How to package an Unreal Engine Project with Windowed Mode

When you package a UE project without and special settings, it’ll start itself in full screen mode. This can be confusing to users as there’s no obvious way to move the game to a different screen, or to close it when they’re done.

Thankfully there’s a handy blueprint node called Get User Game Settings that lets us override such things and many others. Here’s how to make the game start in a 1280×720 window. Add this into your custom Game Mode’s construction script:

First we get the game settings, then fire off a sequence of three things (just to keep it a little organised):

• set the Full Screen Mode to Windowed
• set the screen resolution
• apply the settings

Make sure to define your custom Game Mode class in both the World Settings as well as Project Settings – Maps and Modes for this to take effect.
