Hi All, new to Playmaker so please bare with me

I am making a 2d top down game. I have a sprite with 4 animations (using animator), 1 for left, 1 for right, 1 for up and 1 for down.
I can't seem to work out how to get the right animation to display, or the right orientation of the sprite depending on which direction the sprite is moving...
Can anyone point me to an example project or offer any help?
Thanks
Dean
