Detailed Description

A class providing a selector composite node for a behavior tree.

A selector node is a composite node that is designed to select and run the first child with a non-zero priority and run it. If the selector node is allowed to preempt, a child that is running may be overridden by an earlier child with a non-zero priority during the update function.

If the selector node is not assigned a priority function, its priority will be assigned as the priority of the running child if this node is currently running, or as the priority of first of its children with a non-zero priority.

A selector node's state is directly based upon the child node currently running or the child node that has finished running. Only one child node will finish running as part of the SelectorNode.

Constructor & Destructor Documentation

cugl::ai::SelectorNode::SelectorNode ( )

inline

Creates an uninitialized selector node.

You should never call this constructor directly. Instead, you should allocate a node with the BehaviorManager instance.

cugl::ai::SelectorNode::~SelectorNode ( )

inline

Deletes this node, disposing all resources.

Member Function Documentation

virtual int cugl::ai::SelectorNode::selectChild ( ) const

overridevirtual

Returns a (possibly new) active child for this node.

This method is subclass dependent, and uses the rules of that subclass to select a child. If no child is selected, this method returns -1.

Returns: a (possibly new) active child for this node.

Implements cugl::ai::CompositeNode.

The documentation for this class was generated from the following file:
