Models

EzGathering

Gathering

An entity representing a group of game players brought together by matchmaking.
It has multiple parameters for matchmaking, and the players are grouped based on the totality of the parameters.

	Type	Description
gatheringId	string	Gathering GRN
name	string	Gathering Name
attributeRanges	List<EzAttributeRange>	Terms and Conditions
capacityOfRoles	List<EzCapacityOfRole>	List of application limit
allowUserIds	List<string>	User ID allowed to participate
metadata	string	metadata
expiresAt	long	Gathering expiration date
createdAt	long	Datetime of creation
updatedAt	long	Datetime of last update

EzRatingModel

Rating Model

GS2 uses Glicko-2 as its rating algorithm.
Glicko-2 has several parameters, but GS2-Matchmaking aggregates them into a single parameter, volatility, which represents the totality of the parameters.
Volatility is a parameter that expresses the magnitude of change; the larger the value, the greater the change in the rating value.

	Type	Description
name	string	Rating Model Name
metadata	string	metadata
volatility	int	Magnitude of rate value fluctuation

EzAttributeRange

	Type	Description
name	string	Attribute Name
min	int	Minimum attribute values that can participate in the Gathering
max	int	Maximum value of attributes that can participate in the Gathering

EzCapacityOfRole

	Type	Description
roleName	string	Role Name
roleAliases	List<string>	List of Role Name Aliases
capacity	int	Number of applicants
participants	List<EzPlayer>	List of Participant Players

EzAttribute

	Type	Description
name	string	Attribute Name
value	int	Attribute value

EzPlayer

	Type	Description
userId	string	User Id
attributes	List<EzAttribute>	List of Attributes
roleName	string	Role Name
denyUserIds	List<string>	List of user IDs that are denied participation

EzRating

Rating

An entity that holds the current rating value for each game player.

	Type	Description
ratingId	string	Rating GRN
name	string	Rating Name
userId	string	User Id
rateValue	float
createdAt	long	Datetime of creation
updatedAt	long	Datetime of last update

EzGameResult

	Type	Description
rank	int	Rank
userId	string	User Id

EzBallot

	Type	Description
userId	string	User Id
ratingName	string	Rating name used for rating calculations
gatheringName	string	Name of Gathering to be voted
numberOfPlayer	int	Number of participants

EzSignedBallot

	Type	Description
body	string	Data for ballot signature targets
signature	string	Signature

EzTimeSpan

	Type	Description
days	int	Number of days from current time
hours	int	Hours from current time
minutes	int	Minutes from current time

Cancel Matchmaking and leave the Gathering in which you are participating.

If matchmaking is completed before leaving the gathering, a NotFoundException (404 error) will be raised and failure will occur.

Create a new Gathering

The user ID for the player's own player information specified in Player can be omitted.
The expiration date of the gathering can be set by specifying "expiresAt".
If no expiration date is used, old gatherings will remain, and when a match is made
The user may have left the game.
If you use an expiration date, you should prompt the user to recreate the gathering each time the expiration date comes up.

Find and join a gathering that you can participate in among those that already exist.

Search for a certain period of time and return a matchmaking status token if the target is not found.
Next time, you can resume the search process from the previous time by submitting a request again with a token to keep the matchmaking status.
When all gatherings are searched but there is no gathering to join, null is returned for both the gathering and the token.

Vote on the results of the matchups.

Voting must take place within 5 minutes of the first vote being cast.
This means that the results will not be reflected immediately, but approximately 5 minutes after the start of voting or when all players have cast their votes.
If all ballots are not collected within 5 minutes, the result will be determined by a majority vote based on the votes cast at that time.
If the number of votes for each result is the same, the result will be discarded (the behavior can be changed by script).

If you want to reflect the result immediately, the representative player of the winning side can collect ballots from each player and call voteMultiple to reflect the result immediately.

Vote on the results of the matchups together.

The side that wins the game collects the ballots of other players and uses them to vote collectively.
We say 'the winning side' because there is an incentive for the losing side to report that they won, but not vice versa.
It is possible that the losing side will not hand in their ballots, but even in that case, if there is a majority of ballots, the results can still be passed.
