So im trying to learn how to create, you know, big boy, i can google stuff, but this is so new i dont know what i dont know, ive figured out how to create unique art styles because im a qualified animator but i really want to play with features like time and gamification, like exp and thresholds like a percentage counter. Im dont expect anyone to teach me but can someone tell me the termanoligy? Like what i can google or resources i can use to create interesting characters?
