cocos2d-x 3.1.1 学习笔记［16］ Particle 粒子效果

    //plist文件中面有粒子效果的各种參数
    //textureFileName相应着使用粒子的图片
    auto particle = ParticleSystemQuad::create("starFlash.plist");
    particle->setPosition(Vec2(s.width / 2, s.height / 2));
    addChild(particle);

    //全部的配置也能够自己写
    auto p2 = ParticleSystemQuad::createWithTotalParticles(200);
    p2->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseNormal.png"));
    p2->setPosition(Vec2(100, 100));
    // duration
    p2->setDuration(ParticleSystem::DURATION_INFINITY);

    // radius mode
    p2->setEmitterMode(ParticleSystem::Mode::RADIUS);

    // radius mode: start and end radius in pixels
    p2->setStartRadius(4);
    p2->setStartRadiusVar(1);
    p2->setEndRadius(ParticleSystem::START_RADIUS_EQUAL_TO_END_RADIUS);
    p2->setEndRadiusVar(0);

    // radius mode: degrees per second
    p2->setRotatePerSecond(100);
    p2->setRotatePerSecondVar(0);

    // angle
    p2->setAngle(90);
    p2->setAngleVar(0);

    // emitter position
    auto size = Director::getInstance()->getWinSize();
    p2->setPosVar(Point::ZERO);

    // life of particles
    p2->setLife(0.5);
    p2->setLifeVar(0);

    // spin of particles
    p2->setStartSpin(0);
    p2->setStartSpinVar(0);
    p2->setEndSpin(0);
    p2->setEndSpinVar(0);

    // color of particles
    Color4F startColor(0.0f, 0.8f, 0.9f, 1.0f);
    p2->setStartColor(startColor);

    Color4F startColorVar(0, 0, 0, 1.0f);
    p2->setStartColorVar(startColorVar);

    Color4F endColor(1.0f, 1.0f, 1.0f, 0.1f);
    p2->setEndColor(endColor);

    Color4F endColorVar(0, 0, 0, 0.1f);
    p2->setEndColorVar(endColorVar);

    // size, in pixels
    p2->setStartSize(20);
    p2->setStartSizeVar(1);
    p2->setEndSize(0);

    // emits per second
    p2->setEmissionRate(p2->getTotalParticles() / p2->getLife());

    // additive
    p2->setBlendAdditive(false);

    //addChild(p2);
    p2->setPosition(Point(200,200));
    addChild(p2);
