Presuming meta is a Meta Triangle Selector, you may as well just not put all your selectors into a meta selector and instead keep them in an array or something, ie:

Code: Select all

if (smgr->getSceneCollisionManager()->getCollisionPoint(line, selector[0], intersection, tri)
doSomething();
...
if (smgr->getSceneCollisionManager()->getCollisionPoint(line, selector[1], intersection, tri)
doSomethingElse();

Because all a Meta Triangle Selector does anyways is group your triangle selectors into an array behind the scenes.
