[1.12.2] Custom Player Capability

Posted October 5, 20186 yr

Can someone point me to where I went wrong?

I'm trying to add a new ability to the player, everything works fine,
but the data is not persisting!
Sorry for my english

The CosmoStorage class:

Spoiler

package com.pegasusgamer.saintseiyamod.capabilities.cosmo;

import net.minecraft.nbt.NBTBase;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.nbt.NBTTagInt;
import net.minecraft.util.EnumFacing;
import net.minecraftforge.common.capabilities.Capability;
import net.minecraftforge.common.capabilities.Capability.IStorage;

public class CosmoStorage implements IStorage<ICosmo>{

@Override
public NBTBase writeNBT(Capability<ICosmo> capability, ICosmo instance, EnumFacing side) {

NBTTagCompound tag = new NBTTagCompound();
tag.setDouble("cosmo", instance.getCosmo());
tag.setDouble("cosmo_limit", instance.getLimit());
tag.setDouble("cosmo_regen", instance.getRegen());

System.out.println("Salvando no NBT(Cosmo): "+instance.getCosmo());

return tag;
}

@Override
public void readNBT(Capability<ICosmo> capability, ICosmo instance, EnumFacing side, NBTBase nbt) {

   NBTTagCompound tag = (NBTTagCompound) nbt;
instance.setCosmo(tag.getDouble("cosmo"));
instance.setLimit(tag.getDouble("cosmo_limit"));
instance.setRegen(tag.getDouble("cosmo_regen"));

System.out.println("Carregando do NBT(Cosmo): "+instance.getCosmo());

}

}

The CosmoProvider class:

Spoiler

package com.pegasusgamer.saintseiyamod.capabilities.cosmo;

import net.minecraft.nbt.NBTBase;
import net.minecraft.util.EnumFacing;
import net.minecraftforge.common.capabilities.Capability;

public class CosmoProvider implements ICapabilitySerializable<NBTBase> {

@CapabilityInject(ICosmo.class)
public static Capability<ICosmo> COSMO_CAP = null;

private final ICosmo instance = COSMO_CAP.getDefaultInstance();

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

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

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

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

}

The CapabilityHandler class:

public static final ResourceLocation COSMO_CAP = new ResourceLocation(Reference.MOD_ID, "cosmo");

@SubscribeEvent
public void attachCapability(AttachCapabilitiesEvent<Entity> event) {
if (!(event.getObject() instanceof EntityPlayer)) return;

event.addCapability(COSMO_CAP, new CosmoProvider());
}

}

The CommonProxy class:

       MinecraftForge.EVENT_BUS.register(new CapabilityHandler());

       //Registro dos Eventos
       MinecraftForge.EVENT_BUS.register(new CosmoEventHandler());
   }

   public void init() {}

   public void postInit() {}

   public void registerItemRenderer(Item item, int meta, String id) {}

Você só deve modificar os dados no servidor.

O que exatamente faz você pensar que os dados não estão persistindo (quais sintomas você está observando)?

There is a gui that displays the current cosmo

package com.pegasusgamer.saintseiyamod.gui.overlays;

import com.pegasusgamer.saintseiyamod.capabilities.cosmo.CosmoProvider;
import com.pegasusgamer.saintseiyamod.capabilities.cosmo.ICosmo;
import com.pegasusgamer.saintseiyamod.util.Reference;

import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.FontRenderer;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.server.MinecraftServer;
import net.minecraft.util.ResourceLocation;
import net.minecraft.world.World;
import net.minecraftforge.client.event.RenderGameOverlayEvent;
import net.minecraftforge.fml.common.FMLCommonHandler;
import net.minecraftforge.fml.common.eventhandler.EventPriority;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;

public class CosmoGUI {
	
	public static class GUIRenderEventClass {
		
		@SubscribeEvent(priority = EventPriority.NORMAL)
		public void onRenderGui(RenderGameOverlayEvent event) {
			if (!event.isCancelable() && event.getType() == RenderGameOverlayEvent.ElementType.EXPERIENCE) {			
				
				Minecraft mc = Minecraft.getMinecraft();
				mc.renderEngine.bindTexture(new ResourceLocation(Reference.MOD_ID+":textures/gui/cosmo_bar_overlay.png"));
				
				EntityPlayer player = mc.player;
				ICosmo cosmo = player.getCapability(CosmoProvider.COSMO_CAP, null);		
				
				int posX = event.getResolution().getScaledWidth() / 2 + 10;
				int posY = event.getResolution().getScaledHeight() - 45;
				
				//Retorna caso o player esteja no modo criativo
				if(player.isCreative())
					return;
			
				//Desenha a barra de cosmo na tela
				mc.ingameGUI.drawTexturedModalRect(posX, posY, 0, 0, 81, 5);				
				int barWidht = (int)((cosmo.getCosmo()/cosmo.getLimit())*81);				
				mc.ingameGUI.drawTexturedModalRect(posX, posY, 0, 5, barWidht, 5);
				
				//Desenha o texto com quantidade de cosmo atual e maxima
				int stringSize = ((cosmo.getCosmo()+" / "+cosmo.getLimit()).toString().length()*4);
				mc.fontRenderer.drawStringWithShadow((int)cosmo.getCosmo()+" / "+(int)cosmo.getLimit(), (posX+41)-(int)(stringSize/2), posY-8, -13421569);
				
			}
		}
	}

After you've changed the data of the capability on the server you need to send the changes to the client so the client is aware of the change. GUIs are client side only.
