unity – Find out how to discover references to a Scriptable Object in all scenes

Unity has an API for checking an asset’s dependencies, however no API that I’m conscious of for locating references (aside from GUI instruments which in my expertise don’t work appropriately in any model of the Unity Editor). To search out references to an asset targetObject, we have now to verify each different asset to see if targetObject is in that asset’s dependencies.

var targetPath = AssetDatabase.GetAssetPath(targetObject);

var assetGUIDs = AssetDatabase.FindAssets("t:Object");
var assetPaths = new Listing();
foreach (var guid in guids) {
    var path = AssetDatabase.GUIDToAssetPath(guid);
    assetPaths.Add(path);
}

var outcomes = new Listing();
foreach (var assetPath in assetPaths) {
    var dependencyPaths = AssetDatabase.GetDependencies(assetPath);
    foreach (var dependencyPath in dependencyPaths) {
        // If the asset we're at the moment  has a dependency on our goal asset,
        // add the asset we're  to the outcomes checklist.
        if (dependencyPath == targetPath) {
            outcomes.add(assetPath);
            break;
        }
    }
}

// Subsequent we might print the matches to the console, or show them in some Editor GUI.
OutputResults(outcomes);

That is extraordinarily sluggish for a big mission. My instance right here shouldn’t be optimized in any respect – you’ll be able to trim down a while by skipping any asset that may’t have a dependency (e.g. AudioClip or Texture2D).

In the event you’re planning to seek for references to a number of totally different belongings back-to-back, it is a good suggestion to cache the entire references you discover to any object in a dictionary – simply keep in mind that the cache could have to be rebuilt when you transfer, take away, or modify something.
