NAME

Math::Shape::Line - a 2d vector-based infinite line

VERSION

version 0.12

METHODS

new

Constructor, requires 4 values: the x,y values for the base and direction vectors.

    my $line = Math::Shape::Line->new(1, 2, 3, 4);

is_equivalent

Boolean method returns 1 if the line is equivalent to another line object. Lines are equivalent when they are parallel and the base vector of one line occurs along the other line. Requires a Math::Shape::Line object as an argument.

    if ($line->is_equivalent($other_line)
    {
        ...
    }

one_one_side

Boolean method that returns 1 if both points of a LineSegment object are on the same side of the line. Requires a Math::Shape::LineSegment object as an argument.

collides

Boolean method that returns 1 if the line collides with another Math::Shape::Vector library object or not or 0 if not. Requires a Math::Shape::Vectorlibrary object as an argument

    my $l1 = Math::Shape::Line(4, 2);
    my $l2 = Math::Shape::Line(4, 2);

    $l1->collides($l2); # 1
