Entity.FindCreativeObjectsWithTag Fails to Retrieve Anything

[ZeroYaHero]

Summary

Entity.FindCreativeObjectsWithTag fails to retrieve creative_objects even when it should and when creative_device can. This is an issue because there is still a lot of functionality that devices cover that SceneGraph does not offer a replacement for. API where they interact or rely on each other is vital.

What Type of Bug are you experiencing?

Verse

Steps to Reproduce

1. First write a Verse tag definition and build code:

my_creative_object_tag := class(tag){}

2. After building code, apply the tag to a creative_object of your liking (which in a real world scenario you would use creative_object which has Verse API).

3. Then write a Verse authored creative_device which OnBegin retrieves all creative_object’s with said tag:

my_creative_device := class(creative_device):

    OnBegin<override>()<suspends>:void =
        for(Obj:FindCreativeObjectsWithTag(my_creative_object_tag{})):
            Print("Found Creative Object!")

4. Push changes and start the game and for the n objects you applied the tag to, the print statement will execute n times as expected.

5. Reproduce this same workflow/logic but using the SceneGraph toolset.

6. Write a Verse component which awaits a round start with fort_round_manager in order to safe guard failure due to the devices in the level not being initialized simulation start.

my_verse_component := class<final_super><castable>(component):

    OnBeginSimulation<override>():void =
        if(FortRoundManager := Entity.GetFortRoundManager[]):
            FortRoundManager.SubscribeRoundStarted(OnRoundStarted)

    OnRoundStarted():void =
        for(Obj:Entity.FindCreativeObjectsWithTag(my_creative_object_tag{})):
            Print("Found Creative Object!")

7. Create an entity prefab definition
   

   

8. You can add the my_verse_component to the defintion OR you can drag and drop the entity prefab definition into the level to create an entity prefab instance and add the my_verse_component to it. As long as the entity contains the component as seen in the image below.
   

   

9. Finally, push changes, start the game, and you will observe that the SceneGraph-equivalent workflow will not properly print n times for the n objects the tag was applied to.

Expected Result

For the n objects you applied the tag to, the print statement will execute n times as expected.

Observed Result

SceneGraph-equivalent workflow will not properly print n times for the n objects the tag was applied to.
