Hi everyone,

I don’t know how to set a minimum of a window. In other words, I don’t know how to denegate for the user to minimize the game. Some function with blueprints?

Thanks everyone.

If you mean that you want to disable the user from minimizing on the packaged product there is a switch (check box) in the project settings.

Go to the main menu of the editor and select “edit”, then “project settings”. Once there select “description”. Next scroll down to the part called “settings”. The second to bottom check mark is labeled “Minimize”.

BTW, there are also check boxes for “Maximize” and “Close” if you need them.

Okey, thanks!

And If I want my game only can play in fullscreen mode, how can I do that?

theres a minimize checkbox under Project Settings, Description, Settings, unticking it removes the minimize option from the packaged window. same panel has maximize and close toggles.

that stops the button but a visitor can still lose focus to another app. Kiosk Lockdown Toolkit is a kiosk mode plugin for Unreal Engine 5 with an always on top mode and a Focus Guard that takes the foreground back when something steals it: [Kiosk Lockdown Toolkit — Block Alt+Tab, Win Key & Taskbar for Kiosks | Fab](https://www.fab.com/listings/c91c6583-6eea-412b-ae64-248ddd69f731)

combine that with the keyboard lockdown and theres no casual path off the game window left.
