This is so weird, I thought this was possible but when I went to try it last night I couldn't get it to work.
Here's what I want: One active's animation is 4 frames, where the hot spot moves just a few pixels up and down. This gives the appearance of a small 'hop'. I made a second active object which I want to also 'hop' by always setting its position to the first active's hot spot (rather than making it have the same movable hot spot itself).
But for the life of me it's not working. What I get is the first active hops but the 2nd active just follows it around in a stationary position which doesn't hop. I tried using the options for relative to hot spot (and even action point) but no dice there either.
Any ideas on why this doesn't work? It's probably something stupid I missed.
