you are asking for A key is down, this will trigger every tick
try using On key A pressed...this will only trigger once...
and play with on key realeased and variables to manage the animation...
look at this capx, jsut imagine the red square frames of animation is the turning animation (sinbce i could not find any animation that has ones).... this is a very easy solution, it may not be what you are looking for since this is very basic, but i think this should give you an idea, you can set an animation to loop to certain frame fo the animation, thats how i loop the walking and not form the begining.... any questions?? i hope this helps...
