That should make the Player start on the "ground" and slowly get up, then regain their light focus. Change AddTimer("trig1", 7.0f, "beginStory"); to any other number value to make it last longer. Ex: AddTimer("trig1", 11.0f, "beginStory"); that would make it last 11 seconds. Hope this was helpful.
For a more realistic lighting effect I'm not entirely sure on, but if you watch greengc035 on YouTube he could be of some help? http://www.youtube.com/watch?v=RGVHE4gsFZ8 he was helpful to me. This video is on lighting, I hope it helps you!
