detect visibility change without pause

[Areg]

I want to detect the visibility change in my game ( that is, when , for instance, browser tab loses focus, for example). I know that when that occurs, Phaser automatically pauses my whole game system. I want to prevent that automatic pausing, but still I want to receive signal/event  about this visibility change.

The one part you want is Stage.disableVisibilityChange . By setting this to true the game will not pause.

But by looking in source i can't see if it is possible to launch onBlur and onFocus events with disableVisibilityChange. I may be wrong.

I am listening to game.onPause event. that only works if stage.disablevisibilityChange is false. Other than game.onPause, I do not know about any other event that says that browser lost control that I can listen to

when stage.disbleVisibilityChange is true, onBlur and onFocus events are not being fired, as expected But there has to be some other way to prevent game from auto pausing

If this is a critical production feature you could hack the source a  bit for now until someones points out the correct way to do so.

Look at phaser.js .

Comment out line 20136 and line 20151 ( this.gamePaused(event); and this.gameResumed(event) ; and then go to line

16449, cut the  

 if (this.disableVisibilityChange)    {        return;    }

and paste it above this located at line 16468

  if (document.hidden || document.mozHidden || document.msHidden || document.webkitHidden)    {        this.game.gamePaused(event);    }    else    {        this.game.gameResumed(event);    }

This should fire the onBlur and Onfocus events with disableVisibilityChange=true .

 

Test it and let me know. Keep in mind that this is a BAD approach. You should keep your eyes in this thread for someone with a better solution.

ah, it works. onBlur events are  fired normally and there seems to be no auto pausing , thanks a lot
