Time for action – fit to burst?


If you have game scenes where bullets or other projectiles hit a target, you may have thought of emphasizing the impact with a short fiery burst.

  1. Make a copy of Main.java and name the class Particle5Burst.java. Remember to also refactor the first line of the main() method to Particle5Burst app = new Particle5Burst();.

  2. Copy the included file assets/Effects/flash.png into your project's assets/Effect directory. It includes a sprite animation of a fiery burst.

  3. Since a burst is short and compact, we create an emitter with only five particles in the simpleInitApp() method:

    public void simpleInitApp() {
      ParticleEmitter burstEmitter = new ParticleEmitter("Burst emitter", Type.Triangle, 5);
      rootNode.attachChild(burstEmitter);
  4. The flash.png sprite animation contains a random series of 2 x 2 explosive flashes. Set both animation dimensions to 2, and the image order to random:

    Material burstMat = new Material(assetManager, "Common/MatDefs/Misc/Particle.j3md");
    burstMat...
