Enumerations

The current CLI analyzes enum declarations. Datapack generation for enum assignment still needs work. The examples below show syntax. A working constant-based version follows.

An enumeration names a fixed set of choices. Use it for room states, round stages, and reward kinds.

enum RoundState {
    Waiting,
    Running,
    Finished
}

func main() {
    var state: RoundState = Waiting
    print(state.identifier)
    state = Running
    print(state.identifier)
}

Use a member name when assigning a variable of type RoundState. An enumeration value keeps its member identity as your program passes and stores it.

Specify member values

enum RewardKind {
    Small = 1,
    Large = 5,
    Special
}

func main() {
    var reward: RewardKind = Large
    print(reward.value)
}

Use = to specify a member value. Choose member names that explain the purpose of each option.

A working form for current projects

The current CLI analyzes the enum declarations above. Enum variable assignment still triggers Unbound author-environment value during datapack generation. Use named constants for these states:

const WAITING: int = 0
const RUNNING: int = 1
const FINISHED: int = 2

func main() {
    var state = WAITING
    state = RUNNING
    if (state == RUNNING) {
        print("Round started")
    }
}

This version works in current datapack projects. Runtime generation for complete enum values still needs compiler work.
