    • getPosition

      public PxExtendedVec3 getPosition()
      The position of the character

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

      Default: Zero

    • setPosition

      public void setPosition(PxExtendedVec3 value)
      The position of the character

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

    • getUpDirection

      public PxVec3 getUpDirection()
      Specifies the 'up' direction

      In order to provide stepping functionality the SDK must be informed about the up direction.

      Default: (0, 1, 0)

    • setUpDirection

      public void setUpDirection(PxVec3 value)
      Specifies the 'up' direction

      In order to provide stepping functionality the SDK must be informed about the up direction.

      Default: (0, 1, 0)

    • getSlopeLimit

      public float getSlopeLimit()
      The maximum slope which the character can walk up.

      In general it is desirable to limit where the character can walk, in particular it is unrealistic for the character to be able to climb arbitary slopes.

      The limit is expressed as the cosine of desired limit angle. A value of 0 disables this feature.

      \warning It is currently enabled for static actors only (not for dynamic/kinematic actors), and not supported for spheres or capsules.

      Default: 0.707

    • setSlopeLimit

      public void setSlopeLimit(float value)
      The maximum slope which the character can walk up.

      In general it is desirable to limit where the character can walk, in particular it is unrealistic for the character to be able to climb arbitary slopes.

      The limit is expressed as the cosine of desired limit angle. A value of 0 disables this feature.

      Default: 0.707

    • getInvisibleWallHeight

      public float getInvisibleWallHeight()
      Height of invisible walls created around non-walkable triangles

      The library can automatically create invisible walls around non-walkable triangles defined by the 'slopeLimit' parameter. This defines the height of those walls. If it is 0.0, then no extra triangles are created.

      Default: 0.0

    • setInvisibleWallHeight

      public void setInvisibleWallHeight(float value)
      Height of invisible walls created around non-walkable triangles

      The library can automatically create invisible walls around non-walkable triangles defined by the 'slopeLimit' parameter. This defines the height of those walls. If it is 0.0, then no extra triangles are created.

      Default: 0.0

    • getMaxJumpHeight

      public float getMaxJumpHeight()
      Maximum height a jumping character can reach

      This is only used if invisible walls are created ('invisibleWallHeight' is non zero).

      When a character jumps, the non-walkable triangles he might fly over are not found by the collision queries (since the character's bounding volume does not touch them). Thus those non-walkable triangles do not create invisible walls, and it is possible for a jumping character to land on a non-walkable triangle, while he wouldn't have reached that place by just walking.

      The 'maxJumpHeight' variable is used to extend the size of the collision volume downward. This way, all the non-walkable triangles are properly found by the collision queries and it becomes impossible to 'jump over' invisible walls.

      If the character in your game can not jump, it is safe to use 0.0 here. Otherwise it is best to keep this value as small as possible, since a larger collision volume means more triangles to process.

      Default: 0.0

    • setMaxJumpHeight

      public void setMaxJumpHeight(float value)
      Maximum height a jumping character can reach

      This is only used if invisible walls are created ('invisibleWallHeight' is non zero).

      Default: 0.0

      public float getContactOffset()
      The contact offset used by the controller.

      Specifies a skin around the object within which contacts will be generated. Use it to avoid numerical precision issues.

      This is dependant on the scale of the users world, but should be a small, positive non zero value.

      Default: 0.1

    • setContactOffset

      public void setContactOffset(float value)
      The contact offset used by the controller.

    • getStepOffset

      public float getStepOffset()
      Defines the maximum height of an obstacle which the character can climb.

      A small value will mean that the character gets stuck and cannot walk up stairs etc, a value which is too large will mean that the character can climb over unrealistically high obstacles.

      Default: 0.5

    • setStepOffset

      public void setStepOffset(float value)
      Defines the maximum height of an obstacle which the character can climb.

      Default: 0.5

    • getRegisterDeletionListener

      public boolean getRegisterDeletionListener()
      Use a deletion listener to get informed about released objects and clear internal caches if needed.

      If a character controller registers a deletion listener, it will get informed about released objects. That allows the controller to invalidate cached data that connects to a released object. If a deletion listener is not registered, PxController::invalidateCache has to be called manually after objects have been released.

      Default: true

      Use a deletion listener to get informed about released objects and clear internal caches if needed.

      If a character controller registers a deletion listener, it will get informed about released objects. That allows the controller to invalidate cached data that connects to a released object. If a deletion listener is not registered, PxController::invalidateCache has to be called manually after objects have been released.
