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( $groupIndex )
Collision groups allow a certain group of objects to never collide (negative) or always collide (positive). Zero means no collision group. Non-zero group filtering always wins against the mask bits.
Parameters:
int16$groupIndex(optional)
Returns a int16
maskBits()
maskBits( $maskBits )
The collision mask bits. This states the categories that this shape would accept for collision.
Parameters:
uint16$maskBits(optional)
Returns a uint16
