Retrieves the angular damping coefficient.

Returns:

The angular damping coefficient associated with this actor.

See also:

setAngularDamping() getLinearDamping()

Returns string name of dynamic type.

Returns:

Class name of most derived type of this object.

Implements PxBase.

Retrieves the force threshold for contact reports.

The contact report threshold is a force threshold. If the force between two actors exceeds this threshold for either of the two actors, a contact report will be generated according to the contact report threshold flags provided by the filter shader/callback. See PxPairFlag.

The threshold used for a collision between a dynamic actor and the static environment is the threshold of the dynamic actor, and all contacts with static actors are summed to find the total normal force.

Default: PX_MAX_F32

Returns:

Force threshold for contact reports.

Returns the wake counter of the actor.

Returns:

Returns whether a given type name matches with the type of this instance.

Reimplemented from PxRigidBody.

References PxRigidBody::isKindOf().

Returns true if this body is sleeping.

When an actor does not move for a period of time, it is no longer simulated in order to save time. This state is called sleeping. However, because the object automatically wakes up when it is either touched by an awake object, or one of its properties is changed by the user, the entire sleep mechanism should be transparent to the user.

In general, a dynamic rigid actor is guaranteed to be awake if at least one of the following holds:

• The wake counter is positive (see setWakeCounter()).
• The linear or angular velocity is non-zero.
• A non-zero force or torque has been applied.

• The wake counter is zero.
• The linear and angular velocity is zero.
• There is no force update pending.

If an actor is asleep after the call to PxScene::fetchResults() returns, it is guaranteed that the pose of the actor was not changed. You can use this information to avoid updating the transforms of associated objects.

Note:

A kinematic actor is asleep unless a target pose has been set (in which case it will stay awake until the end of the next simulation step where no target pose has been set anymore). The wake counter will get set to zero or to the reset value PxSceneDesc::wakeCounterResetValue in the case where a target pose has been set to be consistent with the definitions above.

It is invalid to use this method if the actor has not been added to a scene already.

Returns:

True if the actor is sleeping.

See also:

isSleeping() wakeUp() putToSleep() getSleepThreshold()

Forces the actor to sleep.

The actor will stay asleep during the next simulation step if not touched by another non-sleeping actor.

Note:

Any applied force will be cleared and the velocity and the wake counter of the actor will be set to 0.

It is invalid to use this method if the actor has not been added to a scene already or if PxActorFlag::eDISABLE_SIMULATION is set.

It is invalid to use this method for kinematic actors since the sleep state for kinematics is defined based on whether a target pose has been set (see the comment in isSleeping()).

isSleeping() wakeUp()

Sets the angular damping coefficient.

Zero represents no damping.

The angular damping coefficient must be nonnegative.

Default: 0.05

Parameters:

[in]

angDamp

Angular damping coefficient. Range: [0, PX_MAX_F32)

See also:

getAngularDamping() setLinearDamping()

Sets the force threshold for contact reports.

See getContactReportThreshold().

Parameters:

[in]

threshold

Force threshold for contact reports. Range: [0, PX_MAX_F32)

See also:

getContactReportThreshold PxPairFlag

Moves kinematically controlled dynamic actors through the game world.

You set a dynamic actor to be kinematic using the PxRigidBodyFlag::eKINEMATIC flag with setRigidBodyFlag().

The move command will result in a velocity that will move the body into the desired pose. After the move is carried out during a single time step, the velocity is returned to zero. Thus, you must continuously call this in every time step for kinematic actors so that they move along a path.

This function simply stores the move destination until the next simulation step is processed, so consecutive calls will simply overwrite the stored target variable.

The motion is always fully carried out.

Note:

It is invalid to use this method if the actor has not been added to a scene already or if PxActorFlag::eDISABLE_SIMULATION is set.

Parameters:

[in]

destination

The desired pose for the kinematic actor, in the global frame. Range: rigid body transform.

See also:

getKinematicTarget() PxRigidBodyFlag setRigidBodyFlag()

Sets the linear damping coefficient.

Zero represents no damping. The damping coefficient must be nonnegative.

Default: 0.0

Parameters:

[in]

linDamp

Linear damping coefficient. Range: [0, PX_MAX_F32)

See also:

getLinearDamping() setAngularDamping()

Lets you set the maximum angular velocity permitted for this actor.

For various internal computations, very quickly rotating actors introduce error into the simulation, which leads to undesired results.

With this function, you can set the maximum angular velocity permitted for this rigid body. Higher angular velocities are clamped to this value.

Note: The angular velocity is clamped to the set value before the solver, which means that the limit may still be momentarily exceeded.

Default: 7.0

Parameters:

[in]

maxAngVel

Max allowable angular velocity for actor. Range: [0, PX_MAX_F32)

See also:

getMaxAngularVelocity()

Raises or clears a particular rigid dynamic lock flag.

See the list of flags PxRigidDynamicLockFlag

Default: no flags are set

Parameters:

[in]	flag	The PxRigidDynamicLockBody flag to raise(set) or clear. See PxRigidBodyFlag.
[in]	value	The new boolean value for the flag.

See also:

PxRigidDynamicLockFlag getRigidDynamicLockFlags()

Sets the mass-normalized kinetic energy threshold below which an actor may go to sleep.

Actors whose kinetic energy divided by their mass is below this threshold will be candidates for sleeping.

Default: 5e-5f * PxTolerancesScale::speed * PxTolerancesScale::speed

Parameters:

[in]

threshold

Energy below which an actor may go to sleep. Range: [0, PX_MAX_F32)

See also:

isSleeping() getSleepThreshold() wakeUp() putToSleep() PxTolerancesScale

Sets the solver iteration counts for the body.

The solver iteration count determines how accurately joints and contacts are resolved. If you are having trouble with jointed bodies oscillating and behaving erratically, then setting a higher position iteration count may improve their stability.

If intersecting bodies are being depenetrated too violently, increase the number of velocity iterations. More velocity iterations will drive the relative exit velocity of the intersecting objects closer to the correct value given the restitution.

Default: 4 position iterations, 1 velocity iteration

Parameters:

[in]	minPositionIters	Number of position iterations the solver should perform for this body. Range: [1,255]
[in]	minVelocityIters	Number of velocity iterations the solver should perform for this body. Range: [1,255]

See also:

getSolverIterationCounts()

Sets the mass-normalized kinetic energy threshold below which an actor may participate in stabilization.

Actors whose kinetic energy divided by their mass is above this threshold will not participate in stabilization.

This value has no effect if PxSceneFlag::eENABLE_STABILIZATION was not enabled on the PxSceneDesc.

Default: 1e-5f * PxTolerancesScale::speed * PxTolerancesScale::speed

Parameters:

[in]

threshold

Energy below which an actor may participate in stabilization. Range: [0,inf)

See also:

getStabilizationThreshold() PxSceneFlag::eENABLE_STABILIZATION

Sets the wake counter for the actor.

The wake counter value determines the minimum amount of time until the body can be put to sleep. Please note that a body will not be put to sleep if the energy is above the specified threshold (see setSleepThreshold()) or if other awake bodies are touching it.

Note:

Passing in a positive value will wake the actor up automatically.

It is invalid to use this method for kinematic actors since the wake counter for kinematics is defined based on whether a target pose has been set (see the comment in isSleeping()).

It is invalid to use this method if PxActorFlag::eDISABLE_SIMULATION is set.

Parameters:

[in]

wakeCounterValue

Wake counter value. Range: [0, PX_MAX_F32)

See also:

isSleeping() getWakeCounter()

Wakes up the actor if it is sleeping.

The actor will get woken up and might cause other touching actors to wake up as well during the next simulation step.

Note:

This will set the wake counter of the actor to the value specified in PxSceneDesc::wakeCounterResetValue.

It is invalid to use this method if the actor has not been added to a scene already or if PxActorFlag::eDISABLE_SIMULATION is set.

It is invalid to use this method for kinematic actors since the sleep state for kinematics is defined based on whether a target pose has been set (see the comment in isSleeping()).
