TypeError: texture is undefined phaser.js:1717

"Phaser.StateManager - No state found with the key: pmSCENEScene" phaser.js:14293

TypeError: _this.boot is not a function

How can I use this information to fix bugs in my Javascript code? Is there a particular system I should be using for debugging. I am trying to add a sprite to my game and it says 'texture is undefined'. I added a state as shown in the example and then started it and I've followed the code here https://github.com/photonstorm/phaser/wiki/Phaser-General-Documentation-:-States. I don't know where the _this.boot comes from. So please help.

Thanks

game.state.add('pmSCENEScene', game.pmSCENEScene);

try using this:

game.state.add('pmSCENEScene', pmSCENEScene);

this should solve the error "Phaser.StateManager - No state found with the key: pmSCENEScene" phaser.js:14293"

this is because 'game.pmSCENEScene' is not defined. 'pmSCENEScene' defined in the scope of the 'Init' function, but not in the 'game' object.

don't see '_this.boot' either. is this the whole source? try fixing the first error. may be the second will disappear.

I have changed this and I am still having problems

This is what Firefox says in the console:

TypeError: texture is undefined phaser.js:1717

ReferenceError: pmSCENEScene is not defined index.html:30

TypeError: _this.boot is not a function

Thanks

Can you place a 'debugger;' statement before line 30 to see if the pmSCENEScene exists?

hi oliversb,

The easiest way someone can check your code is if you put it up on the web, where it can directly be run.

(Including the assets (or some demo assets) that are loaded.)

Greetings,

JP

Figured out the first problem.

The definition of pmSCENEScene does not work.

You need:

function pmSCENEScene(game) {};

but right now you have:

pmSCENEScene = function(game) { };

(That's just not the way to define a function, or in this case a constructor.)

This does not solve all problems, the game still won't start up.

jpdev · May 11, 2014

woah.. that took me some time..

you forgot the NEW in the first phaser line...

 game = new Phaser.Game(640, 480, Phaser.AUTO, 'game');

oliversb · May 11, 2014

Terribly sorry for the hassle. Thanks a ton. I will sort this out.

jpdev · May 11, 2014

Here is the fixed file.

It still crashes, but only because you powermode object isn't really a sprite.. or something like that.

(Not a state problem anymore )

Fixes: "new", prototype fixes (more then the one posted above)

I have the strong feeling the wiki-tutorial is wrong at that point.

(how the prototype is setup. - From my understanding that's just not how it works.)
