Base Type
public PxRigidActor(PxRigidActor)
-
class PxRigidStatic : public PxRigidActor
PxRigidStatic represents a static rigid body simulation object in the physics SDK.
PxRigidStatic objects are static rigid physics entities. They shall be used to define solid objects which are fixed in the world.
Creation
Instances of this class are created by calling PxPhysics::createRigidStatic() and deleted with release().
Visualizations
Global Pose Manipulation
-
virtual PxTransform getGlobalPose() const = 0
Retrieves the actors world space transform.
The getGlobalPose() method retrieves the actor’s current actor space to world space transformation.
Note
It is not allowed to use this method while the simulation is running (except during PxScene::collide(), in PxContactModifyCallback or in contact report callbacks).
- Returns
Global pose of object.
-
virtual void setGlobalPose(const PxTransform &pose, bool autowake = true) = 0
Method for setting an actor’s pose in the world.
This method instantaneously changes the actor space to world space transformation.
This method is mainly for dynamic rigid bodies (see PxRigidDynamic). Calling this method on static actors is likely to result in a performance penalty, since internal optimization structures for static actors may need to be recomputed. In addition, moving static actors will not interact correctly with dynamic actors or joints.
To directly control an actor’s position and have it correctly interact with dynamic bodies and joints, create a dynamic body with the PxRigidBodyFlag::eKINEMATIC flag, then use the setKinematicTarget() commands to define its path.
Even when moving dynamic actors, exercise restraint in making use of this method. Where possible, avoid:
moving actors into other actors, thus causing overlap (an invalid physical state)
moving an actor that is connected by a joint to another away from the other (thus causing joint error)

- Parameters
pose – [in] Transformation from the actors local frame to the global frame. Range: rigid body transform.
autowake – [in] whether to wake the object if it is dynamic. This parameter has no effect for static or kinematic actors. If true and the current wake counter value is smaller than PxSceneDesc::wakeCounterResetValue it will get increased to the reset value.
Shapes
-
virtual bool attachShape(PxShape &shape) = 0
Attach a shape to an actor.
This call will increment the reference count of the shape.
Attaching a triangle mesh, heightfield or plane geometry shape configured as eSIMULATION_SHAPE is not supported for non-kinematic PxRigidDynamic instances.
Sleeping: Does NOT wake the actor up automatically.
Note
Mass properties of dynamic rigid actors will not automatically be recomputed to reflect the new mass distribution implied by the shape. Follow this call with a call to the PhysX extensions method PxRigidBodyExt::updateMassAndInertia() to do that.
- Parameters
shape – [in] the shape to attach.
- Returns
True if success.
-
virtual void detachShape(PxShape &shape, bool wakeOnLostTouch = true) = 0
Detach a shape from an actor.
This will also decrement the reference count of the PxShape, and if the reference count is zero, will cause it to be deleted.
Sleeping: Does NOT wake the actor up automatically.
- Parameters
shape – [in] the shape to detach.
wakeOnLostTouch – [in] Specifies whether touching objects from the previous frame should get woken up in the next frame. Only applies to PxArticulationReducedCoordinate and PxRigidActor types.
-
virtual PxU32 getNbShapes() const = 0
Returns the number of shapes assigned to the actor.
You can use getShapes() to retrieve the shape pointers.
See also
- Returns
Number of shapes associated with this actor.
-
virtual PxU32 getShapes(PxShape **userBuffer, PxU32 bufferSize, PxU32 startIndex = 0) const = 0
Retrieve all the shape pointers belonging to the actor.
These are the shapes used by the actor for collision detection.
You can retrieve the number of shape pointers by calling getNbShapes()
Note: Removing shapes with PxShape::release() will invalidate the pointer of the released shape.
See also
- Parameters
userBuffer – [out] The buffer to store the shape pointers.
bufferSize – [in] Size of provided user buffer.
startIndex – [in] Index of first shape pointer to be retrieved
- Returns
Number of shape pointers written to the buffer.
Constraints
-
virtual PxU32 getNbConstraints() const = 0
Returns the number of constraint shaders attached to the actor.
You can use getConstraints() to retrieve the constraint shader pointers.
See also
- Returns
Number of constraint shaders attached to this actor.
-
virtual PxU32 getConstraints(PxConstraint **userBuffer, PxU32 bufferSize, PxU32 startIndex = 0) const = 0
Retrieve all the constraint shader pointers belonging to the actor.
You can retrieve the number of constraint shader pointers by calling getNbConstraints()
Note: Removing constraint shaders with PxConstraint::release() will invalidate the pointer of the released constraint.
- Parameters
userBuffer – [out] The buffer to store the constraint shader pointers.
bufferSize – [in] Size of provided user buffer.
startIndex – [in] Index of first constraint pointer to be retrieved
- Returns
Number of constraint shader pointers written to the buffer.
Public Functions
-
inline virtual const char *getConcreteTypeName() const
Returns string name of dynamic type.
- Returns
Class name of most derived type of this object.
-
virtual void release() = 0
Deletes the rigid actor object.
Also releases any shapes associated with the actor.
Releasing an actor will affect any objects that are connected to the actor (constraint shaders like joints etc.). Such connected objects will be deleted upon scene deletion, or explicitly by the user by calling release() on these objects. It is recommended to always remove all objects that reference actors before the actors themselves are removed. It is not possible to retrieve list of dead connected objects.
Sleeping: This call will awaken any sleeping actors contacting the deleted actor (directly or indirectly).
Calls PxActor::release() so you might want to check the documentation of that method as well.

-
virtual PxU32 getInternalActorIndex() const = 0
Returns the internal actor index.
Warning
This is only defined for actors that have been added to a scene.
- Returns
The internal actor index, or 0xffffffff if the actor is not part of a scene.

-
virtual void setName(const char *name) = 0
Sets a name string for the object that can be retrieved with getName().
