[KillerP90 10]

As the titles says i want an AI to go back and redo his checkpoints like a patrol.

Do i have to make more waypoints or is there coding involded and if so what code do i use and how?

Use the "CYCLE" waypoint type.

Or too elaborate alittle create your waypoints then doubleclick on the player who you're giving waypoints too and select the CYCLE waypoint. :P
