In this tutorial I go over the steps it takes to make a loot box in UEFN with Blender for the custom lootbox and Verse for the mechanics of it.

Hi there, thanks for all the great tutorials you share, however on this particular one… I followed the tutorial and the loot box wont trigger… I am not sure what I have done wrong as I think I have reproduced everything accurately.

here’s the code:

using { /Fortnite.com/Devices }
using { /Verse.org/Simulation }
using { /UnrealEngine.com/Temporary/Diagnostics }
using { /UnrealEngine.com/Temporary/SpatialMath }

GameManager := class(creative_device):
@editable
PS1:player_spawner_device = player_spawner_device{}

@editable
LootBoxButton: button_device = button_device{}

@editable
LootBoxLid: creative_prop = creative_prop{}

@editable
LootGranter: item_granter_device = item_granter_device{}

@editable
VFX: vfx_spawner_device = vfx_spawner_device{}

OnBegin<override>()<suspends>:void=
    
    LootBoxButton.InteractedWithEvent.Subscribe(OnLootBoxButton)
OnLootBoxButton(Agent: agent): void=
    spawn:
        RotateBoxLid(Agent)
RotateBoxLid(Agent: agent)<suspends>:void=
    #disable the button
    LootBoxButton.Disable()
    loop: 
        LidTransform:transform = LootBoxLid.GetTransform()
        Rotation:rotation=LidTransform.Rotation
        LootBoxLid.MoveTo(LidTransform.Translation, Rotation.ApplyLocalRotationY(-1.0), 0.5)
        NewRotation:rotation=LidTransform.Rotation
        YPR:= NewRotation.GetYawPitchRollDegrees()
        if(YPR[0] >= -90.0):
            LootGranter.GrantItem(Agent)
            VFX.Disable()
            break

The LootBox folder contains the following:

  • DeliveryBag (blueprint prop)
    • Button
    • LootBoxLid (blueprint prop)
    • LootGranter
    • VFXSpawner

When I launch the client, everything appears to work, however when I try to interact with the button… nothing happens. The Lid does not rotate open, and the item spawner does not respond.

Any idea where I have gone wrong… your help would be much appreciated.

Quick Update… having defined the editables, I neglected to select them in the device settings.

Problem solved … it all works :slight_smile:
