Adding an explosion particle system

From the resources provided for the chapter, add the smoke.plist, smoke.png, dusts.plist, and dust.png files to the resources folder in the game.

Now, in the GameplayLayer.cpp file, add the following lines of code in the player rocket and enemy collision check right under where we increment the score:

CCParticleSystemQuad * smokeParticle = CCParticleSystemQuad::create("smoke.plist");
smokeParticle->setPosition(en->getPosition());
this->addChild(smokeParticle);   
smokeParticle->setAutoRemoveOnFinish(true);

                  
CCParticleSystemQuad  * dustParticle = CCParticleSystemQuad::create("dusts.plist");
dustParticle->setPosition(en->getPosition());
this->addChild(dustParticle);   
dustParticle->setAutoRemoveOnFinish(true);

Here, we create new instances of CCParticleSystemQuads named smokeParticle and dustParticle. We then give the Plist of the particle that we want to create, in this case, we give smoke.plist and dusts.plist....
