Max number of map{}

General Issues and Bug Reporting

Summary

i use around 500 instances of [player]texture_block = map{}
whenever i load my game the editor will NOT connect to the client
if i remove all the maps it starts working again
Is there a way i can store references to the UI elements so that i can update them depending on game state without using so many instances of map{}?
Is there a memory limit for Verse code that i am hitting? there are no Verse errors or warnings, but every time i hit launch session it loads me into the game, starts the game, and the editor fails to connect to the client, so its basically useless.
I just want to have the UI update and change states based on user interaction and user data. The only way to do that is to load every image i need where i need it, and toggle visibility as needed, but i cant store references to all the UI objects, so im not sure what to do.

500 player texture maps is a lot. it sounds like you’re creating/assigning a new widget for each UI change. There are a lot of built in functions for the texture block like SetImage() or SetDefaultDesiredSize() that let you edit the widget after it is created, you can see the full list here : texture_block class | Unreal Editor for Fortnite Documentation | Epic Developer Community

thank you for this tip, i will use SetImage() instead of toggling visibility on a stack of images

I brought the number of maps{} down to less than 25, reusing them when i close and open different menus, instead of having 500 unique instances, performance is back to normal

i think having 500 instances of [player] map{} was causing some type of overflow or reaching a hard limit that i didnt recieve any warning about, but the result was the editor would not connect to the client.
