NAME

Box2D::b2MassData - Holds the mass data computed for a shape.

SYNOPSIS

  my $massData = Box2D::b2MassData->new();
  $shape->ComputeMass( $massData, $density );
  my $mass    = $massData->mass();
  my $center  = $massData->center();
  my $inertia = $massData->I();

DESCRIPTION

This holds the mass data computed for a shape.

METHODS

new()

Default constructor.

center()

center( $center )

  • Box2D::b2Vec2 $center (optional)

Returns a Box2D::b2Vec2

I()

I( $I )

The rotational inertia of the shape about the local origin.

Parameters:

  • float32 $I (optional)

Returns a float32

mass()

mass( $mass )

The mass of the shape, usually in kilograms.

Parameters:

  • float32 $mass (optional)

Returns a float32
