Detailed Description
template<class MaskType>
class CollisionLevelState< MaskType >
This is the state information the CollisionTraverser retains for each level during traversal.
This is the template class that specifies the CurrentMask type: the type of bitmask that is used to keep track of the set of active colliders for each node.

Constructor & Destructor Documentation
◆ CollisionLevelState()
|
inline |
This constructor goes to the next child node in the traversal.
Definition at line 33 of file collisionLevelState.I.
Member Function Documentation
◆ any_in_bounds()
| bool CollisionLevelState< MaskType >::any_in_bounds | ( | ) |
Checks the bounding volume of the current node against each of our colliders.
Eliminates from the current collider list any that are outside of the bounding volume. Returns true if any colliders remain, false if all of them fall outside this node's bounding volume.
Definition at line 103 of file collisionLevelState.I.
References indent().
◆ apply_transform()
| bool CollisionLevelState< MaskType >::apply_transform | ( | ) |
Applies the inverse transform from the current node, if any, onto all the colliders in the level state.
Returns true if the inverse transform is valid, or false if it is not valid (e.g. the transform has a scale to zero). If the inverse transform is not valid, the caller should not visit this node.
Definition at line 220 of file collisionLevelState.I.
References TransformState::is_identity().
◆ get_max_colliders()
|
inlinestatic |
Returns the maximum number of colliders that may be added to the CollisionLevelStateBase at any one time.
Definition at line 298 of file collisionLevelState.I.
◆ has_collider()
|
inline |
Returns true if the nth collider in the LevelState is still part of the level.
Definition at line 310 of file collisionLevelState.I.
◆ has_max_colliders()
|
inlinestatic |
Returns true if there is any the maximum number of colliders that may be added to the CollisionLevelStateBase at any one time.
Definition at line 286 of file collisionLevelState.I.
◆ prepare_collider()
|
inline |
Adds the indicated Collider to the set of Colliders in the current level state.
Definition at line 84 of file collisionLevelState.I.
