Hi,
Learn both! Playmaker will get you a long way without scripting, and this forum is here to help along that journey, but learning Playmaker AND learning scripting is the winning combination really, because then you benefit from all the wonders of playmaker, and you are not dependent on someone else to build your custom actions when you need them.
I never starts a new projects without playmaker... small, big, for testing, for me, for a client... always, and I could do it all with script... but now I don't want to anymore!
bye
Jean
