Classes in Verse

In Verse, a class is a template for creating objects with similar behaviors and properties. It is a composite type, which means that it’s bundled data of other types and functions that can operate on that data.

Classes are hierarchical, which means that a class can inherit information from its parent (superclass) and share its information with its children (subclasses). Classes can be a custom type defined by the user. Compare to instance.

For example, let’s say you want to have multiple cats in your game. A cat has a name and an age, and they can meow. Your cat class could look like this:

|  |  |
| --- | --- |
|  | cat := class: |
|  | Name : string |
|  | var Age : int = 0 |
|  | Sound : string |
|  |  |
|  | Meow() : void = DisplayMessage(Sound) |

cat := class: Name : string var Age : int = 0 Sound : string Meow() : void = DisplayMessage(Sound)

Definitions of variables that are nested inside the class define fields of the class. Functions defined inside a class may also be called methods. Fields and methods are referred to as class members. In the above example, Sound is a field, and Meow is a method of cat.
