Animation data is null

I'm trying to change some book code to animate my guy based on his rotation. For whatever reason my _anim* variables are all null as if they are not being set before the process tick is called.
I put default values for them, and they are set in the TXB as well. Not sure what I have to do.
My code is like this:
[TorqueXmlSchemaType(DefaultValue = "orc_forward_northAnimation")]
public T2DAnimationData AnimNorth
{
get { return _animNorth; }
set { _animNorth = value; }
}
SceneObject.Rotation += (move.Sticks[0].X * TurnSpeed);
if (SceneObject.Rotation >= 0 && SceneObject.Rotation < 45)
{
PlayMyAnimation(_animNorth);
}
_animNorth is always null

Anyone know a good way to animate based on rotation? The way I'm trying is not working out too well.

Do you want full 360 degree rotation or something more old school like eight directions?

I probably don't really need to change the rotation though. Maybe I can just change the "direction" that the sprite is considered to be facing and change the animation based on that.
I figured it would look OK if say for example he's facing between 90 and 135 degrees I can just use my east animation and once it gets to 135 use my south east animation.

Well my enemy character only has 8 directional animations, but when he shoots at me or runs to me he comes straight at me. So I was thinking maybe based on his rotation is how I could show the animation.I probably don't really need to change the rotation though.

I implemented a similar directional system for character aiming. It's a side-scroller like Contra that allows for 8 directions of aiming. I created an enumeration for all my directions (East, SouthEast, South, etc.) and stored the current direction in a variable. Then I tested the input angle from the right stick on the gamepad with:
Once I had the angle I ran it through an if...else block like you are talking about to compare the angle with ranges of values. Based on the result I update the current direction and use the newly updated current direction to run animations accordingly.

I'm assuming your perspective is some form of top-down/isometric. In that case I think you would want to change the enemy's rotation so they would move in the proper direction. Think about how movement works in the Space Warrior tutorial - the stick sets the rotation and the move button accelerates you along that vector.I implemented a similar directional system for character aiming.

_angle = T2DVectorUtil.AngleFromInput(new Vector2(move.Sticks[1].X, move.Sticks[1].Y));
