    is your call the last one in a lambda?

    And you don’t assign the result to some variable? Can we see the code?

    Playing the guessing game is not very efficient here

    well, in this specific case you might use 
    lateinit var batch: SpriteBatch
    and avoid null-safe calls

    But if this generates Unit instances, it’s clearly a bug

    Hi. Trying out some Kotlin for the first time and I’m a bit confused at one thing. Do all properties of a class have to be declared in the constructor? Can I declare new properties in the 
    init
    function?

    you can declare properties as normal, however, they have to be initialized somwhere

    I want to have the property 
    items
    in this class, but I don’t want it to be passed in. Rather the init would create it for me and any calling class would not have to provide a value

    Copy code
    class MainPagerAdapter(val fm : FragmentManager) : FragmetnPagerAdapter(fm) {
  val items : List<GHFragment>
  init {
    items = listOf(…)
  }
}

    @vishnurajeevan: ah that does work! I must have left the declaration in the primary constructor. D’oh. Thanks!

    @vishnurajeevan:
    Copy code
    class MainPagerAdapter(val fm : FragmentManager) : FragmetnPagerAdapter(fm) {
  val items = listOf(…)
}
    would also work there, if you want one line.
