There is no objective here, this project was simply meant to showcase a simple way people could incorporate a 3D element into their projects. keys: Up-move forward Right- turn right Left- turn left Sliders: sensitivity- increases or decreases the speed at which you turn. the horizontal field of view- a lower number makes for decreased view for the player, faster frame-rate (less lag), and bumpier image. a higher number makes for the opposite of all of the following. I would recommend 50 as it has a good balance.
This project runs on one of the most basic ways to simulate a 3D interactive area, ray-casting. If you have questions about this project or just ray-casting in general please ask me in the comments. If I am unable to help you Scratch wiki has a great page about it. -https://en.scratch-wiki.info/wiki/Raycaster I will not lie I read almost all of the 3D related pages inside of scratch wiki.
