vector2::distance
float distance(float vec1_X, float vec1_Y, float vec2_X, float vec2_Y)
Returns the distance to another vector.
vector2::squaredDistance
float squaredDistance(float vec1_X, float vec1_Y, float vec2_X, float vec2_Y)
Returns the square of the distance to another vector.
vector2::normalisedCopy
float2 normalisedCopy(float vec1_X, float vec1_Y)
As normalise, except that this vector is unaffected and the normalised vector is returned as a copy...
vector2::randomDeviant
float2 randomDeviant(float vec1_X, float vec1_Y, float randomAngle)
Generates a new random vector which deviates from this vector by a given angle in a random direction...
vector2::isNAN
int isNAN(float vec1_X, float vec1_Y)
Check whether this vector contains valid values.
vector2::midPoint
float2 midPoint(float vec1_X, float vec1_Y, float vec2_X, float vec2_Y)
Returns a vector at a point half way between this and the passed in vector.
vector2::perpendicular
float2 perpendicular(float vec1_X, float vec1_Y)
Generates a vector perpendicular to this vector (eg an 'up' vector).
vector2::crossProduct
float crossProduct(float vec1_X, float vec1_Y, float vec2_X, float vec2_Y)
Calculates the 2 dimensional cross-product of 2 vectors, which results in a single floating point val...
