Currently in my render() the background colour is set to white but when I change it to white I cannot see my effect at all.

I was wondering whether there was an option I need to enable or a line of code I might have missed?

public void render(float delta) {
    Gdx.gl.glClearColor(0, 0, 0, 1);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

    batch.begin();
    effect.update(delta);
    effect.draw(batch);

    batch.end();

}

//here is the .p file

  • Show the rendering code else we can't help. – bemeyer Jan 15 '14 at 13:03
  • Add it to the question. And please add the effect.p or show us which effect it is, if it's a lot transparent or even white you won't see it. That code is fine for sure. – bemeyer Jan 15 '14 at 13:09
  • so yeh i don't see any option in the .p file that will let me display a particle effect on a white background ? – user3197976 Jan 15 '14 at 13:15
  • also effect is definitely not white it is the default orange and red – user3197976 Jan 15 '14 at 13:18
  • There is nothing like that. If the effect is transparent or the png is transparent that can happen test it with a different particle – bemeyer Jan 15 '14 at 13:18
  • i checked the particle.png (image file) and it is on a transparent background if that is the case then what colour should the background of the particle image be ? – user3197976 Jan 15 '14 at 13:21
  • no that it has a transparent background is fine. Is the effect on a blackscreen white? if so do change the color of it. – bemeyer Jan 15 '14 at 14:04

    Tested it. Meight be a bug of libgdx. With a white background no effect is visible even if you change texture color or stuff like that. But well regulary you should have any background so that shouldn't be a problem. Go ask that question inside of the badlogic forum. – bemeyer Jan 15 '14 at 14:38
  • I thought so because I followed their guides religiously. – user3197976 Jan 15 '14 at 14:56

Disable additive blending in your particle effect.
