GS2-MegaField Deploy/CDK Reference

The template format used when creating stacks with GS2-Deploy, and implementation examples of template output in various languages using CDK

Entities

Resources managed by the Deploy operation

Namespace

A Namespace allows multiple independent instances of the same service within a single project by separating data spaces and usage contexts. Each GS2 service is managed on a per-namespace basis. Even when using the same service, if the namespace differs, the data is treated as a completely independent data space.

Therefore, you must create a namespace before you can start using each service.

LogSetting

Log Output Setting

Manages log output setting. 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.

	Type	Condition	Required	Default	Value Limits	Description
loggingNamespaceId	string		✓		~ 1024 chars	GS2-Log namespace GRN to output logs Must be specified in GRN format starting with “grn:gs2:”.

CurrentFieldMaster

Currently active Field Model master data

This master data defines the Field Models currently active within the namespace. GS2 uses JSON format files for managing master data. By uploading these files, the master data are updated on the server.

To create JSON files, GS2 provides a master data editor within the management console. Additionally, you can create tools better suited for game operations and export JSON files in the appropriate format.

Note

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

AreaModel

Area divides space, and different areas can be treated as different spaces even if they have the same coordinates.

	Type	Required	Default	Value Limits	Description
areaModelId	string	*		~ 1024 chars	Area Model GRN * Set automatically by the server
name	string	✓		~ 128 chars	Area Model name
metadata	string			~ 2048 chars	Metadata Arbitrary values can be set in the metadata. Since they do not affect GS2’s behavior, they can be used to store information used in the game.
layerModels	List<LayerModel>		[]	0 ~ 1000 items	List of layer models

LayerModel

Layers allow for multiple logical hierarchies within a single space. For example, it solves the problem of an Enemy being invisible in a space with a large number of characters. Characters are placed on Layer 1. If Enemies are placed on Layer 2, there is no need to worry about them becoming invisible, since each layer can specify the quantity to be acquired within a specified distance.
