Tuples

Lunaris supports tuples. A tuple is a small fixed group of values that belong together.

function GetLowestAndHighestNumber(input) {
    local min = number.MaxValue
    local max = number.MinValue
    for (i in input) {
        if (i < min) {
            min = i
        }
        if (i > max) {
            max = i
        }
    }
    return (min, max)
}

local numbers = [9, 8, 4, 17]
local lowest, highest = GetLowestAndHighestNumber(numbers) // 4, 17
// The tuple can also be stored in a variable
local result = GetLowestAndHighestNumber(numbers)
print(result[0]) // 4
print(result[1]) // 17

A tuple is different from an array, as an array contains 0 or multiple entries, whereas a tuple is of a fixed size.

A tuple can also be declared as a variable

local position = (10, 20)
print(position[0]) // 10
print(position[1]) // 20
print(position[2]) // Error, as position only contains 2 items

Typing

Tuples also support optional typing

GetSpawnPosition() : (number, number) {
    return (10, 20)
}
