cee::Vec2f
-
class Vec2f
Vector class for a 2D float vector.
Public Functions
-
Vec2f()
Constructs a null vector.
-
Vec2f(float x, float y)
Constructs a vector from an x and y coordinate.
-
Vec2f &operator=(const Vec2f &other)
Assigns other to this vector and returns a reference to this vector.
-
bool operator==(const Vec2f &rhs) const
Returns true if two vectors are equal, otherwise returns false.
An exact match is required x() == rhs.x(), etc.
-
bool operator!=(const Vec2f &rhs) const
Returns true if two vectors are not equal, otherwise returns false.
Exact comparison is used (!= between floats)
-
const Vec2f operator-(const Vec2f &rhs) const
Returns a vector that is this vector subtracted with rhs.
-
const Vec2f operator*(float scalar) const
Returns a vector that is this vector multiplies with scalar.
-
const Vec2f operator/(float scalar) const
Returns a vector that is this vector divided with scalar.
-
float operator*(const Vec2f &rhs) const
Computes the dot product of this and rhs and return the result (scalar)
Formula:
S = this.x*rhs.x + this.y*rhs.y
-
const float &x() const
X element of the vector.
-
const float &y() const
Y element of the vector.
-
float &x()
X element of the vector.
-
float &y()
Y element of the vector.
-
void set(float x, float y)
Sets x and y value.
-
bool normalize()
Normalizes this vector.
Returns false if the vector is a null vector. Otherwise returns true.
-
float length() const
Returns the length of this vector.
