I just spent the past couple hours reinstalling Playmaker a half dozen times, and I'm happy to report that it is finally WORKING!
I have at least 6 saved projects that are BORKED, but the sun came out and eased my pain, and the last install actually works.
I did two things different with this last install. I have no idea if they made the difference or not, I'm too happy to care right now.
In the previous installs I had used the Unity Store to do the installs, using my user download area and the import button. This last time I imported the base Playmaker at the time I created the project using the list of available packages at creation time. Then I imported the WP8 Addon from the menu option.
Secondly, I had been deleting the Networking Assets directory. This time I also deleted the Playmaker Network Actions.
I rebuilt the simple FSM and published and it worked. Yikes, what a roller coaster ride.
So I dropped back to Unity v4.3.2, and it is my understanding that I need to stay at this version until Unity makes some fixes, correct?
Also, I still see the warning about mouse events, which is annoying, but not a problem, correct?
And finally, the Action>Device>iPhone Settings is by design, correct?
The first thing I have done now is to export a WORKING package of the Playmaker Install. I will use this package to start new WP8 projects.
Thank you,
