How to use a Capability...(MC1.10.2)

[DesireP]

I want to attach a Capability to the player in order to store some extended information, but I get into trouble, my code is as follows:

(My English is poor....if my expression is strange I'm sorry )

 

CapabilityPlayerData:

public class CapabilityPlayerData{
@CapabilityInject(ICapabilityPlayerData.class)
public static final Capability<ICapabilityPlayerData> INSTANCE = null;

public interface ICapabilityPlayerData {
	public String getType();
	public void setType(String type);
	public int getLevel();
	public void setLevel(int lv);
	public String getProfession();
	public void setProfession(String profession);
}
}

 

CapabilityPlayerDataDefault:

public class CapabilityPlayerDataDefault implements ICapabilityPlayerData{
        private String type = "Human"
        private String profession = "none"
        private int level=0;
@Override
public String getType() {
	return type;
}
@Override
public void setType(String type) {
	this.type = type;
}
@Override
public int getLevel() {
	return level;
}
@Override
public void setLevel(int lv) {
	this.level = lv;
}
@Override
public String getProfession() {
	return profession;
}
@Override
public void setProfession(String profession) {
	this.profession = profession;
}
}

 

CapabilityPlayerDataHandler:

public class CapabilityPlayerDataHandler implements IStorage<ICapabilityPlayerData>{
        public final static CapabilityPlayerDataHandler capabilityPlayerDataHandler = new CapabilityPlayerDataHandler();
        public CapabilityPlayerDataHandler(){}
        
        @Override
        public NBTBase writeNBT(Capability<ICapabilityPlayerData> capability, ICapabilityPlayerData instance,EnumFacing side) {
            NBTTagCompound nbt = new NBTTagCompound();
           nbt.setInteger("level", instance.getLevel());
           nbt.setString("profession", instance.getProfession());
           nbt.setString("type", instance.getType());
            return nbt;
        }

        @Override
        public void readNBT(Capability<ICapabilityPlayerData> capability, ICapabilityPlayerData instance, EnumFacing side,NBTBase nbt) {
            if (((NBTTagCompound) nbt).hasKey("type", )
                    instance.setType(((NBTTagCompound) nbt).getString("type"));
            if (((NBTTagCompound) nbt).hasKey("profession", )
                    instance.setProfession(((NBTTagCompound) nbt).getString("profession"));
            if (((NBTTagCompound) nbt).hasKey("level", 3))
                    instance.setLevel(((NBTTagCompound) nbt).getInteger("level"));
        }
}

 

CapabilityPlayerDataProvider：

public class CapabilityPlayerDataProvider implements ICapabilitySerializable<NBTTagCompound>{
        private Entity player;
        private ICapabilityPlayerData playerCapability = CapabilityPlayerData.INSTANCE.getDefaultInstance();

        public CapabilityPlayerDataProvider(Entity player){
                this.player = player;
        }
        @Override
        public boolean hasCapability(Capability<?> capability, EnumFacing facing) {
                return CapabilityPlayerData.INSTANCE != null && capability == CapabilityPlayerData.INSTANCE;
        }
        @Override
        public <T> T getCapability(Capability<T> capability, EnumFacing facing) {
                if (CapabilityPlayerData.INSTANCE != null && capability == CapabilityPlayerData.INSTANCE) 
                        return (T) new CapabilityPlayerDataDefault();
                return null;
        }
        @Override
        public NBTTagCompound serializeNBT() {
                NBTTagCompound nbt = new NBTTagCompound();
                nbt.setTag("playerData", CapabilityPlayerData.INSTANCE.getStorage().writeNBT(CapabilityPlayerData.INSTANCE, playerCapability, null));
                return nbt;
        }
        @Override
        public void deserializeNBT(NBTTagCompound nbt) {
                NBTBase list = nbt.getTag("playerData");
                CapabilityPlayerData.INSTANCE.getStorage().readNBT(CapabilityPlayerData.INSTANCE, playerCapability, null, list);
        }
}

 

CapabilityPlayerDataProvider

public class CapabilityPlayerDataProvider implements ICapabilitySerializable<NBTTagCompound>{
        private Entity player;
        private ICapabilityPlayerData playerCapability = CapabilityPlayerData.INSTANCE.getDefaultInstance();

        public CapabilityPlayerDataProvider(Entity player){
                this.player = player;
        }
        @Override
        public boolean hasCapability(Capability<?> capability, EnumFacing facing) {
                return CapabilityPlayerData.INSTANCE != null && capability == CapabilityPlayerData.INSTANCE;
        }
        @Override
        public <T> T getCapability(Capability<T> capability, EnumFacing facing) {
                if (CapabilityPlayerData.INSTANCE != null && capability == CapabilityPlayerData.INSTANCE) 
                        return (T) new CapabilityPlayerDataDefault();
                return null;
        }
        @Override
        public NBTTagCompound serializeNBT() {
                NBTTagCompound nbt = new NBTTagCompound();
                nbt.setTag("playerData", CapabilityPlayerData.INSTANCE.getStorage().writeNBT(CapabilityPlayerData.INSTANCE, playerCapability, null));
                return nbt;
        }
        @Override
        public void deserializeNBT(NBTTagCompound nbt) {
                NBTBase list = nbt.getTag("playerData");
                CapabilityPlayerData.INSTANCE.getStorage().readNBT(CapabilityPlayerData.INSTANCE, playerCapability, null, list);
        }
}

 

CapabilityPlayerDataEvent：

public class CapabilityPlayerDataEvent {
        @SubscribeEvent
        public void onTELoad(AttachCapabilitiesEvent.Entity event)
        {
                if(!event.getEntity().hasCapability(CapabilityPlayerData.INSTANCE, null) && event.getEntity() instanceof EntityPlayer)
                        event.addCapability(new ResourceLocation(SOR.MODID+".PlayerData"), new CapabilityPlayerDataProvider(event.getEntity()));
        }
}

 

 

I got two Items for using the Capability . The UserBook is used to show the player's information , and the ChangeLevel is used to change the Level.

 

UserBook:

@Override
        public ActionResult<ItemStack> onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn, EnumHand hand)
        {
                if(!worldIn.isRemote){
                        if(playerIn.hasCapability(CapabilityPlayerData.INSTANCE, playerIn.getHorizontalFacing())){
                                ICapabilityPlayerData inv = playerIn.getCapability(CapabilityPlayerData.INSTANCE, null);
                                playerIn.addChatMessage(new TextComponentTranslation("sor.chat.level.name",inv.getLevel()));
                                playerIn.addChatMessage(new TextComponentTranslation("sor.chat.profession.name",new                                                                                                           TextComponentTranslation("sor.profession."+inv.getProfession()+".name")));
                                playerIn.addChatMessage(new TextComponentTranslation("sor.chat.type.name",new                                                                                                                   TextComponentTranslation("sor.type."+inv.getType()+".name")));
                        }
                }
                return new ActionResult(EnumActionResult.SUCCESS, itemStackIn);
}

 

ChangeLevel:

@Override
        public ActionResult<ItemStack> onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn, EnumHand hand)
        {
                if(!worldIn.isRemote){
                        if(playerIn.hasCapability(CapabilityPlayerData.INSTANCE, playerIn.getHorizontalFacing())){
                                ICapabilityPlayerData inv = playerIn.getCapability(CapabilityPlayerData.INSTANCE, playerIn.getHorizontalFacing());
                                int level = inv.getLevel();
                                inv.setLevel(level+1);
                                playerIn.addChatMessage(new TextComponentTranslation("sor.chat.change.level.name",inv.getLevel()));
                        }
                }
                return new ActionResult(EnumActionResult.SUCCESS, itemStackIn);
}

 

 

I rightclick the UserBook and it said the Player's Level is 1 , and I rightclick the ChangeLevel it said the Level has been changed to 2, but then I rightclick the UserBook again it still said the Level is 1......so what's wrong with it? Thanks
