Detailed Description

A body definition holds all the data needed to construct a rigid body. You can safely re-use body definitions. Shapes are added to a body after construction.

Constructor & Destructor Documentation

b2BodyDef::b2BodyDef ( )

inline

This constructor sets the body definition default values.

Member Data Documentation

bool b2BodyDef::active

Does this body start out active?

Definition at line 116 of file b2Body.h.

bool b2BodyDef::allowSleep

Set this flag to false if this body should never fall asleep. Note that this increases CPU usage.

Definition at line 101 of file b2Body.h.

float32 b2BodyDef::angle

The world angle of the body in radians.

Definition at line 81 of file b2Body.h.

float32 b2BodyDef::angularDamping

Angular damping is use to reduce the angular velocity. The damping parameter can be larger than 1.0f but the damping effect becomes sensitive to the time step when the damping parameter is large.

Definition at line 97 of file b2Body.h.

float32 b2BodyDef::angularVelocity

The angular velocity of the body.

Definition at line 87 of file b2Body.h.

bool b2BodyDef::awake

Is this body initially awake or sleeping?

Definition at line 104 of file b2Body.h.

bool b2BodyDef::bullet

Is this a fast moving body that should be prevented from tunneling through other moving bodies? Note that all bodies are prevented from tunneling through kinematic and static bodies. This setting is only considered on dynamic bodies.

Warning

You should use this flag sparingly since it increases processing time.

Definition at line 113 of file b2Body.h.

bool b2BodyDef::fixedRotation

Should this body be prevented from rotating? Useful for characters.

Definition at line 107 of file b2Body.h.

float32 b2BodyDef::gravityScale

Scale the gravity applied to this body.

Definition at line 122 of file b2Body.h.

float32 b2BodyDef::linearDamping

Linear damping is use to reduce the linear velocity. The damping parameter can be larger than 1.0f but the damping effect becomes sensitive to the time step when the damping parameter is large.

Definition at line 92 of file b2Body.h.

b2Vec2 b2BodyDef::linearVelocity

The linear velocity of the body's origin in world co-ordinates.

Definition at line 84 of file b2Body.h.

b2Vec2 b2BodyDef::position

The world position of the body. Avoid creating bodies at the origin since this can lead to many overlapping shapes.

Definition at line 78 of file b2Body.h.

b2BodyType b2BodyDef::type

The body type: static, kinematic, or dynamic. Note: if a dynamic body would have zero mass, the mass is set to one.

Definition at line 74 of file b2Body.h.

void* b2BodyDef::userData

Use this to store application specific body data.

Definition at line 119 of file b2Body.h.
