Member Function Description¶
Constructs a new Vector2 from the given x and y.
- Vector2 abs ( )
Returns a new vector with all components in absolute values (i.e. positive).
- float angle ( )
Returns the result of atan2 when called with the Vector’s x and y as parameters (Math::atan2(x,y)).
Be aware that it therefore returns an angle oriented clockwise with regard to the (0, 1) unit vector, and not an angle oriented counter-clockwise with regard to the (1, 0) unit vector (which would be the typical trigonometric representation of the angle when calling Math::atan2(y,x)).
Returns the angle in radians between the two vectors.
Returns the angle in radians between the line connecting the two points and the x coordinate.
- float aspect ( )
Returns the ratio of X to Y.
Bounce returns the vector “bounced off” from the given plane, specified by its normal vector.
Returns the vector with a maximum length.
Cubicly interpolates between this Vector and “b”, using “pre_a” and “post_b” as handles, and returning the result at position “t”. “t” should be a float of 0.0-1.0, a percentage of how far along the interpolation is.
Returns the squared distance to vector “b”. Prefer this function over “distance_to” if you need to sort vectors or need the squared distance for some formula.
Returns the distance to vector “b”.
Returns the dot product with vector “b”.
- Vector2 floor ( )
Remove the fractional part of x and y.
- bool is_normalized ( )
Returns whether the vector is normalized or not.
- float length ( )
Returns the length of the vector.
- float length_squared ( )
Returns the squared length of the vector. Prefer this function over “length” if you need to sort vectors or need the squared length for some formula.
Returns the result of the linear interpolation between this vector and “b”, by amount “t”. “t” should be a float of 0.0-1.0, a percentage of how far along the interpolation is.
- Vector2 normalized ( )
Returns a normalized vector to unit length.
Reflects the vector along the given plane, specified by its normal vector.
Rotates the vector by “phi” radians.
Slide returns the component of the vector along the given plane, specified by its normal vector.
Snaps the vector to a grid with the given size.
- Vector2 tangent ( )
Returns a perpendicular vector.
