I am new to unity and scripting. How hard would it be to make a game that has similar gameplay to Doom or Duke3d with sprites for weapons and enemies and all the powerups? I want to have keycards to open doors and moving platforms too. Im gonna make all the levels in Blender.
player abilities - moving, shooting, jumping, collecting basic items
AI - shooting back, moving (few enemy types)
game - opening doors, moving platforms
if you want to have only that things in game it can take one day if you’re really good at scripting. depends on your skill. I would say 1week for myself.
but I’m not rly advanced. It will take you few years to learn all the stuff that Unity is giving you.
