Because WorldEvent.Load fires when the world is being loaded (which happens every time you get into the game). I don't need to add items when the world loads, I need to add them when the player first joins a new world.

I figured out how to give player certain items when they respawn after death. The problem I'm having is when I generate a new world - the inventory is empty. Is that a different kind of event I have to handle?

diesieben07, You were right. I'm sending packets to the server that tells it to increase or decrease and it all works Thanks a lot for the help!

The weird thing is EVERYTHING works correctly, except the fact that anytime i want to save to NBTs, the value of any variable is zero. The loading from NBTs works perfectly. If I assign the value of trashAmount to be lets say 10 INSIDE the NBT Save, then the value will save correctly. However when I dont assign it and just try to pull it, the int is always zero. No idea why this is happening and supposedly it works in the tutorial. Anyhow, Yes, I need this to persist through players death. This will be a singleplayer mod ONLY if that makes any difference. TLHPoE, if you could link me to a tutorial or give me a general idea how players NBT works, I'd be grateful. Thanks guys!

The values are changed by the method setTrash and that is also when i sync it. The only other place with sync is in my event handler. package org.theya.sustain.gui; import net.minecraft.entity.player.EntityPlayer; import net.minecraftforge.event.ForgeSubscribe; import net.minecraftforge.event.entity.EntityJoinWorldEvent; import net.minecraftforge.event.entity.EntityEvent.EntityConstructing; public class PollutionHandler { @ForgeSubscribe public void onEntityConstructing(EntityConstructing event) { if(event.entity instanceof EntityPlayer && PollutionBarData.get((EntityPlayer)event.entity) == null) { PollutionBarData.register((EntityPlayer)event.entity); } if(event.entity instanceof EntityPlayer && event.entity.getExtendedProperties(PollutionBarData.POLLUTION_DATA_NAME) == null) { event.entity.registerExtendedProperties(PollutionBarData.POLLUTION_DATA_NAME, new PollutionBarData((EntityPlayer)event.entity)); } } @ForgeSubscribe public void onEntityJoinWorld(EntityJoinWorldEvent event) { if(!event.entity.worldObj.isRemote && event.entity instanceof EntityPlayer) { PollutionBarData.get((EntityPlayer)event.entity).sync(); } } } I call set Trash in my CustomGui class and I do it like this: PollutionBarData props = PollutionBarData.get((EntityPlayer)this.mc.getNetHandler().getPlayer()); props.setTrash(props.getTrash() + 1);

I've been figuring out the IExtendedEntityProperties and have a problem with them. I found coolAlias tutorial on that stuff and pretty much followed it (http://www.minecraftforum.net/topic/1952901-172164-eventhandler-and-iextendedentityproperties/). This is pretty much what my class looks like: package org.theya.sustain.gui; import java.io.ByteArrayOutputStream; import java.io.DataOutputStream; import java.io.IOException; import net.minecraft.entity.Entity;

if(!player.worldObj.isRemote) { EntityPlayerMP player1 = (EntityPlayerMP) player; PacketDispatcher.sendPacketToPlayer(packet, (Player)player1); System.out.println("packet sent to player: " + this.trashAmount); } } @Override public void init(Entity entity, World world) { } public void setTrash(int amount) { this.trashAmount = amount; this.sync(); } public int getTrash() { return trashAmount; } } And here is the output: 2014-03-29 12:54:59 [iNFO] [ForgeModLoader] Loading dimension 0 (New World) (net.minecraft.server.integrated.IntegratedServer@68689d26) 2014-03-29 12:54:59 [iNFO] [ForgeModLoader] Loading dimension 1 (New World) (net.minecraft.server.integrated.IntegratedServer@68689d26) 2014-03-29 12:54:59 [iNFO] [ForgeModLoader] Loading dimension -1 (New World) (net.minecraft.server.integrated.IntegratedServer@68689d26) 2014-03-29 12:54:59 [iNFO] [Minecraft-Server] Preparing start region for level 0 2014-03-29 12:55:00 [iNFO] [sTDOUT] [NBT-READ] Trash amount: 9 2014-03-29 12:55:00 [iNFO] [sTDOUT] loading single player 2014-03-29 12:55:00 [iNFO] [Minecraft-Server] Player106[/127.0.0.1:0] logged in with entity id 282 at (168.69339168635545, 64.0, -100.73887055738551) 2014-03-29 12:55:00 [iNFO] [Minecraft-Server] Player106 joined the game 2014-03-29 12:55:00 [iNFO] [sTDOUT] [sYNC] Writing amount: 9 2014-03-29 12:55:00 [iNFO] [sTDOUT] packet sent to player: 9 2014-03-29 12:55:00 [iNFO] [sTDOUT] Setting up custom skins 2014-03-29 12:55:00 [iNFO] [sTDOUT] [sYNC] Writing amount: 9 2014-03-29 12:55:00 [iNFO] [sTDOUT] [PACKET] Trash from packet: 9 2014-03-29 12:55:00 [iNFO] [Minecraft-Client] [CHAT] Welcome Player106 to this world 2014-03-29 12:55:02 [iNFO] [sTDOUT] [sYNC] Writing amount: 10 2014-03-29 12:55:02 [iNFO] [sTDOUT] XYZ: 158, 63, -135 2014-03-29 12:55:17 [iNFO] [Minecraft-Server] Saving and pausing game... 2014-03-29 12:55:17 [iNFO] [sTDOUT] [NBT-SAVE] Trash amount saved: 9 2014-03-29 12:55:17 [iNFO] [sTDOUT] [NBT-SAVE][PROPS] Trash amount: 9 2014-03-29 12:55:17 [iNFO] [sTDOUT] [NBT-SAVE] Trash amount saved: 9 2014-03-29 12:55:17 [iNFO] [sTDOUT] [NBT-SAVE][PROPS] Trash amount: 9 2014-03-29 12:55:17 [iNFO] [Minecraft-Server] Saving chunks for level 'New World'/Overworld 2014-03-29 12:55:17 [iNFO] [Minecraft-Server] Saving chunks for level 'New World'/Nether 2014-03-29 12:55:17 [iNFO] [Minecraft-Server] Saving chunks for level 'New World'/The End 2014-03-29 12:55:23 [iNFO] [Minecraft-Server] Stopping server 2014-03-29 12:55:23 [iNFO] [Minecraft-Server] Saving players 2014-03-29 12:55:23 [iNFO] [sTDOUT] [NBT-SAVE] Trash amount saved: 9 2014-03-29 12:55:23 [iNFO] [sTDOUT] [NBT-SAVE][PROPS] Trash amount: 9 2014-03-29 12:55:23 [iNFO] [sTDOUT] [NBT-SAVE] Trash amount saved: 9 2014-03-29 12:55:23 [iNFO] [sTDOUT] [NBT-SAVE][PROPS] Trash amount: 9 2014-03-29 12:55:23 [iNFO] [Minecraft-Server] Player106 left the game 2014-03-29 12:55:23 [iNFO] [sTDOUT] [NBT-SAVE] Trash amount saved: 9 2014-03-29 12:55:23 [iNFO] [sTDOUT] [NBT-SAVE][PROPS] Trash amount: 9 2014-03-29 12:55:23 [iNFO] [sTDOUT] [NBT-SAVE] Trash amount saved: 9 2014-03-29 12:55:23 [iNFO] [sTDOUT] [NBT-SAVE][PROPS] Trash amount: 9 2014-03-29 12:55:23 [iNFO] [Minecraft-Server] Saving worlds 2014-03-29 12:55:23 [iNFO] [Minecraft-Server] Saving chunks for level 'New World'/Overworld 2014-03-29 12:55:23 [iNFO] [Minecraft-Server] Saving chunks for level 'New World'/Nether 2014-03-29 12:55:23 [iNFO] [Minecraft-Server] Saving chunks for level 'New World'/The End 2014-03-29 12:55:23 [iNFO] [ForgeModLoader] Unloading dimension 0 2014-03-29 12:55:23 [iNFO] [ForgeModLoader] Unloading dimension -1 2014-03-29 12:55:23 [iNFO] [ForgeModLoader] Unloading dimension 1 2014-03-29 12:55:23 [iNFO] [Minecraft-Client] Stopping! 2014-03-29 12:55:23 [iNFO] [sTDOUT] 2014-03-29 12:55:23 [iNFO] [sTDOUT] SoundSystem shutting down... 2014-03-29 12:55:24 [iNFO] [sTDOUT] Author: Paul Lamb, www.paulscode.com 2014-03-29 12:55:24 [iNFO] [sTDOUT] Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release The problem that I have is NBT load happens correctly and the trash amount is 9. Then it changes to 10 and the sync function tells that its 10. However, when I press ESC and the NBTs are saving, it tells me it saved it as 9. I've been trying to figure out what am I doing wrong here...

So i create a dummy entity and use it to read and write NBTs?

I have a custom gui bar that renders on the screen at the same time xp bar does. Its a little mana indicator. The problem is I have to save it somehow when the player exits. My question is, do I need TileEntity to save NBTs? If yes, can you please point me to an example? Maybe there is a better way to do it? Thanks for the help!

I'm beating myself with a stick right now. Turns out I had 2 of them placed and for some reason didn't realize that could be the issue. Thanks a lot for help and sorry for the trouble!

That is what I thought, so I decided to do this: if(!this.worldObj.isRemote) { System.out.println(this.worldObj.getBlockId(xCoord + 1, yCoord, zCoord)); } Unfortunately same thing.

I'm trying to get a block that is next to my custom furnace. In TileEntityBrickFurnace class I simply wrote: System.out.println(this.worldObj.getBlockId(xCoord + 1, yCoord, zCoord)); The results look like this: 2014-03-08 13:02:00 [iNFO] [sTDOUT] 9 2014-03-08 13:02:00 [iNFO] [sTDOUT] 0 2014-03-08 13:02:00 [iNFO] [sTDOUT] 9 2014-03-08 13:02:00 [iNFO] [sTDOUT] 0 2014-03-08 13:02:00 [iNFO] [sTDOUT] 9 2014-03-08 13:02:00 [iNFO] [sTDOUT] 0 2014-03-08 13:02:00 [iNFO] [sTDOUT] 9 2014-03-08 13:02:00 [iNFO] [sTDOUT] 0 2014-03-08 13:02:00 [iNFO] [sTDOUT] 9 2014-03-08 13:02:00 [iNFO] [sTDOUT] 0 2014-03-08 13:02:00 [iNFO] [sTDOUT] 9 2014-03-08 13:02:00 [iNFO] [sTDOUT] 0 2014-03-08 13:02:00 [iNFO] [sTDOUT] 9 2014-03-08 13:02:00 [iNFO] [sTDOUT] 0 2014-03-08 13:02:00 [iNFO] [sTDOUT] 9 2014-03-08 13:02:00 [iNFO] [sTDOUT] 0 Instead of just telling me its 9 or 0, it alternates for some reason.

Of course it can! How did I not see this... This seems to fix my issue, thanks a lot for help!

This is for 1.6.4, but most of this stuff should be easy to covert to 1.7.2
