In libgdx,there is no ParticleEffectLoader for AssetManager.So I write a loader for the particle effect.but the error always occur and says can't load the the file.

Can anybody help me fix the problem or show me a successful particle effect loader?Thanks very much!

my code:

package com.game.data;

import com.badlogic.gdx.assets.AssetDescriptor;
import com.badlogic.gdx.assets.AssetLoaderParameters;
import com.badlogic.gdx.assets.AssetManager;
import com.badlogic.gdx.assets.loaders.AsynchronousAssetLoader;
import com.badlogic.gdx.assets.loaders.FileHandleResolver;
import com.badlogic.gdx.files.FileHandle;
import com.badlogic.gdx.graphics.g2d.ParticleEffect;
import com.badlogic.gdx.utils.Array;

public class ParticleEffectLoader extends 
    AsynchronousAssetLoader<ParticleEffect, AssetLoaderParameters<ParticleEffect>>{

    ParticleEffect particleEffect;

    public ParticleEffectLoader (FileHandleResolver resolver) {
        super(resolver);
        if(particleEffect==null){
            particleEffect=new ParticleEffect();
        }
    }

    @Override
    public void loadAsync(AssetManager manager, String fileName,
            AssetLoaderParameters<ParticleEffect> parameter) {
        System.out.println("loadAsync");
        FileHandle particleFile = resolve(fileName);
        particleEffect.loadEmitters(particleFile);
        particleEffect.loadEmitterImages(imagesDir);
    }

    @Override
    public ParticleEffect loadSync(AssetManager manager, String fileName,
            AssetLoaderParameters<ParticleEffect> parameter) {
        System.out.println("loadSync");
        return particleEffect;
    }

    @Override
    public Array<AssetDescriptor> getDependencies(String fileName,
            AssetLoaderParameters<ParticleEffect> parameter) {
        System.out.println("getDependencies");
//      FileHandle imagesDir = resolve("res/");
//      particleEffect.loadEmitterImages(imagesDir);
        return null;
    }

}

I need to implement a ParticleEffectLoader today too, and glad to find out that it's quite simple. Below is my implementation, I've tested it in my own project, I use SynchronousAssetLoader.

import com.badlogic.gdx.assets.AssetDescriptor;
import com.badlogic.gdx.assets.AssetLoaderParameters;
import com.badlogic.gdx.assets.AssetManager;
import com.badlogic.gdx.assets.loaders.FileHandleResolver;
import com.badlogic.gdx.assets.loaders.SynchronousAssetLoader;
import com.badlogic.gdx.files.FileHandle;
import com.badlogic.gdx.graphics.g2d.ParticleEffect;
import com.badlogic.gdx.utils.Array;

/**

public class ParticleEffectLoader extends SynchronousAssetLoader<ParticleEffect, ParticleEffectLoader.ParticleEffectParameter> {

    public ParticleEffectLoader(FileHandleResolver resolver) {
        super(resolver);
    }

    @Override
    public ParticleEffect load(AssetManager assetManager, String fileName,
            ParticleEffectParameter parameter) {
            ParticleEffect effect = new ParticleEffect();
        FileHandle effectFile = resolve(fileName);
        FileHandle imgDir = effectFile.parent();
        effect.load(effectFile, imgDir);
        return effect;
    }

    @Override
    public Array<AssetDescriptor> getDependencies(String fileName,
            ParticleEffectParameter parameter) {
        return null;
    }

    static public class ParticleEffectParameter extends AssetLoaderParameters<ParticleEffect> {
        public ParticleEffectParameter () {
        }
    }

}

Note that in my project I always put image file in the same folder as the Particle file, so this is enough for me.

Just for the sake of completeness: Meanwhile there is an official ParticleEffectsLoader: http://libgdx.badlogicgames.com/nightlies/docs/api/com/badlogic/gdx/assets/loaders/ParticleEffectLoader.html
