VinomaGotoOption.SceneTop/ SceneEnd navigates the currently active scene. So sceneName and labelName can be null.
You simply telling it to go to the top of the currently active scene so it will end up again at the Wait action of that scene.
You also do not need to pass a Label if you want to end up at the top/start of the scene.
You probably want this. Don't just copy-paste. Ask if you do not understand what the code means, though it should be clear from my previous post in this thread.
public void ChangeScene(string scene)
VinomaSceneController.Instance.Goto(VinomaGotoOption.Scene, scene, null);
