Here is what I have so far. The console result is:
GamepadHapticActuator {type: "dual-rumble"}
The console has reported NO errors while playing. The only parameter I changed was duration which I set too 600ms. Interestingly Take Damage IS working. While I will want slightly different durations for the other Autos I left them all the same as Take Damage since that was working. But none of the Autos are triggering rumble.
I added this plugin while I as working on a map and I had an event that I wanted to use rumble with and that worked properly. I used Rumble All as this is a single player game only and if that one person has two controllers hooked up then they can both rumble haha I kept the other settings the same that worked with Take Damage as well..duration and strengths. Not sure why the other Autos aren't working. Deal Damage can be kind of important especially since I have created grenade items to be used to deal damage and if it rumbles when an enemy punches my character then it should definitely when a grenade explodes =0) looking forward to any other feedback at least about the Autos.
