My Professor wants me to revise my Midterm, however I can’t seem to run the build properly.
I have all the classes and Programs needed, the cypher part of the project must come first before the gameplay program.
Writer [378509] is the original help I had! I would appreciate if they were to take this task but if they’re unavailable that’s fine as well.
Also I do have a question on how moving the player was possible or what method was used.
