question

Can you check that this is the first line in your main.js:

var game =newPhaser.Game(800,600, Phaser.AUTO,'',{ preload: preload, create: create, update: update });

It sounds like create is being called before game has been defined in your project.

Hey Brendan,

Thanks for response. Yes that Phaser new Game line is at the top of main.js

I've attached a Phaser example of Space Invaders from their samples. It works fine but with the PlayFab plugin add command from the tutorial it fails with "Uncaught TypeError: Cannot set property 'game' of undefined"

Shown below is the bottom of the Phaser Create method where game is already defined and working ok for the rest of the code.

//  And some controls to play the game with
    cursors = game.input.keyboard.createCursorKeys();
    fireButton = game.input.keyboard.addKey(Phaser.Keyboard.SPACEBAR);
    

// Start PlayFab Integration
   game.PlayFab = game.plugins.add(Phaser.Plugin.PlayFab);

Check out the attached files which should run on any web server and show working Space Invaders but PlayFab error for plugin add.

Once working I don't mind cleaning up and simplifying this example game for download with the tutorial to show scores being saved in PlayFab etc.

Cheers

Thanks the updated code in the tutorial is now working ok:

In JavaScript almost everything is an object, null and undefined are exception. When you try to access an undefined variable it always returns undefined and we cannot get or set any property of undefined. In that case, an application will throw Uncaught TypeError cannot set property of undefined.

In most cases, you are missing the initialization . So, you need to initialize the variable first. Moreover, if you are not sure a variable that will always have some value, the best practice is to check the value of variables for null or undefined before using them. If you just want to check whether there's any value, you can do:

if( value ) {

//do something

}

Or, if you do not know whether a variable exists (that means, if it was declared) you should check with the typeof operator .

if ( typeof(some_variable) !== "undefined" && some_variable !== null ) {

//deal with value

}
