NavMesh.AllAreas

Descripción

Area mask constant that includes all NavMesh areas.

The mask can be used in query functions, such as NavMesh.Raycast, to indicate that all NavMesh area types are accepted.

// TargetReachable.cs
using UnityEngine;
using System.Collections;
public class TargetReachable : MonoBehaviour {
	public Transform target;
	private NavMeshHit hit;
	private bool blocked = false;
	void Update() {
		// Allow pass through all area types when testing if the target position
		// is reachable from the transform location.
		blocked = NavMesh.Raycast(transform.position, target.position, out hit, NavMesh.AllAreas);
		Debug.DrawLine(transform.position, target.position, blocked ? Color.red : Color.green);
		if (blocked)
			Debug.DrawRay(hit.position, Vector3.up, Color.red);
	}
}
