请教OSG 爆炸特效的问题

minghunwu9

我看了<<OSG编程入门指南>>一书中的爆炸特效，其中代码如下：       
                    osg::Group* explode = new osg::Group() ;
        //风向
        osg::Vec3 wind(1.0f,0.0f,0.0f);
        //位置
        osg::Vec3 position(0.0f,0.0f,-10.0f);
        //爆炸模拟，10.0f为缩放比，默认为1.0f，不缩放
        osgParticle::ExplosionEffect* explosion = new osgParticle::ExplosionEffect(position, 10.0f);
        //碎片模拟
        osgParticle::ExplosionDebrisEffect* explosionDebri = new osgParticle::ExplosionDebrisEffect(position, 10.0f);
        //烟模拟
        osgParticle::SmokeEffect* smoke = new osgParticle::SmokeEffect(position, 10.0f);
        //火焰模拟
        osgParticle::FireEffect* fire = new osgParticle::FireEffect(position, 10.0f);
        //设置风向
        explosion->setWind(wind);
        explosionDebri->setWind(wind);
        smoke->setWind(wind);
        fire->setWind(wind);
         这样是能出来爆炸特效，但是这个特效的时间怎么来控制呢？

array

ParticleEffect::setParticleDuration()，等等。ExplosionEffect是派生自ParticleEffect的

1. explosion->setParticleDuration(5.0f);
   
2. explosionDebri->setParticleDuration(5.0f);
   
3. smoke->setParticleDuration(5.0f);
   
4. fire->setParticleDuration(5.0f);

这样似乎没用啊。

array

那说明您自己的做法有问题
