Hi.
Ak ok.
I believe at this moment when you place a exposed value (inspector parameter) it works as an input, not as output.
But if its a 'global' you do not need to pass it through. you should be able to select it directly inside the fsm.
But its recommended to minimal global variables (
see this wiki)
In the PlayMaker Beta version Run Fsm has a major update which makes the Action a lot more useful, as it can input/output/every frame directly + it will also work with 'Owner'.
If you wish, you can request access to PlayMaker Beta to
Alex or
JeanAs it beta, it is not recommended tho to use in real projects
