Returns the character controller type.

The controllers type.

Member Data Documentation

Specifies a user behavior callback.

This behavior callback is called to customize the controller's behavior w.r.t. touched shapes.

Setting this to NULL disables the callback.

Default: NULL

See also:
PxControllerBehaviorCallback

Referenced by copy(), and PxControllerDesc().

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

Referenced by copy(), isValid(), and PxControllerDesc().

Density of underlying kinematic actor.

The CCT creates a PhysX's kinematic actor under the hood. This controls its density.

Default: 10.0

Referenced by copy(), isValid(), and PxControllerDesc().

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

See also:
upDirection slopeLimit maxJumpHeight

Referenced by copy(), and PxControllerDesc().

The material for the actor associated with the controller.

The controller internally creates a rigid body actor. This parameter specifies the material of the actor.

Default: NULL

See also:
PxMaterial

Referenced by copy(), isValid(), and PxControllerDesc().

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

upDirection slopeLimit invisibleWallHeight

Referenced by copy(), and PxControllerDesc().

The type of the controller. This gets set by the derived class' ctor, the user should not have to change it.

Referenced by isValid().

The non-walkable mode controls if a character controller slides or not on a non-walkable part.

This is only used when slopeLimit is non zero.

Default: PxControllerNonWalkableMode::ePREVENT_CLIMBING

See also:
PxControllerNonWalkableMode

Referenced by copy(), and PxControllerDesc().

The position of the character.

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

Referenced by copy(), and PxControllerDesc().

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.

See also:
PxController::invalidateCache
Default: true

Referenced by copy(), and PxControllerDesc().

Specifies a user report callback.

This report callback is called when the character collides with shapes and other characters.

Setting this to NULL disables the callback.

Default: NULL

See also:
PxUserControllerHitReport

Referenced by copy(), and PxControllerDesc().

Scale coefficient for underlying kinematic actor.

The CCT creates a PhysX's kinematic actor under the hood. This controls its scale factor. This should be a number a bit smaller than 1.0.

Default: 0.8

Referenced by copy(), isValid(), and PxControllerDesc().

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

See also:
upDirection invisibleWallHeight maxJumpHeight

Referenced by copy(), isValid(), and PxControllerDesc().

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

See also:
upDirection

Referenced by copy(), isValid(), PxCapsuleControllerDesc::isValid(), PxBoxControllerDesc::isValid(), and PxControllerDesc().

Specifies the 'up' direction.

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

Default: (0, 1, 0)

Referenced by copy(), and PxControllerDesc().

User specified data associated with the controller.

Default: NULL

Referenced by copy(), and PxControllerDesc().

Cached volume growth.

Amount of space around the controller we cache to improve performance. This is a scale factor that should be higher than 1.0f but not too big, ideally lower than 2.0f.

Default: 1.5

Referenced by copy(), isValid(), and PxControllerDesc().
