clear() → void
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
query() → Iterable<CollisionProspect<ShapeHitbox>>: Returns the potential hitbox collisions
override
remove(ShapeHitbox item) → void: Removes an item from the broadphase. Should be called in a CollisionDetection class while removing a hitbox from its collision detection system.
