Function

Functions are the blueprints for Buildings in your projects. They describe the purpose and basic properties of Buildings. A Function also references which model sets and colors are used in the 2D and 3D visualization. A Function is effectively a "type of Building".

The properties associated with a Function are known as Function Values

A Building in a Project is always based on one Function. Buildings with the same Function may have different locations, different heights, and different owners. But Buildings with the same Function will have the same set of properties defining their economic, environmental, and spatial effect.

Additionally, Functions can also be used as definitions for actions. When a Function is used as an Action, the Action will be the creation of a new Building, the Function of which is the Function which is used as Action. Some properties of the Function, such as the minimum, maximum, and default amount of floors, also affect how a Stakeholder can enact their action.

The Tygron Platform contains several hundred Functions.

Function values

Main article: Function Value

Functions are composed of a collection of properties called Function Values. These form the actual numeric definitions which are applied on a Building which is set to be of a certain Function. In principle, when such a value of a Building is required for a calculation, the value set in the Function is used.

A complete list of all available Function Values can be found on the Function Values page.

Function Categories

Main article: Category Value

The function selection window. This will appear whenever you need to a select a function.

Functions are divided into Function Categories. Where a Function itself may be "Old Warehouses", such a Function may belong to a Function Category "Industry". This categorization helps when trying to select a specific Function among the full collection of Functions. It also makes it easier to query Buildings in a Project but filtering on the purposes of the Building. Rather than creating individual queries for each Function which matches a broad usage for Buildings, a single query for a Function Category can be used.

Functions are always part of at least one Category, but can also be part of multiple functions. An example is a Function for a Building with shops at a bottom floor, but residences on floors above it. Or flats which contain a mix of both social and luxury housing. In these cases, the Function's Categories each have a respective weight. The Building will be considered wholly of the specified Function, but the Building will be considered "divided up" between the Categories when querying, for example, their floor size.

Function Category:

Currently the Tygron Platform distinguishes the following Categories for Functions:

The table above also indicates which Categories can be combined with others within a Function. To add, remove and change Categories of a Function, see the How-to's section.

Regions

To further help with finding the appropriate Function, they are also divided into regions. Based on the location of the Project, the region for the Project is set automatically. Some Functions are only available in certain regions. This is based on what region of the world the Function would be most appropriate for.

When selecting a Function, it is possible to change the region of the Project to gain access to the Functions of other regions. It is possible to Mix Functions of various regions freely.

Regions:

Currently the Tygron Platform distinguishes the following regions:
