Right now I'm mostly developing unique Special Actions for future use in scenarios. So I'm just exploring how I can accomplish things through Lua.

Ah, it was the ":" that I was not using. Lua syntax calls methods differently apparently. Thanks for the help!

I've tried a number of different forms including:
Unit.filterOnComponent('Sensor')
Unit.filterOnComponent(type='Sensor')
Unit.filterOnComponent({type='Sensor'})
...
and several other forms. Was looking for someone who has successfully used the method.

that's a good work around. While we're on the topic, does anyone have any luck using the "filterOnComponent" method? Can't seem to get that to work. I am using it as a method of a Unit instance but maybe I am getting the input format wrong.

This is this possible?
