Property Elements are a subgroup of the elements in the [[:Category: Oblivion XML|Oblivion XML]] schema, always found as children of [[Menu Element]]s. | Property Elements are a subgroup of the elements in the [[:Category: Oblivion XML|Oblivion XML]] schema, always found as children of [[Menu Element]]s. They define the properties of their parent element - position on the screen, color, texture, etc. In this sense they are similar to traditional xml [[traits]]. | ||
There are two basic data types for properties - numeric and string. A number of Oblivion-specific XML entities are defined for commonly used constants of both types. Particularly useful are the numeric entities "&true;" (numeric value 2) and "&false;" (1), used to with boolean properties like Visible or Targetable. | There are two basic data types for properties - numeric and string.

Property elements may contain literal values, or a set of [[Operator Element]]s | Property elements may contain literal values, or a "formula" expressed as a set of [[Operator Element]]s (but not both). The Oblivion parser evaluates each property element every frame to obtain the ''value'' of the property (see the operator element page for a description on how they are evaluated). If a menu element contains more than one property element of the same type, the last one defined will take precedence. If it contains no property elements for an applicable property, the default value is used (usually zero or the empty string). | ||
