To create a selector, we simply expand upon the functionality that we described in the Node.cs class:
using UnityEngine; using System.Collections; using System.Collections.Generic; public class Selector : Node { /** The child nodes for this selector */ protected List<Node> m_nodes = new List<Node>(); /** The constructor requires a lsit of child nodes to be * passed in*/ public Selector(List<Node> nodes) { m_nodes = nodes; } /* If any of the children reports a success, the selector will * immediately report a success upwards. If all children fail, * it will report a failure instead.*/ public override NodeStates Evaluate() { foreach (Node node in m_nodes) { switch (node.Evaluate()) { case NodeStates.FAILURE: continue; ...
