ZScript is undocumented shitcode to be perfectly honest, so jumping directly in will be hard if you don't have a good grasp on OOP. Assuming you're either ok with that or are quite good at OOP, rip apart some simpler DECORATE mods to get a grasp of the old stuff, then unzip the gzdoom pk3 and use it as a reference. There were some ok bitchute videos a while back on this but idk if they're still up.
ACS is another ballgame, but there's a lot of code of it floating around. However, all that being said, the best way to learn is to just try to make shit. Start simple and work your way up.
