"Setting and Showing Variables": SugarCube (v2.18)
Variables, symbols starting with
$ (for normal) or
_ (for temporary), can be "set" using the
<<set>> macro in SugarCube.
$ is used for storing data throughout the story, and
_ should be used for data only needed in the current passage. Using
_ is useful for not wanting to accidentally overwrite variables elsewhere in the story. They can also help with debugging through not cluttering up the variables list of future passages.
:: StoryTitle Setting and Showing Variables in SugarCube :: Start <<set $numberVariable to 5>> <<set $wordVariable to "five">> <<set $phraseVariable to "The value">> $phraseVariable is $numberVariable and $wordVariable. <<set $numberVariable to $numberVariable + 1>> $phraseVariable is $numberVariable and $wordVariable.
