I have a character ai that goes from target point 1 to target point 2 I want it to go back and forth constantly would I have to use a loop node?
There is an event for MoveCompleted on the AIcontroller you can sign up for. when it fires you can tell it to go to the next point.
Note that this is pseudo-code. You need to probably do this on Possessed and check if your controller is an AIcontroller if you want it on the pawn, otherwise you could make a custom controller or handle this in the Level blueprint.
