NAME

Box2D::b2Filter - This holds contact filtering data.

SYNOPSIS

  my $filter = Box2D::b2Filter->new();
  $filter->categoryBits( $category_bits );
  $filter->maskBits( $mask_bits );
  $filter->groupIndex($ group_index );

DESCRIPTION

This holds contact filtering data.

METHODS

new()

Default constructor.

Returns a Box2D::b2Filter

categoryBits()

categoryBits( $categoryBits )

The collision category bits. Normally you would just set one bit.

Parameters:

uint16 $categoryBits (optional)

Returns a uint16

groupIndex()

groupIndex( $groupIndex )

Collision groups allow a certain group of objects to never collide (negative) or always collide (positive). Zero means no collision group. Non-zero group filtering always wins against the mask bits.

Parameters:
