SDK v4 Unity¶

This page provides the latest SDK version for Unity engine projects, application guide, and major changes for each SDK release version.

SDK latest version¶

Download the latest SDK version for each target OS environment of your Unity engine project.

※ When installing the SDK distribution file for each target OS, you must also install the Unity Interface.

Version restrictions and dependencies¶

• Security key issuance is required for Hive SDK v4 Unity 25.0.0 or higher
  • Due to changes in the authentication security protocol, when using Hive SDK v4 Unity 25.0.0 or higher, you must issue a security key in Hive Console > Security Key Settings. If you do not issue a security key, you cannot log in to the app.
• PG payment implementation changes required for Hive SDK v4 Unity 25.1.3 or higher
  • For Android & iOS 25.1.3 or higher or Windows 25.1.0 or higher, if you implement PG payment, refer to the PG payment flow and update your PG payment implementation code.
• If using SDK Manager with Hive SDK v4 Unity 25.4.0 or higher, update to SDK Manager v2.0.0 or higher

SDK distribution package application guide¶

From SDK v4 Unity 25.5.1, the SDK distribution package is separated into Interface and Platform OS packages and provided as a total of 4 files as follows.

• Hive SDK v4 Unity Interface 25.5.x
• Hive SDK v4 Unity Android 25.5.x
• Hive SDK v4 Unity iOS 25.5.x
• Hive SDK v4 Unity Windows 25.5.x

The separated SDK files can be applied compatibly according to the package application rules even if their versions are different. If the versions are compatible, you can partially update the SDK distribution package, reducing the time from SDK application to game app release.

The order for applying the SDK distribution package is as follows.

1) Refer to the package application rules to check compatibility between the Hive SDK v4 Unity Interface 25.5.x file you want to download and the SDK file for the target OS (e.g., Hive SDK v4 Unity Windows 25.5.x).
2) Download and import the Hive SDK v4 Unity Interface 25.5.x file you want to apply into your project. In the Unity engine development environment, you must apply the Hive SDK v4 Unity Interface 25.5.x file regardless of the target OS type.
3) Download and import the SDK file compatible with the Hive SDK v4 Unity Interface 25.5.x file you downloaded.

If you use the SDK Manager, you can perform steps 1) to 3) more quickly and easily. Refer to Upgrade SDK with SDK Manager to update to the latest SDK version.

Hotfix version update¶

If only some SDK files in the SDK distribution package are updated to a hotfix version such as v4.25.5.x, the latest SDK version provides the updated hotfix version SDK file (e.g., Hive SDK v4 Unity iOS 25.5.2) along with the previous SDK files that have not been updated.

When updating the SDK distribution package manually (not using SDK Manager), refer to the SDK Unity update guide to update.

If you use the SDK Manager, only the relevant SDK files are automatically updated to the latest hotfix version.
