Final project and some other [silently watching ] make my body thrown into border of reality.
Where did the reality is no matter now.
Dateline for final project always closer second by second.
If there any TIME (refer it as object, not as a flow ) looks free, I'll take it for doing the final project.

Well, it's about Artificial Intelligence. And still no thing that I can shared here
*not because confidential, but yes, I don't know what to shown*

dir = new Vector2(entity.Direction.X, entity.Direction.Z);
cam = Vector2.Normalize(new Vector2(cameraPosition.X - entity.Position.X, cameraPosition.Z - entity.Position.Z));
camAngle = getAngle(cam);

camAngle = (float)MathHelper.ToRadians(camAngle);

camQuat = Quaternion.CreateFromAxisAngle(new Vector3(0, 0, 1), -camAngle);

reassignedDirection = Vector2.Transform(dir, camQuat);

angle = getAngle(reassignedDirection);

if (angle < 45 || angle >= 315)
{
animationPosition.Y = 0;
}
else if (angle >= 45 && angle < 135)
{
animationPosition.Y = 1;
}
