Code example:

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

Test_device := class(creative_device):
    OnBegin<override>()<suspends>:void=
        Widget := texture_block:
            DefaultImage := ProjectName.TextureName
            DefaultDesiredSize := vector2{X := 128.0, Y := 128.0}
