Summary
Reference to device is always invalid. Console logs (e.g., it has been destroyed during gameplay or disposed of by verse or 'Register with Structural Grid' was specified for it in UEFN)

What Type of Bug are you experiencing?
Verse
Steps to Reproduce
- Create these 2 devices in your scene ( quest_device_problematic and some_device_to_reference )
- Create a quest
- Create a task inside of the quest
- Reference the
some_device_to_reference
( See image for an example)
using { /Fortnite.com/Devices }
using { /Fortnite.com/UI }
using { /Verse.org/Simulation }
using { /UnrealEngine.com/Temporary/SpatialMath }
my_quest_task_problematic<public> := class(quest_task_interface_problematic) {
@editable
Device : ?some_device_to_reference = false
Init<override>():void = {
if(Dev := Device?) {
Print("initing device {Dev.SomeIdentifier}")
spawn {
MoveDevice()
}
# Broken as well, will never call the callback
# Dev.OnSomeEvent.Subscribe()
# If Device changes the data won't be reflected here. Is our reference somehow a copy that's no longer valid??
}
}
MoveDevice()<suspends>:void={
loop {
if(Dev := Device?) {
# Throws errors? Device refernce is somehow broken?
Dev.MoveTo(Dev.GetTransform().Translation + vector3{X := 100.0, Y := 0.0, Z := 0.0}, IdentityRotation(), 1.0)
}
Sleep(1.0)
}
}
}
quest_task_interface_problematic<public> := interface {
Init():void
}
quest_problematic := class(quest_interface_problematic) {
@editable
Tasks : []?quest_task_interface_problematic = array{}
Init<override>():void = {
for(Task : Tasks, T := Task?) {
T.Init()
}
}
GetTasks<override>():[]?quest_task_interface_problematic = Tasks
}
quest_interface_problematic<public> := interface {
Init():void
GetTasks():[]?quest_task_interface_problematic
}
quest_device_problematic<public> := class(creative_device) {
@editable
Quests : []?quest_interface_problematic = array{}
OnBegin<override>():void={
for(Quest : Quests, Q := Quest?) {
Q.Init()
}
}
}
some_device_to_reference<public> := class(creative_device) {
@editable
SomeIdentifier<public> : int = 0
}
Expected Result
Device reference should be valid, however, the reference is broken. You’re still able to get data from the device (e.g. the SomeIdentifier) field, but any event signalled by the device will not call the callback.
Observed Result
When trying to move the object this error is logged. Also, any events will not fire.
LogVerse: Warning: Devices_move_to_debug_log: MoveTo error: The object being moved is no longer valid (e.g., it has been destroyed during gameplay or disposed of by verse or ‘Register with Structural Grid’ was specified for it in UEFN)
Note that if I create the reference (see code below) on the quest_device_problematic directly, it works as expected.
