How to properly refresh a widget's text value through Verse?

[Leden]

Hello, to make it easy for you I am trying to make some sort of altitude meter and display it on every player’s screens through Verse. The widget should refresh every 0.1s to display new value.

The issue I am facing is that the UI is correctly displayed to players, the value displayed is the right one for each player, but the widget is not removed (after every refresh, a new instance of the widget is created and it stacks onto the previous one).

I do think that the issue is coming from the WidgetText widget textblock that I made, I used the DefaultText Data instead of the .SetText() function but I am unable to use it because of the “transacts” effect.

If anyone can help me on this one it would be much appreciated !

Here is the full code:

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

Nope, I was doing it the right way but with some errors in my code. Someone from the UEFN Discord helped me and provided me with a code snippet which is working! Thank you though

I just searched for “UEFN discord” on google and found the official server which is Fortnite Creative & UEFN Official
