This is an engine with a map editor I made. It's mostly based off of Thin Matrix's engine. It's programmed with Java and uses the LWJGL Library. I made it for 'fun' so it's not meant to be a serious competitor to the Unity Engine or something haha. The editor is absolutely terrible and it's overly complicated.
This is a fairly simple python script that scans a folder for images and automatically generates html <img> tags for you. I used it to generate the html for the 4,000 images on this site (warning there's literally over 4,000 images on this site, I wasn't lying. So this may slow down your browser).
