Hi,
PlayMaker is strong and alive
can't tell you more, but some important news are brewing under the hood
I would strongly recommand playmaker because you get the best of both worlds. No other visual scripting solution gives you that. you either have to learn how to script, and then you can use visual scripting, because it's not giving you anything else than a visual representation of what would be otherwise a line of code in a text file.
Playmaker brings "FSM" to the table, which is not just for visual scripting. a Finite State Machine is so intuitive, far more thant strict OOP or MVC scripting technics ( and others). Plus PlayMaker has these "actions" which really bring to life dull api functions, by augmenting them with the usual options and tools that go with it, something unique to PlayMaker.
So if your budget allows for it, PlayMaker is the best way to dive into Unity. But of course, your end goal should always be to be understand regular scripting so that one day you can start making your own custom actions for playmaker, and eventually master both, which is the ideal position.
Every single projects since the first day I discovered PlayMaker, for clients or personal, features PlayMaker, and is at the core of all my Unity dev.
Bye,
Jean
