Systems and methods for visually representing scripted behaviors are provided. A system is disclosed that includes an authoring program executable on a computing device and configured to display a visual scripting interface. The visual scripting interface may be configured to display a plurality of user-selectable graphical building blocks. Each graphical building block may represent a respective component of a script, and may be spatially arrangable within the visual scripting interface to visually represent a script for a target scripted object. Input selectors may be provided on the graphical building blocks to enable users to input script information, and status indicators and messages may also be displayed on the graphical building blocks to inform users whether script information has been properly inputted. Propagation tools may be provided to enable users to successively add new graphical building blocks to build a tree that represents a script sentence.
