How do i use the Inspector Helper UI for Custom Vector2 Arrays?

Hello Godot Community,

I’m currently working on a project where I would like to create a custom Vector2 array via the Inspector, similar to what’s possible with various built-in polygons like CollisionPolygon and Curve2D. My goal is to use this array to control the movement of a CharacterBody2D object.

Specifically, I’m looking for a way to leverage the familiar helper UI in the 2D editor window to create my own array.
ui

Currently, my code looks like this:

extends CharacterBody2D

@export var walkPath: PackedVector2Array

or alternatively:

@export var walkPath: Curve2D

The issue is that when I use @export Curve2D or PackedVector2Array, I can only add points manually via values, instead of using the convenient UI.

Creating a Path2D using the UI and then manually reading it in the code seems like an inelegant solution. Is there a way to use the Inspector helper UI for my own Vector2 array so that I can conveniently add points via the UI?

I appreciate any help!

Thank you and regards!

As far as I know it’s not available. You’ll need to use a node that supports that or write your own editor plugin Making plugins — Godot Engine (stable) documentation in English and code everything yourself.
