[1.11] Getting a Player's ID

[Lambda]

Hey there,

 

So I have an Item here that need to set a string in a TE ,the string will check if the bounded player is the same, and do x if it is.

 

However, I'm having an issue with finding a way of accessing something that differentiates a player.

 

Thanks,

Best thing is to store the

UUID

of the player. You can get the

UUID

from a player using

Entity#getUniqueID()

. To save it to NBT, save the

getLeastSignificantBits()

and

getMostSignificantBits

result (

longs

). To recreate the

UUID

, use the constructor that accepts 2

longs

(the most and least significant bits) which you saved to NBT.

Okay, so like this:

    public long leastbit;
    public long mostbit;
    public UUID uuid = new UUID(leastbit, mostbit);

 

@Override
    public void writeSyncableNBT(NBTTagCompound compound, NBTType type) {
        if(type != NBTType.SAVE_BLOCK) {
            compound.setLong("UUID.LEASTBIT", uuid.getLeastSignificantBits());
            compound.setLong("UUID.MOSTBIT", uuid.getMostSignificantBits());

        }
        super.writeSyncableNBT(compound, type);
    }

    @Override
    public void readSyncableNBT(NBTTagCompound compound, NBTType type) {
        if(type != NBTType.SAVE_BLOCK) {
            leastbit = compound.getLong("UUID.LEASTBIT");
            mostbit = compound.getLong("UUID.MOSTBIT");

        }
        super.readSyncableNBT(compound, type);
    }

[Lambda]

    @Override
    public void readSyncableNBT(NBTTagCompound compound, NBTType type) {
        if(type != NBTType.SAVE_BLOCK) {
            uuid = new UUID(compound.getLong("UUID.LEASTBIT"), compound.getLong("UUID.MOSTBIT"));
        }
        super.readSyncableNBT(compound, type);
    }

Ah, changed that, test works, but doesnt save, so something is wrong with my NBT still:

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) {
            EntityPlayer player = worldObj.getClosestPlayer(pos.getX(), pos.getY() + 1, pos.getZ(), 1, false);
            if (player != null) {
                if (player.getUniqueID() == 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.extractMana(MANA_PER_TICK, false);
                        }
                    }
                }
            }
        }
    }


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

}

 

Thanks.

Ah didn't catch that.

It saves though relog but not though restart.
