Hello there,

 

So I'm syncing my capability between the server and client, however, when I try to extract mana, I get this error:

I needed to send a packet everytime that it is changed, so in my capability data, I have these:

 

        PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(this.getManaStored()), (EntityPlayerMP) this.getEntity());

In every function that is changing the current mana.

This is where the error occurs however, here is the entire class for reference:

public class CapabilityManaData extends ManaHandler
{
    private EntityLivingBase entity;

    public CapabilityManaData(){
        super(500000);
    }

    public CapabilityManaData(int capacity, int maxReceive, int maxExtract){
        super(capacity, maxReceive, maxExtract);
    }

    public EntityLivingBase getEntity()
    {
        return entity;
    }

    public void setEntity(EntityLivingBase entity)
    {
        this.entity = entity;
    }

    public int extractManaInternal(int maxExtract, boolean simulate){
        int before = this.maxExtract;
        this.maxExtract = Integer.MAX_VALUE;

        int toReturn = this.extractMana(maxExtract, simulate);
        PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(this.getManaStored()), (EntityPlayerMP) this.getEntity());
        this.maxExtract = before;
        return toReturn;
    }

    public int receiveManaInternal(int maxReceive, boolean simulate){
        int before = this.maxReceive;
        this.maxReceive = Integer.MAX_VALUE;

        int toReturn = this.receiveMana(maxReceive, simulate);
        PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(this.getManaStored()), (EntityPlayerMP) this.getEntity());
        this.maxReceive = before;
        return toReturn;
    }

    @Override
    public int receiveMana(int maxReceive, boolean simulate){
        if(!this.canReceive()){
            return 0;
        }
        int mana = this.getManaStored();

        int manaReceived = Math.min(this.capacity-mana, Math.min(this.maxReceive, maxReceive));
        if(!simulate){
            this.setManaStored(mana+manaReceived);
        }
            PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(this.getManaStored()), (EntityPlayerMP) this.getEntity());
        return manaReceived;
    }

    @Override
    public int extractMana(int maxExtract, boolean simulate){
        if(!this.canExtract()){
            return 0;
        }
        int mana = this.getManaStored();

        int manaExtracted = Math.min(mana, Math.min(this.maxExtract, maxExtract));
        if(!simulate){
            this.setManaStored(mana-manaExtracted);
        }
            PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(this.getManaStored()), (EntityPlayerMP) this.getEntity());
           // PlentifulMisc.network.sendToServer(new ManaNetworkSyncServer(this.getManaStored()));

        return manaExtracted;
    }

    public void readFromNBT(NBTTagCompound compound){
        this.setManaStored(compound.getInteger("Mana"));
    }

    public NBTBase writeData()
    {
        NBTTagCompound tag = new NBTTagCompound();
        tag.setInteger("Mana", mana);
        return tag;
    }

    public void readData(NBTBase nbt)
    {
        NBTTagCompound tag = (NBTTagCompound) nbt;
        this.setManaStored(tag.getInteger("Mana"));
    }

    public void writeToNBT(NBTTagCompound compound){
        compound.setInteger("Mana", this.getManaStored());
    }

    public int getPercentedMana() {
        return this.getManaStored() / this.getMaxManaStored();
    }

    public void setManaStored(int energy){
        this.mana = energy;
    }
}

 

The TE thats crashing it:

public class TileEntityChargeStand extends TileEntityCrystalSearchBase {

    public final int MANA_PER_TICK = 50;

    public UUID uuid;

    public TileEntityChargeStand() {
        super("chargeStand");
    }



    @Override
    public void updateEntity() {
        super.updateEntity();
        if(!worldObj.isRemote) {
            System.out.println(storage.getManaStored());

            EntityPlayer player = worldObj.getClosestPlayer(pos.getX(), pos.getY() + 1, pos.getZ(), 1, false);
            if (player != null) {
                if (player.getUniqueID().equals(uuid) && uuid != null) {
                    if (player.hasCapability(CapabilityMagic.MANA, null)) {
                        if (storage.getManaStored() >= 0) {
                            CapabilityManaData cap = player.getCapability(CapabilityMagic.MANA, null);
                            cap.receiveManaInternal(MANA_PER_TICK, false);
                            this.storage.extractManaInternal(MANA_PER_TICK, false);
                        }
                    }
                }
            }
        }
    }


    @Override
    public void writeSyncableNBT(NBTTagCompound compound, NBTType type) {
        if(type != NBTType.SAVE_BLOCK) {
//e            compound.setUniqueId("ChargeUUID", uuid);
        }
        uuid = compound.getUniqueId("ChargeUUID");
        super.writeSyncableNBT(compound, type);
    }

    @Override
    public void readSyncableNBT(NBTTagCompound compound, NBTType type) {
        if(type != NBTType.SAVE_BLOCK) {
        }
        uuid = compound.getUniqueId("ChargeUUID");
        super.readSyncableNBT(compound, type);
    }

}

Sounds like when you're sending it to the client you're not supplying a correct EntityPlayerMP or none at all. Send the correct one. If you're using an event or action you should have the Entity. just check to see if it is the player, then make sure you're on the serverside, cast it to EntityPlayerMP and then use it in your packet

Currently updating my Mod to 1.10.2

      The crash points to moonlight lib - try other builds or make a test without this mod and the mods requiring it

      Do you have shaders enabled? There is an issue with the mod simpleclouds - remove this mod or disable shaders, if enabled
