Structured language

Structured language

    • complex programming logic, subroutines, event tracking, and message passing among objects and elements.
    Performance Tuning and Playback Features
    • Synchronization is difficult
    • Authoring system should facilitate precise timing of events.
    • It should enable developers to build a part of a project and then test it immediately.
    Delivery, Cross-Platform, and Internet Playability Features
    • Delivering the project may require building a run-time version of the project, using the multimedia authoring software.
    • Run-time version or standalone
    • allows a project to play back without the complete authoring software and all its tools and editors.
    • Across platforms
    • Authoring systems provide a means for converting their output to be delivered within the context of HTML or DHTML.
    Card- and Page-Based Tools
    • Card- and page-based authoring systems
    • provide a simple and easily understood metaphor for organizing multimedia elements.
    • contains media objects such as buttons, text fields, and graphic objects.
    • provides a facility for linking objects to pages or cards.
    • Card-and page-based systems typically provided two separate layers on each card
    • a background layer that could be shared among many cards
    • a foreground layer that was specific to a single card.
    Icon-Based, Event-Driven Tools
    • Icon-based, event-driven tools provide a visual programming approach to organize and present multimedia.
    • Multimedia elements and interaction cues are organized as objects in a flowchart.
    • Flowchart can be built by dragging appropriate icons from a library, and then adding the content.
    Time-Based Tools
    • Time-based tools are best suited for messages with a beginning and an end.
    • Some time-based tools facilitate navigation and interactive control.
    • Macromedia’s Director and Flash are time-based development environments
    Flash
    Adobe Flash
    • delivering rich multimedia content to the Web.
    • the creation of simple static HTML pages with the Flash Player plug-in.
    • ActionScript
    • based upon the international ECMAScript standard (http://www.ecma-international.org) derived from Netscape's original JavaScript.
