7. Creating Particle Systems | Building Android Games with Cocos2d-x

Adding particle systems to our game

Cocos2d-x has built-in classes that allow you to render the most common visual effects such as explosions, fire, fireworks, smoke, and rain, among others, by displaying a large number of small graphic objects referred to as particles.

It is very easy to implement. Let us add a default explosion effect, by simply adding the following lines to our explodeBombs method:

bool HelloWorld::explodeBombs(cocos2d::Touch* touch, cocos2d::Event* event){
  Vec2 touchLocation = touch->getLocation();
  cocos2d::Vector<cocos2d::Sprite*> toErase;
  for(auto bomb : _bombs){
    if(bomb->getBoundingBox().containsPoint(touchLocation)){
      auto explosion = ParticleExplosion::create();
      explosion->setPosition(bomb->getPosition());
      this->addChild(explosion);
      bomb->setVisible(false);
      this->removeChild(bomb);
      toErase.pushBack(bomb);
    }
  }
  for(auto bomb : toErase){
    _bombs.eraseObject(bomb);
  }
  return true;
}
