resource loader question regarding middleware

Recommended Posts

Hi guys,

 

Having some trouble trying to use .after() in the loader.  In the following code if I comment out .after()  on('complete') is triggered normally - as are on('load') and on('progress') .  With .after included on('load') and on('progress') fire normally on('complete') fails

	PIXI.loader		.add(assetListA)				.add(assetListB)					.add(assetListC)		.on('load', function(e){			console.log('load')		})		.on('progress', function(loader, resource){			console.log('progress')		})		//.after(function(){console.log('after')})		.on('complete', function(e){ 			console.log('complete')		})		.load() ;

Am I using it wrong?

 

Thanks

Andreas

A middleware function takes two parameters: resource and next.

Your after middleware is called for each resource that is loaded, the resource parameter is that resource that was loaded. Middlewares are asynchronous, the next parameter is a function that you must call when your middleware has completed its work. The reason complete is never called for you is you never call the next() function, so the library can't know when your parser has completed working.

Wow that's pretty comprehensive xerver.  Someone would think you wrote the damn thing ;)

Is next()  a custom function of my own?  If so how do I communicate with the library from within the next function ?  how do I tell it to 'continue'?

I think you misunderstood, your middleware is passed two parameters: the resource that was loaded, and a function to call when you're done.

The library passes you a function to call when you have completed your work, just call it:

	PIXI.loader		.add(assetListA)				.add(assetListB)					.add(assetListC)		.on('load', function(e){			console.log('load')		})		.on('progress', function(loader, resource){			console.log('progress')		})		.after(function(resource, next){console.log('after'); next();})		.on('complete', function(e){ 			console.log('complete')		})		.load() ;
