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 43 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 29 of file collisionLevelStateBase.I.

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 168 of file collisionLevelStateBase.I.

◆ 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 121 of file collisionLevelStateBase.I.

◆ get_node_path()

NodePath CollisionLevelStateBase::get_node_path ( ) const

inline

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

Definition at line 66 of file collisionLevelStateBase.I.

References WorkingNodePath::get_node_path.

◆ 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 139 of file collisionLevelStateBase.I.

◆ node()

PandaNode * CollisionLevelStateBase::node ( ) const

inline

Returns the PandaNode pointer of the node we have traversed to.

Definition at line 74 of file collisionLevelStateBase.I.

References WorkingNodePath::node().

◆ 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 49 of file collisionLevelStateBase.cxx.

◆ reserve()

void CollisionLevelStateBase::reserve ( int num_colliders )

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

Definition at line 39 of file collisionLevelStateBase.cxx.

◆ 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.
