Box2D: b2FixtureDef Struct Reference

# b2FixtureDef Struct Reference

`#include <b2Fixture.h>`

List of all members.

## Public Member Functions

| b2FixtureDef ()
| The constructor sets the default fixture definition values.
virtual | ~b2FixtureDef ()

## Public Attributes

const b2Shape * | shape
void * | userData
| Use this to store application specific fixture data.
float32 | friction
| The friction coefficient, usually in the range [0,1].
float32 | restitution
| The restitution (elasticity) usually in the range [0,1].
float32 | density
| The density, usually in kg/m^2.
bool | isSensor
b2Filter | filter
| Contact filtering data.

## Detailed Description

A fixture definition is used to create a fixture. This class defines an abstract fixture definition. You can reuse fixture definitions safely.

## Constructor & Destructor Documentation

b2FixtureDef::b2FixtureDef | ( |  | ) | `[inline]`

The constructor sets the default fixture definition values.

virtual b2FixtureDef::~b2FixtureDef | ( |  | ) | `[inline, virtual]`

## Member Data Documentation

float32 b2FixtureDef::density

The density, usually in kg/m^2.

b2Filter b2FixtureDef::filter

Contact filtering data.

float32 b2FixtureDef::friction

The friction coefficient, usually in the range [0,1].

bool b2FixtureDef::isSensor

A sensor shape collects contact information but never generates a collision response.

float32 b2FixtureDef::restitution

The restitution (elasticity) usually in the range [0,1].

const b2Shape* b2FixtureDef::shape

The shape, this must be set. The shape will be cloned, so you can create the shape on the stack.

void* b2FixtureDef::userData

Use this to store application specific fixture data.
