LVector3 BulletRigidBodyNode::get_inertia

(

)

const

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 169 of file bulletRigidBodyNode.cxx.

PN_stdfloat BulletRigidBodyNode::get_mass

(

)

const

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 123 of file bulletRigidBodyNode.cxx.

Referenced by output().

void BulletRigidBodyNode::output

(

ostream &

out

)

const [virtual]

Outputs the Namable.

This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

Reimplemented from BulletBodyNode.

References get_mass().

void BulletRigidBodyNode::set_inertia

(

const LVecBase3 &

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 148 of file bulletRigidBodyNode.cxx.

void BulletRigidBodyNode::set_mass

(

PN_stdfloat

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.

Definition at line 102 of file bulletRigidBodyNode.cxx.

void BulletRigidBodyNode::transform_changed

(

)

[protected, virtual]

Called after the node's transform has been changed for any reason, this just provides a hook so derived classes can do something special in this case.

Reimplemented from PandaNode.
