Typical usage

Vehicle that chases the player

[On Update] → [Vehicle Autonomous:
                   Mode=Follow Target, Target=player
                   Max Speed=60  Stop Distance=4.0
                   Obstacle Avoidance=True]
                  └── Out     ──► [...]
                  └── Arrived ──► [...]  # when it reaches the target

Taxi on patrol route

[On Update] → [Vehicle Autonomous:
                   Mode=Patrol
                   WP 1=stop_a  WP 2=stop_b  WP 3=stop_c
                   Max Speed=40  Arrive Radius=3.0]

Notes

  • The object must have Vehicle physics type in Range Game Engine.
  • The Arrived branch fires every frame while the vehicle is within Stop Distance of the target.
  • Obstacle Avoidance uses lateral raycasts of 7 units — adjust Stop Distance to avoid false positives.
