求助想请大家帮我分析一段代码

我写了一段创建移动目标,并修改替换的代码,不知可否优化,请高人指点:

if (!flyNode.valid())
{
  return 0;
}
osg::StateSet* stateset = new osg::StateSet;
stateset->setMode(GL_LIGHTING, osg::StateAttribute::ON);
stateset->setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
flyNode->setStateSet(stateset);

阿威

实在有点费劲   你能不能用代码模式插入这些东西

还有你的注释  能不能分一下段  清楚的表明你的意图   我耐着性子都看不下去了
