Method Details [hide private]

__init__(self, points=None)
(Constructor)

source code 
Parameters:
  • points (point[]) - the points that make up the polygon
Overrides: Shape.__init__

addPoint(self, p)

source code 

Brief Description

Parameters:
  • p (Point) - the point to add

getPoints(self)

source code 
Returns: Point[]
A copy of the polygon's points

calcCenter(self)

source code 

Recalculates the center of the shape. This center is simply the average of the x and y coordinates of all the points

convex(self)

source code 
Returns: bool
True if the shape is convex

concave(self)

source code 
Returns: bool
True if the shape is convex

adjust(self, x, y, i=-1)

source code 

Brief Description

Parameters:
  • x - Placeholder
  • y - Placeholder
  • i - index of the point to adjust. -1 adjusts the last point
Overrides: Shape.adjust
(inherited documentation)

intersects(self, p)

source code 
Parameters:
  • p - point to test
Returns: bool
True if p intersects the shape, False otherwise
Overrides: Shape.intersects
(inherited documentation)

shift(self, xoffset, yoffset)

source code 

Moves the shape around by x and y

Overrides: Shape.shift
(inherited documentation)

getHandles(self)

source code 
Returns: Point[]
List of points that define the center of handles for resizing the shape
Overrides: Shape.getHandles
(inherited documentation)
