Okay, So my problem was I needed a "Collision2D Event" before I could get the info. My next problem is that when I look at the collision points normal, it's telling which side of the terrain I'm colliding with, rather than what side of the player I'm colliding with. Additionally, with the "Collision2D Event", there are options for On Collision Enter, and On Collision stay, I think want the On Collision Enter, but only when X:-1 or X:1 has been hit. Of course I am not sure of what the best practice is in such scenarios, so I could be wanting something completely different.
Edit:
I was looking at the "Character Controller" component, and It looks like that would allow me to do what I want to do in PlayMaker, but much of the code for movement applies force to the Rigidbody2D, which I cannot have in tandem with a Character Controller. Can the Character Controller be affected in the same ways as the Rigidbody?
