Detailed Description

This is the state information the CollisionTraverser retains for each level during traversal.

The CollisionLevelStateBase is the non-template base class. The template version further specifies this on CurrentMask type.

Definition at line 47 of file collisionLevelStateBase.h.

Constructor & Destructor Documentation

◆ CollisionLevelStateBase()

CollisionLevelStateBase::CollisionLevelStateBase ( const CollisionLevelStateBase parent,
PandaNode child 
)
inline

This constructor goes to the next child node in the traversal.

Definition at line 36 of file collisionLevelStateBase.I.

References get_node_path().

Member Function Documentation

◆ get_include_mask()

CollideMask CollisionLevelStateBase::get_include_mask ( ) const
inline

Returns the mask that is applied to the into CollideMask of nodes in the scene graph before testing for bits in common with the from CollideMask of colliders.

See set_include_mask().

Definition at line 210 of file collisionLevelStateBase.I.

Referenced by set_include_mask().

◆ get_local_bound()

const GeometricBoundingVolume * CollisionLevelStateBase::get_local_bound ( int  n) const
inline

Returns the bounding volume of the indicated collider, transformed into the current node's transform space.

Definition at line 149 of file collisionLevelStateBase.I.

References get_parent_bound().

Referenced by CollisionLevelState< MaskType >::any_in_bounds(), CollisionLevelState< MaskType >::apply_transform(), CollisionTraverser::clear_colliders(), and node().

◆ get_node_path()

NodePath CollisionLevelStateBase::get_node_path ( ) const
inline

Returns the NodePath representing the node instance we have traversed to.

Definition at line 80 of file collisionLevelStateBase.I.

References WorkingNodePath::get_node_path(), and node().

Referenced by CollisionTraverser::clear_colliders(), and CollisionLevelStateBase().

◆ get_parent_bound()

const GeometricBoundingVolume * CollisionLevelStateBase::get_parent_bound ( int  n) const
inline

Returns the bounding volume of the indicated collider, transformed into the previous node's transform space, but not transformed by the current node's transform.

This is appropriate for testing against the bounding volume of the current node (which does not have its own transform applied to it).

Definition at line 173 of file collisionLevelStateBase.I.

◆ node()

PandaNode * CollisionLevelStateBase::node ( ) const
inline

◆ prepare_collider()

void CollisionLevelStateBase::prepare_collider ( const ColliderDef def,
const NodePath root 
)

Adds the indicated Collider to the set of Colliders in the current level state.

Definition at line 56 of file collisionLevelStateBase.cxx.

References GeometricBoundingVolume::extend_by(), NodePath::get_parent(), NodePath::get_pos_delta(), NodePath::get_transform(), LMatrix4f::translate_mat(), and LVector3f::zero().

◆ reserve()

void CollisionLevelStateBase::reserve ( int  num_colliders)

Indicates an intention to add the indicated number of colliders to the level state.

Definition at line 44 of file collisionLevelStateBase.cxx.

References prepare_collider().

Referenced by CollisionTraverser::clear_colliders().

◆ set_include_mask()

void CollisionLevelStateBase::set_include_mask ( CollideMask  include_mask)
inline

Specifies the mask that is applied to the into CollideMask of nodes in the scene graph before testing for bits in common with the from CollideMask of colliders.

This is normally all bits on, but you may set it to some other mask to restrict certain bits from consideration.

This is used by the CollisionTraverser to restrict collision with geometry except under the lowest level of LOD.
