説明

Utility class for any Prefab related operations.

// This script creates a new menu item Examples>Create Prefab in the main menu.
// Use it to create Prefab(s) from the selected GameObject(s).
// It is placed in the root Assets folder.
using System.IO;
using UnityEngine;
using UnityEditor;

public class Example { // Creates a new menu item 'Examples > Create Prefab' in the main menu. [MenuItem("Examples/Create Prefab")] static void CreatePrefab() { // Keep track of the currently selected GameObject(s) GameObject[] objectArray = Selection.gameObjects;

// Loop through every GameObject in the array above foreach (GameObject gameObject in objectArray) { // Create folder Prefabs and set the path as within the Prefabs folder, // and name it as the GameObject's name with the .Prefab format if (!Directory.Exists("Assets/Prefabs")) AssetDatabase.CreateFolder("Assets", "Prefabs"); string localPath = "Assets/Prefabs/" + gameObject.name + ".prefab";

// Make sure the file name is unique, in case an existing Prefab has the same name. localPath = AssetDatabase.GenerateUniqueAssetPath(localPath);

// Create the new Prefab and log whether Prefab was saved successfully. bool prefabSuccess; PrefabUtility.SaveAsPrefabAssetAndConnect(gameObject, localPath, InteractionMode.UserAction, out prefabSuccess); if (prefabSuccess == true) Debug.Log("Prefab was saved successfully"); else Debug.Log("Prefab failed to save" + prefabSuccess); } }

// Disable the menu item if no selection is in place. [MenuItem("Examples/Create Prefab", true)] static bool ValidateCreatePrefab() { return Selection.activeGameObject != null && !EditorUtility.IsPersistent(Selection.activeGameObject); } }

Static 変数

GetNearestPrefabInstanceRootRetrieves the GameObject that is the root of the nearest Prefab instance the object is part of.
GetObjectOverridesRetrieves a list of objects with information about object overrides on the Prefab instance.
GetOriginalSourceRootWhereGameObjectIsAddedUse this method to find the Prefab Asset root where a Prefab instance or Prefab Asset object was added originally.

GetPrefabInstanceStatusDetermines whether a Prefab instance is properly connected to its asset.
GetPropertyModificationsReturns all modifications that have been applied to a particular Prefab instance in a Scene or modifications for a Prefab instance in an Asset.See SetPropertyModifications for details about the fields of the returned PropertyModification objects.An alternative approach to getting property overrides information for a Prefab instance is to use the GetObjectOverrides API which also has Apply and Revert functionality.When using GetPropertyModifications bear in mind that: it will return both default and non-default overridesIt can return overrides for all child GameObjects and their Componentsit can return overrides that are no longer valid.

IsDefaultOverrideReturns true if the given modification is considered a default override.
IsOutermostPrefabInstanceRootIs the GameObject the root of a Prefab instance, excluding nested Prefabs?

IsPartOfVariantPrefabReturns true if the given object is part of a Prefab Variant Asset or Prefab Variant instance.
IsPrefabAssetMissingReturns true if the given object is part of a Prefab instance but the source asset is missing.
LoadPrefabContentsLoads a Prefab Asset at a given path into an isolated Scene and returns the root GameObject of the Prefab.
