Setting full screen in Phaser

[playh5]

Hi!, I'd like to ask why setting full screen in Phaser can only be called using the input from the user 

game.input.onDown.add(gofull, this);function gofull(){	Phaser.StageScaleMode.EXACT_FIT = 0;	game.stage.scale.startFullScreen();	alert('full screen');}

When calling the function gofull() in the create function or update function, the game doesn't go full. Thanks in advance!

It's a browser restriction, otherwise visiting a web site could just instantly make the site go full-screen without you being able to stop it at all. Which is of course a bad thing.

Thanks for the reply Rich, So phaser made html5 game should have a "full screen" button first before loading the entire games. But most html5 games upon opening it would instantly go full screen.

Be sure you understand the difference between true full screen, and just filling the browser window up. They're not the same thing. Going properly full-screen requires user permission / action to happen. Filling the browser doesn't.

Thanks for the clarification Rich. Your explanation helps a lot.

You can use true full screen on browsers, that supports Full Screen API:
