Namespace

Namespace is a mechanism that allows multiple uses of the same service for different purposes within a single project. Basically, GS2 services have a layer called namespace, and different namespaces are treated as completely different data spaces, even for the same service.

Therefore, it is necessary to create a namespace before starting to use each service.

CurrentModelMaster

Currently available master data

GS2 uses JSON format files for master data management. By uploading the file, you can actually reflect the settings on the server.

We provide a master data editor on the management console as a way to create JSON files, but you can also create JSON files using the The service can also be used by creating a tool more appropriate for game management and exporting a JSON file in the appropriate format.

Note

Please refer to Master Data Reference of GS2-Matchmaking for the JSON file format.

ScriptSetting

Script settings

In GS2, you can associate custom scripts with microservice events and execute them. This model holds the settings for triggering script execution.

There are two main ways to execute a script: synchronous execution and asynchronous execution. Synchronous execution blocks processing until the script has finished executing. Instead, you can use the script execution result to stop the execution of the API or to tamper with the result of the API.

On the other hand, asynchronous execution does not block processing until the script has finished executing. Instead, you can use the script execution result to stop the execution of the API or to tamper with the result of the API. However, asynchronous execution does not block processing until the script has finished executing, so it is generally recommended to use asynchronous execution.

There are two types of asynchronous execution methods: GS2-Script and Amazon EventBridge. By using Amazon EventBridge, you can write processing in languages other than Lua.

	Type	Require	Default	Limitation	Description
triggerScriptId	string			~ 1024 chars	Script GRN

Enumeration type definition to specify as doneTriggerTargetType

Enumerator String Definition	Description
none	None
gs2_script	GS2-Script

NotificationSetting

Push notification settings

This is a setting for sending push notifications when an event occurs in a GS2 microservice. The push notification here refers to the processing via the WebSocket interface provided by GS2-Gateway, and is different from the push notification of a smartphone. For example, when a matchmaking is completed or a friend request is received, the GS2-Gateway can send a push notification via the WebSocket interface, and the game client can detect the change of the state.

GS2-Gateway’s push notifications can be used to send additional processing to mobile push notifications when the destination device is offline. If you use mobile push notifications well, you may be able to realize a flow in which you can notify the player by using mobile push notifications even if you end the game during matchmaking and return to the game.

	Type	Require	Default	Limitation	Description
gatewayNamespaceId	string	✓	“grn:gs2:{region}:{ownerId}:gateway:default”	~ 1024 chars	GS2-Gateway namespace to use for push notifications
enableTransferMobileNotification	bool?		false		Forwarding to mobile push notification
sound	string	{enableTransferMobileNotification} == true		~ 1024 chars	Sound file name to be used for mobile push notifications

LogSetting

Log setting

This type manages log output settings. This type holds the identifier of the log namespace used to output log data. The log namespace ID specifies the GS2-Log namespace to aggregate and store the log data. Through this setting, API request and response log data under this namespace will be output to the target GS2-Log. GS2-Log provides logs in real time, which can be used for system monitoring, analysis, debugging, etc.
