パラメーター

戻り値

GameObject[] The root GameObjects for all instances of the Prefab asset with root prefabRoot.

説明

Retrieves the root GameObjects for all instances of the Prefab asset with root prefabRoot found in all currently loaded scenes. If prefabRoot is not a valid Prefab asset root GameObject, an ArgumentException is thrown.

FindAllInstancesOfPrefab will not return nested Prefab instances.

using UnityEngine;
using UnityEngine.SceneManagement;
using NUnit.Framework;

public class Example : MonoBehaviour
{
    public GameObject prefabAssetRoot;
    private void Start()
    {
        var expectedInstance = (GameObject)PrefabUtility.InstantiatePrefab(prefabAssetRoot);
        var instances = PrefabUtility.FindAllInstancesOfPrefab(prefabAssetRoot);
        Assert.AreEqual(1, instances.Length);
        Assert.AreEqual(expectedInstance, instances[0]);
    }
}

説明

Returns the root GameObjects for all instances of the Prefab asset with root prefabRoot found in scene. If prefabRoot is not a valid Prefab asset root GameObject, or scene is not valid and loaded, ArgumentException is thrown.

FindAllInstancesOfPrefab will not return nested Prefab instances.

using UnityEditor;
using UnityEngine;
using UnityEngine.SceneManagement;
using NUnit.Framework;

public class Example : MonoBehaviour
{
    public GameObject prefabAssetRoot;
    private void Start()
    {
        var expectedInstance = (GameObject)PrefabUtility.InstantiatePrefab(prefabAssetRoot);
        var instances = PrefabUtility.FindAllInstancesOfPrefab(prefabAssetRoot, SceneManager.GetActiveScene());
        Assert.AreEqual(1, instances.Length);
        Assert.AreEqual(expectedInstance, instances[0]);
