[1.12.2]Entity NBT not saving

I have two spell entities - one is a shield, the other is a disarming bullet.

NBT is not being saved. The caster is not saved for either and the size is not saved for the shield.

I know because all my shields are tiny on the client but react in a five block range, and neither recognize the caster.

Example: saying Expelliarmus while holding a wand shoots the spell, but not only does it launch the target, it launches you, because the client does not know who cast it, and therefore - who not to hit.

 

Shield Charm 

@Override
	public void readFromNBT(NBTTagCompound nbt) {
		super.readFromNBT(nbt);
		this.size = nbt.getFloat("size");
		setSize(size, size);
		NBTTagList list = (NBTTagList) nbt.getTag("casters");
		List<Entity> entities = world.getEntitiesWithinAABB(Entity.class, this.getEntityBoundingBox());
		for (NBTBase n : list) {
			String uuid = n.toString();
			for (Entity e : entities) {
				if (e.getPersistentID().toString() == uuid) caster.add(e);
			}
		}
	}
	@Override
	public NBTTagCompound writeToNBT(NBTTagCompound nbt) {
		super.writeToNBT(nbt);
		nbt.setFloat("size", size);
		NBTTagList list = new NBTTagList();
		for (Entity e : caster) {
			list.appendTag(new NBTTagString(e.getPersistentID().toString()));
		}
		nbt.setTag("casters", list);
		return nbt;
	}

And the Disarming spell extends EntityThrowale so it should save the thrower flag.

 

In PreInit 

EntityRegistry.registerModEntity(new ResourceLocation(WizardryMod.MODID, "entitySpellShield"), EntityShieldCharm.class, "shieldSpell", 998, this, 100, 1, false);
		EntityRegistry.registerModEntity(new ResourceLocation(WizardryMod.MODID, "entityDisarmShield"), EntityDisarmSpell.class, "disarmSpell", 999, this, 100, 6, true);

Well a few things. First of all you shouldn't have to guess whether the code is running -- you should either add console statements in the methods or you should set breakpoints and run the code in debug mode. For something like this I would use console statements because then you'd get a good sense of when it might be saving or not, and you can also print out the values of key fields at that point in the execution. That way you can figure out if the code simply isn't running, or if it running but the values loaded don't match for some reason. 

 

Secondly, it looks like you're saying that the NBT code is in the shield charm, but your title says "entity nbt". Which is it? Is that data for the shield item or for the entity? If it is for the shield item, at what point do you expect it to be saved?

 

Thirdly, most of these sorts of problems are confusion about how to sync the client and the server. There are vanilla processes to sync the vanilla stuff, and some ability to have extended data communicated, but you often have to make sure either by initiating packets (through share tag methods, send packet methods, or mark dirty methods depending on the thing you're trying to sync), or even going as far as sending custom packets if necessary.

 

Also, I've found there is some tricks about NBT used together with item capabilities. Not clear if you're using capabilities for this item, but if you are the order in which the initi capabilities happens versus the reading of the NBT data might have to be sorted out -- in other words sometimes the NBT data reads but then the capability can get initialized to overwrite it.

 

But my main point is add console statements so you can actually track the execution and then it should be really easy to see what is wrong.

It is a shield entity.  It is cast by a magic wand. The wand has no nbt/capabilities, It is all stored in the player's capability.

 

Also just did that

The NBT is never read. Do you know how I can fix this?

 

 

Edit: But someting's not right - It's position is saved, That requires NBT reading...

NBT is writing and reading from the disk. You shouldn't be reading from NBT unless you are loading an entity that was not already loaded. Like when you log into a world for the first time, or move into an entity load range. Also Reading and Writing to NBT is a server side method. So if you are hoping to get it to pass something to the client that won't happen. You can probably use IEntityAdditionalSpawnData if that is still a thing...I am stuck in 1.8 for now.

Well, none of my server-to-client data is saved, and I do not get an nbt reading message on world load.

How long does the entity last? You only save to NBT when the chunk unloads. Like when you move far away, or leave the world, of gracefully shutdown a server. If the entity is gone before the chunk unloads, it will never save, and thus never need to load. 

 

read and write to NBT is only to be used to preserver vital entity data when the chunk unloads from the ram. It saves all that data to disk so when the chunk is loaded again, when a player walks close enough, then the entity is brought back into existence. 

 

Cast your charm, them before the entity dies, save and quit out of the world. Reload your world and see if you get an NBT read.

 

Many times I see a crash report because I derped up my NBT read and write on projectiles. So just in the off chance the client is closed while a projectile entity existed, it would safely die or reload when the client was re-opened. 

It is immobile & does not die, I have not made a replacemet for entityThrowable yet, it only extends it because it was the first class that came to mind.

      My server only crashes with the Ticking entity error

      By Giga34 · Posted

      Well, when I log in to the server, sometimes within an hour, sometimes within a minute, the server closes and informs me that there was a Ticking entity error. Below is the crash report

      screen recording problems

      Try switching to Windowed or Borderless Window mode in Minecraft. These modes make it easier for the recorder to capture gameplay, as it still has access to the display without the game taking up all of the graphics resources.

      Forge 55.0 Minecraft 1.21.5

      By Jonathing · Posted

      Forge version: 55.0.0 Minecraft version: 1.21.5 Downloads: As this is the start of a new version, it is recommended that you check the downloads page and use the latest version to receive any bug fixes. Downloads page Intro: Good evening! Today, we have released our initial build of Forge 55.0 for Minecraft 1.21.5. 1.21.5 is the newest member of the 1.21 family of versions, which was released yesterday on March 25, 2025. As a reminder, the first minor (X.0) of a Forge version is a beta. Forge betas are marked as such on the bottom left of the title screen and are candidates for any breaking changes. Additionally, there are a couple of important things to note about this update, which I've made sure to mention in this post as well. Feel free to chat with us about bugs or these implementation changes on GitHub and in our Discord server. As always, we will continue to keep all versions of 1.21 and 1.20 in active support as covered by our tiered support policy. Cheers, happy modding, and good luck porting! Rendering Refactor For those who tuned in to Minecraft Live on March 22, 2025, you may already know that Mojang have announced their intention to bring their new Vibrant Visuals overhaul to Java in the future. They've taken the first steps toward this by refactoring how rendering pipelines and render types are handled internally. This has, in turn, made many of Forge's rendering APIs that have existed for years obsolete, as they (for the most part) can be done directly in vanilla. If there was a rendering API that was provided by Forge which you believe should be re-implemented, we're happy to discuss on GitHub through an issue or a pull request. Deprecation of weapon-like ToolActions In 1.21.5, Minecraft added new data components for defining the characteristics of weapons in data. This includes attack speed, block tags which define efficient blocks, and more. As such, we will begin marking our ToolActions solution for this as deprecated. ToolActions were originally added to address the problem of creating modded tools that needed to perform the same actions as vanilla tools. There are still a few tool actions that will continue to be used, such as the shears tool action for example. There are some existing Forge tool actions that are currently obsolete and have no effect given the way the new data components are implemented. We will continue to work on these deprecations and invite you to chat with us on GitHub or Discord if you have any questions.

      Ore to nuggets and ore rarity mod

      By sailed · Posted

      In summary, a full mod to adjust mining progress in such a specific way does not yet exist in its exact form, but it is possible to find mods that change certain aspects of progression (e.g. "Harder Ores").
