Prefab保存

獲取場景中所有的特效，然後檢查所有的ParticleSystem中的Prewarm是否打開，如果打開的話關閉，最後保存Prefab。就是這樣的一個簡單功能。代碼如下：

public static void ModifyParticle()
    {
        ParticleSystem[] ps = FindObjectsOfType<ParticleSystem>();
        Debug.Log(SceneManager.GetActiveScene().name + ":" + ps.Length);
        for (int i = 0; i < ps.Length; i++)
        {
            ParticleSystem p = ps[i];
            if (null != p && p.main.prewarm)
            {
                Debug.Log("Prewarm is true:" + p.name);
                ParticleSystem.MainModule module = p.main;
                module.prewarm = false;
                var status = PrefabUtility.GetPrefabInstanceStatus(p);
                if (status == PrefabInstanceStatus.Connected)
                {
                    PrefabUtility.ApplyPrefabInstance(p.gameObject, InteractionMode.AutomatedAction);
                }
                else if (status == PrefabInstanceStatus.NotAPrefab)
                {
                    var prefabStage = UnityEditor.Experimental.SceneManagement.PrefabStageUtility.GetCurrentPrefabStage();
                    if (null != prefabStage)
                    {
                        PrefabUtility.SaveAsPrefabAsset(p.gameObject, prefabStage.prefabAssetPath);
                    }
                    else
                    {
                        PrefabUtility.SavePrefabAsset(p.gameObject);
                    }
                }
                else
                {
                    Debug.LogError("prefab save failed : " + p.name);
                }
            }
            else
            {
                Debug.Log("Prewarm is false:" + p.name);
            }
        }
    }
