JavaScript => public static var AllAreas: int;
C# => public static int AllAreas;

Description 描述

Area mask constant that includes all NavMesh areas.

区域遮挡包含所有的导航网格区域。

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

该遮挡可以被用于在查询功能中，例如NavMesh.Raycast，表明所有导航网格区域类型是可以接受的。

JavaScript:

#pragma strict
// TargetReachable.cs
public class TargetReachable extends MonoBehaviour {
	public var target: Transform;
	private var hit: NavMeshHit;
	private var blocked: boolean = false;
	function Update() {
		// is reachable from the transform location.
		blocked = NavMesh.Raycast(transform.position, target.position, hit, NavMesh.AllAreas);
		Debug.DrawLine(transform.position, target.position, blocked ? Color.red : Color.green);
		if (blocked)
			Debug.DrawRay(hit.position, Vector3.up, Color.red);
	}
}

C#:

// 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);
	}
}
