Yes your idea is right. Please see my last edit ( just done ). Its a simple example of that. After a c_trace the closet vertex to hitposition will be saved in hit - entitys skill1. Then a function creates a arrow model ( or whatever ). This one will be placed at position taken from vertex nr saved in skill1. Hope it helps.
