Unity finds resource references

When we want to find the reference of a resource, we can use the tool class at the end of the article

Instructions

1. First put our tool class in the project, it can be placed anywhere.
2. Select the resource to be searched, right-click the selected resource (the resource type is not limited), and select Find Resource Reference in the pop-up options , as shown in Figure 1
3. Select the console output panel and wait for the output result. As shown in Figure 2.

(Picture 1)

(Picture 2)

As can be seen from the output results, Music.prefab and Gamelaungh.prefab reference the music_background.mp3 resource

        {

            return;
        }

        assetPaths = new string[assetGUIDs.Length];

        for (int i = 0; i < assetGUIDs.Length; i++)
        {

                for (int j = 0; j < assetGUIDs.Length; j++)
                {
    
    
                    if (content.IndexOf(assetGUIDs[j]) > 0)

                        log = string.Format("{0} 引用了 {1}", path, assetPaths[j]);
                        logInfo.Add(log);
                    }
                }
            }
        }

        for (int i = 0; i < logInfo.Count; i++)
        {
    
    
            Debug.Log(logInfo[i]);
        }

        Debug.Log("选择对象引用数量：" + logInfo.Count);

        Debug.Log("查找完成");
    }
