I’m working on a project using Unreal Engine 5.3 and want to build the game as a borderless window. Is it possible to make this window (not a widget) movable?
Hello there @SPSGamesNord!
Your should be able to set your game as a borderless window by activating the setting in Project Settings > Project Description > Settings > Use Borderless Window
As for the window itself being movable, that is usually tied to Windows OS itself. Once the game is running in Borderless, you should be able to manipulate with keyboard shortcuts (for example, “Control + Shift + Arrow keys” to snap the window, or “Win key + Left/Right Arrow keys” to move the window side to side)
If the native options on WIndows don’t work, the next step would require modifying the system using Windows API and C++, which might be quite a challenge. Alternatively, we can try to enforce it with widgets. You could create a transparent widget and anchor it to the top of the screen, to be used as a drag zone, then bind a mouse input to call a move function.
For further exploration on this path, I would suggest the following thread:
