One huge thing is stalking the forums! Sounds very strange, but very often people post tutorials when it comes to advanced directing or tips!
Another thing is simply playing around in the portal and figuring out what works and what doesn’t. Once you’ve become acquainted with the portal, you’ll be much better off and much more accurate. Trust me, coding skills do NOT come over night. It takes time. Lots of research may be necessary while figuring code out, and that’s okay! You’ll definitely get it down in time! With that said, get familiar with the portal and all of its assets. Figure out what each button in the portal does, both in script and outside.
Don’t be afraid to ask questions! Many people, myself included, live in the Directing Help + Tips category. You’re almost guaranteed to get an answer within an hour of posting your question, if not sooner.
