We’ve added a few new advanced features to ChoiceScript, and added documentation about them.
*Subroutine support with *gosub (by popular request!)
*Disabling options with *selectable_if, making them unselectable and greyed out
*Easy way to hide options with variables, without complicated indenting
*Easy way to hide options that the player has already used (*hide_reuse, *disable_reuse, *allow_reuse)
More information is available in the Advanced section of the ChoiceScript guide: http://www.choiceofgames.com/blog/choicescript-advanced/
Please let us know if you have questions about the new features, or any other questions about ChoiceScript!
