Member Function Documentation

bool PhysxShape::check_overlap_aabb ( const PhysxBounds3 world_bounds) const

Checks whether the shape overlaps a world-space AABB or not.

Definition at line 396 of file physxShape.cxx.

bool PhysxShape::check_overlap_capsule ( const PhysxCapsule world_capsule) const

Checks whether the shape overlaps a world-space capsule or not.

Definition at line 409 of file physxShape.cxx.

bool PhysxShape::check_overlap_obb ( const PhysxBox world_box) const

Checks whether the shape overlaps a world-space OBB or not.

Definition at line 422 of file physxShape.cxx.

bool PhysxShape::check_overlap_sphere ( const PhysxSphere world_sphere) const

Checks whether the shape overlaps a world-space sphere or not.

Definition at line 435 of file physxShape.cxx.

Retrieves the actor which this shape is associated with.

Definition at line 96 of file physxShape.cxx.

bool PhysxShape::get_flag ( const PhysxShapeFlag  flag) const

Returns the specified shape flag.

Definition at line 161 of file physxShape.cxx.

unsigned short PhysxShape::get_group ( ) const

Retrieves the collision group set for this shape.

The collision group is an integer between 0 and 31.

Definition at line 224 of file physxShape.cxx.

Gets 128-bit mask used for collision filtering.

Definition at line 367 of file physxShape.cxx.

Retrieve the transform of the shape in actor space, i.e.

relative to the actor it is owned by.

Definition at line 296 of file physxShape.cxx.

References PhysxManager::nxMat34_to_mat4(), and LMatrix4f::zeros_mat().

Retrieve the position of the shape in actor space, i.e.

relative to the actor it is owned by.

Definition at line 260 of file physxShape.cxx.

References PhysxManager::nxVec3_to_point3(), and LPoint3f::zero().

unsigned short PhysxShape::get_material_index ( ) const

Returns the material index currently assigned to the shape.

Definition at line 310 of file physxShape.cxx.

const char * PhysxShape::get_name ( ) const

Returns the name string.

Definition at line 125 of file physxShape.cxx.

float PhysxShape::get_skin_width ( ) const

Returns the skin width.

Definition at line 189 of file physxShape.cxx.

Returns a world space AABB enclosing this shape.

Definition at line 381 of file physxShape.cxx.

static void PhysxShape::init_type ( ) [inline, static]
void PhysxShape::set_flag ( const PhysxShapeFlag  flag,
bool  value 
)

Sets the specified shape flag.

The shape may be turned into a trigger by setting one or more of the TriggerFlags to true. A trigger shape will not collide with other shapes. Instead, if a shape enters the trigger's volume, a trigger event will be sent. Trigger events can be listened to by DirectObjects. The following trigger events can be sent:

  • physx-trigger-enter
  • physx-trigger-stay
  • physx-trigger-leave

Definition at line 148 of file physxShape.cxx.

void PhysxShape::set_group ( unsigned short  group)

Sets which collision group this shape is part of.

Default group is 0. Maximum possible group is 31. Collision groups are sets of shapes which may or may not be set to collision detect with each other; this can be set using PhysxScene::set_group_collision_flag().

Definition at line 208 of file physxShape.cxx.

Sets 128-bit mask used for collision filtering.

Does NOT wake the associated actor up automatically.

Definition at line 355 of file physxShape.cxx.

void PhysxShape::set_local_mat ( const LMatrix4f mat)

Set the transform of the shape in actor space, i.e.

relative to the actor it is owned by.

Calling this method does NOT wake the associated actor up automatically.

Calling this method does not automatically update the inertia properties of the owning actor (if applicable); use PhysxActor::update_mass_from_shapes() to do this.

Definition at line 282 of file physxShape.cxx.

References PhysxManager::mat4_to_nxMat34().

void PhysxShape::set_local_pos ( const LPoint3f pos)

Set the position of the shape in actor space, i.e.

relative to the actor it is owned by.

Calling this method does NOT wake the associated actor up automatically.

Calling this method does not automatically update the inertia properties of the owning actor (if applicable); use PhysxActor::update_mass_from_shapes() to do this.

Definition at line 246 of file physxShape.cxx.

References PhysxManager::point3_to_nxVec3().

void PhysxShape::set_material ( const PhysxMaterial material)

Assigns a material to the shape.

Definition at line 323 of file physxShape.cxx.

void PhysxShape::set_material_index ( unsigned short  index)

Assigns a material index to the shape.

The material index can be retrieved by calling PhysxMaterial::get_material_index(). If the material index is invalid, it will still be recorded, but the default material (at index 0) will effectively be used for simulation.

Definition at line 341 of file physxShape.cxx.

void PhysxShape::set_name ( const char *  name)

Sets a name string for this object.

The name can be retrieved again with get_name(). This is for debugging and is not used by the physics engine.

Definition at line 111 of file physxShape.cxx.

void PhysxShape::set_skin_width ( float  skinWidth)

Sets the skin width.

The skin width must be non-negative.

Definition at line 175 of file physxShape.cxx.
