Where would you store data that multiple players must have access to?

I am implementing a Party system (groups).

I am struggling with where to store which players are connected into group.

I see these options:

schema of the map
The big disadvantage is that I could store this only per map
Schema of the player
Disadvantage is that I would need to copy data between players who belongs to group
Separate Model/Entity in Database
I think it would be non-optimal because of the number of reads and saves to db (but for now I selected this option)

I know that player progress is saved in memory and periodically we can use player.save to save to db with the title screen plugin.
But I don't know how could I accomplish something like this with groups which must be shared between players.

If anyone has experience with how to do such operations in games I would appreciate every help.

Hello, I faced the same difficulty of where to store battle information in the model I am making. I believe the best way would be to have a model of where to save this information on the server, something like: "server.groups".

To be able to do this, I stored it in the player's schema. Save an ID and all players who have that ID in their scheme can have access to view each other's HP or share experience.

In short: if I were to do it, it would be in the player's scheme.

Wow, I didn't think of it.

So you save full information to server.groups and the player has only the group ID assigned right?

I see an edge case where it would not work, like having multiple server instances.
well unless players are on the same map.

however, to have multiple instances of servers is still a long way off for me.

Thank you!

Is it possible for me to implement automatic synchronization between client and server not for the Player or Map, but for a Game as a whole?

For example:

inject(RpgServerEngine).groups = [
  {
    members: [
      {
        id: '4sajd9'
        name: 'Player A',
      },
      {
        id: '4218sd'
        name: 'Player B',
      },
    ]
  }
]

next, read this on the client side for example like this?:

inject(RpgClientEngine).groups

If there is no such mechanics to make it work, do you now some tool to do it?

I saw that you synchronize objects, shapes in similar way using rxjs?

I need this because I want to display on the client side other group members' statistics.

At present, you can only synchronise data in a map (=room)
At the moment, you have to send the data in the traditional way using socket.io

But I like the idea

Thank you! I will try to achieve that with socket.io
