For my tamagotchi mod, I need to assign a player as an owner of a 'gotchi. I've got a tile entity representing the egg, which hatches into an entity, at which point it should start following a player around.

 

So, is it possible to get the player who placed the egg down? If not, what might be a good way of assigning an owner to a new 'gotchi?

Above, and note: you can get player.getUUID() to save player to TileEntity's NBT (one UUID = one player).

To retrieve: MinecraftServer#getEntityFromUuid(UUID uuid) // I think there is player-specific method, yet I don't remember

 

Note: UUIDs are only working on server side.

 

EDIT

Yup, there is: World#getPlayerEntityByUUID(UUID uuid) - but it works per-world.

Note: UUIDs are only working on server side.

 

And only on servers not in offline mode.

(Development dedicated server defaults to offline).

Thanks for all the help! I should be able to figure it out now, but if not, I'll report back.

I can only find World#getPlayerEntityByName(). Is it perhaps a 1.8 feature, or am I missing something?

Might be, you could implement it on your own.

 

public EntityPlayer getPlayerEntityByUUID(UUID uuid)
    {
        for (int i = 0; i < this.playerEntities.size(); ++i)
        {
            EntityPlayer entityplayer = (EntityPlayer)this.playerEntities.get(i);

            if (uuid.equals(entityplayer.getUniqueID()))
            {
                return entityplayer;
            }
        }

        return null;
    }

 

playerEntities is public (in 1.8 ).

For my defence - this is pure vanilla code from 1.8, you think I wouldn't use for each?

Just showing what might not be in 1.7.10.

Turns out it is possible, but it uses World.func_152378_a(UUID).
