Im on a roll tonight! Im trying to get the currentSeason(summer) 'badModifier' and 'goodModifier' values from the Summer object ( both are type Double ) . I am setting 'currentSeason' to String value "Summer". How do i use that String value of "Summer" as an object get. See the code attached. I dont want it to = "Summer", but Summer(the object)

Best way: turn your seasons into an enum!

enum class Season(
  val goodModifier: Double, 
  val badModifier: Double
) {
  Summer(1.20, 0.90),
  Fall(…, …),
  Winter(…, …),
  Spring(…, …)
}

Then you just use valueOf() to get a season by name:

val season = Season.valueOf("Summer").goodModifier

[Sam]

If for some reason you can't use an enum, you could just make a map instead:

val seasons = mapOf("Summer" to Summer, …)

Cheers sam. I think the enum route sounds perfect. I'm guessing these enums can have enless variables inside like any class?

[Sam]

Yes, an enum can do most of what an ordinary class can do. If you need to add a proper class body, you put a semicolon after the list of constants:

enum class MyEnum {
  Foo, Bar;

  val greeting = "Hello, $name"
}

println(Foo.greeting) // "Hello, Foo"

after usung the enum, im still struggling to use the "String" value as an object. Im thinking its not possible.

// Seasons variables
public val currentSeason = findSeason()
public var currentGoodSeasonName = currentSelectedAbility.preferedSeason
public var currentBadSeasonName = currentSelectedAbility.nonPreferedSeason
public var currentGoodSeasonModifier = Seasons.currentSeason.goodModifier
public var currentBadSeasonModifier = currentSeason.badModifier


public enum class Seasons(goodModifier: Double, badModifier: Double, name: String) {
   Summer(1.20,0.90, "Summer"),
   Winter(1.20,0.90, "Winter"), 
   Spring(1.20,0.90, "Spring"),
   Autumn(1.20,0.90, "Autumn")
    
}

[Sam]

Don't forget the valueOf function to get from the String to the object

[Sam]

By the way, enums automatically have a `name`; you don't need to add it yourself

[Sebastian]

im clearly missing something here.. 😕

[Sam]

Just the val keyword in your constructor properties

[Sebastian]

Ohhhhhhhh. OK that works. That makes sense..I think. Still wrapping my head around it lol. If you dont set the constructor as a val, what type are they?

[Sam]

Without val, they're constructor parameters that will be available during initialisation, but not after. Adding the val keyword assigns them to properties that can be accessed later on.

Thank you Sam!!! Your a legend
