| Jan 5, 2017 at 15:04 | comment | added | eclmist | @johnny, I don't think you understand what I'm saying. First of all, you ask this in gamedev.stackexchange. Not math.stackexchange, or something similar. Of course we would look at it in the context of game development. Secondly, your question makes zero sense if you are looking at it as nothing but points. Game context or not. | |

| Jan 2, 2017 at 10:57 | comment | added | eclmist | @johnny If you consider them as only points, then how would your question even make sense? "Person B is facing the same direction as Person A". How can mere points face anywhere? There has to be a separate vector to say where the points' forward is. | |

| Jan 2, 2017 at 2:16 | comment | added | johnny | This is great. Thank you. What I don't understand is how "if you have the rotation angle of B:" How do I get that? I think I am considering this as stationary set of points, no one is turning. They're just two points on a graph. I don't turn them at all (in this example.) Are you saying, when, for example, someone hits the left button then I get an angle of rotation? | |
