Example PatrolExample.cs

Simple patrol behavior.

This will set the destination on the agent so that it moves through the sequence of objects in the targets array.

using UnityEngine;
using System.Collections;
using Pathfinding;

public class PatrolExample : MonoBehaviour {
public Transform[] targets;

int index;

IAstarAI agent;

void Awake () {
agent = GetComponent<IAstarAI>();
}

void Update () {
if (targets.Length == 0) return;

bool search = false;

// Check if the agent has reached the current target.
// We must check for 'pathPending' because otherwise we might
// detect that the agent has reached the *previous* target
// because the new path has not been calculated yet.
if (agent.reachedEndOfPath && !agent.pathPending) {
index = index + 1;
search = true;
}

// Wrap around to the start of the targets array if we have reached the end of it
index = index % targets.Length;
agent.destination = targets[index].position;

// Immediately calculate a path to the target.
// Note that this needs to be done after setting the destination.
if (search) agent.SearchPath();
}
}
