Hey. I got a serious annoying problem, I startet using unity3d, and it's the best i've tryed untill now, but lets say that i'm making a game, and wanna try the scene by pressing the 'Play' button then it just pauses 1 second after I hit 'play' and I don't even touch the 'Pause' button. I can't even uncheck the 'Pause' button so it would go back to play' only, sometimes I just press 'Play' and then it works fine untill! I press on the screen, then it pauses. And I pretty much can't find a way to fix it.
If you are getting an error or even a warning when the pause is occurring, you may have unity set to pause on errors. If you want to disable this, you can either click the error on the status bar of the editor or click the window menu and select Console from the dropdown. There is a tab in here labelled ‘Error Pause’. If it is highlighted, click it to unhighlight.
I have the same problem, I suggest first rebooting your computer, and if that fails, reimport your assets. The problem with the latter is that it can take an hour or more, depending on the filesize of your project. Another thing you can do is reinstall unity (What worked for me)
Just in case anyone is still having a problem with Unity pausing right after going into Play Mode (I was), a reason this can be happening is that somewhere in the code of the scripts of the project there is a Debug.Break() function being used.
I was using a project from someone else, and Unity kept pausing right after going into Play Mode, I found out that there were a bunch of Debug.Break’s responsible.
(Debug.Break(); will pause the Editor in Play Mode.)
