Property Groups

A property group makes the properties it contains show up in a visually separated group in Creation Kit. They have no other purpose.

group SomeGroup {
    auto property PlayerREF: Actor
    auto property Gold001: MiscItem
}

Namespaces

Namespaces can be used to differentiate between different scripts with the same name. In PaperScript, the namespace separator is a double colon (::). You can "import" namespaces to use their members without typing the whole namespace every time.

script SomeNamespace::DemoScript : ScriptObject {}

// ...

import SomeNamespace

DemoScript.SomeMethod()

Structs

A struct is a container of variables that acts like a type.

// Define a struct
struct Point {
    x: Int
    y: Int
}

// Initialize a struct
point1: Point = new Point
point1.x = 1
point1.y = 2

// or you can use the more concise struct initializer
point1: Point = { x: 1, y: 2 }

The `Is` operator

The is operator can be used to check if a variable is of a particular type.

var1: Int = 0
if var1 is Int {
    // true
}

The is operator can be used in Skyrim PaperScript as well! It translates into a cast and a null check internally.

The `var` variable type

var1: Var = 123
