Newbie question… I tried few ways and looks like I did not manage it to work…
Lets say I need Add my objects to an array and wan t manipulate them straight from array. (and not to fetch them temporary to Spatial variable…)

Var my_array:Spatial = # no…?
Var my_array= :Spatial # no…?
Var my_array= [:Spatial] # no…?
Var my_array= as Spatial #???..not tested…

Or is it even possible

Type hints can’t be used with arrays. The Array container in Godot is a variant container. If you have a particular need for a single-typed array, there are the Pool*Array types.

You can still add Spatial objects to your array, you just can’t specify that the array will only hold Spatials.

Pool array classes:

var my_generic_array: Array
var my_byte_array: PoolByteArray
var my_color_array: PoolColorArray
var my_int_array: PoolIntArray
var my_float_array: PoolRealArray
var my_string_array: PoolStringArray
var my_vector2_array: PoolVector2Array
var my_vector3_array: PoolVector3Array

All classes — Godot Engine (stable) documentation in English

If anyone’s interested, there’s a proposal to support statically typed arrays for Godot 4.0:
Add static type hints for array members · Issue #192 · godotengine/godot-proposals · GitHub

A note for anyone finding this now, GDScript 2.0 (in Godot 4.x) now supports typed arrays in the current alphas!


var my_array: Array[int] = [1, 2, 3]

tested with Godot 4.0 beta 2 – Works.

Thank you, this is what I was looking for. Godot 4.0.2 Stable.
