Helicopter AI

Hey Guys,
Johnny here :smiley:
I was wondering if anyone had or knew how to write an AI script for a helicopter. All it need to do is to follow the player or a game object and it has to avoid the terrain so it won’t go through walls, mountains, etc.
Thanks so much.
P.S - Ill put your name or whatever you want in the credits of my game when it’s done and on the Google Play Store :smiley:

Thanks, I’m sorry about that but i’m new to these forums and I must have posted it again as I wan’t sure if it had worked. Thanks so much :smiley:
