Oh - I derped so bad. I had an event that was setting it to null accidentally... Thanks for the help delpi!

I have already tried that. When I log off and back on, the item has been set to null again. Also, that saves an ITEMSTACK - I just want to save an item... Here is the code: package com.kwibble.dendri.entity.player; import com.kwibble.dendri.item.ItemDendrikBelt; import net.minecraft.entity.Entity; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.init.Blocks; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.nbt.NBTTagCompound; import net.minecraft.world.World; import net.minecraftforge.common.IExtendedEntityProperties; import com.kwibble.dendri.ModDendri; public class PlayerInformation implements IExtendedEntityProperties { public static final String IDENTIFIER = ModDendri.MODID + "_playerProperties"; private static final String IS_OVERLAY_MINIMIZED_IDENTIFIER = IDENTIFIER + "_isOverlayMinimized"; private static final String CURRENT_DENDRIK_BELT_IDENTIFIER = IDENTIFIER + "_currentDendrikbelt"; public static PlayerInformation forPlayer(Entity player) { return (PlayerInformation) player.getExtendedProperties(IDENTIFIER); } private EntityPlayer player; private ItemStack currentDendrikBelt; private boolean isOverlayMinimized; public PlayerInformation(EntityPlayer player) { this.player = player; } @Override public void init(Entity entity, World world) { } @Override public void saveNBTData(NBTTagCompound compound) { System.out.println("Saving NBT Data:"); compound.setBoolean(IS_OVERLAY_MINIMIZED_IDENTIFIER, this.isOverlayMinimized); System.out.println("Saved isOverlayMinimized with value of: " + this.isOverlayMinimized); if (this.currentDendrikBelt != null) { compound.setTag(CURRENT_DENDRIK_BELT_IDENTIFIER, this.currentDendrikBelt.writeToNBT(new NBTTagCompound())); System.out.println("Saved currentDendrikbelt with value of: " + this.currentDendrikBelt); } System.out.println("NBT Data Saved"); } @Override public void loadNBTData(NBTTagCompound compound) { System.out.println("Loading NBT Data:"); this.isOverlayMinimized = compound.getBoolean(IS_OVERLAY_MINIMIZED_IDENTIFIER); System.out.println("Loaded isOverlayMinimized with value of: " + this.isOverlayMinimized); this.currentDendrikBelt = ItemStack.loadItemStackFromNBT(compound.getCompoundTag(CURRENT_DENDRIK_BELT_IDENTIFIER)); System.out.println("Loaded currentDendrikBelt with value of: " + this.currentDendrikBelt); System.out.println("Loaded NBT Data"); } public void setCurrentDendrikBelt(Item belt) { if (belt instanceof ItemDendrikBelt) this.currentDendrikBelt = new ItemStack(belt); else System.out.println("A Dendrik Belt was not passed in"); } public Item getCurrentDendrikBelt() { return this.currentDendrikBelt != null ? this.currentDendrikBelt.getItem() : new ItemStack(Blocks.stone).getItem(); } public void setIsOverlayMinimized(boolean isOverlayMinimized) { this.isOverlayMinimized = isOverlayMinimized; } public boolean getIsOverlayMinimized() { return this.isOverlayMinimized; } } Thanks delpi

I have an Item in an IExtendedEntityProperties that I want to save into the NBT.... how would I go about doing this? I have absolutely no clue what so ever on how to do this, so all help is appreciated.

You could always use GL11.glDisable(GL11.GL_LIGHTING); before your drawing and GL11.glEnable(GL11.GL_LIGHTING); after. This would help you figure out if your textures are there or not.

@diesieben07 I have already sorted this out with him. I have helped him find his errors A) he wasn't registering his items via GameRegistry.registerItem() and he was getting weird crashes because of it. And other things besides. But its all good now

Bind one texture at a time as you need it... Not all at once. (that is what I got from that) Also, it's: new ResourceLocation("modid", "textures/blocks/block_front.png") That could well solve your problem.

Like I said... bind textures via minecraftInstance.getTextureManager().bindTexture(resourcelocation);

Wow... Thanks. I feel a little... low on brain cells after that

Oh, okay. Still a little confused, but good to go! Also... Noob gradle man is me. I know you can update forge without destroying ones workspace, but how do you do it???

Oops, forgot to supply my IMessage + IMessageHandler and registry... Here it is: IMessage/IMessageHandler: package com.kwibble.dendri.network.message; import com.kwibble.dendri.entity.player.PlayerInformation; import cpw.mods.fml.common.network.simpleimpl.IMessage; import cpw.mods.fml.common.network.simpleimpl.IMessageHandler; import cpw.mods.fml.common.network.simpleimpl.MessageContext; import io.netty.buffer.ByteBuf; /** * Created by 102676 on 18/06/14. */ public class MessagePlayerInfo implements IMessage { private boolean isOverlayMinimized; public MessagePlayerInfo(){} public MessagePlayerInfo(PlayerInformation playerinfo) { this.isOverlayMinimized = playerinfo.getIsOverlayMinimized(); } @Override public void fromBytes(ByteBuf buf) { this.isOverlayMinimized = buf.readBoolean(); } @Override public void toBytes(ByteBuf buf) { buf.writeBoolean(this.isOverlayMinimized); } public static class Handler implements IMessageHandler<MessagePlayerInfo, IMessage> { @Override public IMessage onMessage(MessagePlayerInfo message, MessageContext ctx) { System.out.println("Test recieve: " + message.isOverlayMinimized); return null; } } } DendriNetwork: package com.kwibble.dendri.network; import com.kwibble.dendri.ModDendri; import com.kwibble.dendri.network.message.MessagePlayerInfo; import cpw.mods.fml.common.network.NetworkRegistry; import cpw.mods.fml.common.network.simpleimpl.SimpleNetworkWrapper; import cpw.mods.fml.relauncher.Side; /** * Created by 102676 on 19/06/14. */ public class DendriNetwork { private static final String CHANNEL_NAME = ModDendri.MODID; public static SimpleNetworkWrapper dendriNetwork; public static void registerNetwork() { dendriNetwork = NetworkRegistry.INSTANCE.newSimpleChannel(CHANNEL_NAME); dendriNetwork.registerMessage(MessagePlayerInfo.class, MessagePlayerInfo.class, 0, Side.CLIENT); } } And in my main mod, in the preInit method, I call DendriNetwork.registerNetwork()

Also... I am trying to register a testing packet, and it isn't working and throwing this error: java.lang.IllegalStateException: cannot determine the type of the type parameter 'REQ': class

Okay, thanks. The "anti-hacking" packet makes sense, but I am not sure how to go about it. Could you steer me in the right direction please?

That makes sense. But what if I have say a GUI that updates something in the IExtendedEntityPrroperties? Do I have to create a nee IMessage to sync the data to the server?

So I have solved question one. I discovered that using ByteBufUtils you can send an ItemStack. That was easier than I thought it would be. Question 2 still stands though.

1. Is it possible to send an item via a message (I am following the SimpleNetworkWrapper tutorial by diesieben07)? If so, how would one do it? 2. If I want to have a bit of information (not a bit bit, just a small amount of information) that I want to be synced, how do I go about this? I have an IExtendedEntityProperties that has stuff I want synced for me, but I am not entirely sure how to go about it. For reference, here is my PlayerInformation class: package com.kwibble.dendri.entity.player; import com.kwibble.dendri.item.ItemDendrikBelt; import net.minecraft.entity.Entity; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.ItemStack; import net.minecraft.nbt.NBTTagCompound; import net.minecraft.util.MathHelper; import net.minecraft.world.World; import net.minecraftforge.common.IExtendedEntityProperties; import com.kwibble.dendri.ModDendri; import com.kwibble.dendri.item.ItemDendri; public class PlayerInformation implements IExtendedEntityProperties { public static final String IDENTIFIER = ModDendri.MODID + "_playerProperties"; private static final String IS_OVERLAY_MINIMIZED_IDENTIFIER = IDENTIFIER + "_isOverlayMinimized"; public static PlayerInformation forPlayer(Entity player) { return (PlayerInformation) player.getExtendedProperties(IDENTIFIER); } private EntityPlayer player; private ItemDendrikBelt currentDendrikBelt; private boolean isOverlayMinimized; public PlayerInformation(EntityPlayer player) { this.player = player; } @Override public void init(Entity entity, World world) { } @Override public void saveNBTData(NBTTagCompound compound) { System.out.println("Saving NBT Data:"); compound.setBoolean(IS_OVERLAY_MINIMIZED_IDENTIFIER, this.isOverlayMinimized); System.out.println("Saved isOverlayMinimized with value of: " + this.isOverlayMinimized); System.out.println("NBT Data Saved"); } @Override public void loadNBTData(NBTTagCompound compound) { System.out.println("Loading NBT Data:"); this.isOverlayMinimized = compound.getBoolean(IS_OVERLAY_MINIMIZED_IDENTIFIER); System.out.println("Loaded isOverlayMinimized with value of: " + this.isOverlayMinimized); System.out.println("Loaded NBT Data"); } public void setCurrentDendrikBelt(ItemDendri belt) { if (belt instanceof ItemDendrikBelt) this.currentDendrikBelt = (ItemDendrikBelt) belt; else System.out.println("A Dendrik Belt was not passed in"); } public ItemDendrikBelt getCurrentDendrikBelt() { return this.currentDendrikBelt; } public void setIsOverlayMinimized(boolean isOverlayMinimized) { this.isOverlayMinimized = isOverlayMinimized; } public boolean getIsOverlayMinimized() { return this.isOverlayMinimized; } } [EDIT] Now I know that I need an IMessage, and I have that. It's more a question of do I need a packet for sending from the server to the client, and another from the client to the server? Or can it be done in one IMessage/ImessageHandler.

Forge isn't really an API per-se. The only real API stuff is the Registries (GameRegistry, NetworkRegistry etc.), and the Event Buses (MinecraftForge.EVENT_BUS, FMLCommonHandler.instance().bus() [i think]). Aside from that... Javadocs mainly, that's what we use. And just guessing by what things are named... But that can lead to interesting results sometimes

Well... Funny you should ask that. There isn't really that much documentation sorry. There is some great Forge documentation, but then again... You'll have to keep searching for good in-depth stuff.

Try looking up ScratchForFun on youtube. He has some great tutorials for 1.7.x (as well as a very cool accent). Then there is also TheGrovesyProject101, another very good *tutorialer*

uhh... What? You set your showTail variable to false, then call setShowTail(true). What is this supposed to achieve? You managed to make it sound redundant.

Please, if you are posting code, put it inside code tags [ code ] and [/ code ] (NOTE: do not use spaces) example: public void doNothing() { // What? You were expecting something? } Also, please use the spoiler [ spoiler ] and [/ spoiler ] (NOTE: also with no spaces) for your crash reports. It just makes things A LOT easier to read.

Oh most definitely call super. If you don't call super, the entity's position and rotation and those sorts of things aren't saved

They are very simply called, and they readFromNBT and writeToNBT with an NBTTagCompound as the parameter

A) umm... Why are you using a method called getMaxHealth() when it is clearly acting as the current health?

Try using the other read/write nbt methods. Those two you are using are documented as being used to load *sub* classes of the entity.

Reflection could also be used (I think). Don't ask me how, but you could. It all depends on how often you are wanting to access that one variable.
