Its anoying that the game always suspends when the player clicks outside the window, or leaves the application. Is there a way to make it so that the game will always run, even if the players isnt using it?
In player settings → Resolution and presentation, check ‘Run in Background’.
What platform is the game running on? I’m assuming android because of the tag.
