Function Value

Function values are specific values which form the general properties of any construction with a specific function. A function has many function values, and any construction of that function also has those function values.

Function values can be changed for an individual construction, or for a function, which in turn would affect all constructions of that function.

Category values

Some function values are construction-related, and some function values are category-related. The difference between them is only applicable if a single function consists of multiple function categories. For example, the function value indicating the maximum amount of floors for the construction is related to the construction as a whole. However, if the function contains both social housing and luxury housing, the individual types of housing can have different unit sizes configured, as one type of housing may offer bigger housing units than the other.

Overview of all function values

Most function values have specific effects in the context of the Tygron Platform. Individual function values can be grouped into categories based on their effects or themes.

Attributes

Besides the function values which are provided by default, it is possible to add user-defined attributes to function values as well. Any attribute added is automatically available as an attribute for all functions, and all constructions, although the default value of the attribute will be 0.

User-defined attributes added to a function value always apply to the construction as a whole, and cannot be category-specific.

Function value	Attribute	Unit	Per category	Description
(user defined)	(user defined)	(user defined)		Attributes can be used to assign any additional values or properties to functions and the constructions which derive from them.
