Pakz	Created : 20 February 2024 Edited : 20 February 2024 TriEd Layered Triangle Map Editor
Looking at a screenshot of Gauntlet by Atari from 1985. I was thinking if I could recreate that level using triangles. Hours later I got this basic triangle tile map editor to a working state. I has 2 layers. One big triangle tile map. And a double the amount triangle on top of that with a .5 alpha transparancy, Making use of GPT4 during the development. This seems to be the best LLM so far during my testing. Though, for various 'jobs' different bots seem to be able to do better than the top ones. Making lots of use of the bots now for various questions to increase my skill set now, since getting the subscription to Poe.

Jayenkai	Gosh, that sounds complicated!! Good luck.
