[1.12.2] Getting a player capability for render

Posted July 22, 20196 yr

Hello!

I'm trying to render a new layer on the player model, which we be scaled differently based on a value stored in the player capabilities.
I got the rendering to work, the capability too, but now i'm trying to retrieve the value from the capability to modify on the fly the scaling.
However, the capability always return the base value (0.0) when I try to view the player model in the inventory, or using F5, and of course it doesn't work in multiplayer too.

What could be the problem?
I've attached a screenshot to show the chain of events I'm logging into the player chat.

This is my Event Handler

@Mod.EventBusSubscriber
public class HyperEventHandler {

  private final PSizeModifier pSizeModifier = new PSizeModifier();
  private IPSize pSize = null;

  @SubscribeEvent
  public void onPlayerLogsIn(PlayerLoggedInEvent event)
  {
    EntityPlayer player = event.player;
    if(player instanceof EntityPlayerMP)
    {
      pSize = player.getCapability(PSizeProvider.SIZE_CAPABILITY, null);

      IMessage msgSize = new SizeSyncPacket.SizeSyncMessage(pSize.getSize(), 0.0F, player.getEntityId());
      HyperPackets.net.sendToAll(msgSize);
      player.sendMessage(new TextComponentString("Size : " + pSize.getSize()));
    }
  }

  @SubscribeEvent
  public void onPlayerUpdate(LivingUpdateEvent event)
  {
    if(event.getEntity() instanceof EntityPlayer)
    {
      EntityPlayer player = (EntityPlayer) event.getEntity();

      if(!player.world.isRemote)
      {
        pSizeModifier.onPlayerUpdate(player);

        IMessage msgSize = new SizeSyncPacket.SizeSyncMessage(pSize.getSize(), 0.0F, player.getEntityId());
        HyperPackets.net.sendToAll(msgSize);

    final IPSize original = PSizeProvider.getPHandler(event.getOriginal());
    final IPSize clone = PSizeProvider.getPHandler(event.getEntity());

  private static boolean layerAdded = false;

      Minecraft.getMinecraft().getRenderManager().getSkinMap().get("slim").addLayer(new LayerCube(event.getRenderer()));
      layerAdded = true;
    }
    if(event.getEntity() instanceof EntityPlayer)
    {
      IPSize pSize = event.getEntityPlayer().getCapability(PSizeProvider.SIZE_CAPABILITY, null);

      player.sendMessage(new TextComponentString(player.getDisplayNameString() + " : " + pSize.getSize()));
    }
  }

}

The SizeSyncPacket class

public class SizeSyncPacket implements IMessageHandler<SizeSyncMessage, IMessage> {

  public SizeSyncPacket(){}

  @Override
  public IMessage onMessage(SizeSyncMessage message, MessageContext ctx) {

    if(ctx.side.isClient())

      float pSize = message.pSize;
      float bSize = message.bSize;

      //Attempt to synchronise capability using the Entity ID
      Minecraft.getMinecraft().addScheduledTask(() -> {
       Entity player = Minecraft.getMinecraft().world.getEntityByID(message.entityID);
       if(player == null)
         return;
       IPSize ppSize = player.getCapability(PSizeProvider.SIZE_CAPABILITY, null);	//TODO: Rename this with a clearer name
       if(ppSize != null)
         ppSize.set(pSize);
       });
    }

    return null;
  }

  public static class SizeSyncMessage implements IMessage
  {

    private float pSize;
    private float bSize;
    private int entityID;

    public SizeSyncMessage(float pSize, float bSize, int entityID)
    {
      this.pSize = pSize;
      this.bSize = bSize;
      this.entityID = entityID;
    }


    @Override
    public void fromBytes(ByteBuf buf) {
      this.pSize = buf.readFloat();
      this.bSize = buf.readFloat();
    }

    @Override
    public void toBytes(ByteBuf buf) {
      buf.writeFloat(pSize);
      buf.writeFloat(bSize);
    }
  }


}

If you think the problem might be elsewhere than these 2 classes, please feel free to tell me!

Your packet does not have a 0-parameter constructor. The game should vomit an error when your packet is sent.

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.

Where should I move the RenderPlayerEvent?

Changed, in my case, is it better to use START or END ?

Spoiler


 @SubscribeEvent
  public void onPlayerUpdate(PlayerTickEvent event)
  {
    if(event.phase == Phase.START) {
      EntityPlayer player = event.player;
      if (!player.world.isRemote) {
        pSizeModifier.onPlayerUpdate(player);

        IMessage msgSize = new SizeSyncPacket.SizeSyncMessage(pSize.getSize(), 0.0F, player.getEntityId());
        HyperPackets.net.sendToAllTracking(msgSize, player);
        HyperPackets.net.sendTo(msgSize, (EntityPlayerMP) player);
      }
    }
  }

Removed the check
How can I check if the value has changed? Should I simply store it temporarily and then send it if the temp value is different than the current value?

Applied everything, is this correct?

Okay, moved all rendering to a separate class

Spoiler


@Mod.EventBusSubscriber(value = {Side.CLIENT})
public class HyperClientEventHandler {

  @SubscribeEvent
  public void onHandRender(RenderHandEvent event)
  {
    //TODO: Fill this up
  }
  private static boolean layerAdded = false;

  @SubscribeEvent
  public void onPlayerRender(Pre event)
  {
    EntityPlayer player = (EntityPlayer) event.getEntity();
    if(!layerAdded)
    {
      Minecraft.getMinecraft().getRenderManager().getSkinMap().get("default").addLayer(new LayerBalls(event.getRenderer()));
      Minecraft.getMinecraft().getRenderManager().getSkinMap().get("slim").addLayer(new LayerBalls(event.getRenderer()));
      layerAdded = true;
    }
    if(event.getEntity() instanceof EntityPlayer)
    {
      IPSize pSize = event.getEntityPlayer().getCapability(PSizeProvider.SIZE_CAPABILITY, null);

      player.sendMessage(new TextComponentString(player.getDisplayNameString() + " : " + pSize.getSize()));
    }
  }

}

So I just need to remove onPlayerUpdate of my code, alright

Sending the packet each time the setter is called

Spoiler


  private void sendUpdate(EntityPlayer player)
  {
    IMessage msgSize = new SizeSyncPacket.SizeSyncMessage(getSize(), 0.0F, player.getEntityId());
    HyperPackets.net.sendToAllTracking(msgSize, player);
    HyperPackets.net.sendTo(msgSize, (EntityPlayerMP) player);
  }

  @Override
  public void set(float size, EntityPlayer player) {
    this.size = size;
    sendUpdate(player);
  }

  //Same thing for the other corresponding methods

EDIT : Okay, the problem is, by doing it like this it break my readNBT method of my storage class, since i'm calling instance.set(), and now it need an EntityPlayer to be passed, I don't see an obvious way to specify it tho
Removed sendToAll()

Sorry about the copy pasting, bad habit of mine. Moved every similar packet related things into a private sendUpdateMessage() method.

I do not see an obvious way to specify it tho, simply using Minecraft.getMinecraft().player doesn't work and simply result in a NullPointerException

@Override
public void readNBT(Capability<IPSize> capability, IPSize instance, EnumFacing side, NBTBase nbt) {
  if(nbt instanceof NBTTagCompound)

    NBTTagCompound compound = (NBTTagCompound) nbt;

I thought you meant the setters of my capability, but I suppose it was something else?

Hmm. I'm having trouble understanding what you want me to do then...
Right now, my AttachCapabilitiesEvent looks like this

Spoiler


  private static final ResourceLocation PSIZE_CAP = new ResourceLocation(Hyper.MOD_ID, "PSize");

  @SubscribeEvent
  public void attachCapability(AttachCapabilitiesEvent<Entity> event)
  {
    if(!(event.getObject() instanceof EntityPlayer)) return;
    event.addCapability(PSIZE_CAP, new PSizeProvider());
  }

My PSizeProvider class looks like this

Spoiler


public class PSizeProvider implements ICapabilitySerializable<NBTBase> {

  @CapabilityInject(IPSize.class)
  public static final Capability<IPSize> SIZE_CAPABILITY = null;

  private IPSize instance = SIZE_CAPABILITY.getDefaultInstance();

  @Override
  public boolean hasCapability(Capability<?> capability, EnumFacing facing) {
    return capability == SIZE_CAPABILITY;
  }

  @Override
  public <T> T getCapability(Capability<T> capability, EnumFacing facing) {
    return capability == SIZE_CAPABILITY ? SIZE_CAPABILITY.<T> cast(this.instance) : null;
  }

  @Override
  public NBTBase serializeNBT() {
    return SIZE_CAPABILITY.getStorage().writeNBT(SIZE_CAPABILITY, this.instance, null);
  }

  @Override
  public void deserializeNBT(NBTBase nbt) {
    SIZE_CAPABILITY.getStorage().readNBT(SIZE_CAPABILITY, this.instance, null, nbt);
  }

  public static IPSize getPHandler(Entity entity)
  {
    if(entity.hasCapability(SIZE_CAPABILITY, null))
      return entity.getCapability(SIZE_CAPABILITY, null);
    return null;
  }

}

Knowing this, how can I

Okay, I've done it like this

  public void attachCapability(AttachCapabilitiesEvent<Entity> event)

    if(!(event.getObject() instanceof EntityPlayer)) return;
    event.addCapability(PSIZE_CAP, new PSizeProvider((EntityPlayer) event.getObject()));

I've put this in the Provider

Spoiler


  public static EntityPlayer player;

  public PSizeProvider(EntityPlayer player)
  {
    this.player = player;
  }

And I simply access it like this

Spoiler


@Override
  public void set(float size) {
    this.size = size;
    sendUpdate(PSizeProvider.player);
  }

Doing this do raise some exception tho; so I must be doing something wrong again eh...

I cannot access PSizeProvider.player otherwise

I suppose I misunderstood how you wanted me to store/retrieve EntityPlayer from the Provider

And yes I do understand what static means, I just didn't thought about this when I wrote this, sorry

Okay hmm...
I... do not see how I could pass the player to the capability.
Could you give me an example? Because i'm getting a bit lost right now...

I was away for a few days, so sorry for the late response, I think I finally understood now
So, before, my instance was created like this:
private IPSize instance = SIZE_CAPABILITY.getDefaultInstance();

This is how I've seen every capability instance being created in the examples that I found
I suppose that wasn't good, since I can't pass the player this way, so instead i'm doing this:
private IPSize instance = new PSize(player);

Where player is set trough the constructor of the Provider

Spoiler


  private EntityPlayer player;
  public PSizeProvider(EntityPlayer player)
  {
    this.player = player;
  }

This should be good (?), but again I'm not 100% sure this is correct, and what's you're expecting me to do
The constructor of PSize is simply this

Spoiler


  private EntityPlayer player;
  public PSize(EntityPlayer player)
  {
    this.player = player;
  }

and player is used by sendUpdate() that I detailed in earlier posts

However, I get a NullPointerException when deserializeNBT() is called, so I suppose that somehow player in the Provider isn't set correctly?...

Spoiler

I'm sending updates each time I'm calling the set/add/rem of my capability, are they reading from NBT?

Quote

July 29, 20196 yr

So then, instead of callingsendUpdate() in my set() like this

Spoiler


  @Override
  public void set(float size) {
    this.size = size;
    sendUpdate();
  }

I should instead call it each time after I use set(), like this?

Spoiler


    IPSize size = player.getCapability(PSizeProvider.SIZE_CAPABILITY, null);

    size.add(1.0F);
    sendUpdate(player);

I don't see where or when I'm reading from NBT though
Again, I'm a bit lost (but things works like I want them to right now)

Quote

July 29, 20196 yr

Yes, but I'm not calling set() in my Provider, I'm calling it in a separate class

Quote

July 29, 20196 yr

Okay, removed my set() calls from there

What's the proper way to change my values though?

I don't know that either - newer worked with Invision Community 😕

The Forum/Guides show a customized toolbar:
https://invisioncommunity.com/4guides/themes-and-customizations/editor-and-emoticons_327/customizing-editor-toolbars-r132/
But I have no idea if this applies to v5

Regarding the Forum, "Mark all as read" seems to be hidden as default but is available if I click on my profile:
https://invisioncommunity.com/forums/topic/481218-fix-for-unreadmark-read/

I saw that it works here and also fixes the one unread thread mentioned in my first post - so I had just overlooked it

The toolbar changes are just QoL - if there is no way to change it at the moment, that's fine

I understand what you're asking for, but I don't know how to do that. The settings have moved around a bit in the admin panel and I can no longer see a way of customising the editor. If you know how to customise the editor in Invision Community 5, let me know and I'll try applying it.

I also noticed that there is no way to upload images directly into a post
There is only "Other Media - Insert existing attachment"

Yeah I saw, he just mentioned Fabric so I was wondering when it would be out.
@FoxyWoxy
When you are near (1-12ish blocks) the stab shot when it hits, the player gets launched around 50-100 blocks in the air
