This is a react-based errand running RPG with code written entirely by GPT-4 (via the ChatGPT interface).

See it live here: https://errandrunner.dev/

The original prompt I supplied the model is available in prompt.txt . It took a lot of back and forth to get the game where it is now.

The graphic for the character was created with DALL·E 2.

GPT-4 was able to include some interesting features, including:

• edge & impassable object detection
• map generation
• map swapping (capable of a large map while only displaying a smaller portion)
• a quest system (delivering items)

Two things I was unable to get GPT-4 to do:

1. Maps sliding into view upon map change. When the character touches the edge of a map now, the new map instantly appears. This is a little jarring. I would've preferred for the map to slide into view so the user has a clearer understanding of what to do. After lots of coaxing, I eventually gave up on GPT-4 being able to do this.
2. AI driving. I wanted the character to be driven by a character AI. I tried many methods to coax GPT-4 to write some pathfinding and goal selection code. GPT-4 did try every time, but, seemed to get very confused. Ultimately I gave up.

This game will run like any other create-react-app

npm i
npm run start
