Abstract: Systems and methods create and use electronic content that provides objects with capabilities extended beyond those provided by traditional infrastructures. For example, if a tag-based infrastructure does not allow creating an object prior to the object being displayed, a content creator or other user may be able to define or customize a new object using script so that the new object can be created prior to being displayed. The new object may be implemented to take advantage of or otherwise use features of the tag-based infrastructure so that the new object otherwise behaves according to that infrastructure. Certain embodiments facilitate the use of objects prior to their display in environments where such use has previously been restricted or difficult. Generally, a content creation application can provide a content creator greater freedom to create, use, and parameterize objects, and/or in defining object interrelationships.

Abstract: Systems and methods that provide electronic content that requires that the playing computing device download a shared library. Created electronic content can be combined into a package that includes logic to download the shared library, a piece of loading content, and the created electronic content. When the package is used on a computing device, the preloader downloads the shared library, the loading content plays while the shared library downloads, and the created electronic content plays after the shared library has finished downloading.
