+# InstanceFinder
+
+There is a lot of useful information you can get from [NetworkBehaviours ](../../fishnet-building-blocks/components/network-behaviour-components/)but there may be some cases that your script does not inherit from NetworkBehaviour. This is where InstanceFinder can help you out.
+
+InstanceFinder provides you quick access to commonly needed references or information. Some examples are: [SceneManager](../../fishnet-building-blocks/components/managers/scenemanager.md), IsClientStarted, [TimeManager](../../fishnet-building-blocks/components/managers/time-manager.md), and [more](https://fish-networking.com/FishNet/api/api/FishNet.InstanceFinder.html#properties).
+
+```csharp
+public class MyButton : MonoBehaviour
+{
+    public Image ButtonImage;
+    
+    /* It wouldn't make sense to update the UI
+    * color on the server since it will have
+    * no graphical interface. To save performance
+    * we're only going to update color if client.
+    * However, since this is a MonoBehaviour class
+    * you do not have access to base.IsClientStarted.
+    * Instead the InstanceFinder may be used. */
+    private void SetColor(Color c)
+    {
+        if (InstanceFinder.IsClientStarted)
+            ButtonImage.color = c;
+    }
+}
+```
