I had an idea to try and make the Triggerbot look more "legit".
You could do it so it follows them right before the it fires (sort of like a flick) so that it's not just a static shot which doesn't look all that legit.
When I say follow, nothing like following their head or anything just moves along slightly in the direction that the target was going giving a fake flick look meaning one tapping people with it looks better.
