How do I make waves for SP Maps?

[tylerp14]

So I want to make a Single Player map, I know how to do AI In-game and they spawn and all that when I step into the trigger volume, I know how to do hud-messages as well. I want to know how to do waves and nav points. Oh and when I type in "(ai_follow_target_players encounter_2)" in the script they dont follow me, they just stand there, when I do "move locations" for the encounter they move, but they still dont follow me, they do get in my vehicle when I go up to them, and do they have to be on human teams? I have them on player teams because when I put them on the human team they attack me.

Thanks if you can help.
