One of Active Worlds main features is the ability to build and manipulate objects to create limitless environments. It has a built-in object manipulation and basic scripting system, which a user can utilize to build preset objects, copy them, specify their exact placement in all three dimensions and write simple scripts to give them a texture, for example.
The scripting system allows objects to be dynamic, and lets users interact with objects in various ways.
For a full list of triggers, types and commands with mini-descriptions, see the object scripting page.
