Node types

• Dialogue Node: Displays character dialogue and visuals
• Choice Node: Offers player dialogue options and branching paths
• If Node: Evaluates variables to control flow that parses a C# if statement passed onto it
• Variable Node: Updates local or global state
• Animator Node: Plays animations on targeted objects
• Audio Node: Plays, pauses, or stops sound clips
• Script Node: Invokes custom methods during dialogue
• To Next Node: Optional node to control UI behaviour
• Add Choice Node: Allows the user to toggle options on the choice node depending on previous choices
