Struct in Verse | Fortnite Documentation | Epic Developer Community

Struct is short for structure, and is a way to group several related variables together. Any variables can be grouped, including variables of different types.

Verse `coordinates := struct: X : float = 0.0 Y : float = 0.0`	Creating a struct: Use the keyword `struct` followed by a code block. Definitions in the struct’s code block define the fields of the struct.
Verse `Position := coordinates{X := 1.0, Y := 1.0}`	Instantiating a struct: You can construct an instance of a struct from an archetype. An archetype defines the values of a struct’s fields.
Verse `Position.X`	Accessing fields on a struct: You can access a struct’s fields to get their value by adding `.` between the struct instance and the field name.

Persistable Type

A struct is persistable when:

Defined with the persistable specifier.
Not parametric.
Only contains members that are also persistable.

When a struct is persistable, it means that you can use them in your module-scoped weak_map variables and have their values persist across game sessions. For more details on persistence in Verse, check out Using Persistable Data in Verse.

You cannot alter a persistable struct once you’ve published your island. For this reason, we recommend using persistable structs only when the schema is known to be constant.

The following is an example of a persistable struct X, Y coordinates that can be stored, updated, and accessed later for a player.

Verse

coordinates := struct<persistable>:
    X:float = 0.0
    Y:float = 0.0

coordinates := struct<persistable>:
    X:float = 0.0
    Y:float = 0.0
