Forums » Help » Weltmeister file and class name mismatch error

I am receiving the following error when I try to reload Weltimeister:

The following entity classes were not loaded due to file and class name mismatches: lib/game/entities/critter.js (expected name: EntityCritter)

I assume that its a problem with my file or class names. Here are the tops of the files:

critter.js:

ig.module(
	'game.entities.critter'
)
.requires(
	'impact.entity',
	'plugins.box2d.entity'
)
.defines(function(){

ig.EntityCritter = ig.Box2DEntity.extend({

...

player.js

ig.module(
	'game.entities.player'
)
.requires(
	'impact.entity',
   'game.entities.critter'
)
.defines(function(){

EntityPlayer = ig.EntityCritter.extend({
...

and main.js

ig.module( 
	'game.main' 
)
.requires(
	'impact.game',
	'impact.font',
	
	'game.entities.player',
	'game.entities.speck',
   'game.entities.critter',
	'game.levels.thepond',
	
	'plugins.box2d.game',
   'plugins.box2d.debug',
   
   'impact.debug.debug'
)
.defines(function(){

MyGame = ig.Box2DGame.extend({
	

Should be

EntityCritter = ig.Box2DEntity.extend({

not

ig.EntityCritter = ig.Box2DEntity.extend({

Small, but important difference :)

Having made that change it now gives me a slightly different error:

The following entity classes were not loaded due to file and class name mismatches: lib/game/entities/player.js (expected name: EntityPlayer)

Thanks for the help.

Mhh... did you change it to

EntityPlayer = EntityCritter.extend({

instead of

EntityPlayer = ig.EntityCritter.extend({

Also check your browser's error console. Maybe there's more.

Nope. those lines appear correct.
The error console is telling me this: TypeError: ig.EntityCritter is undefined.

I could rar these files and email them to you if that would help.

Please read my previous post again :)

ig.EntityCritter is undefined because you renamed it to the EntityCritter in critter.js. You can&039;t extend #ig.EntityCritter in player.js because it doesn&039;t exist anymore. It's called #EntityCritter now. Remember, you renamed it. Without the ig.

It seems I miss understood your previous post. Thank you. That appears to have fixed my problem.
One other thing, weltmeister is complaining about "this.body" being undefined in my critter.js and speck.js init functions as well as in my critter.js draw function within the ctx.rotate call.
Commenting these out it behaves correctly. I presume this is because weltmeister has no idea what to do with the box2d physics engine?

Yep, you're right about that. Instead of uncommenting, you can use a conditional:

if( !ig.global.wm ) {
    // not in weltmeister
}
