Elliott this is pretty much like my first suggestion. It works, but if you release either left or right (most of the time the player uses those to navigate where he/she is landing) that will cut the jump short.
So you want to stop the jump prematurely if you release the touch? Sorry it's a little confusing. Not sure why you cant just use touch end?
Yes, that's exactly what I'm trying to do - stop the jump when the jump object is no longer touched, but it seems impossible or at least not straight forward with the given options.
Wherever I looked people talked about this Touch End option, but I don't have such a thing, not just Touch End. I've On Any Touch End that triggers when any of my 3 touch objects is released and On Nth Touch End that triggers on touch count not on object.
