ScriptX is a multimedia-oriented development environment created in 1990 by Kaleida Labs. Unlike packages such as Macromedia Director, ScriptX is not an authoring tool for creating multimedia titles, although it does come with a built-in authoring tool. Rather, it is a general-purpose, object-oriented, multiplatform development environment that includes a dynamic language and a class library. ScriptX is as applicable for implementing client–server applications as it is for authoring multimedia titles. ScriptX was designed from the ground up in an integrated fashion, making it smaller, more consistent, and easier to learn than equivalent traditional systems (say, a C++ environment and class library).
ScriptX is part of a complete platform for interactive multimedia. The platform has three major components: the Kaleida Media Player, the ScriptX Language Kit, and application development and authoring tools.
The Kaleida Media Player is the heart of the system. Developers can now create a single application for the Kaleida Media Player instead of targeting specific operating systems like Mac OS and Microsoft Windows.
ScriptX works across multiple hardware platforms and operating systems. Version 1.0 is available for Microsoft's Windows 3.1 and Apple's System 7.
The Kaleida Media Player is used to play back ScriptX titles. The appropriate KMP for Windows or System 7 must be installed on a user's computer to run a ScriptX title.
