Correctly Destroying Game (Getting Error)

[Kartou]

Hi!

 

I'm having trouble with destroying the game after use. I'm calling game.destroy(), but this does not properly shut down the core game loop, hence crashing in:

c.Game.updatec.RequestAnimationFrame.updateRAFwindow.requestAnimationFrame.forceSetTimeOut._onLoop

with the error:

Uncaught TypeError: Cannot read property 'slowMotion' of null

From the source code it looks like game.destroy() should cancel all further updates etc. Maybe I'm missing something?

I have created an example in the sandbox that displays the error. Please see error in the console after pressing the left arrow:

It looks like the destroy does not properly stop the requestAnimationFrame. Maybe I'm not supposed to call game.destroy() at that time?

1. 1. c.Game.updateLogic	@	phaser.js:34680
      c.Game.update	@	phaser.js:34619
      c.RequestAnimationFrame.updateRAF	@	phaser.js:58258
      window.requestAnimationFrame.forceSetTimeOut._onLoop	@	phaser.js:58242

I have exactly the same problem. Did you find a way to solve it?

 `destroy` has done its job; the problem is that you're still in the middle of `updateLogic`, which can't continue because `game.stage` and other references are now missing.

Try calling `destroy` from a keypress handler instead.

Samme! Thanx a lot for this hint.

I realized that the updateLogic was still running. But I had no clue how to stop or break through it. I thought maybe I have to delete a reference to something or I don't know. But I spent 2 days now looking for a solution. Restructuring code. Finding work arounds etc. And in the End it works by just using a simple (button) click event. This should definitely be more obvious or explained somewhere. It's crucial, isn't it?

Thanks again. So glad.
