[unity Editor Extension practice] find all prefabs referencing this picture

Last one Unity Editor Extension practice 2 、 Find all prefabrications through code All the prefabricated bodies have been found in .

Then we can use these prefabricated bodies to do some other operations , For example, find the resource reference of the prefabrication . You can traverse the prefabrication directly , Find everything in the prefab Image Components , Then compare Sprite The value of the property , See if it is the same as the detected resources .

Prefabs.Clear();
        if (m_sprite == null) return;

        EditorUtility.DisplayCancelableProgressBar(" Find Atlas ", " Find a graph set ...", 0);
        List<Image> aorImages;

        List<GameObject> _prefabList = GetAllPrefabByAssetDatabase("Assets/Resources/TSUprefabs");
        for (int i = 0; i < _prefabList.Count; i++)
        {
            if (_prefabList[i] == null)
            {
                continue;
            }
            aorImages = new List<Image>(_prefabList[i].GetComponentsInChildren<Image>());
            if (aorImages == null|| aorImages.Count<=0)
            {
                continue;
            }
            foreach (var image in aorImages)
            {
                if (image.sprite==null)
                {
                    continue;
                }
                if (image.sprite.Equals(m_sprite))
                {
                    Prefabs.Add(_prefabList[i]);
                    break;
                }
            }
            bool _cancel = EditorUtility.DisplayCancelableProgressBar(" Find Atlas ", " Find a graph set （"+i+"/"+ (float)_prefabList.Count+"...", i / (float)_prefabList.Count);
            if (_cancel)
            {
                break;
            }
        }
        EditorUtility.ClearProgressBar();

Similarly, you can use this method to replace the picture for the desired preform , Just find the corresponding prefabricated components , Copy picture to Image Components .

To find a reference to an image, use this method , The same is true for other resources .
