I developed this game as a proof of concept for using the GPT API to improve NPC interactions. The main challenges were:

• Ensuring NPCs stay on-script and provide enough information to encourage players to engage in conversations necessary for game progression.
• Integrating GPT responses with codes that the game logic can parse to update the game state.

• GPT API
• Node.js / Express.js
• HTML Canvas animation
• Game mechanics: Movement, keyboard input, collision detection

• User interaction with GPT taking on various NPC roles
• GPT integration with the app logic to affect game state in order to progress the game

Features I plan to include:

• Refined system prompts that ensure NPCs deliver more predictable responses.
• A complex and challenging storyline that demands increased interaction once NPCs offer consistent feedback.
• Additional game mechanics such as a health meter, enemies, and hearts for health replenishment.
• Game over/won logic that provides end-game feedback and loops back to the start screen.

Step-by-step instructions on how to get the development environment running.

git clone https://github.com/yarrumevets/aigame.git
cd aigame
yarn

Create file in root openaiApiCreds.json with your OpenAi api key in this format:

{
  "openaiApiKey": "xx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}

node server.js

Gameplay:

• Press enter at the start screen
• Use arrow keys to navigate the player
• Press 'T' when prompted to talk to the NPC
