Thanks. I did some tutorials and some of a Udemy course. A lot of web searches, but I tend to learn as I go by figuring things out - and then forget what I did later, unfortunately. 
I am actually doing a mix of C++ and Blueprint, with this particular work part of the C++ code. I realize the original question I piggybacked on was for Blueprint, but I guess it seems that the question is the same regardless. I have extended the APawn to create a custom pawn that I can control movements of using scripted waypoints or other means. I can set the position using Model->SetWorldLocation, so hopefully that is the correct way. It works, but I guess I do not understand why SetActorLocation does not work, and Iām a bit concerned that there may be an issue Iām not aware of. Anyway, like I said, what I have does work, so unless anyone has a comment to correct my misunderstanding, there is no further reply necessary. Thanks again!
