Member Function Documentation

virtual PxRigidDynamic* PxController::getActor (  )  const [pure virtual]

Get the rigid body actor associated with this controller (see PhysX documentation). The behavior upon manually altering this actor is undefined, you should primarily use it for reading const properties.

Returns:
the actor associated with the controller.

virtual PxF32 PxController::getContactOffset (  )  const [pure virtual]

Retrieve the contact offset.

Returns:
The contact offset for the controller.
See also:
PxControllerDesc.contactOffset

virtual PxExtendedVec3 PxController::getFootPosition (  )  const [pure virtual]

Retrieve the "foot" position of the controller, i.e. the position of the bottom of the CCT's shape.

Note:
The foot position takes the contact offset into account
Returns:
The controller's foot position
See also:
PxControllerDesc.position setPosition() getPosition() setFootPosition() move()

virtual PxControllerNonWalkableMode::Enum PxController::getNonWalkableMode (  )  const [pure virtual]

Retrieves the non-walkable mode for the CCT.

Returns:
The current non-walkable mode.
See also:
PxControllerNonWalkableMode

virtual const PxExtendedVec3& PxController::getPosition (  )  const [pure virtual]

Retrieve the raw position of the controller.

The position retrieved by this function is the center of the collision shape. To retrieve the bottom position of the shape, a.k.a. the foot position, use the getFootPosition() function.

The position is updated by calls to move(). Calling this method without calling move() will return the last position or the initial position of the controller.

Returns:
The controller's center position
See also:
PxControllerDesc.position setPosition() getFootPosition() setFootPosition() move()

virtual PxScene* PxController::getScene (  )  [pure virtual]

Retrieve the scene associated with the controller.

Returns:
The physics scene

virtual PxF32 PxController::getSlopeLimit (  )  const [pure virtual]

Retrieve the slope limit.

Returns:
The slope limit for the controller.
See also:
PxControllerDesc.slopeLimit

virtual void PxController::getState ( PxControllerState state  )  const [pure virtual]

Returns information about the controller's internal state.

Parameters:
[out] state The controller's internal state
See also:
PxControllerState

virtual void PxController::getStats ( PxControllerStats stats  )  const [pure virtual]

Returns the controller's internal statistics.

Parameters:
[out] stats The controller's internal statistics
See also:
PxControllerStats

virtual PxF32 PxController::getStepOffset (  )  const [pure virtual]

Retrieve the step height.

Returns:
The step offset for the controller.
See also:
setStepOffset()

virtual PxControllerShapeType::Enum PxController::getType (  )  const [pure virtual]

Return the type of controller.

See also:
PxControllerType

virtual PxVec3 PxController::getUpDirection (  )  const [pure virtual]

Retrieve the 'up' direction.

Returns:
The up direction for the controller.
See also:
PxControllerDesc.upDirection

virtual void* PxController::getUserData (  )  const [pure virtual]

Returns the user data associated with this controller.

Returns:
The user pointer associated with the controller.
See also:
PxControllerDesc.userData

virtual void PxController::invalidateCache (  )  [pure virtual]

Flushes internal geometry cache.

The character controller uses caching in order to speed up collision testing. The cache is automatically flushed when a change to static objects is detected in the scene. For example when a static shape is added, updated, or removed from the scene, the cache is automatically invalidated.

However there may be situations that cannot be automatically detected, and those require manual invalidation of the cache. Currently the user must call this when the filtering behavior changes (the PxControllerFilters parameter of the PxController::move call). While the controller in principle could detect a change in these parameters, it cannot detect a change in the behavior of the filtering function.

See also:
PxController.move

virtual PxControllerCollisionFlags PxController::move ( const PxVec3 disp,
PxF32  minDist,
PxF32  elapsedTime,
const PxControllerFilters filters,
const PxObstacleContext obstacles = NULL 
) [pure virtual]

Moves the character using a "collide-and-slide" algorithm.

Parameters:
[in] disp Displacement vector
[in] minDist The minimum travelled distance to consider. If travelled distance is smaller, the character doesn't move. This is used to stop the recursive motion algorithm when remaining distance to travel is small.
[in] elapsedTime Time elapsed since last call
[in] filters User-defined filters for this move
[in] obstacles Potential additional obstacles the CCT should collide with.
Returns:
Collision flags, collection of PxControllerCollisionFlags

virtual void PxController::release (  )  [pure virtual]

Releases the controller.

virtual void PxController::resize ( PxReal  height  )  [pure virtual]

Resizes the controller.

This function attempts to resize the controller to a given size, while making sure the bottom position of the controller remains constant. In other words the function modifies both the height and the (center) position of the controller. This is a helper function that can be used to implement a 'crouch' functionality for example.

Parameters:
[in] height Desired controller's height

virtual void PxController::setContactOffset ( PxF32  offset  )  [pure virtual]

Sets the contact offset.

Parameters:
[in] offset The contact offset for the controller.
See also:
PxControllerDesc.contactOffset

virtual bool PxController::setFootPosition ( const PxExtendedVec3 position  )  [pure virtual]

Set controller's foot position.

The position controlled by this function is the bottom of the collision shape, a.k.a. the foot position.

Note:
The foot position takes the contact offset into account
Warning:
This is a 'teleport' function, it doesn't check for collisions.
To move the character under normal conditions use the move() function.

Parameters:
[in] position The new (bottom) positon for the controller.
Returns:
Currently always returns true.
See also:
PxControllerDesc.position setPosition() getPosition() getFootPosition() move()

virtual void PxController::setNonWalkableMode ( PxControllerNonWalkableMode::Enum  flag  )  [pure virtual]

Sets the non-walkable mode for the CCT.

Parameters:
[in] flag The new value of the non-walkable mode.
See also:
PxControllerNonWalkableMode

virtual bool PxController::setPosition ( const PxExtendedVec3 position  )  [pure virtual]

Sets controller's position.

The position controlled by this function is the center of the collision shape.

Warning:
This is a 'teleport' function, it doesn't check for collisions.

The character's position must be such that it does not overlap the static geometry.

To move the character under normal conditions use the move() function.

Parameters:
[in] position The new (center) positon for the controller.
Returns:
Currently always returns true.
See also:
PxControllerDesc.position getPosition() getFootPosition() setFootPosition() move()

virtual void PxController::setSlopeLimit ( PxF32  slopeLimit  )  [pure virtual]

Sets the slope limit.

Note:
This feature can not be enabled at runtime, i.e. if the slope limit is zero when creating the CCT (which disables the feature) then changing the slope limit at runtime will not have any effect, and the call will be ignored.
Parameters:
[in] slopeLimit The slope limit for the controller.
See also:
PxControllerDesc.slopeLimit

virtual void PxController::setStepOffset ( const PxF32  offset  )  [pure virtual]

The step height.

Parameters:
[in] offset The new step offset for the controller.
See also:
PxControllerDesc.stepOffset

virtual void PxController::setUpDirection ( const PxVec3 up  )  [pure virtual]

Sets the 'up' direction.

Parameters:
[in] up The up direction for the controller.
See also:
PxControllerDesc.upDirection

virtual void PxController::setUserData ( void *  userData  )  [pure virtual]

Sets the user data associated with this controller.

Parameters:
[in] userData The user pointer associated with the controller.
