NAME

Box2D::b2Transform - Contains translation and rotation.

SYNOPSIS

my $transform = Box2D::b2Transform->new( $postiion, $rotation );

DESCRIPTION

A transform contains translation and rotation. It is used to represent the position and orientation of rigid frames.

METHODS

new( $position, $R )

Initialize using a position vector and a rotation matrix.

Parameters:

  • Box2D::b2Vec2 $position

  • Box2D::b2Mat22 $R

Returns a Box2D::b2Transform

GetAngle()

Calculate the angle that the rotation matrix represents.

Returns a float32

Set( $p, $angle )

Set this based on the position and angle.

Parameters:

  • Box2D::b2Vec2 $p

  • float32 $angle

SetIdentity()

Set this to the identity transform.

position()

position( $position )

Parameters:

  • Box2D::b2Vec2 $position (optional)

Returns a Box2D::b2Vec2

R()

R( $rotation )

Parameters:

  • Box2D::b2Mat22 $rotation (optional) - rotation matrix

Returns a Box2D::b2Mat22
