As the topic say, is there a way to tell Unity to start a game Windowed by default ? I disabled the config window and i tried unsetting the option “Is default fullscreen” and i also set the dimension width of 1280 and height of 720 so i expected to have a windows of this size opened at start but it still open it full screen (i am talking about the Windows build not inside the editor).
This should work. But unity automatically saves the settings from the first launch, and then re-uses it for all subsequent launches. So it saved your game being fullscreen - and after changing the default to windowed, it uses the fullscreen save. See http://docs.unity3d.com/ScriptReference/PlayerPrefs.html
Deleting the PlayerPrefs should reset it, and it’ll use default settings on next launch.
Interesting facts! Thanks for this, really appreciated. I didn’t know about first launch settings being saved in the registery. But that make sense cause for controls it was behaving the same way.
