SQLite functions will be handled by Unreal Engine 4's blueprint. Structures can be constructed directly as columns of tables and serialized data can be handled.
I am Japanese and I am using machine translation because I do not have English writing skills.
This plug-in created as one of Mitsunagi Studio's Utility Toolkits (MUTK) wraps the functions of SQLite, and it can be linked with Blueprint.
Currently supported functions are as follows.
This plug-in is one of the byproducts that I myself made for game development, and functions may be expanded or changed in the future.
