You can’t just be told what to do, you obviously want to be a great modder and to do that you have to understand what you’re doing.
Most tutorials are from 2014–2018 and are terribly written and put together using bad teaching practices and are very much out of date. I’ve been programming for many years but I’m very new to Sims 4 modding and was ashamed and baffled by the state of Sims 4 scripting tutorials online.
