Necro time!
If someone wants to use "official" events, one would preferably use the Analytics Event Tracker component.(1) It comes with a full array of events and associated parameters that Unity collects.
If you expand the Rules region of the component, create a rule and drop a FSM component into the first field, Target, then press on the button to the right of it, by default titled "No Field", it will throw a lengthy error.
This was a quick test to see how by default both Playmaker and this Unity tool communicate. The issue is present too when trying to forward data into parameters associated to any native event sent to the Dashboard.
So is there any way for Playmaker to talk to this component, like through some kind of proxy? The official component wants to interface with delegates.
(1) This is obtained after installing Analytics Library from the Package Manager. It contains the standard events so don't install the other package known as Analytics Standard Events otherwise it will create conflicts. Also, Validator has been removed from the Services / Analytics tab since Jan 16th 2021.
