Model

EzRateModel

Exchange Rate Model

The exchange rate is an entity that defines the rate used to exchange resources for resources.

In addition to the rate at which a resource can be exchanged immediately, a rate can also be set at which a resource can be exchanged after a certain amount of time in real time has elapsed. Exchange rates that require an elapse of time in real time can further define the resources required to perform an immediate exchange.

	Type	Require	Default	Limitation	Description
name	string	✓		~ 128 chars	Exchange Rate Name
metadata	string			~ 2048 chars	metadata
timingType	enum [‘immediate’, ‘await’]	✓	“immediate”	~ 128 chars	Type of exchange
lockTime	int	{timingType} == “await”		~ 525600	Waiting time (minutes) from the execution of the exchange until the reward is actually received
consumeActions	List<EzConsumeAction>		[]	~ 10 items	List of Consumption Action
acquireActions	List<EzAcquireAction>		[]	~ 100 items	List of Acquire Action

EzIncrementalRateModel

Cost increase type exchange rate model

Normal exchange rates always provide exchanges at a constant rate. With incremental exchange rates, you can define a rate that increases in cost as the number of exchanges increases. For example, the first exchange can be exchanged at a rate of 1:1, but the second exchange can be exchanged at a rate of 2:1. By defining such a rate, you can increase the value of the resources obtained by the player as the game progresses.

The number of exchanges can be reset by the passage of real time. This is useful for resetting the number of exchanges on a daily or weekly basis.

Warning

This event is called when the value in the local cache that the SDK has is changed.

The local cache will only be changed by executing the SDK’s API, or by executing a stamp sheet via GS2-Distributor with GS2-Gateway notification enabled, or by executing a GS2-JobQueue with GS2-Gateway notification enabled. GS2-Gateway notification enabled.

Therefore, callbacks will not be invoked if the value is changed in any other way.

This event is called when the value in the local cache that the SDK has is changed.

Therefore, callbacks will not be invoked if the value is changed in any other way.
