| Method Summary |
| |
__init__(self,
x,
y)
|
| |
__add__(self,
rhs)
Overloads '+' operator. |
| |
__cmp__(self,
otherVector)
Overloads comparison operator. |
| |
__div__(self,
rhs)
Overloads '/' operator. |
| |
__mul__(self,
rhs)
Overloads '*' operator when vector is on left hand side of
operator. |
| |
__rmul__(self,
lhs)
Overloads '*' operator when vector is on right hand side of
operator. |
| |
__str__(self)
Returns string representation of self. |
| |
__sub__(self,
rhs)
Overloads '-' operator. |
| |
distance(self,
otherVector)
Calculates the euclidean distance between two vectors. |
| |
distanceSq(self,
otherVector)
Calculates the euclidean distance squared between two vectors. |
| |
dot(self,
otherVector)
Calculates the dot product. |
| |
getReverse(self)
Returns the vector that is the reverse of this vector. |
| |
length(self)
Returns the length of a 2D vector. |
| |
lengthSq(self)

| |
normalize(self)
Normalizes a 2D Vector. |
| |
perp(self)

| |
reflect(self,
norm)
Given a normalized vector this method reflects the vector it is
operating upon (like the path of a ball bouncing off a wall). |
| |
sign(self,
otherVector)
Returns positive if v2 is clockwise of this vector, minus if
anticlockwise (Y axis pointing down, X axis to right). |
| |
truncate(self,
maxValue)
` Truncates a vector so that its length does not exceed
maxValue. |
| |
zero(self)
Resets vector to zero values. |
| Inherited from Point2D |
| |
decode(self,
data)
Sets self to encoded values. |
| |
encode(self)
Returns encoded description of self. |
