enough RAM, but this cant be the case. On my screen, in the server, it shows them joining, and then disconnecting, so I dont think its a port-forwarding issue. They can all run it just fine in singleplayer as well. The annoying bit about this particular issue is that it generates no crash log. Does anyone have any suggestions? Thanks! Here is my debug log, and his, starting from the same place.
