[1.12.2] Entity hands not rendering via an inventory

Posted December 16, 20195 yr

I got the human like entity to work but the item holding is not visible until the player interacts the entity. Is there a way that the entity renders the item before the player interact? If not then is there a sample code for it? I made the code so similar to the horse inventory but with only 18 slots.

The base issue is that you aren't synchronizing the entity's inventory to the client (it does not happen automatically until the player interacts with the entity).

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

Then what should I do when trying to synchronize the entity's inventory to the client?

Nevermind. I had to use the !world.isRemote for updating the hands.

Your class indirectly extends EntityLiving, which already has an armor and hands inventory, which is synced to the client. Use it instead of making your own.

That, It works just fine without your suggestion. I just found out that if a inventory of a # of slots. the first slot would be a main hand, and the second would be the off hand. I cannot access the hands inventory if I use your suggestion. Plus the inventory is only 2 slots.

The code has changed. so therefore I extended the living entity to 18 slots, without 4 extra armor slots. Why bother using EntityEquipmentSlot when 18 slots is enough. Do I have to reduce to 2 inventory slots? I saw the code for the AbstactHorse and AbstractChestHorse which those two are synced to the client, and their slots are separate.

Sorry for misclarification, but I saw the code for the AbstactHorse and AbstractChestHorse which those two class that have an inventory are synced to the client. But as for the minecraft chest class is a totally different from the entity living class. I will post these two.

[Not copyrighted code but that code was evidence]

That is why I made the entity having 18 slots.

That wasn't copyright. It was actual evidence. The only downfall with the 6 equipment slots is you can neither access them with a container nor a GUI.

Also please don't delete evidence unless if is it not evidence.

Untrue.

Then How do I make the container with just 6 inventory slots but they don't implement the IInventory interface.

Quote

December 26, 20195 yr

Please read the documentation here. It should help in getting started with the implementing IItemHandler capability.

So the IItemhandler does sync to the client?

Quote

December 26, 20195 yr

You're supposed to sync the data to the client because by default, I don't think the data is synced to the client. This part of the documentation explains it. So basically, you have to sync it yourself using packets.

Oh, I get it. You have to implement the IItemHandler capacity. Where is the IItemHandler capability used in.

Quote

December 26, 20195 yr

You have to make the Entitiy class implement ICapabilityProvider which lets Forge know it's using Capabilities. Then you have to initialise an ItemStackHandler.

Example from a TileEntity from one my previous projects:

private ItemStackHandler inventory = new ItemStackHandler(4);

In the get capability method, you check if the capability wanted is a CapabilityItemHandler.ITEM_HANDLER_CAPABILITY and return the ItemStackHandler.

In the has capability method, you check if the capability wanted is a CapabilityItemHandler.ITEM_HANDLER_CAPABILITY and return true.

Example Code:

@Override
public boolean hasCapability(Capability<?> capability, @Nullable EnumFacing facing) {
	return capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY || capability == CapabilityEnergy.ENERGY
			|| super.hasCapability(capability, facing);
}

@Nullable
@Override
public <T> T getCapability(Capability<T> capability, @Nullable EnumFacing facing) {
	if (capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY)
		return (T) this.inventory;
	else if (capability == CapabilityEnergy.ENERGY)
		return (T) this.energy;
	else
		return super.getCapability(capability, facing);
}

I am just a newbie so sorry if any of the information provided is wrong. I am only speaking from past experience since I had a similar problem with tileentities.

Alright then how do I access the Itemstack handler or IItemhandler if the container requires an old inventory or a gui.

Lastly how do I make sure that the player can interact the entity inventory with only id, player, world, x, y, and z parameters.

I mean, how do I open a gui with right clicking an entity.

Yes, and no. Yes for already for override the process Interact method but no for the open GUI method. The method NetworkRegistry.INSTANCE.registerGuiHandler requires a gui server and gui client but they require parameters world, x, y, z. x, y, z are integers. How on earth do I access the entity gui with only these methods.

Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z);
Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z);

The problem is sometimes the entity is not spawned in the world yet and not the mention they might have the wrong items.

NetworkRegistry.INSTANCE.registerGuiHandler(Issac29Core.instance, new IGuiHandler() {
	@Override
	public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
		try {
			Entity entity = world.getEntityByID(EntityList.getID(EntityHuman.class));
			return new ContainerHuman(player.inventory, ((EntityHuman)entity).inventory, (EntityHuman)entity);
		} catch (ClassCastException ccex) {
			ccex.printStackTrace();
			return null;
		}
	}
	
	@Override
	public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
		try {
			Entity entity = world.getEntityByID(EntityList.getID(EntityHuman.class));
			return new GuiHuman(player.inventory, ((EntityHuman)entity).inventory, (EntityHuman)entity);
		} catch (ClassCastException ccex) {
			ccex.printStackTrace();
			return null;
		}
	}
});

Alright I found out that the Id was made was 38 that executed in the world.getEntityById(38) returns a wrong entity

[12:19:39] [Client thread/INFO] [i29c]: 38
[12:19:39] [Client thread/INFO] [i29c]: null
[12:19:39] [Server thread/INFO] [i29c]: 38
[12:19:39] [Server thread/INFO] [i29c]: EntityCreeper['Creeper'/38, l='[]', x=-314.49, y=46.00, z=-326.83]

Catch exceptions and prevent minecraft to crash in case of runtime exceptions.

Use Entity#getEntityId and World#getEntityByID.

Ok I got that.

Don't just catch random exceptions without having a reason for it and a proper recovery strategy.

Errors happen all the time. Also I removed ClassCastException because there is no reason.

There are four kinds of exceptions:

Fatal. They aren't your fault and there's nothing you can do about it. Let the program crash.
Vexing. They are the result of unfortunate design decisions. Avoid them if you can. If you can't, catch is vexing exceptions.
Exogenous. They are the result of untidy external realities impinging upon your beautiful, crisp program logic. Try it and be prepared to handle the unfortunate realities.
Boneheaded. These are your own damn fault. These are bugs. Never catch these. Fix your code so that it never triggers a boneheaded exception.

A ClassCastException is #4

1. what about runtime, null pointer, arraystore, array out of index, and index out of bounds.

2. @Draco18s I know that by since 2 hours ago from this post.

java.lang.RuntimeException: null (My game refuses to start, and I can't read code

A java.lang.RuntimeException: null occurs when Minecraft tries to run something but fails silently most often due to version mismatches, missing dependencies, or corrupted files. To fix it, ensure your Minecraft version matches the mod, Forge is correctly installed, and there are no conflicting or broken mods. Launching with the proper Forge profile usually resolves it.
