this code does not work correctly.
particles can not move anywhere. (works in phaser 2.6.2)

        this.waterParticle = game.make.bitmapData(2, 2);
        this.waterParticle.rect(0, 0, 2, 2, '#ff0000');
        this.waterParticle.update();

        this.emitter = game.add.emitter(200, 200, 500);
        this.emitter.makeParticles(this.waterParticle);
        this.emitter.setXSpeed(-100, -250);
        this.emitter.setYSpeed(-100, 100);
        this.emitter.setAlpha(0.2, 1);
        this.emitter.flow(500, 20, 2, -1, true);

Thanks for verifying it.
Hmm, I actually use this template.

So maybe this template or I made some mistake.
I'll close this issue.
