implement 2D vectors

#vector2.py

Module to handle vectors in a 2D space.

vector2.Vector :

Represent a 2D vector. It can be interpreted as a tuple of length 2 like (x, y).

You can declare a vector by passing :

Vector() -> null vector

Vector( (x, y) ) -> vector of coordinates (x, y)

Vector( angle, length ) -> vector of length length pointing towards angle in radians

Vector( angle=a, len=l ) -> same as Vector(a, l)

Vector( coords=t ) -> same as Vector(t)

Vector( x=x, y=y ) -> same as Vector((x, y))

Positional arguments, if they’re given correctly, will override keyword arguments.

The x and y will override coords, wich will override angle and len.

You can add/substact two vectors together, or multiply/divide them by a scalar.

vector.length() -> return the distance from the origin to the extremity of the vector.

You can compare a vector to another or to a number (the length of the vector(s) will be used).

vector.xint() -> return the integer part of the x-coordinate.

vector.yint() -> same, but with the y-coordinate.

vector.as_tuple() -> convert to a tuple.

vector.as_int_tuple() -> shortcut for (vector.xint(), vector.yint()).

vector.is_equal_to(other) -> with the == or the != operators, two vectors will be compared by their length. use is_equal_to to test if they’re exactly the same.
