creating a turn based framework with libgdx

I’m somewhat new to programming and newer still to libgdx. I am working on a turn based, tactical, rpg similar to fire emblem or final fantasy tactics, after having worked through some tutorials. So far I have been able to render an enemy, a player, and let the player move in a turn based fashion. Now I want to set up some basic “AI” for the enemy. basically I want it to move along the X axis until it is 1 tile away from the player, but for some reason it is not working. here is the relevant code. if anyone has any help for a newb it is appreciated.
