I am also having issues trying to get my spriter imported sprite to function with the platform behavior. I don't know which object to assign it to, the family, the container the object...
The last piece is that the object seems to float above the ground for me once imported which tells me that the image point being used for the overall sprite needs to be moved, however, I can't figure out how to work with it to get it aligned correctly as the pile of parts that appear in Construct 2 doesn't lend itself well to sizing, adjusting image points (No idea where to even start on that one).
Sorry to flood you, I have been reporting Spriter bugs to you on the Spriter site, but have been waiting to report the ones I see when bringing the imported SCML into my construct projects. I figured this is the place to do it.
Thanks again for all your hard work!
