NAME

Math::Shape::OrientedRectangle - a 2d oriented rectangle

VERSION

version 0.12

METHODS

new

Constructor, requires 5 values: the x,y values for the center and the x,y values for the half_extend vector and a rotation number.

    my $OrientedRectangle = Math::Shape::OrientedRectangle->new(1, 1, 2, 4, 45);
    my $width = $OrientedRectangle->{rotation}; # 45

get_edge

Returns a Math::Shape::LineSegment object for a given edge of the rectangle. Requires a number for the edge of the rectangle to return (0-3).

    my $segment= $oriented_rectangle->get_edge(1);

axis_is_separating

Boolean method that returns 1 if the axis is separating. Requires a Math::Shape::LineSegment object (for the axis) as an argment.

corner

Returns a Math::Shape::Vector object representing a corner of the rectangle. Requires a number between 0-3 for the corner.

    my $corner = $OrientedRectangle->corner(2);

hull

Returns a Math::Shape::Rectangle object representing the hull of the oriented rectangle.

circle_hull

Returns a new Math::Shape::Circle object representing the hull of the oriented rectangle.

collides

Boolean method returns 1 if the OrientedRectangle collides with another Math::Shape::Vector library object, else returns 0. Requires a Math::Shape::Vector library object as an argument.

    if($OrientedRectangle->collides($other_OrientedRectangle))
    {
        ...
    }
