Lets say I want an options windows that I can trigger from every level. I want to have common actions in one event sheet and use common sprites so I don't have to change it in each and every level. Now creating an event sheet to include isn't a problem. However, I'm not sure about the sprites. Previously I have seen an error message saying a sprite needs to be added to the layout before they can used in the event sheets.
So my question is as followed. Can I just place all my sprites in an unused layout and then use another empty layout with an included event sheet to spawn the sprites I need?
