static Vec3 AngleXY(float angleDeg, float z)

float angleDeg Angle in degrees, starting from (1,0) at 0, and continuing to (0,1) at 90.
float z A constant value you can assign to the resulting vector’s z component.
RETURNS: Vec3 A vector pointing at the given angle! If z is zero, this will be a normalized vector (vector with a length of 1).

Creates a vector that points out at the given 2D angle! This creates the vector on the XY plane, and allows you to specify a constant z value.
