Vec3.AngleXZ

static Vec3 AngleXZ(float angleDeg, float y)

   
float angleDeg Angle in degrees, starting from (1,0) at 0, and continuing to (0,1) at 90.
float y A constant value you can assign to the resulting vector’s y component.
RETURNS: Vec3 A Vector pointing at the given angle! If y 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 XZ plane, and allows you to specify a constant y value.
