Hello ^^. You should check out the "Engine Scripts" page on the frictional games wiki.
Here it is, in case you have some brain lags : p
http://wiki.frictionalgames.com/hpl2/amn..._functions
Then go to camera functions, and see what it offers ! They allow you to make the player close his eyes, move his head, look at specific entities. About making the player run, it should be possible to make him walk with void MovePlayerForward(float afAmount) but I never used that function. Other members might help you as well.
If you have other questions, I'd be pleased to help you. I have free cookies.
Edit : it's actually called screen effects and player, in the wiki.
