Member Function Documentation

◆ do_sync_b2p()

void BulletRigidBodyNode::do_sync_b2p ( )

Assumes the lock(bullet global lock) is held by the caller.

Definition at line 390 of file bulletRigidBodyNode.cxx.

◆ do_sync_p2b()

void BulletRigidBodyNode::do_sync_p2b ( )

Assumes the lock(bullet global lock) is held by the caller.

Definition at line 379 of file bulletRigidBodyNode.cxx.

◆ make_copy()

PandaNode * BulletRigidBodyNode::make_copy ( ) const
virtual

Returns a newly-allocated PandaNode that is a shallow copy of this one.

It will be a different pointer, but its internal data may or may not be shared with that of the original PandaNode. No children will be copied.

Reimplemented from PandaNode.

Definition at line 72 of file bulletRigidBodyNode.cxx.

◆ pick_dirty_flag()

bool BulletRigidBodyNode::pick_dirty_flag ( )

Returns TRUE if the transform of the rigid body has changed at least once since the last call to this method.

Definition at line 702 of file bulletRigidBodyNode.cxx.

◆ register_with_read_factory()

void BulletRigidBodyNode::register_with_read_factory ( )
static

Tells the BamReader how to create objects of type BulletRigidBodyNode.

Definition at line 711 of file bulletRigidBodyNode.cxx.

References BamReader::get_factory(), and Factory< Type >::register_factory().

◆ write_datagram()

void BulletRigidBodyNode::write_datagram ( BamWriter manager,
Datagram dg 
)
virtual

Writes the contents of this object to the datagram for shipping out to a Bam file.

Reimplemented from BulletBodyNode.

Member Data Documentation

◆ get_inertia

LVector3 BulletRigidBodyNode::get_inertia

Returns the inertia of the rigid body.

Inertia is given as a three component vector. A component value of zero means infinite inertia along this direction.

Definition at line 91 of file bulletRigidBodyNode.h.

◆ get_inv_mass

PN_stdfloat BulletRigidBodyNode::get_inv_mass

Returns the inverse mass of a rigid body.

Definition at line 90 of file bulletRigidBodyNode.h.

◆ get_mass

PN_stdfloat BulletRigidBodyNode::get_mass

Returns the total mass of a rigid body.

A value of zero means that the body is staic, i.e. has an infinite mass.

Definition at line 89 of file bulletRigidBodyNode.h.

Referenced by write_datagram().

◆ set_inertia

void BulletRigidBodyNode::set_inertia

Sets the inertia of a rigid body.

Inertia is given as a three-component vector. A component value of zero means infinite inertia along this direction. Setting the intertia will override the value which is automatically calculated from the rigid bodies shape. However, it is possible that automatic calculation of intertia is trigger after calling this method, and thus overwriting the explicitly set value again. This happens when: (a) the mass is set after the inertia. (b) a shape is added or removed from the body. (c) the scale of the body changed.

Definition at line 91 of file bulletRigidBodyNode.h.

◆ set_mass

void BulletRigidBodyNode::set_mass

Sets the mass of a rigid body.

This also modifies the inertia, which is automatically computed from the shape of the body. Setting a value of zero for mass will make the body static. A value of zero can be considered an infinite mass.
