[1.8]Item isn't consumed even with markDirty()

[blfngl 0]

Title explains it, but when a key is pressed it sets this method in motion. The method goes through and the itemstack visually decreases, but when you right click or open the inventory the itemstack is reset back to what it was previously.

 

 

@Override
public void onUpdate(ItemStack itemstack, World world, Entity entity, int metadata, boolean bool)
{
currentShot++;
currentReload++;

if (entity instanceof EntityPlayer)
{
	EntityPlayer player = (EntityPlayer) entity;
	FalloutPlayer props = FalloutPlayer.get(player);

	if (clipCount < clipSize && props.getReloadingState() == 1 && player.inventory.hasItem(ammoType))
	{
		player.playSound(reloadSound, 1.0F, 1);

		for (int i = 0; i < clipSize; i++)
		{
			if (player.inventory.hasItem(ammoType) && clipCount < clipSize)
			{
				player.inventory.consumeInventoryItem(ammoType);
				player.inventory.markDirty();
				player.inventoryContainer.detectAndSendChanges();
				clipCount++;
			}
		}

		currentReload = 0;
		props.setReloadingState(0);
	}
}
}

All these fields (currentShot, currentReload, etc.) look very suspicious. You cannot store things like that in the Item class, there is only one instance for all ItemStacks of that Item. So those values are shared across all of them.

 

Moreover you should do any inventory manipulation on the server only (world.isRemote is false).

Yeah, I'm aware that values like that are applied on a global scale. I've been using NBT tags in other versions, but they don't always seem to work, so while I'm figuring that out I'm using item values.

On another note, in the past I've used !world.isRemote checks, but the method doesn't fire. Here's an example of what I used to have:

public void onUpdate(ItemStack itemstack, World world, Entity entity, int metadata, boolean bool)
{
	if (itemstack.getTagCompound() == null)
	{
		itemstack.setTagCompound(new NBTTagCompound()); // = new NBTTagCompound();
		itemstack.getTagCompound().setInteger("clipCount", 0);
		itemstack.getTagCompound().setInteger("currentReloadTime", 0);
		itemstack.getTagCompound().setInteger("currentShotTime", 0);
	}

	if (itemstack.getTagCompound() != null)
	{
		//itemstack.getTagCompound().setInteger("currentShotTime", itemstack.getTagCompound().getInteger("currentShotTime") + 1);
		//itemstack.getTagCompound().setInteger("currentReloadTime", itemstack.getTagCompound().getInteger("currentReloadTime") + 1);

		currentShot++;
		currentReload++;

		if (entity instanceof EntityPlayer)
		{
			EntityPlayer player = (EntityPlayer) entity;
			FalloutPlayer props = FalloutPlayer.get(player);

			//if (clipCount < clipSize && Fallout.isReloading && player.inventory.hasItem(ammoType))
			if (clipCount < clipSize && props.getReloadingState() == 1 && player.inventory.hasItem(ammoType))
			{
				player.playSound(reloadSound, 1.0F, 1);

				for (int i = 0; i < clipSize; i++)
				{
					if (player.inventory.hasItem(ammoType) && clipCount < clipSize)
					{
						if (!world.isRemote)
						{
							player.inventory.consumeInventoryItem(ammoType);
							player.inventory.markDirty();
							player.inventoryContainer.detectAndSendChanges();
							clipCount++;
							//int currentClip = itemstack.getTagCompound().getInteger("clipCount");
							//itemstack.getTagCompound().setInteger("clipCount", currentClip + 1);
						}
					}
				}

				//itemstack.getTagCompound().setInteger("currentReloadTime", 0);
				currentReload = 0;
				props.setReloadingState(0);
				//Fallout.isReloading = false;
			}
		}
	}
}

 

 

I've experimented by moving !world.isRemote to different places within the method, but anything below it won't be activated.

[diesieben07 7371]

Then there is something deeply wrong with your Mod... onUpdate is always called on both client and server. What happens if you just do

println(world.isRemote)

as the only thing in onUpdate?

[blfngl 0]

It's rapidly switching between true and false...is that normal?

[diesieben07 7371]

Yes. Then an if statement which just checks if (!world.isRemote) will work.

[blfngl 0]

That's what I had in the last block and is what I'm currently using:

if (!world.isRemote)
						{
							player.inventory.consumeInventoryItem(ammoType);
							player.inventory.markDirty();
							player.inventoryContainer.detectAndSendChanges();
							clipCount++;
							//int currentClip = itemstack.getTagCompound().getInteger("clipCount");
							//itemstack.getTagCompound().setInteger("clipCount", currentClip + 1);
						}

 

This is the final check, but it still won't update. As shown above, a sound plays and then the bullets will load into the weapon. On screen it shows the current clip count out of clip size, ie 4/6 loaded, and this number is never updated as well.

[diesieben07 7371]

Again, stop using the fields in your Item class.

Switched it to this:

public void onUpdate(ItemStack itemstack, World world, Entity entity, int metadata, boolean bool)
{
	if (itemstack.getTagCompound() == null)
	{
		itemstack.setTagCompound(new NBTTagCompound());
		itemstack.getTagCompound().setInteger("clipCount", 0);
		itemstack.getTagCompound().setInteger("currentReloadTime", 0);
		itemstack.getTagCompound().setInteger("currentShotTime", 0);
		System.out.println("onUpdate tag created");
	}

	if (itemstack.getTagCompound() != null)
	{
		NBTTagCompound tag = itemstack.getTagCompound();

		tag.setInteger("currentShotTime", tag.getInteger("currentShotTime") + 1);
		tag.setInteger("currentReloadTime", tag.getInteger("currentReloadTime") + 1);

		if (entity instanceof EntityPlayer)
		{
			EntityPlayer player = (EntityPlayer) entity;
			FalloutPlayer props = FalloutPlayer.get(player);

			if (tag.getInteger("clipcount") < clipSize && props.getReloadingState() == 1 && player.inventory.hasItem(ammoType))
			{
				player.playSound(reloadSound, 1.0F, 1);

				for (int i = 0; i < clipSize; i++)
				{
					if (player.inventory.hasItem(ammoType) && tag.getInteger("clipcount") < clipSize)
					{
						if (!world.isRemote)
						{
							player.inventory.consumeInventoryItem(ammoType);
							player.inventory.markDirty();
							//player.inventoryContainer.detectAndSendChanges();

							int currentClip = tag.getInteger("clipcount");
							tag.setInteger("clipCount", currentClip + 1);
						}
					}
				}

				tag.setInteger("currentReloadTime", 0);
				props.setReloadingState(0);
			}
		}
	}
}

 

 

When I don't have the worldRemote check the ammo is consumed (and stays consumed), but the tag is not updated. If the check is there all it does is play the sound.

[diesieben07 7371]

All of that code should happen serverside only.

[blfngl 0]

Kay, looks like this now:

public void onUpdate(ItemStack itemstack, World world, Entity entity, int metadata, boolean bool)
{
	if (!world.isRemote)
	{
		if (itemstack.getTagCompound() == null)
		{
			itemstack.setTagCompound(new NBTTagCompound());
			itemstack.getTagCompound().setInteger("clipCount", 0);
			itemstack.getTagCompound().setInteger("currentReloadTime", 0);
			itemstack.getTagCompound().setInteger("currentShotTime", 0);
			System.out.println("onUpdate tag created");
		}

		if (itemstack.getTagCompound() != null)
		{
			NBTTagCompound tag = itemstack.getTagCompound();

			tag.setInteger("currentShotTime", tag.getInteger("currentShotTime") + 1);
			tag.setInteger("currentReloadTime", tag.getInteger("currentReloadTime") + 1);

			if (entity instanceof EntityPlayer)
			{
				EntityPlayer player = (EntityPlayer) entity;
				FalloutPlayer props = FalloutPlayer.get(player);

				if (tag.getInteger("clipcount") < clipSize && props.getReloadingState() == 1 && player.inventory.hasItem(ammoType))
				{
					player.playSound(reloadSound, 1.0F, 1);

					for (int i = 0; i < clipSize; i++)
					{
						if (player.inventory.hasItem(ammoType) && tag.getInteger("clipcount") < clipSize)
						{
							player.inventory.consumeInventoryItem(ammoType);
							player.inventory.markDirty();
							//player.inventoryContainer.detectAndSendChanges();

							int currentClip = tag.getInteger("clipcount");
							tag.setInteger("clipCount", currentClip + 1);
						}
					}

					tag.setInteger("currentReloadTime", 0);
					props.setReloadingState(0);
				}
			}
		}
	}
}

 

 

Now nothing at all happens. There's a keybind I'm using that tells an IExtendedEntityProperties class that a player is reloading and sets a certain integer mark that. After the player is done reloading, it sets the int back to 0, but I think it's all on the client side. Would that be the reason this isn't communicating? I inserted println checks and it wont stop printing after it reached the IExtendedEntityProperties check.

[diesieben07 7371]

Ehh, yes, Obviously that would be the reason. You must send a packet when the key is pressed to tell the server that you want to reload.
