Trying this again, what I'm trying to do is select an actor after clicking it so that when i have clicked an actor i can press w,a,s or d to get my actor to move either up, down, left or right and after the actor have moved for it to become un-selected again.
I have tried this a couple of different ways and haven't been able to get any of them to work, actually if I could just get one tile to move in a direction when i click on it i would be thrilled but I can't.
here's a picture of what my world looks like: 
The blue background is made from me using a class that creates a mini-world withing a world so as to get the grid working.
I suspect that there is something in my PIP actor or my world actor that is blocking the mousePressed on each of the tile actors and making it click on the PIP element instead and I can't quite figure out which thing in my code that might be causing this.
World actor:
PIP actor:
and the tile actor with the selection/move script aka my Sword actor
