I am an Extreme beginner in unity and I just scrap my lastest project last night due to lack of inspiration and just bad idea so before I sleep I remember soul knight which is a 2d game with a top-down controller
I tried some tutorials in youtube and implementing in with some joysticks but am not successful on that
so I am here finding for help,Hello I am an extreme beginner in UNITY and I scrap my last project due to lack of knowledge and just bad idea and i sat down t think a new project and o think how about a midlevel game with top and down player controller I tried some tutorials but I can’t make it work using cross-platform input in standard assets.
