Member Function Documentation

float FMVector2::Length (   )  const [inline]

Retrieves the length of the vector. Returns: The length of this vector.

float FMVector2::LengthSquared (   )  const [inline]

Retrieves the squared length of the vector. Returns: The squared length of this vector.

FMVector2 FMVector2::Normalize (   )  const [inline]

Get a normalized vector with the same direction as this vector. Returns: A vector with length 1 and same direction as this vector.

FMVector2& FMVector2::operator *= (  float  a  )  [inline]

Multiplies this vector by a scaler. Multiplies each of this vector's coordinates with the scaler and returns this vector. Parameters: a  The scalar to multiply with. Returns: This vector.

FMVector2::operator float * (   )  [inline]

Get this vector as an array of floats. Returns: The float array.

FMVector2& FMVector2::operator+= (  const FMVector2 &  a  )  [inline]

Adds two vector. Adds to this vector's coordinates the individual components of the given vector and returns this vector. Parameters: a  The vector to add with this one. Returns: This vector.

FMVector2& FMVector2::operator= (  const float *  f  )  [inline]

Assign this vector to the given float array. Assigns each coordinate of this vector to the elements in the float array. The first element to the first coordinate and the second to the second. It returns this vector. Parameters: f  The float array to assign with. Returns: This vector.
