I am going to start working on a new mission, but I need some more info to do it. What I want is the player to go to see somebody, and they will tell him to do something and come back, when they do that and come back, how do I make them give another task or something?
For an example:
Player comes up to Bob, and they talked and player left but comes back, how do I make them talk again on a different subject?
And to better yet, if Bob gives player an assignment, but player comes back without completing it, how do I make Bob either repeat the assignment or say something else?
