Когда я пытаюсь очистить/удалить Navmesh через скрипт, я получаю это предупреждение:
не может удалить активы. не является действительным путем.

using UnityEngine;
using UnityEditor;
[CustomEditor(typeof(MazeGenerator))]
public class MazeGeneratorEditor : Editor
{
public override void OnInspectorGUI()
{
DrawDefaultInspector();
MazeGenerator mazeGen = (MazeGenerator)target;
if (GUILayout.Button("Generate New Maze"))
{
mazeGen.GenerateAndBuildMaze();
// Mark the scene dirty for editor persistence
if (!Application.isPlaying)
{
EditorUtility.SetDirty(mazeGen);
UnityEditor.SceneManagement.EditorSceneManager.MarkSceneDirty(mazeGen.gameObject.scene);
}
}
if (GUILayout.Button("Clear Maze"))
{
mazeGen.ClearMaze();
if (!Application.isPlaying)
{
EditorUtility.SetDirty(mazeGen);
UnityEditor.SceneManagement.EditorSceneManager.MarkSceneDirty(mazeGen.gameObject.scene);
}
}
}
}

, а затем в моно -скрипте я строю лабиринт и выпекаю поверхность Navmesh, а затем добавил метод Clearmaze, который также удаляет Navmesh: < /p>
