[1.12.2] Custom Player Capability

[FelipeMunhoz]

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:

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:

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

 

The CommonProxy class:

I don't see you changing the data anywhere.

You should only be modifying the data on the server.

What exactly makes you think the data is not persisting (which symptoms are you observing)?

There is a gui that displays the current cosmo

public class CosmoGUI {
	
	public static class GUIRenderEventClass {

				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.
