In my mod I need to set up a GuiScreen that just simply shows the player some of their stats. However, even though the client is synced with the server through packets, I can't get the data in the GUI.

 

The problem is that the

mc.player.getCapability(CapabilityMana.MANA_CAPABILITY, null).get...()

methods return 0.

 

What could be causing this?

Show your syncing code.

Sorry, been coding for 6 hours now, my brain has started to melt. Realized that I'm dumb, and the only data that I didn't sync was what I tried to get from the GUI. Sorry for wasting your time.

Actually, nevermind. Like I said, I'm tired. It's synced.

 

PacketLand:

public class PacketLand implements IMessage {
    private int mana;

    public PacketLand() {}
    
    public PacketLand(EntityPlayer player) {
        mana = player.getCapability(CapabilityMana.MANA_CAPABILITY, null).getLand();
    }
    
    @Override
    public void fromBytes(ByteBuf buf) {
    	mana = buf.readInt();
    }

    @Override
    public void toBytes(ByteBuf buf) {
        buf.writeInt(mana);
    }

    public static class Handler implements IMessageHandler<PacketLand, IMessage> {
        @Override
        public IMessage onMessage(PacketLand message, MessageContext ctx) {
            FMLCommonHandler.instance().getWorldThread(ctx.netHandler).addScheduledTask(() -> handle(message, ctx));
            return null;
        }

        private void handle(PacketLand message, MessageContext ctx) {
        	Main.proxy.handleMana(message.mana, 27);
        }
    }
}

 

Events for syncing:

@SubscribeEvent
    public static void playerClone(final PlayerEvent.Clone event) {
        final IMana oldMana = getMana(event.getOriginal());
        final IMana newMana = getMana(event.getEntityPlayer());

        if (newMana != null && oldMana != null) {
            newMana.setLand(oldMana.getLand());
            System.out.println("Player Clone Event Successful");
        }
    }

@SubscribeEvent
    public static void loginEvent(final PlayerLoggedInEvent event) {
    	EntityPlayer player = event.player;
    	PacketHandler.INSTANCE.sendTo(new PacketLand(player), (EntityPlayerMP)player);
    	System.out.println("Synced");
    }
    
    @SubscribeEvent
    public static void changeDimesionEvent(final PlayerChangedDimensionEvent event) {
    	EntityPlayer player = event.player;
    	PacketHandler.INSTANCE.sendTo(new PacketLand(player), (EntityPlayerMP)player);
    	System.out.println("Synced");
    }
    
    @SubscribeEvent
    public static void respawnEvent(final PlayerRespawnEvent event) {
    	EntityPlayer player = event.player;
    	PacketHandler.INSTANCE.sendTo(new PacketLand(player), (EntityPlayerMP)player);
    	System.out.println("Synced");
    }

 

ClientProxy:

public void handleMana(int mana, int packetType) {
		EntityPlayer player = Minecraft.getMinecraft().player;
		switch (packetType) {
			case 24: player.getCapability(CapabilityMana.MANA_CAPABILITY, null).setLand(mana); break;
		}
	}
