Can't get particle textures to work

cocos2d-x JavaScript
#1

Every time I try to use a texture in a CCParticleSystem, I just get blurred circles. I’ve tried it using textures embedded in plists, texture files referenced from plists, and by using the particle systems in CCParticleExamples.js.

        var particle=cc.ParticleFlower.create();
        particle.setPosition(this.getContentSize().width/2, this.getContentSize().height/2);
        this.addChild(particle);
        particle.setTexture(cc.TextureCache.getInstance().addImage("sparkle.png"));

I’ve verified that sparkle.png does exist, and when I pass in an invalid path it throws an error.

Is there anything specific I need to do to enable this? I can see that it works fine in the JS tests, and as far as I can tell I’m not doing anything different from what that does.

Any advice / debugging tips will be greatly appreciated

(primarily testing in chrome on a mac, but I get the same behavior in safari)

figured out my problem - unlike cocos2dx, you need to call

emitter.setDrawMode(cc.PARTICLE_TEXTURE_MODE);

before the particle emitter will display textured particles.
