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

//plist文件里面有粒子效果的各种参数
//textureFileName对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);

//所有的配置也可以自己写
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);
