Detailed Description

This holds contact filtering data.

Member Data Documentation

◆ groupIndex

int16 b2Filter::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.

◆ maskBits

uint16 b2Filter::maskBits

The collision mask bits. This states the categories that this shape would accept for collision.
