2 questions. Mobile Touch commands and Casting to Level blueprint?

First, How do I use a Touch command instead of the default joystick?
For instance, If the person reaches a certain part you can click the screen to activate movement.

Next, For some odd reason
When I use “Event play” in the Game mode it doesn’t work
However if I use it in the Level Blueprint it works perfectly.

I made a Blueprint Class that is suppose to regenerate when colliding with box however it’s not activating.
