Smart Variables

Learn about using smart variables that determine their value at run-time.

In Yarn Spinner 3, smart variables let you create variables whose value is determined at run-time, rather than setting and retrieving a value from storage.

Smart variables give you a simple way to create more complex expressions, and re-use them across your project.

To create a smart variable, declare it like any other variable using the declare statement and provide an expression, rather than a single value:

// A boolean value that is 'true' when the player has more than 10 money
<<declare $player_can_afford_pie = $player_money > 10>>

Smart variables can be accessed anywhere a regular variable would be used:

// Run some lines if the player can afford a pie
<<if $player_can_afford_pie>>
  Player: One pie, please.
  PieMaker: Certainly!
<<endif>>
