Private Games

[Code-Over-Time]

Description

Players have expressed a desire to host private games. These are multiplayer games that only certain people are able to join. For example if you want to play with your friend but not any other player.

How it will work:

1. Player 1 creates a new private game and sets a passcode
2. The private game is visible to all players
3. Player 2 doesn't know the passcode so cannot join
4. Player 3 does know the passcode and can join
5. The game continues as normal once both have joined

So this task has work on both the client and server. There needs to be new UI that allows the game creator to specify a passcode. There also needs to be some new UI so the player that is joining can submit a passcode.

There is also server work, as the matchmaker will now need to handle passcode protected games.

Deliverable

• Updated matchmaker API and service that can create private games
• Updated API that verifies passcode on private games
• Updated UI to set passcode
• Updated UI to provide passcode
• Updated matchmaker tests that verify the new logic

Acceptance Criteria

• Players can create a private game with a passcode
• Only players with a valid passcode can join the game

Task Tips!

• You will need to update the Game model in the matchmaker. Make sure to also update the serialization logic too! (This is the code that converts a Game object to JSON and back again).
• You don't need to worry about passcode security, no need to encrypt it or anything like that - they are transient, unlike a user's password - which we take a lot more care of
• Don't forget your unit tests! You can create a short feedback loop by writing tests first and iterating quickly on your matchmaker code. Don't try to test the whole thing end to end from the start - that can be slow and tedious.
