cocos2d-x自带粒子系统

1、先说雪花特效。去年冬天看过一款游戏，叫部落啥的，它的地图界面一直都有雪花飘来飘去，那时候觉得真TM高端大气上档次，现在我就呵呵了。

view sourceprint?

1.ParticleSystem* ps = ParticleSnow::create();

2.//因为偷懒，我直接用helloWorld里的close 图片当雪花

3.ps->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseSelected.png"));

4.ps->setPosition(Point(200,200));//生成的雪花从这个坐标往下落

5.this->addChild(ps,10);

演示效果...自己去想象吧。
如果想控制产生场景中雪花的数量，可以使用下面这个接口，下面几个例子也是一样：

view sourceprint?

1.static ParticleSnow* createWithTotalParticles(int numberOfParticles);//参数即是雪花的数量   

2、烟火效果

view sourceprint?

1.ParticleSystem* ps = ParticleFireworks::create();

2.ps->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseSelected.png"));

3.ps->setPosition(Point(200,200));

4.this->addChild(ps,10);

3、下雨效果

view sourceprint?

1.ParticleSystem* ps = ParticleRain::create();

2.ps->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseSelected.png"));

3.ps->setPosition(Point(200,200));

4.this->addChild(ps,10);

4、烟雾

view sourceprint?

1.ParticleSystem* ps = ParticleSmoke::create();//效果实在不咋地

2.ps->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseSelected.png"));

3.ps->setPosition(Point(200,200));

4.this->addChild(ps,10);

5、爆炸

view sourceprint?

1.ParticleSystem* ps = ParticleExplosion::create();

2.ps->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseSelected.png"));

3.ps->setPosition(Point(200,200));

4.this->addChild(ps,10);

6、螺旋

view sourceprint?

1.ParticleSystem* ps = ParticleSpiral::create();

2.ps->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseSelected.png"));

3.ps->setPosition(Point(200,200));

4.this->addChild(ps,10);

7、流星（用彗星来描述会更贴切一点，因为它拖着一条长长的尾巴）

view sourceprint?

1.ParticleSystem* ps = ParticleMeteor::create();

2.ps->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseSelected.png"));

3.ps->setPosition(Point(200,200));

4.this->addChild(ps,10);

8、星云

view sourceprint?

1.ParticleSystem* ps = ParticleGalaxy::create();

2.ps->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseSelected.png"));

3.ps->setPosition(Point(200,200));

4.this->addChild(ps,10);

9、太阳（ 日 ）

view sourceprint?

1.ParticleSystem* ps = ParticleSun::create();

2.ps->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseSelected.png"));

3.ps->setPosition(Point(200,200));

4.this->addChild(ps,10);

10、火焰

view sourceprint?

1.ParticleSystem* ps = ParticleFire::create();

2.ps->setTexture(Director::getInstance()->getTextureCache()->addImage("CloseSelected.png"));

3.ps->setPosition(Point(200,200));

4.this->addChild(ps,10);
