big problem

hey guys i have just completed a game but when i built it the shooting particles(raycast shooting) are not there in the output game(they are when you play it in unity)
Plz help

I don't know what to say.. I've found this http://answers.unity3d.com/questions/647439/where-can-i-find-an-easy-raycast-shooting-tutorial.html. Try to remake it!
