getStiffness

public float getStiffness()

The drive stiffness, i.e. the proportional gain of the implicit PD controller.

See manual for further information, and the drives' implicit spring-damper (i.e. PD control) implementation in particular.

Units: (distance = linear scene units)
Rotational axis: torque/rad if driveType = PxArticulationDriveType::eFORCE; or (rad/s^2)/rad if driveType = PxArticulationDriveType::eACCELERATION
Translational axis: force/distance if driveType = PxArticulationDriveType::eFORCE; or (distance/s^2)/distance if driveType = PxArticulationDriveType::eACCELERATION
Range: [0, PX_MAX_F32]
Default: 0.0f

setStiffness

public void setStiffness(float value)

The drive stiffness, i.e. the proportional gain of the implicit PD controller.

See manual for further information, and the drives' implicit spring-damper (i.e. PD control) implementation in particular.

Units: (distance = linear scene units)
Rotational axis: torque/rad if driveType = PxArticulationDriveType::eFORCE; or (rad/s^2)/rad if driveType = PxArticulationDriveType::eACCELERATION
Translational axis: force/distance if driveType = PxArticulationDriveType::eFORCE; or (distance/s^2)/distance if driveType = PxArticulationDriveType::eACCELERATION
Range: [0, PX_MAX_F32]
Default: 0.0f

getDamping

public float getDamping()

The drive damping, i.e. the derivative gain of the implicit PD controller.

See manual for further information, and the drives' implicit spring-damper (i.e. PD control) implementation in particular.

Units: (distance = linear scene units)
Rotational axis: torque/(rad/s) if driveType = PxArticulationDriveType::eFORCE; or (rad/s^2)/(rad/s) if driveType = PxArticulationDriveType::eACCELERATION
Translational axis: force/(distance/s) if driveType = PxArticulationDriveType::eFORCE; or (distance/s^2)/(distance/s) if driveType = PxArticulationDriveType::eACCELERATION
Range: [0, PX_MAX_F32]
Default: 0.0f

setDamping

public void setDamping(float value)

getMaxForce

@Deprecated
public float getMaxForce()

Deprecated.

Will be removed in a future version The drive force limit.

- The limit is enforced regardless of the drive type #PxArticulationDriveType. - The limit corresponds to a force (linear axis) or torque (rotational axis) if PxArticulationFlag::eDRIVE_LIMITS_ARE_FORCES is set, and to an impulse (force|torque * dt) otherwise.

Range: [0, PX_MAX_F32]
Default: 0.0f

setMaxForce

@Deprecated
public void setMaxForce(float value)

Deprecated.

Will be removed in a future version The drive force limit.

- The limit is enforced regardless of the drive type #PxArticulationDriveType. - The limit corresponds to a force (linear axis) or torque (rotational axis) if PxArticulationFlag::eDRIVE_LIMITS_ARE_FORCES is set, and to an impulse (force|torque * dt) otherwise.

Range: [0, PX_MAX_F32]
Default: 0.0f
