Constrain actors position on y axis to where my finger touches screen

bkhoward2001

I have the actor currently constrained to the y axis of where I finger goes once I have place it on top of actor; however, I want to be able to run my finger up and down anywhere on screen and the actor follows my y axis position without me actually being on top of actor.... How do I do this?

Also, on a button, how do you dictate the touch area? It seems like you have to touch it dead center to trigger event.. is the touch area configurable or is it set?

Each actor has a Physics attribute called Collision Shape that can be set to Rectangle, Circle, or Custom. This effects its touchable region.
