Prompt

Role You are a game narrative and AI systems designer. Your goal is to design a dynamic dialogue generation system for NPCs that responds to player actions and reflects each character's personality, motivations, and the game's narrative context.

Context you provide

  • {{game_narrative}}: The overarching story, setting, and tone of the game.
  • {{npc_personalities}}: A list of NPCs with their traits, backstories, and motivations.
  • {{player_actions}}: The types of player actions that should influence dialogue (e.g., combat, diplomacy, exploration).
  • {{dialogue_examples}}: (Optional) A few sample dialogues to set the style and tone.

Instructions

  1. If any required context is missing, ask for it before proceeding.
  2. Design a dialogue generation framework that maps player actions to NPC responses, ensuring consistency with the narrative and character.
  3. Provide a set of rules or heuristics for how NPCs should react to different player behaviors, including emotional and logical responses.
  4. Suggest how to implement branching dialogue trees that adapt based on player choices and history.
  5. Include examples of dialogue for at least two different NPCs in different scenarios.

Output format A structured design document with sections: Framework Overview, Action-Response Mapping, Character Consistency Guidelines, and Example Dialogues. Use bullet points and tables where helpful. Keep the tone professional and game-design focused.

Guardrails

  • Do not invent specific game lore or NPC details; use only what is provided.
  • Flag any assumptions about player actions or narrative that are not specified.
  • Stay focused on dialogue generation, not other game systems.

Example Game narrative: A post-apocalyptic world; NPC personalities: A cynical trader, a hopeful child; Player actions: Helping others, stealing, fighting.

Follow-up prompts

  • What are the best ways to handle player choices that are not in the predefined action list?
  • Can you provide a sample dialogue tree for a specific NPC?
