Chipmunk's 2D vector type.
Constructors
Returns the unit length vector for the given angle (in radians).
lerp(v1 :
Vect, v2 :
Vect, t :
Number) :
Vect Linearly interpolate between v1 and v2.
lerpconst(v1 :
Vect, v2 :
Vect, d :
Number) :
Vect Linearly interpolate between v1 towards v2 by distance d.
slerp(v1 :
Vect, v2 :
Vect, t :
Number) :
Vect Spherical linearly interpolate between v1 and v2.
slerpconst(v1 :
Vect, v2 :
Vect, a :
Number) :
Vect Spherical linearly interpolate between v1 towards v2 by no more than angle a radians
Instance methods
Check if two vectors are equal.
(Be careful when comparing floating point numbers!)
Clamp the vector to length len.
closest_point_on_segment(a : Vect, b : Vect) : Vect
Returns the closest point on the line segment a b, to the point stored in this Vect.
2D vector cross product analog.
The cross product of 2D vectors results in a 3D vector with only a z component.
This function returns the magnitude of the z value.
Returns the distance between this vector and v2.
Returns the squared distance between this vector and v2.
Faster than dist when you only need to compare distances.
length
Returns the length of the vector.
lengthsq
Returns the squared length of the vector.
Faster than length when you only need to compare lengths.
Returns true if the distance between this vector and v2 is less than dist.
normalize
Returns a normalized copy of the vector (unit vector).
perp
Returns a perpendicular vector. (90 degree rotation)
project(v2 : Vect) : Vect
Returns the vector projection of the vector onto v2.
rotate(v2 : Vect) : Vect
Uses complex number multiplication to rotate the vector by v2.
Scaling will occur if the vector is not a unit vector.
rperp
Returns a perpendicular vector. (-90 degree rotation)
to_angle
Returns the angular direction the vector is pointing in (in radians).
unrotate(v2 : Vect) : Vect
