Structs in GDScript

Godot's `Array` type can be used in GDScript to hold typed collections of fields. They’re useful for grouping data together to form records.

This `person` class type has `name` and `age` fields.

```gdscript
class_name Person

var name: String
var age: int

The _init function constructs a new person instance with the given name.

func _init(name: String):
    self.name = name
    self.age = 42

You can create a new instance of a Person.

var p = Person.new("Alice")
print(p.name) # Output: Alice
print(p.age)  # Output: 42

You can name the fields when initializing an instance.

p.name = "Bob"
p.age = 20
print(p) # Output: [Object:Object:1026]

GDScript does not support anonymous structs, but you can use Dictionaries for similar purposes.

var dog = {
    "name": "Rex",
    "is_good": true
}
print(dog) # Output: {name:Rex, is_good:true}

To run this script, attach it to a Node in your Godot project and run the scene.

# Set up a simple scene in Godot
extends Node

func _ready():
    var p = Person.new("Alice")
    print(p.name) # Alice
    print(p.age)  # 42

    p.name = "Bob"
    p.age = 20
    print(p) # Person Object

    var dog = {
        "name": "Rex",
        "is_good": true
    }
    print(dog) # {"name": "Rex", "is_good": true}
