@editable Array Picker Missing for vehicle_spawner_device

General Issues and Bug Reporting

1

Summary

In UEFN version 36.30, declaring an @editable array of type vehicle_spawner_device does not display the device picker/dropdown in the Details panel, making it impossible to assign placed vehicle spawner devices to the array. This issue does not affect all device types; for example, arrays of button_device work as expected.

What Type of Bug are you experiencing?

Verse

Steps to Reproduce

Failing Case:

  1. Place one or more vehicle spawner devices in the level (e.g., Sports Car Spawner, Fang Spawner, Big Rig Spawner).

  2. Add the following Verse code to a new device, build, and place it in the world:
    using { /Fortnite.com/Devices }
    using { /Verse.org/Simulation }

    test_vehicle_spawner_array := class(creative_device):
    @editable
    VehicleSpawners : vehicle_spawner_device = array{}

  3. In the Details panel for the Verse device, click “Add Element” under the array field.

  4. Result: No picker or assignable field appears for each array element—only a blank entry with no option to assign the spawner.

Working Comparison:

  1. Place one or more Button Devices in the level.
  2. Add this Verse code to a new Verse device, build, and place it:
    using { /Fortnite.com/Devices }
    using { /Verse.org/Simulation }

test_button_array := class(creative_device):
@editable
Buttons : button_device = array{}

  1. In the Details panel, clicking “Add Element” under the array field displays a picker that allows selection of placed button devices.

Expected Result

For device type vehicle_spawner_device, the picker should appear in the Details panel and be assignable in the array.

Observed Result

Declaring an @editable array of type vehicle_spawner_device does not display the device picker/dropdown in the Details panel of the Verse Device in UEFN.

Hey! This happened for our map too recently.

We worked it out by typing correctly and specifically the device we were using.

For sports cars, whiplash, the solution was using “vehicle_spawner_sports_car_device” instead of “vehicle_spawner_device”.

Hope it helps!

Thank you for this! Had tried doing just the device name and didn’t think of it this way; works out. :slight_smile:

Although this doesn’t seem to work for the Fang Spawners; unless I’m blind and it isn’t actually called a Fang or Nitro_Fang.
