How do I simple animation/ moving obiect on loading screen?

Well i do some search on forum but i dont find really good examples about animated preload.

Its possible to make something in this case?

You can make your own loader layout, but for the initial splash screen you only have a few options on what type of graphic you can use. Look at the manual section on loader layouts it has the info about the custom load screen options as well. Usually you can pick your own logo, but it is pretty restricted on the types.
