public static int AllAreas;

Description

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
using UnityEngine;
using UnityEngine.AI;

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); } }
