def match?(object)
  object.contents['shape'] == 'polygon'
end

#poly_vec2s(object) ⇒ Object

Note:

this assumes that we want to convert the points into a format of vec2s specifically for a CP::Shape::Poly shape.

A TMX object currently has an array of points in a format list of strings. This will convert the points into list of CP::Vec2 objects which can be used to create the proper CP::Shape::Poly for the Object.
