Would like to try out the new "function" feature of the ChatGPT API.. BUT...

 Development slowed down to a crawl...



Damn you, Lilith!

ChatGPT as a teacher

Bild
Today I came to the conclusion that without a good understanding of asynchronous programming in Javascript, I cannot hope to come up with a game that uses asynchronous events for all player interaction and other asynchronous events to talk to a remote ChatGPT for NPC actions. My code was a mess, and even more important, after 3 refactorings of my game.js class following ChatGPT's suggestions, my mind was a mess as well. And (see other posts) I don't think that handing ChatGPT the control over the overall concepts, design, architecture, is a good idea. So I asked it to explain asynchronous JS programming to me. And it did. Quite exceptionally. See, in normal life you can learn something like this in several ways: You can read a book. I actually have a good JS book. A very, very tedious affair. I have 30+ years of serious programming experience (not counting my "geek teenager programs the heck out of his Sharp MZ-80A with 48K RAM and 1K ROM" time here). A JS book is 95

How it started...

Intro - why this blog? This blog is mostly for people who know software development and would like to understand how ChatGPT can and will change the way we are developing software.  Warning: this is about real (Javascript, Java) code. Back then, in the old days,   I had developed an Android RPG I and a few hundred users found fun. In retrospective it was probably way too complicated for an app. The idea of the game was: turn any web page into a dungeon: words are turned into monsters and weapons - the longer the word the more powerful the monster or weapon. Vowels determine the elements of the monster and weapon, consonants define the behavior of the monster. I also used the web page to dynamically generate the dungeon - nothing you saw was random or pre-thought, all came from the web page.  That was the mighty home page of the game I did: web raid mobile . Reboot, simplified, in Javascript I still like the core idea of fighting complicated words like " butyrylcholinesterase"

Pathfinding and A*

If I want my NPCs to move towards the player on a nxm grid, and the grid can contain trees that the NPC cannot pass, I need an algorithm that finds the shortest path to the player. I gave this as a problem to ChatGPT: In class level I would like to have a new method shortestPath that finds out the shortest path that an NPC on coordinate startX, startY has to take to reach coordinate endX, endY, avoiding any squares where the top levelObject cannot be traversed. The result should be a list of coordinates starting with startX, startY and ending with endX, endY where each coordinate can be reached horizontally, vertically or diagonally from the previous one. To which it responded with: This sounds like a pathfinding problem, which can be solved using various algorithms such as A*, Dijkstra's Algorithm, or Breadth-First Search. Since you want to allow diagonal movement as well, A* would be a good choice here. However, please note that implementing such algorithms in a complex env
