Méthode	Description
Cross ( Vec2 a, float s ) : Vec2	Perform the cross product on a vector and a scalar. In 2D this produces a vector.
Cross ( float s, Vec2 a ) : Vec2	Perform the cross product on a scalar and a vector. In 2D this produces a vector.
Cross ( Vec2 a, Vec2 b ) : float	Perform the cross product on two vectors. In 2D this produces a scalar.
Distance ( Vec2 a, Vec2 b ) : float
DistanceSquared ( Vec2 a, Vec2 b ) : float
Dot ( Vec2 a, Vec2 b ) : float	Peform the dot product on two vectors.
Length ( ) : float	Get the length of this vector (the norm).
LengthSquared ( ) : float	Get the length squared. For performance, use this instead of Length (if possible).
Normalize ( ) : float	Convert this vector into a unit vector. Returns the length.
Set ( float x, float y ) : void	Set this vector to some specified coordinates.
SetZero ( ) : void	Set this vector to all zeros.
Vec2 ( float x, float y ) : System	Construct using coordinates.
operator ( ) : Vec2
operator ( ) : bool
