I want to set one/more entities (or layers) to remain on multiple levels (and destroy them with an action). For instance a menu button that can be shared on all levels (except on the menu screen).
You could use a global property to set a true/false flag to destroy entities on multiple levels. But only after you setup a rule for each of those entities to do so.
@Lucian currently the only way to do this would be to create an object in the editor and then use code to instantiate the object via code manually and keep track of it. This could become a feature in a future release.
