Hi,
PlayMaker events only exists within Fsm, so currently you can't hook to PlayMaker events in scripts. I mentionned this already, and hopefully one day we will have a way to hook to that, but for now, simply forward events one way or another. I do use your technic often, so yes, hacky, but actually necessary. you can also forward directly to a specific class if you implement them in custom actions.
Bye,
Jean
