def file description

A .def file, or Definition file defines characteristics of an entity. It defines characteristics such as frobability (can player use it, pick it up?), a list of animations, sounds an object makes, and a bounding box for the object among many other options. If an object has a .def file it will need to be created as an entity in the editor, not a model, although its model can still be referenced in the model viewer.

An example of a .def file and its contents

Tags such as this are in .def files that describe a catagory of objects:

"editor_var density"

but are not needed in individual objects .def files,
