Setup
BP_BaseAI blueprint already has PatrolComponent, so firstly we need to create path using BP_PatrolPath.
Next, connect created patrol path with reference in PatrolComponent.
- PatrolPath - reference to BP_PatrolPath actor
- PointInde - index of point in spline component
- ReverseDirection - whether it should update patrol index by incrementing it or decrementing
To move AI towards patrol index location, use task T_MoveToPatrolPoint.
