AI BriefingWhy Studio Kingdom Chose Scala for Cookie Run: Kingdom Server Development
Key point
Studio Kingdom adopted Scala for Cookie Run: Kingdom server development to prevent logic errors through the type system and ensure scalability.
Details
Studio Kingdom uses Scala as the game server development language for its hit title Cookie Run: Kingdom. Although it is not a popular language, they consider it an optimal choice for game server development.
Logic Accuracy Based on the Type System
Scala is a statically typed language that prevents runtime errors by defining types at compile time. In particular, it uses the Option[A] type to prevent omissions in null-handling logic, and leverages Refined Types and newtype to clearly specify constraints on values. For example, through types like PosInt, which only allows positive numbers, or KingdomLevel, which is given a specific meaning, incorrect value passing is blocked at the compile stage.
Types That Reveal the Intent of Functions
Types are used as a documentation tool to clarify the behavior of functions. Option[A] indicates the presence or absence of a result, Either[E, A] indicates success/failure, and ZIO[R, E, A] indicates environment dependency and the possibility of side effects. Through these type parameters, developers can immediately grasp what computations and side effects a function performs, and type aliases are used to improve readability.
