[Error] TypeError: undefined is not an object ...

[Ninjadoodle]

Hi guys

 

Very rarely, I get this error when testing/reloading my game locally?

 

[Error] TypeError: undefined is not an object (evaluating 'game[extend].extend') (anonymous function) (core.js, line 680)

 

Any ideas what could be causing this?

 

Thank you in advance!

What Panda version are you using?

Hi @enpu

 

This has been happening in most of the versions until now, including the latest develop.

I'm not too sure whether it's something i'm doing wrong, or something else.

 

Right now, I'm using a commit that fixes the mobile browser fullscreen.

 

It's really strange as it happens rarely and completely randomly (when reloading/testing the game) as far as I can tell.

 

Thank you!

Hmm just go this error again when refreshing my game ...

 

[Error] TypeError: undefined is not an object (evaluating 'game[extend].extend')

createClass (core.js, line 711)

createScene (core.js, line 721)

(anonymous function) (stage05.js, line 7)

loadModules (core.js, line 424)

body (core.js, line 353)

global code (stage05.js, line 4)

 

not too sure what it means, but I get a white screen and if I reload again, things work normally.

Hmm, can you show or send your stage05.js file?

Hi @enpu

 

Luckily the code is pretty short ... the thing is that it happens randomly (I don't think it's always stage05)

Hmm yes, if you are creating scene outside of your game "main" module, you must require 'engine.scene' module, to be sure it is loaded before your

modules body is run.

 

I know that's a bit confusing, i should fix that so that every game module would require all engine modules..

Hi @enpu

 

Ok I see, I always separate my levels into modules and didn't know about this. I guess if things don't load in the correct order, it would cause a white screen/crash!

 

Thanks heaps for explaining this! I will go and fix my levels now haha (pretty easy fix)!

I just pushed changes to core, so that now every game module requires core module automatically (before it was only the main game module).

So there is no need to require engine modules (like engine.scene) in your game modules anymore (because core module requires them).
