Models

EzInventoryModel

Inventory Model

Inventory is like a bag that stores items owned by game players.
Inventory can have a set capacity and cannot be owned beyond its capacity.

The inventory capacity can be expanded.
It can be set to reward stamp sheets, so any method of expansion is acceptable as long as the stamp sheets can be used to grant rewards.

Type Description
name string Inventory Model Name
metadata string metadata
initialCapacity int Initial Capacity
maxCapacity int Maximum Capacity

EzItemModel

Item Model

Multiple items can be owned for one capacity of inventory, such as potions x 99.
Multiple items owned in one capacity are stacked items. The maximum number of items that can be stacked can be specified for each item.

When the maximum stackable quantity is reached, you can set for each item whether you can reserve a new inventory capacity and own it, or whether it will no longer be available.

Type Description
name string Item Model Name
metadata string metadata
stackingLimit long Maximum stackable quantity
allowMultipleStacks bool Allow items to be stored in multiple slots when the maximum stackable quantity is exceeded?
sortValue int Display order

EzInventory

Inventory

Inventory is like a bag that stores items owned by game players.
The bag has a capacity, and the capacity can be expanded by each player.

Type Description
inventoryId string Inventory GRN
inventoryName string Inventory Model Name
currentInventoryCapacityUsage int Capacity usage
currentInventoryMaxCapacity int Maximum capacity

EzItemSet

Items are the property of the game player

Type Description
itemSetId string Quantity of items held per expiration date GRN
name string Name identifying the item set
inventoryName string Inventory Model Name
itemName string Item Model Name
count long Quantity in possession
sortValue int Display order
expiresAt long Effective date

Consume Item

Use this if you wish to consume items from within the game.

This API is not used to increase or decrease items in conjunction with the GS2 system.
This is because if the consideration is needed to purchase an item or to participate in a quest, you can set the consideration on GS2-Showcase or GS2-Quest, and then use the
This is because items and other resources are automatically consumed as compensation when purchasing products or participating in quests.

Therefore, this API should be used when items are consumed for elements that do not involve GS2.
