Creating branches
You can create branches in your story in a number of ways; through threads, an interactive menus or with a Branch action.
This is what you see when you select a Branch action. There's a box that shows you the conditions for this branch, but currently there are no conditions set. To edit the conditions simply double-click the conditions box.
The condition editor has a couple of buttons on the left hand side. There's an AND-button and an OR-button. These lets you build complex statements such as (A and B) or (A and (B or C)).
The properties of the currently selected statement can be edited on the right hand side
